Very easy to view how things are working and protects you from hackers
Pros and Cons
  • "When one of the employees of my customers is using the VPN Client, I have created for them that they will always get a message. When the VPN Client connects to Kerio Control from the outside, they will get an email so they know when they are connected and when they are disconnected what is happening to their network."
  • "After the takeover by GFI, one of the things that Kerio built was MyKerio environment. This has not been very reliable because I get many messages that MyKerio is not functioning. For some reason, there are things that they changed and it is not very reliable at this moment, instead I have to connect to the firewall to see what is happening."

What is our primary use case?

I use it as a service for my customers. My primary target is to help my customers in the best way to protect them from the dangerous things from the Internet. As a solution, it's easy to maintain. The product is a good solver that also depends on good support and its availability of engineers.

I am using the latest version of Kerio Control. It is an old type of configuration with VPN connections. I still like the product very much.

It is mostly installed on the Linux software appliance. That's what I mostly use for my customers.

How has it helped my organization?

Most customers are not able to understand the technology behind it. I am always trying to explain it to my customers. When I show my customers the interface of Kerio Control and all the reporting features along with the security features within the logging, they're very impressed. I have a very good relationship with my customers because this is mostly based on trust. I show them, and if they have doubts, I always say, "Just hire somebody to check my work." For example, a year and half ago in the travel industry, there were new rules for travel agencies who give out credit cards that they must comply with PCI DSS standards. There were some things that had to be adjusted and Kerio was able to adjust for that. So, it met the demands of PCI DSS standards.

When one of the employees of my customers was using a VPN Client, I created it so they will always get a message. When the VPN Client connects to Kerio Control from the outside, they will get an email so they know when they are connected and when they are disconnected what is happening to their network. I can, as an administrator, look in the logging and see what's happening. If I really wanted to manage what is happening over a month, then I could go deeply within Kerio Control and make a text file of the logging. I could then order an export to Excel to give the customer an impression of what is happening.

Our customers don't want to worry about their IP. If it's implemented well, Kerio Control is very good product for this.

What is most valuable?

  • Security
  • Ease of use
  • Ease of install
  • Ease to recover
  • The load balancing is very easy to maintain.

The login appearances are very strong. In case of problems, you're able to find anything you want. I am always able to help my customers. I really love this product. It's very good. With its many features, there is no comparison. Over the years, I have seen other types of firewalls but they don't have these functionalities within them. 

You can create your users, groups, IP addresses, IP groups, and make rules. It can do protocol inspection and load balancing. You can have a backup line where all kinds of scenarios are possible. 

It has security features, like an open source Internet protection system. This is well-known and a good solution to protect you from guys who try to hack systems. They have also integrated a fire scanner, a protocol inspection, and web content filter. You can adjust things depending on the types of organizations who are using it. Over the years, it has been very easy to maintain. 

I haven't seen anything else that compares to the comprehensiveness of its security features because I'm working mostly with small to mid-range offices. Manageability is very important, and that is possible with it.

Kerio Control's firewall and intrusion detection system, Snort, uses tables that are available on the Internet and loads them automatically. Over the years, I never had problems with my customers. The stability is very important for the product. I use Kerio Control as a central security system for my customers. On the workstation, I mostly use a virus scan. There are also multiple virus detections through your firewall. 

The VPN Client for users is a strong feature within Kerio Control. An important thing within the VPN Client is it also has the possibility for two-factor authentication, which I really like. For some customers, this is very important.

I like its malware features.

This is a very robust the product.

What needs improvement?

With Kerio Connect, they blew it. They were not able to pace up with the competition. I am working with a variety of customers: lawyer offices, travel agencies, big shopping mall accounts, and small accountancy offices. They have all kinds of needs. Kerio Connect did a new launch in the Netherlands for the ACG and GDPR, which are very strict for some companies, like lawyer offices. It is important within the mail server product that you're able to encrypt your attachments and have two-factor authentication. All these type of things are not within Kerio Connect. Therefore, this product is not interesting anymore for my customers since the Dutch law is that strict. For example, there was a judgment from a judge this year when a company was hacked. There was a guy who maintained this network gave some advice to the customer, but the customer would not pay for that solution. He was held responsible for about 60 percent loss of this business, because there was a ransomware within in the organization. These are the things we have to deal with in the Netherlands and in Europe. Within the Netherlands, this is a very important thing, so you can probably understand how important it is that the product is okay with the market demands.

After the takeover by GFI, one of the things that Kerio built was MyKerio environment. This is a cloud solution to have an overview of the statuses of all the firewalls that you maintain. When a firewall or primary interface goes down, then you get messages. It also has an app for iPhone or Android. You can then have a quick view about the status of the firewalls for your customers. If there is a problem with the Internet connection, whether it is down or there is an update, then you get a message. So, I can proactively help my customers. However, after the takeover, this has not been very reliable because I get many messages that MyKerio is not functioning. For some reason, there are things that they changed and it is not very reliable at this moment, instead I have to connect to the firewall to see what is happening.

MyKerio is a cloud thing where you can easily see all the firewalls that you maintain for your customers along with the statuses behind them, providing a way to securely connect to your firewall appliances. This is a very strong feature of MyKerio. However, nowadays, I'm not really impressed about things they do with it. That needs improvement in my opinion.

Another thing is that you must be a specialist, like me, when you want to have more specific information, e.g., when there are incidents or things that are happening that need investigation, then you need to go to the shell prompts and logging, where you can perform anything. You can edit anything out of your log files. However, this is not possible within the Kerio Control admin interface. You can only search for one thing, but not for many things.

Kerio Control has a very good future, but it needs good marketing and knowledge around it.

For how long have I used the solution?

I have been working with it since the beginning (1997). When it started, it was called WinRoute. Now, the name is Kerio Control.

What do I think about the stability of the solution?

It is a very stable product, which over the years has been very good. 

What do I think about the scalability of the solution?

