It is my main firewall into the data center and VPNs for clients. It sets up my DMZ and does a whole bunch of other stuff. I am using the latest version.

A rock-solid, customizable, and free open-source firewall with useful intrusion detection, clustering, and HA features
Pros and Cons
- "The intrusion detection feature is the most valuable. It is an open-source firewall, so there is a lot of material on it. I also find the open VPN capability very nice. It is pretty customizable. The clustering and the high availability are the two biggest things to be able to get out of a firewall."
- "Their support could be better in terms of the response time."
What is our primary use case?
How has it helped my organization?
We wouldn't be able to function without it.

881,757 professionals have used our research since 2012.
What do I think about the stability of the solution?
It has been pretty rock solid.
What do I think about the scalability of the solution?
Its scalability is good. I have got web users and other kinds of users, so there can be five or thousands of users.
How are customer service and support?
I paid for some support with them, and it was pretty good. They just could be a little quicker in responding. They have custom level support, so if you got something complicated, they get you up to the upper tiers, but it takes a little bit longer to do that. Once you get there, the support is good. I would rate them an eight out of ten.
Which solution did I use previously and why did I switch?
I used Fortinet previously, and I used Ubiquiti prior to that. We switched partly because of the cost. It also gave me the ability to do the clustering. I can still maintain my VPNs, connections, and other things. I can take down one of the firewalls for maintenance and bring up the other one and not take down my whole user base.
How was the initial setup?
It was not complex. I was able to do it myself, but we had some problems with some of the protocols, and we had to get one of their coders to get in and look at it. Because of that, it was a little complicated to do the high availability stuff.
What about the implementation team?
I did it myself.
What's my experience with pricing, setup cost, and licensing?
I spent a couple of $1,000 on hardware, and the OS was free. A comparable firewall would cost me probably 20 grand. It saved a lot of money.
What other advice do I have?
I would advise others to go for it. I would recommend this solution. It is a good solution. No other solution can beat the price.
There is so much stuff you can do with it. There are so many features, and I have not even scratched the surface on all of them. If it is something that someone doesn't feel like configuring, you can buy a prebuilt system from them and get support.
I would rate pfSense a nine out of ten because of the cost and flexibility. It has been pretty good.
Which deployment model are you using for this solution?
On-premises

Stable, scalable with great extensibility
Pros and Cons
- "Great extensibility of the platform."
- "User interface is a little clumsy."
What is our primary use case?
We mainly use pfSense at client locations where the client is looking for a free alternative for paid/subscription based Network gateway with enterprise grade features
How has it helped my organization?
Being free and open source, we replaced our network gateway with it. Works well on an old Pentium 4 PC with 1 GB of memory. Failover, URL Filtering, Proxy server, traffic monitoring features inbuilt with SNORT IDS/IPS is all we use and have never faced any problem for over 5 years now.
What is most valuable?
The most valuable feature for our company has been the extensibility of the platform which is great. It's a great solution and I have regularly been supplying it to my clients.
What needs improvement?
The user interface could be improved, it's a bit clumsy and clunky.
For how long have I used the solution?
I've been using this solution for more than seven years.
What do I think about the stability of the solution?
This solution is absolutely stable. With some systems there's a necessity to regularly redo the configurations inside the system. With Pfsense that's not the case. I have no issues with it at all.
What do I think about the scalability of the solution?
The solution is very scalable. It has a failover feature so it's highly skilled.
How are customer service and technical support?
Given that the solution is a free and open source product, it doesn't have any technical support center. We just have the online documentation which is not one of the best, but it's good.
Which solution did I use previously and why did I switch?
I previously used a solution from Cyberoam but we had issues with the licensing. That's the reason we mainly stick to Pfsense open source.
How was the initial setup?
The initial setup is a little complex, of intermediate difficulty. It takes about a day.
In terms of deployment, the entire system has been installed and configured to basically take care of a network of roughly around 35 to 40 computers. We have a dedicated physical machine which has been configured and installed throughout.
What other advice do I have?
My only comment would be to suggest that if you wish to implement the solution read the documentation very carefully.
I would rate this solution a nine out of 10.

