A stable solution with an intuitive interface and quick customer service

I have been working with Fortinet FortiGate, WatchGuard, Sophos, and SonicWall. I'm not as comfortable with SonicWall because of their UI and limitations. I prefer Fortinet above all other options. When it comes to configuration, I am confident in my ability to handle various tasks, including creating policies such as firewall rules, web policies, and application policies. Additionally, I can configure VPNs and implement load balancing, among other tasks. Overall, I feel much more comfortable working with Fortinet. Fortinet has made significant improvements by integrating AI with firewalls for threat analysis and prevention. In the past 2-3 years, they have launched FortiSASE and SIEM, and they also provide SOC services. Both Palo Alto and Fortinet FortiGate are excellent. While Fortinet FortiGate comes at higher prices, the functionality and support justify the cost. They promptly resolve firmware issues and inform all support providers about configuration changes.

pfSense flexibility overall is pretty good. They are making some really big improvements. That said, they're a long way from enterprise. They advertise things that they don't have. I've worked for probably 30% of the Corporate 100, and they won't tolerate the high availability and it being as buggy as it is. The fact that if you configure it incorrectly without any visual indications that it's not done in the way Netscape does, then it will not only break the firewall, it will break both firewalls. The only way you can even try to recover is by getting new images from Netgate. You have to open up a tech support case, download the image for, then reimage the firewalls, and reapply your configuration. The fact that you can completely brick your firewalls just by having a configuration that they allow, and they don't even don't tell you there's a problem until they both go down. That's totally unacceptable in an enterprise. As a standalone firewall, they're excellent. As an enterprise, we're not touching it with a ten-foot pole. It’s difficult to configure and use add-on features. It's really easy to add them. On the website, they say “Oh, we do this, this, and this.” However, they do a lot through third-party add-ons. The problem is, if there's any problems at all, the very first thing they want you to do is disable those add-ons. So that's not really supporting anything. There are two ways that firewalls are viewed: talking to the firewall and talking through the firewall. If you're talking about “to the firewall,” then it's a very robust, very secure firewall. However, it doesn't have things that they claim helps with protecting data, most of it's third party. If you want to do all these things that are typically associated with enterprise-level firewalls, most of them are done by a third party. It's not actually cooked into their product. I like their OSPF. I wish it was more current. The only bugs that are in the OSPF are ones that have been known about for almost two years. Maybe they're they're victims of their own success. Their growth curve has outstripped their technical support and has outstripped their ability to develop. They're just growing so fast. They're trying to do everything. Updates from third parties can take too long. For example, if there's a problem with a package and no available update is available, you have to wait. Since it's via a third party, there's no definable schedule, as the update needs to come from a third-party open organization with no financial interest to make the process faster. Sometimes, there's more finger-pointing than resolution. In, OSPF, they give you lots of information. However, when it comes to hardcore troubleshooting of different routing zones or things like that, then you had to keep dropping down to the CLI in order to get it. And that's where your experience can change quite a bit. If you're running OSPF on Cumulus or some of the other big routing or switching solutions, then they're running much newer versions of it, which are all bug-patched and fixed. However, pfSense is running on an operating system that is not theirs. They don't necessarily have full control over it. When you get a real enterprise firewall, and when you hook up the redundancy, you expect redundancy to work and be predictable. And never ever will the redundancy crash your system. If you don't create the interfaces in the exact same order on both firewalls every single time, if so much as one interface is out of order, if the command line is different because of the way the operating system works, you will slowly corrupt your configuration to the point where it'll break.

User has benefited from stable performance and effective completion of security tasks

I use it mostly for VPN and for some firewall solutions When considering my main use case with VPN, I can say that I got the Zyxel Unified Security Gateway, and it works fine. However, we are thinking about using a different solution based on open source because Zyxel Unified Security Gateway…

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"The most valuable feature is the interface, which is very user friendly. We are utilizing most of the features, like content filtering. The firewall is powerful."

"The tool's most valuable feature is IPS. In my experience, I haven't encountered any issues with integration. It easily integrates with the FortiGate solution. However, verifying through documentation and assessing their support is necessary."

"The most valuable features of Fortinet FortiGate are the different types of profiling. It has been the most effective for me. The WAF and the antivirus profile are the most effective in network protection."

"Regionally, we are well covered. Technical support is good in this area."

"We use the filtering feature the most. It has filtering and inbuilt securities. We can create customized rules to define which users can access a particular type of site. We can create policies inside the firewall."

"It's a flexible solution."

"It performs very well."

"The initial setup is easy."

More Fortinet FortiGate pros

"I handle the scanning for the finance department. I recently encountered an issue with the PCL bills, our company bills. I resolved the matter, cleared the bill, and received calls regarding it using pfsense.The user interface is extremely user-friendly, which is why we use it across various plant sites. Our IT representatives at the plants find it easy to use and manage because of its straightforward interface."