The scalability is good. The VPN connections may need improvement. Because of all the security features within Kerio Control, e.g., it can do a deep packet inspection, this can slow down the traffic. Sometimes that creates a problem. For example, Kerio Control offers protocol inspection for the services that are available, and sometimes that gives problems because people are complaining that it is slow. The VPN connections from remote are not always very fast, so I think the throughputs of the VPN need improvement.

How are customer service and support?

In every software, sometimes there are problems. One of the strong things about Kerio was the support knowledge and the involvement of the employees within the support department. I used to have the impression that the people working there were part of the products. It was almost a pleasure to have contact with people who were really involved with the products. After the take over of Kerio Control and Kerio Connect by GFI, it was really disastrous because a lot of the people involved were gone. When I had a problem and I asked for support, then they are asking me questions that I think help, but they don't understand the product. This is logical, of course, because there was a takeover.

The GFI product support for Kerio Connect has been unacceptable for my customers and me because I had major businesses that were running with this software and very satisfied because of the user-friendliness. Error and problems cannot be cured, but they must be solved. For example, when I perform an update, the next thing will be a ruined email system, but nobody will be available for support. This is also when they know that an update is coming and I am calling after updating it. They promise to support us, but there is no support, which is terrible. This is the thing that I feel is very important when you use business-critical software, and they need to improve on. I want to be able to call their support and reach someone who has knowledge about the product. 

It has a very sophisticated logging system. I need to be able to connect to the engineers behind it, who develop it, and tell them, "Okay, that's wrong." If I'm not able to connect to first level engineers and make them understand that they're not able to help me or they need deeper knowledge of the product, then there is a problem. While this is not an issue with Kerio Control because they have proven with the product that they are able to maintain it, the major problem for me with Kerio Connect was they ruined things in the past and I was unable to go back. So, I'm very interested in how they are improving the support to make things work again with MyKerio, as it is very good feature.

Which solution did I use previously and why did I switch?

I have worked with all the firewall systems, like Cisco. I see how people struggle of with it and also how much effort it takes to maintain it and implement rules. Kerio did a very good job with that. You can also, in a quick way, see inbound and outbound traffic and make your own filters.

How was the initial setup?

A basic initial setup is very simple and straightforward. They offer a straightforward set of rules to make it work, then you can create all the rules you need for the customer depending on their demands. It can do almost anything.

The deployment time frame varies. For example, if I am deploying to a shopping mall, that shopping mall has all kinds of offices. Every office has its own demands regarding the IP system that they use. Every shop has its own software supply and concepts. Sometimes things get complex, then I start from scratch to make sure everything is maintainable, but this is very easy in Kerio Control if you know how to do your job.

Because of the coronavirus, for people who want to work at home, it is very easy to set up VPN Clients because that is a piece of cake.

What about the implementation team?

When you look at Kerio Control, they are able to maintain it in a way that I had no problems because I was always careful with updates. I first test them on-premise before I roll it out to my customers. That's also no guarantee, but we are able to maintain it in a good way.

Implementation strategy changes per customer. Some customers have very strict policies about the sites that they can access via the Internet. Others have limited bandwidth. For example, I had a customer who could not visit some Internet sites because most of my customers have two Internet connections. I found out that connecting through the other interface wasn't a problem. It had to do this with the networks between them. It's very easy in Kerio Control to make another path where another Internet connection is used for that website.

I built a large network of freelancers over the years in the Netherlands and foreign countries to get the best solution for each customers. I am working with all types of people who are trustworthy and have good knowledge of the product. I tell my customers, "The IT world is the same as the medical world. You don't go to a heart specialist for an eye operation, and you don't go to your normal doctor for a heart operation. They're all specialists on their specific terrain." That is the way I operate for my customers.

I handle the deployment and maintenance of Kerio Control myself.

What was our ROI?

I have seen ROI over the years. It is part of the complete solution that I offer to my customers. Over the years, it has offered me a reliable platform for my customer and allowing me to build trust with my customers. That's the most important thing of Kerio Control.

If the support is not good, then I have a problem with my customers and it will cost me money. That's one of the things that GFI did after the takeover: It cost me a lot of money. Because there were a lot of problems, not with Kerio Control, but with Kerio Connect. It really cost me with unsatisfied customers.

What's my experience with pricing, setup cost, and licensing?

It's not a very expensive solution from my point of view. Because it is not only about buying a product, but how much time does it cost to implement the features that the product offers? I haven't found another product that is able to do the things that Kerio Control can do for the money. 

It is a good fit for SMBs because of its maintainability. When you want to keep your costs low, then Kerio Control is a very good solution. It's not an expensive product that is well integrated. It has a complete set of features within it that make it a very strong product.

GFI has made a stupid decision regarding small office licensing. For offices where there are only three to five employees and had five years towards a five user product, they now force these customers to a 10-year user license. I really don't understand it. It's a stupid decision for the small offices who want a good solution for security because they'll probably decide to go to another product. Why should they buy something that they don't use?

I don't use the Kerio hardware because they're too expensive and difficult to maintain.

Kerio Control has the ability if you buy it (it's a separate option) to know malware sites. Then, they will be blocked and the user is informed.

Which other solutions did I evaluate?

I have used Cisco, FortiGate, pfSense, and then more simple router things that have integrated software. However, mostly in business, I don't want to use just a router with integrated software. I don't believe in that concept. My customers are of a size that the stability of the product and the way it is maintained are very important to me. That's one of the strongest things about Kerio Control. It has proven to me over the years, and with my customers as well, that it's a very stable product. I haven't seen another product that compares to it within its price range. However, I also have to help my customers when they are having problems when connecting to a site or when they are having problems in general. When I contact their IT to find out what's happening on their side, it is difficult to get an answer why things are going wrong.

I can't find a comparable product to Kerio Control that offers the same set of features for the same money.

I found another product that can do a lot more than Kerio Connect, and that's IceWarp. IceWarp is a very strong product. IceWarp is a really strong competitor within this market. I was impressed with the software's ease of use because it's completely web-based. It's not only a mail server product, which offers secure attachments with out-of-the-box Office, but offers two-factor authentication. It also has a web-based text editor and Excel sheet, where you can make a basic presentation. With the same interface, there is the possibility to do OneDrive or Google Drive. They built it with the same depth that you need to log in to your IceWarp environment as a user. You can store your documents and sync them with a Mac or Windows PC. However, there is not much to find about this product.

What other advice do I have?

Kerio Control is very good. The way that you can maintain it, it's very easy. I had an employee who built a copy of the product, which was a very basic interface for the open source community. You can find it on the Internet. He was impressed by the way Kerio built this firewall solver, because most firewalls are very difficult to maintain due to their complexity. If you are working in complex environments, it is not easy to maintain firewalls, because things are always changing. This is the part of Kerio that is very good.

Every IT guy that I show the interface of Kerio Control is impressed with the product because it's very easy to view how things are working (when you know what you're doing).

Ransomware is protected only when the system is able to detect, "Okay, this is coming from a link and that link is known, and it is within the protection."

I don't use the solution’s high-availability/failover protection because the hardware is needed as well and I wasn't able to test it. I want to test it first, because it's not only the testing, but what are the costs of ownership for the customer? Over the years, the Internet connections in the Netherlands are very stable. I always tell my customers that if they have an Internet connection that they should have a backup connection. The hardware that I use is mostly recent, stable hardware. So, it's not for my type of customers. This is not a very important feature because the hardware is well-maintained. However, that's a thing that I take care of since most hardware fails because there is not a good cooling environment or a lot of dust is in hardware. I make sure that things are running well as part of my services.

I'm still surprised that sometimes I need something which I thought was not within Kerio Control, and it was within Kerio Control. That's mostly the case.

Biggest lesson learnt: Stick with suppliers for software products who are able to give very good support.

I would rate the product as a nine (out of 10). It is very good.

Makes it easy to manage and add settings to the firewall, and gives us a single point to manage global rule sets
Pros and Cons
  • "The traffic insight page or the administrative portal is really helpful because you can see all the internet usage down to the point where you can see if it's big files or streams. It gives us a good view of what the internet usage is of users who are coupled to an IP address. That way, if there are problems with, for example, a lot of data usage or problems with the connection, we can narrow it down to a single user or server and address the problem. It's really helpful for diagnostic data."
  • "If you have to dive deeper into the firewall or any other features, then you really have to read up a bit about how to set it up properly. Some of my colleagues, in the beginning, jumped in and made a bunch of rules but then it got really messy. If Kerio had a template or guidelines for best practices, at the beginning, that would really help. With Kerio Control it's basically 'find out for yourself.'"

What is our primary use case?

We mostly use Kerio Control as a virtual firewall solution, and the user accounts let people have access to the internet through the firewall. We also have a few cases where we use the VPN. But it's mostly a firewall solution with multiple VLANs and the network behind it.

It's deployed on-premises, both virtual and hardware solutions. The NG100 is the smallest solution for smaller businesses, but we mostly use the virtual appliance.

Most of our customers are small to medium companies, where there are between five and 40 work spaces. Everyone has a PC and they have a VoIP phone and their own phones, and they have tablets. Most of the time, it's one to four devices per user. The biggest client we have is around 30 users.

How has it helped my organization?

It has made it easier for us and our employees to manage and add settings to the firewall, as opposed to another brand where you have to use command-line or really complicated layouts. The ease of use is a big plus.

The solution has also saved us a lot of time in managing security. We have to adjust the content rules and now we have one place where we can enter them. We have a customer with about 20 Kerio Controls and we don't have to set all the rules on each firewall. When we have to add some rules to each of the firewalls, it can be done within one minute. Normally, it would take 20 to 30 minutes, depending on if they're all online — and we would have to check them manually. Now, we just have to enter them and, when they come online, they sync with the global rule sets.

What is most valuable?

The traffic insight page or the administrative portal is really helpful because you can see all the internet usage down to the point where you can see if it's big files or streams. It gives us a good view of what the internet usage is of users who are coupled to an IP address. That way, if there are problems with, for example, a lot of data usage or problems with the connection, we can narrow it down to a single user or server and address the problem. It's really helpful for diagnostic data.

The content filtering is pretty good for our needs, especially with the global rules you can define. We can define global rules and use them on multiple Kerio Control installations. So we have one place to set all the rules for different customers. That's very good. The rules that it auto-updates and that are automatically available — for example, spam or indecent websites, or whatever else is in the firewall by default — are good.

The VPN works pretty well, especially with the Kerio Control VPN software. Some products don't have their own VPN software and, with Windows, sometimes it's just better to have a piece of software. That's especially true for some of our customers because they only have to open the software and press "Connect." Windows can be a little bit weird when it comes to that, and it breaks connections. You really don't see when Windows loses a connection or if you have to reconnect. The Kerio Control VPN client is pretty good at that.

What needs improvement?

The antivirus is either on or off, but we can't really see or measure how well it is doing. Sometimes we get the feeling that some files get past it and then they get caught on the antivirus of the client PC. We would like to have more control with the antivirus.

Also, we have multiple employees working on firewalls and if one employee changes a rule and traffic that shouldn't be there suddenly comes through the firewall, it's hard to pinpoint which rule is affecting that traffic because there is some overlap. It's not clear if it's getting past it because it's not decrypted. It needs more logging or more in-depth diagnostics about which traffic is hitting which rule on the firewall. Sometimes we have 20 or 30 rules and it becomes a whole job to figure that out.

When it comes to QOS, the quality of service, you have to set a fixed bandwidth. But sometimes, when we have multiple connections in front of it, it's a fallback line. For example, when we use Kerio aboard a ship, there is the satellite connection but there is also a 3G or 4G connection. We always have to set a fixed limit for the connection. If we set the fixed limit to 4G and it switches to navigation, one user can use up all the bandwidth for the entire ship. It would be better if there were something more dynamic, where it could sense the total and we could use percentages. For example, we could say a user has always 5 percent of the connection. But now we have 5 percent of a fixed connection number. The fixed limit on a line for QOS is a problem because we don't always know which connection is in front of it.