"Netgate pfSense has positively impacted my organization because when we look at other firewalls or alternatives, they are costly."

"The most valuable aspects of pfSense are the stability, hardware compatibility, and low cost."

"It is easy to use and has integrity with other systems, such as proxies and quality of service."

"The flexibility is very good; we have a lot of possibilities."

"I would rate pfSense a nine out of ten."

"I like that there's a community edition that I can install on my own virtual machines or hardware. I can test things without messing with them in production, which is incredibly useful. If you have a Juniper or Cisco, you can typically only afford one. You're forced to make changes in production and hope they don't break anything because there's no easy way to have a testing environment. The free version of pfSense offers load balancing or failover WAN, which is also helpful. Most commercial firewalls don't have that in the cheapest iteration of the hardware."

"Deploying pfSense is easy. I'm not a network administrator, but I'm familiar with computers. I can install it on a USB and set it up like any other operating system. The documentation is excellent. I can configure it based on that, and many YouTubers cover it."

More Netgate pfSense pros

"This is a capable appliance and the standard features work well for us."

"The Zyxel Unified Security Gateway solution is stable and does its job effectively."

"The solution can scale well."

"The most valuable features of the solution stem from web filtering, malware protection, and antivirus."

Cons

"We would like to see an upgrade to the VPN feature, we are using the VPN from outside of our office and there is a limitation to 10 connections, more connections would be suitable."

"Usually, we sell the bundle with the UTM or threat management piece with IPS, IDS. Other providers, such as Palo Alto, are ahead in terms of safe functionality. So, for me, delivering truly safe service is probably something that still needs to be improved."

"I would like to be able to generate reports about the protections that we have. I would like a report feature."

"One point against them is that their solution lacks a unified approach."

"The stability of Fortinet FortiGate could improve."

"Its performance can be better. We have had performance issues in the past, but we sometimes tend to find that it is more related to what we do in our network than anything else. It is quite a good product, and there isn't much to improve."

"FortiGate Next Generation Firewall's performance and threat intelligence could be improved."

"The captive portal could be improved."

More Fortinet FortiGate cons

"For the third-party packages, I'd rather have it built-in, like a core feature of pfSense, part of the core model."

"Needs services on additional features, such as managing inventory and generating reports."

"We have to be connected to the internet to download the OS in real time, which, in some cases, is not possible."

"It needs to be more secure."

"The solution’s interface must be improved."

"One or two of the plugins didn't do what I wanted them to do. Maybe that was a misunderstanding or it's not quite ready yet. Sometimes, it's hard to wrap my head around the way the firewall rules work."

"They can improve the dynamic of the input of IPs from outside."

"We are at the moment looking to use it as a proxy service so that we can limit what websites people go and view and that sort of thing. That's an area I've struggled with a little bit at the moment and it could be a bit easier to set up."

More Netgate pfSense cons

"Sometimes it reboots when you least expect it, and that's the main issue."

"The product has some scalability and data management issues where improvements are required."

"Although manageable, the user interface is a little bit slow and could be improved."

Pricing and Cost Advice

"Before choosing a piece of equipment you have to take into account the cost-benefit offered by each one. Sometimes it is not worth paying a very cheap price to have a minimum level of security."

"The price is high compared to some of the other solutions."

"It is less expensive than a Cisco solution."

"When comparing the price of Fortinet FortiGate SWG to other solutions it is expensive. The price could be better."

"Its price is affordable and lesser than Cisco. Cisco is expensive. In terms of licensing, there is only one issue. If a customer's license has expired a month ago and they do the renewal after one month, Fortinet renews the license from the start of the previous month. The activation of the product is done from the previous month, not from the date of renewal. The customers usually shout and complain that because they are paying today, the renewal should start from today. The support contract renewals or licensing should be renewed from the date of renewal, but Fortinet starts from the day it had expired. It is a loss for customers. They might have had some problems because of which they did not take the license one month before. Fortinet should work on this. Cisco doesn't do this. Cisco always starts from the day they apply for the license."

"We saved a bundle by not needing all the past appliances from an NGFW."

"Fortinet FortiGate SWG is an affordable solution."

"Although the solution's pricing is high, compared with other products, it may be cheap."

More Fortinet FortiGate pricing and cost advice

"From Sonic Wall, their price is much higher, because for every feature that you want to add, you have to pay. I can do the same things with pfSense, but everything is included in one price."

"It's highly cost-effective for both the average consumer and business users."

"The pricing is reasonable."

"Looking at what it does, I think that it is fairly priced."

"Netgate pfSense is competitively priced."

"There are a few features not included, and when you have to use those features, you have to pay for them."

"pfSense pricing is reasonable."

"This solution provides enterprise-level features at a fraction of the cost of an enterprise firewall."

More Netgate pfSense pricing and cost advice

"The price of Zyxel Unified Security Gateway is good compared to other similar products in the market."

"This gateway is pretty cheap."