Also, if you have to dive deeper into the firewall or any other features, then you really have to read up a bit about how to set it up properly. Some of my colleagues, in the beginning, jumped in and made a bunch of rules but then it got really messy. If Kerio had a template or guidelines for best practices, at the beginning, that would really help. With Kerio Control it's basically "find out for yourself."

We've also had some problems with how to set the rules, but that's when more than one rule is overlapping and cancels out all the other rules. However, that's more our fault.

For how long have I used the solution?

I have been using Kerio Control for around six years.

What do I think about the stability of the solution?

It's pretty stable. We had some problems with Kerio Control virtual appliances. If it was running more than 20 days, it would become really slow and sometimes it would just stop working. When we rebooted the solution it would come back up. But that was something that was happening a year-and-a-half ago. Since then, we haven't had any more problems with it. 

We had a few solutions that just went corrupt. We're not sure if that was the disk or Kerio itself. We always have an installation of the virtual appliance on the server, so we can set up a new one, load the backup back in, and be up and running again in 15 minutes.

How are customer service and technical support?

It's been a while since we contacted support, but back when we did it was pretty hard to get a hold of someone. We didn't get a lot of feedback. Most of the time, it was, "Look at the documentation." It was hard to get someone to look over our shoulder and help us with the problem. I think that was before GFI took over.

Which solution did I use previously and why did I switch?

We did not have a previous solution. 

How was the initial setup?

As I said, if there were best practices or a template, the setup would be a lot easier because you start and then you change the setup according to what you think is right. But later on, when you encounter problems and look in the documentation, you see that another way is better. That was a bit of a problem when setting up. It all works, but in managing or adding rules, for example, or we just didn't do it properly. It was a bit of trial and error and that was a problem. It's too much trial and error when you start.

Deployment time, for some customers, is fairly quick. A basic setup can be up and running in 15 or 30 minutes. With other customers that have a lot of rules we do testing so it could take three or four hours.

For our implementation strategy, we just look at what the client wants. For some clients, we have a basic template now, where we always use a backup from an existing Kerio. If it's a new customer, we check if we have an existing Kerio that's pretty much the same, or we just do it from scratch if there aren't too many rules or networking behind it.

What was our ROI?

We see ROI because the ease of use is a lot better, so we spend less time on maintenance, administrating, changing rules, and checking usage.

What's my experience with pricing, setup cost, and licensing?

If you have a lot of users, the licensing can be a bit of a problem because we have a lot of customers who don't use the user feature, but we have five devices per user, and we have to extend the license every time. The fixed model of users and devices is a bit of a problem for us. We want to be able to expand it fast and not have to contact our supplier first to get a license. That takes another one or two days and the customer is waiting.

It might be better if they offered a fixed monthly or yearly price instead of the user-based price. That's really keeping us from deploying with some of our smaller customers or customers that have a more dynamic user base. If they had a larger fixed price with unlimited users or devices, that would help. Now, it's five users each time. A pack of 100 or 200 users for a certain price would make it more dynamic and user-scalable.

Which other solutions did I evaluate?

We looked at pfSense and some paid firewall solutions, but in terms of how user-friendly it is for our employees and my colleagues, and how well we could manage it from a remote portal, Kerio Control was better, in our opinion.

What other advice do I have?

Kerio Control is a nice-to-have for a small business like ours.

My advice would be to look at best practices or get someone to show you how to properly set it up before you try anything and it gets too messy. The biggest lesson I have learned from using this solution is to look out when it comes to firewall rules. Don't use too many firewall rules or content rules because it can get really messy, really quickly, if you don't have a decent strategy for that.

We always try to use auto-update, so most of the time we're on the most recent version. We have some examples where we use Kerio Control aboard ships where the bandwidth is really limited. In those cases we use our own timeframe to update Kerio Control, but it's normally done within a month or two, so most of them are up to date.

We haven't seen anything yet in the antivirus and we haven't had any problems with malware with our systems. I don't know if malware is being detected that well, because sometimes the clients still have some malware. I don't know if it's because it's an HTTPS site or something else.

In our company, most of the work with Kerio is done by about 10 people. Everyone does the same tasks: administrating, changing rules, and installing new Kerios. I work on it in my role as a system admin team lead and developer. As of late, I've been more of a developer than administrator. The others are system administrators, business consultants, and there are two other developers.

The security has been very good and the VPN connections are reliable in that they stay up
Pros and Cons
  • "The most valuable feature is the reliability of VPN capabilities. The VPN has been very reliable and secure. The security has been very good and the VPN connections are reliable in that they stay up. We don't have a lot of problems with downtime and that type of thing."
  • "One of the problems we do have causes problems with the VPN. The software slows the throughput down too much. You could have a one-gigabit connection from the internet, and it slows it down to the area of upload and download is extremely slow. There's too much content filtering at that point."

What is our primary use case?

We have our server in our head office, so we have offices that log into it from various other cities and run their accounting software on it.

How has it helped my organization?

We have several offices in different provinces across Canada and because of that, the connection has been very secure and reliable. We haven't had any downtime with it other than when we had the NG100 fail. Other than that, it's made the connection to our websites, our office, and our eCommerce sites all very reliable. That's been very important.

What is most valuable?

The most valuable feature is the reliability of VPN capabilities. The VPN has been very reliable and secure. The security has been very good and the VPN connections are reliable in that they stay up. We don't have a lot of problems with downtime and that type of thing.

The comprehensiveness of the security features is extremely good. 

Kerio offers everything I need in one product. 

The firewall and intrusion detection features are good. We've had some intrusion attempts that were stopped. The firewall has been doing extremely well for attempted hacks, as well as working well with the intrusion protection.

The VPN features are good They have a solid VPN client, which we found to be extremely good and reliable on various operating systems. Other than that, the VPN has been good. 

Kerio is extremely easy to use. They're easy to install and pre-configure. If you have to do any maintenance it's well handled through the system. Remote connection, logging in, and doing changes on the system is extremely well handled.

We do use the failover in our head office. The failover is working extremely well. The last test on that was May of 2000 and 2020. The failover seems to be working well and the security has been good, so they've felt very confident in having it up and working as it's supposed to be. It's configured as per the instructions and it's working really well.

Kerio has enabled us to double the number of VPN clients extended to those outside of our environment. It started a little bit before the pandemic but just because some of the companies started to work more from home to cut down on costs. But since COVID that's where it shows it's doubled.

What needs improvement?

One of the problems we do have causes problems with the VPN. The software slows the throughput down too much. You could have a one-gigabit connection from the internet, and it slows it down to where the area of upload and download is extremely slow. There's too much content filtering at that point.

Quality control is another problem that needs to be handled better, particularly in the NG100 series. We have had to replace a couple of those. Other than that, the throttling down of the speed is too much. It is too heavy.

Other than that, I think they're good. 

For how long have I used the solution?

We first started with Kerio back in 2003.

We have an NG300, NG100, NG300W, and we still have a couple of 1120s.

What do I think about the stability of the solution?

Other than the quality of the NG100, stability has been extremely good.

What do I think about the scalability of the solution?

The scalability has been extremely well handled. We can very quickly figure out what size of a machine a customer needs and put it into position.

We have four people that do them, but usually, when we're shipping out, one person sets it up and then they deploy it remotely and have the customer follow their instructions remotely.

We don't have plans to increase usage because of the problems we have encountered with the company and the follow-up. We would have. We had quite a few of them, I don't know an exact count anymore because it's changed over but even now we've still got about 32 of them in use right now. But we've switched over probably triple that away from it.

How are customer service and technical support?

GFI's technical support is improving but at the very beginning, it was very bad. There was no way to contact them. When you did call, you didn't get returned messages. It is improving, but it's still not at a level where we're happy with it.

Which solution did I use previously and why did I switch?

We previously used SonicWall. We were looking for something that was really rock solid. We had a very bad experience with SonicWall and their support was very bad. We had a client that was down and they couldn't and didn't help us. We had to find something else in a hurry. 

One of our technicians had been reading up on Kerio so we brought one of their machines in and configured it. That's one of the first ones he did and he said that the setup was really good. He installed it and got the client back up and running, and then we started looking into it and found it was much better. Strangely enough, shortly after that, the sales rep we were dealing with at SonicWall left and he went to Kerio also.

Something that really bothers us about GFI, is that as a partner or a reseller, they believe that the customers belong to them. As a reseller, we take a lot of time building trust and confidence with our clients. We've been in business 30 odd years, and we still have clients with us that we took on back 30, 32, 37 years ago. They're still our clients, they deal with us, and they trust us. SonicWall did it and now GFI does it. They insist on all of the contact information for our customers if we sell them a machine. Then they start direct emailing them and our clients start saying, "I hired you to take care of this, why are these people sending me all this junk?"

Plus, we're in Canada and they send out this information and emails and it has U.S. pricing on it. They make a big deal about that it's only $100 or something, and then by the time we convert it to Canadian, we're looking at $135 and the clients forget that very quickly. It's very misleading to clients. Our customers don't like it. That's one of the other reasons that we're moving everybody from Kerio, because of what GFI's policy is of insisting on having all of our customer's names, addresses, phone numbers, emails, and everything else.

How was the initial setup?

The initial setup is pretty good. The guys are used to it now. They've done a fair number of machines and they're very used to it.

It has become familiar and they're consistent from one model to another. The instructions are straightforward and a good tech should have no problem with it at all. The thing is that they're not a home machine, they're for business. If it has a tech working on it is no problem at all. It's quite simple.

An average deployment takes two and a half hours. 

Network engineers set it up. Even one of our web developers has set up some of them. They have been very happy with training other people to do them. They don't have any problems. It's quite simple. The engineer was the first one to start working with Kerio back when we took them on, and he found that even in the beginning, from learning on his own, it only took him about four to eight machines to feel confident that he could do it without having to follow the instructions every time.

The size of the companies we work with vary. We call them medium-size, but some of them are only one location with 5 to 20 employees. We host a lot of our e-commerce systems and clients have those on their machines so that when the e-commerce inquiries come in, they go through that router. They become a medium-sized business very quickly because of the amount of business they're doing.

Kerio is a good solution for companies of this size. It comes down to the same thing, reliable, cost-effective, the VPN connections are good for the security between the e-commerce sites. Our eCommerce site is dynamic, so it's connected between the customers' inventory, warehousing, shipping, and billing system, directly to the e-commerce site. It makes it a lot tighter and more security is required because they are connecting directly to the customers' business machines, as well as just e-commerce hosted sites. Reliability and security are very highly needed because it does run their e-commerce sites. 

What was our ROI?

We see ROI through the ease of setup. We have a flat fee for configuring one, we charge for one before we ship it out for installation or go and install it. A customer pays the retail price, converted to Canadian at the current exchange rate, and that's what we charge the customer for the machine based on Kerio's MSRP. Then we charge them a flat rate for configuring it, which is two hours and we charge them for two hours labor. Then we charge them for whatever time it takes to do it remotely on-site, or if we're going on-site and having to install it, we charge for that time. If you charge for your time and the value, then you're going to make a good return on it.

But if you go in undercutting prices, something has to suffer. We have never had a customer say to us that they're upset because we haven't taken care of them if they have a problem with one of the Kerio devices. There have been issues, they're machines, they're going to break down. But we've never had a customer say that it wasn't taken care of properly by us. When we had SonicWall that was a problem, we took care of the customer, we couldn't get the machine that he should have had properly under warranty, so we just went and got him a different machine, put it in and got him up and going.

That's where we have to charge for it. We did charge the customer for that, but he felt that we provided the service he needed. It just gave him a very bad taste in his mouth because he couldn't get it under warranty. Undercutting prices, either in your services or your pricing of the hardware is what's happening now on the internet, we see that people are buying Kerio cheaper. We say to them "If you insist on buying it and want us to install it, we're going to charge you to install it, and if there's a problem with DOA or anything like that, dead on arrival, that's up to you." We hand it back to them and say this machine's got a problem, you have to get it fixed.

What's my experience with pricing, setup cost, and licensing?

The pricing is good. Our businesses have been around a long time and we've done that by not being the cheapest, but trying to be the best or one of the best. There's a lot of very good software and hardware companies out there, but a lot of them try to just undercut pricing and try to get the deal. We do not do that. We have a feeling we know what the value of our product is, if it's our own product. In a case where we have a router system, we know the value of it, we know what the value of the software licensing is for renewal and for the initial startup. We look at those things at the beginning, and we felt that Kerio was well in line. The price seems to be going up now, it hasn't gone up as bad as some of its competitors yet, but we'll keep an eye on that. Right now the pricing is valid for the product and the service they get.

Which other solutions did I evaluate?

We did look at and we're also an authorized Cisco reseller, but they're doing the same thing as SonicWall now. These big companies forget who puts all the work in. What they're trying to do, in my opinion, is get the little reseller to go out and hire the right people and go out and move their product, get them installed, and then they want to start going to them directly. I understand that smaller companies come and go but we've been here 37 years in total. They shouldn't go to our customers and start trying to direct sell to them and that type of thing. 

We were also a Dell reseller and we quit because we had to register every sale with them, and then they were going direct to the customers. It's not fair to the company that's gone out and done all the work.

What other advice do I have?

The machine is a good value for the price and the software is extremely good value for the price. It's proven out to be good, but we're just disappointed in the company that now owns it and took over from it. They're improving, but it took too long to improve and it cost us a lot of money in that way. But I can't blame it on Kerio, I have to blame it on GFS.

I would rate Kerio Control a nine out of ten.

The comprehensiveness of the security feature is exceptional but speed needs improvement
Pros and Cons
  • "Kerio is a lot clearer to set up to do particular things, whereas when I do it on a Cisco or a FortiGate I have to go fight with it per week sometimes to do something I can do in 20 minutes on Kerio."
  • "The overall speed needs improvement. Internet connectivity speed needs to be improved somehow."

What is our primary use case?

Our biggest customer uses Kerio Control as a VPN on a campus network that we use to encrypt all of their heating and air. It's at the University of Mexico. It controls all of their heating, air, and security over their campus network. I have a hundred units doing that.

How has it helped my organization?

I'm a one-person team, and Kerio Control has saved me time. When I looked at the comparison between how much time I spend supporting a business installation of Kerio versus a FortiGate installation, just with the implementation, I have saved a few weeks of time. On a yearly basis, I have saved around 30 to 40 hours on one customer because they're bigger customers.

What is most valuable?

The VPN is the most valuable feature. We filter out outgoing NAT packets by port. So we locked down incoming and outgoing packets with the Kerio software. It's a lot less money than our FortiGate solutions that we installed, for instance. The value in it is money savings and flexibility.

Kerio is a lot clearer to set up to do particular things, whereas when I do it on a Cisco or a FortiGate I have to go fight with it per week sometimes to do something I can do in 20 minutes on Kerio.

For the money, the comprehensiveness of the security feature is exceptional. The next level of security is the sandbox and FortiGate charges me $120,000 a year for that sandbox. I don't see that as something that Kerio would ever be adding. The next step is a big, drastic step up in company size. So for medium and small businesses, I think Kerio is about as good as I can get.

It gives us everything we need in one product for our small-size business.

For medium to small businesses, the firewall and intrusion detection features are very well priced and just excellent. The functionality for the amount that we're paying for them is excellent.

The malware and antivirus features are okay. I add stuff on top of Kerio, I have Malwarebytes. So I would give it an okay. Malwarebytes still catches quite a bit that Kerio doesn't.

I used the content filtering a little bit and it works alright. I've got a hundred VPNs at the University of New Mexico. I don't put it anywhere else though, so I don't know. I don't really have any kind of input on that, I suppose.

Their graphical user interface that allows me to open up particular ports to particular internal IPs with one external IP is very flexible and easy to use. It is also much clearer than when I go into my larger systems with two competitors, Cisco and FortiGate.

Kerio enables me to use one external IP address to cut it into multiples server solutions based on different port numbers. It saves them money if my customers are creative enough to use those features.

What needs improvement?

The overall speed needs improvement. Internet connectivity speed needs to be improved somehow.

If I buy one of Kerio's hardware boxes and put it between me and the Internet, the speed is reduced dramatically using their hardware.

For how long have I used the solution?

I have been using Kerio Control for the last twenty years. 

We currently have one on Macintosh and one on Windows of the most current version of Kerio Control as well as Kerio Connect.

What do I think about the stability of the solution?

I found it to be fairly stable. Their updates have gone very smoothly, which is a nice thing. It doesn't crash during updates. I've had very good luck with that. Whereas I can't say the same thing with both Cisco and FortiGate.

What do I think about the scalability of the solution?

If you buy their hardware box, it doesn't scale so nicely. I found if I put it on a higher-end computer, it does better. I guess it's okay if you put the right hardware in for it. I can't get through those to their boxes.

I had some customers that were running about 200 to 300 machines, those were my larger ones with Kerio. For the most part, I have them on between five and 20 users.

How are customer service and technical support?

One of my customers had some issues that weren't pleasant. Support was pretty good and then it changed quite a bit when Lifeboat and GFI were involved. I personally haven't done too bad. I'm a one-person show, but I have a bunch of subcontractors. I personally have done alright with them. Although some of my people have had some not as good experiences over the last six months. They had time-related issues, about how long it took them to get back to them.

How was the initial setup?

On average, it takes around one to two hours on a small to medium business to set it up. But it's totally dependent on their applications and that can vary up to quite a few hours if they've got some complex application issues. Typically, it's because I have to wait on getting responses from vendors. So we go out and we put in a default setup and modify off of that.

Our default setup pretty much locks their network up to only having HTTP, it turns off FTP and things of that nature. We have a pretty secure default setup and then we go open things.

After you've done it a few times it's pretty smooth.

What was our ROI?

Our ROI is money savings. We bill them every year for their renewal subscriptions, and that goes fairly smoothly. We don't have to spend a whole lot of time trying to figure out how to add a particular port or interface for a new function that the client needs to have access to. They never need the Internet. It takes us considerably less time to do it on Kerio than it does on the competing products that we also deal with. Which, from our perspective, is appropriate. For some people, it would be a mixed blessing because you are not getting as much billable time out of it, but we like to be as efficient as possible and so we appreciate that. We feel it's a good return on investment.

What's my experience with pricing, setup cost, and licensing?

I think that licensing flows pretty smoothly. Make sure that you set them up so you support them over the my.kerio.com web interface because that lets you see all of your customers.

What other advice do I have?

We don't use high availability or fail-over protection. We set one up once and almost gave up on it. You have to have pinnacle boxes and things, so we did set it up and test it but we haven't actually sold any of them.

I feel pretty comfortable having a Kerio firewall in a medium to small business. It can be deployed in an easy fashion, which is the same as everybody's Comcast, CenturyLink, or whatever their modem has. Then if you really spend the time doing it correctly, you can give somebody what, I feel, is an enterprise-quality solution in small business for a good price.

If I pinhole Kerio for small businesses, I would rate it a 10 out of ten but overall, I would give it a seven.

If one connection goes down, it automatically switches for me
Pros and Cons
  • "The routing of the multiple internet physical routers I have is the most valuable feature of this solution. Instead of me physically unplugging a cable from one router to the server, if one connection goes down, it automatically switches for me. So I can have all three of them plugged in. If one goes down, it just picks up the other one automatically. There's no physical cable swapping."
  • "I would like it if the interface section had multiple failovers. Although I do have three connections, just in case our physical cables get disconnected, I can only set up one failover as a backup. So, if for some reason our fiber and our AFM went down together, I would have to have it search for our 4G modem. I'd love to have extra backups running."

What is our primary use case?

My primary use case is to route traffic and route our multiple Internet interfaces. It routes all of the outbound Internet traffic, none of the internal. I do apply a content filter as well to make sure people aren't going into places that they shouldn't be. We have some traffic rules setup for certain services, blocking certain IP ranges from getting external access as well. We do the same for the Adelaide office, but our South Coast office, in addition to all of that, we also run DSCP off of it. The South Coast is the only place we use the DSCP on Kerio.

How has it helped my organization?

Now that we're both running fiber connections between Sydney and Adelaide, I can access our document server in Adelaide just from my PC, rather than using something like TeamViewer and transferring the file I'm after via TeamViewer from Adelaide. I get to it not much slower than the internal server we have right now. It's fantastic.

What is most valuable?

The routing of the multiple Internet physical routers I have is the most valuable feature of this solution. Instead of me physically unplugging a cable from one router to the server, if one connection goes down, it automatically switches for me. So I can have all three of them plugged in. If one goes down, it just picks up the other one automatically. There's no physical cable swapping.

In terms of ease of use, it's pretty easy. It took some playing around for me to understand some of it, but I'd say if you understand what it is you're after, and how that works, then this is pretty easy.

We use the firewall. It's fine, a bit tough. I need to test it against others. I'd rather use the Kerio firewall than the Windows ones.

With the VPN features we can connect all three of our sites together.

The content filtering and VPN features are pretty easy to set up. It's a couple of clicks and it's done, so it's pretty good. I'm pretty happy with it.

I am the only manager who manages the security. It does save me time. In the scenario where one Internet connection goes down, I used to have to run to the server room and unplug a cable, and come back. Now, I don't have to do that at all. It saves me a lot of time, 100%. With the routing, previous to this there are a few things in here that I haven't had the ability to really do how I wanted so I don't have a comparison.

What needs improvement?

I would like it if the interface section had multiple failovers. Although I do have three connections, just in case our physical cables get disconnected, I can only set up one failover as a backup. So, if for some reason our fiber and our AFM went down together, I would have to have it search for our 4G modem. I'd love to have extra backups running.

Someone set a printer to have a static IP address and because they set it as static, it won't show on my LAN, on the DSCP server, because it's not questioning it. So just because the device does not request the rules from the DSCP, I don't see why it wouldn't show up in my LAN on the DSCP server. That's a bit odd. It's different from how a Windows DSCP server would react. Instead of only showing one is requesting DSCP, or on a reservation, it shows all, whether they're reserved or not. A Windows one would. For some reason, it isn't showing me ones that were statically assigned.

For how long have I used the solution?

I have been using Kerio Control for four to five years. 

It's deployed in three different locations now. 

What do I think about the stability of the solution?

The stability is pretty good. I've only had one issue with it before. It was set to update on its own, and it didn't update and the update failed, so it didn't come back on for some reason.

If an update fails, it should have some kind of automatic rollback to bring itself back on. Because when it does that at night and it stops, I don't really get a notification that it's stopped. It's not on anymore so I don't find out that nothing has worked all evening until the next morning.

What do I think about the scalability of the solution?

Scalability is fantastic. I don't see a limit to it.

I am the only admin for this solution.  

We employ a company that contracts stuff out for me, so they're the people that initially installed this for me at the three sites, but I maintain it. If I have other things I don't know how to do, they'll get in, but it's just me and that other team.

Increasing usage depends on whether the business itself acquires other businesses, and that's really why we've got these three locations. We bought a business in Adelaide, so we set up a similar setup to what we had in Sydney. And this year in February we bought another business down in the South Coast of New South Wales and we've set up a similar thing there as well. So if we buy other businesses and I need some other help with the server running, then yes, I'll probably get another license. But only if that happens.

My business is medium-sized and this solution is perfect for it. 

I have one point of access for multiple portions of what I need for routing. We've got an Internal server that's managed by a different company and it was incredibly easy for that other company to put certain rules in place and then for us to create those rules to and communicate to the outside world was incredibly easy to map. There was just no confusion between the two companies that we're talking about what to map. That was in the initial setup, so that all wasn't done by me. They just communicated to each other very easily. This made it very simple. There was no confusion.

How are customer service and technical support?

I've never contacted technical support because I just call the people that I contract to fix things and if they're not quite sure how to fix something, they'd probably contact GFI. 

Which solution did I use previously and why did I switch?

We used to use a Cisco router. That was it. There was a very limited amount of routing I could really perform.

Kerio Control enables us to add multiple routing. We have lots of different options in the one thing. 

Kerio was recommended to me by ITIS. They told me that this one was what they highly recommended we use for what I needed.

What about the implementation team?

The outsourced contractor that we used for the setup was great. There's nothing wrong. I've been using him for a while.

What was our ROI?

I can't imagine not using it. I think if I had to use the Microsoft server to do all of this I'd be very frustrated.

What's my experience with pricing, setup cost, and licensing?

I don't have other ones to compare the pricing to. I haven't used other solutions to know all the features they have. The price seems reasonable to me for something that does so much and works so well.

What other advice do I have?

Kerio Control has not increased the number of VPN clients but we have added clients only because they needed it, not because Kerio is there.

To the best of my knowledge, before Kerio we did not experience a security breach. The only semi security issue we had was that someone had run a virus that encrypted a whole bunch of files on the server. But that was before my time. I was not the IT manager at that point.

If I didn't have the help from someone else that completely understood all of the services that are features of this product, then I probably wouldn't have put it in myself. It's definitely more advanced for people that are handling this type of networking day to day, which I don't. The only other thing that I've had a problem with is Apple servers for some reason, because Apple services come through on so many different servers themselves, and different destinations on the Internet, there's always some kind of issue with updating them on the network with Kerio running. I don't know why. It's just Apple. Everything else is fine.

Personally, I've just learned how to route traffic over a network well. It's helped me to route different parts of the Internet to different parts of my network, which I can't do on a Window server, and visually it's been a great help.

It's been able to add multiple Interfaces, it's good. I have multiple Internet streams and a failover. That's the best.

I would rate it a nine out of ten.

Scales easily, works well, and has good content filtering options
Pros and Cons
  • "The firewall and the content filtering options are valuable."
  • "There isn't a lot to be improved. It works well as it is, but they can maybe improve the reporting side."

What is our primary use case?

We use it for our data plan. We are using its latest version.

What is most valuable?

The firewall and the content filtering options are valuable.

What needs improvement?

There isn't a lot to be improved. It works well as it is, but they can maybe improve the reporting side.

For how long have I used the solution?

We have been using this solution for about five years.

What do I think about the stability of the solution?

It is pretty stable. We don't have any issues.

What do I think about the scalability of the solution?

It scales easily without a challenge. We have about 400 users, but administrators directly work with it.

How was the initial setup?

It was pretty straightforward. It took about an hour.

What about the implementation team?

We deployed it ourselves.

What's my experience with pricing, setup cost, and licensing?

Its licensing is yearly. You renew every year. Its price is all-inclusive.

What other advice do I have?

It works well. I don't have a problem with how it works. I am also fine with its deployment, but it can be challenging if you don't have someone skilled or trained. If you have the skills, its deployment would be straightforward. You would be able to deploy it without a challenge. So, you just need to find the right person to deploy it.

I would rate it an eight out of 10.

Effective ISP feature, stable, and simple deployment
Pros and Cons
  • "The most valuable features of Kerio Control are the IPS and traffic rules. The traffic rules are very user-friendly and the IPS is working well. Additionally, the anti-virus is effective with quick options, such as filtering."
  • "Kerio Control could improve by having higher availability and adding a mobile VPN channel. These additions are needed. The VPN is working fine on the Kerio Control but there needs to be a VPN client on the mobile phones, both for iOS and Android. This would be very good for us."

What is our primary use case?

We are working with VMware and we are using virtual machines for Kerio Control.

What is most valuable?

The most valuable features of Kerio Control are the IPS and traffic rules. The traffic rules are very user-friendly and the IPS is working well. Additionally, the anti-virus is effective with quick options, such as filtering.

What needs improvement?

Kerio Control could improve by having higher availability and adding a mobile VPN channel. These additions are needed. The VPN is working fine on the Kerio Control but there needs to be a VPN client on the mobile phones, both for iOS and Android. This would be very good for us.

In a future release, SD-WAN features would be very useful.

For how long have I used the solution?

I have been using Kerio Control for approximately seven years.

What do I think about the stability of the solution?

The solution is stable. However, we have had some problems, and we want to receive some updates for the IPS module. Sometimes we have errors downloading the IPS updates.

How are customer service and support?

I have not contacted technical support. When I have an issue I search the internet and solve the problem. When I search Google, I find solutions for my problem.

Which solution did I use previously and why did I switch?

Previously I was using OPNsense and pfSense. However, Kerio Control is more user-friendly and stable than pfSense and OPNsense.

How was the initial setup?

The deployment of Kerio Control was easy and user-friendly. We have no problems deploying the Kerio Control, Kerio Portal, and Kerio Connect for our customers.

What's my experience with pricing, setup cost, and licensing?

I am living in Iran and we cannot buy the product from Kerio because of sanctions.

What other advice do I have?

I rate Kerio Control an eight out of ten.

Disclosure: My company does not have a business relationship with this vendor other than being a customer.