IT Support Specialist with 51-200 employees
Very stable, relatively easy to set up, and offers good technical support
Pros and Cons
- "The built-in open VPN and the VPN Client Export are the solution's most valuable aspects."
- "There's a bit of a learning curve during the initial implementation."
What is our primary use case?
We just use the solution as a straight-up firewall. There is no VPN access or anything like that. We just use it as a straight-up firewall and we run Suricata on it as a defense.
What is most valuable?
The built-in open VPN and the VPN Client Export are the solution's most valuable aspects.
What needs improvement?
I cannot recall any features that are lacking.
There's a bit of a learning curve during the initial implementation.
You do have to pay extra for better customer service.
For how long have I used the solution?
We've been using the solution for about six months. It hasn't been too long.
What do I think about the stability of the solution?
The solution is very stable. We've had zero issues. There aren't bugs or glitches. It doesn't crash or freeze. It's been reliable.
What do I think about the scalability of the solution?
I have not tried scaling, therefore, I can't really comment on how easy or hard it would be to expand the service.
There's only one person in the organization using the solution, and that's me.
How are customer service and technical support?
The tech support is excellent if you have a support subscription. If you didn't have that, you could be lining up for a while. It could be a hit or miss, whether you get someone that's actually going to help you.
However, we have a subscription and therefore our support is always excellent. We're quite satisfied with the level of service we're getting.
Which solution did I use previously and why did I switch?
Previously, we used Dell SonicWall. There was just a high cost of licensing all the time, and, with having someone go in and troubleshoot for issues as well, it just wasn't cost-effective anymore. pfSense is simply a better solution.
How was the initial setup?
The initial setup has a bit of a learning curve. It's not complex per se. It just takes some getting used to. After the initial deployment, the other six or seven were easy. I could just copy the configuration of the other ones, change some IP addresses, and I was basically done.
What's my experience with pricing, setup cost, and licensing?
There aren't monthly or yearly licensing costs.
What other advice do I have?
We're just cusomers. We don't have a business relationship with pfSense.
We're using the latest stable version of the solution.
I would 100% recommend the solution to others. On a scale from one to ten, I'd give it a ten.
Which deployment model are you using for this solution?
On-premises

Open source, easy to deploy, and works really well
Pros and Cons
- "One of the advantages of pfSense is that it is very easy to work with. It is a very good open-source solution, and it works really well. pfSense provides a complete package. For some features, it could be the first solution in the world. It is a very good alternative in the market for a firewall solution. You don't need to go to Cisco or other brands with expensive firewalls. pfSense also allows us to offer some support services."
- "There is more demand for UTMs than a simple firewall. pfSense should support real-time features for handling the latest viruses and threats. It should support real-time checks and real-time status of threats. Some other vendors, such as Fortinet, already offer this type of capability. Such capability will be good for bringing pfSense at the same level as other solutions."
What is our primary use case?
Our main business is for WiFi networks. Customers also ask us for simple firewalls, and we use pfSense to add a firewall to provide the complete solution. We are working with the latest version of pfSense.
What is most valuable?
One of the advantages of pfSense is that it is very easy to work with. It is a very good open-source solution, and it works really well.

For how long have I used the solution?
I have been using pfSense for about four or five months.
What do I think about the stability of the solution?
It is stable.
What do I think about the scalability of the solution?
It is easily scalable. It is more of a hardware thing than a software thing.
How was the initial setup?
It is easy to deploy. Our real deployments are for WiFi networks, and then we add one or two firewalls to protect the network. For a small network, it can take one week. For a more complex network, it could be two or three months. We have a few upcoming projects which would require severe thousand firewalls, and it would take us more than a year.
What's my experience with pricing, setup cost, and licensing?
It is open source.
What other advice do I have?
I would recommend pfSense, but it depends on the requirements. There could be other vendors who offer more services than pfSense. For example, Fortinet is a very good brand, and it offers services in a different way. Fortinet also offers more services, but it is very expensive. If you don't need some specific services, pfSense is an excellent solution.
I would rate pfSense a nine out of ten.

Offers a nice interface and good technical support and has a nice load balancer
Pros and Cons
- "It's a good solution for end-users. It's pretty easy to work with."
- "The solution could use better reporting. They need to offer more of it in general. Right now, the graphics aren't the best. If you need to provide a report to a manager, for example, it doesn't look great. They need to make it easier to understand and give users the ability to customize them."
What is our primary use case?
Typically, we implement this solution on an enterprise-level for our clients and set it up for them as required.
What is most valuable?
The solution offers good value.
The captive portal on the product is excellent.
The solution has a very nice load balancer.
It's a good solution for end-users. It's pretty easy to work with.
The user interface is very nice. It's easy to navigate around the solution.
Technical support is very helpful.
What needs improvement?
The solution could use better reporting. They need to offer more of it in general. Right now, the graphics aren't the best. If you need to provide a report to a manager, for example, it doesn't look great. They need to make it easier to understand and give users the ability to customize them.
For how long have I used the solution?
I've been working with the solution for enterprise-level organizations for four or five years at this point.
What do I think about the scalability of the solution?
Our clients use the solution across 100-200 computers. Some of the implementations are sizeable.
How are customer service and technical support?
I've dealt with technical support in the past and have found them to be helpful and responsive. we have been satisfied so far with the level of support provided. They are easy to work with.
How was the initial setup?
We implement the solution for our clients, so we have a good sense of what is expected.
What about the implementation team?
As an implementer, our company can handle the initial setup for our clients.
What other advice do I have?
We implement the solution for our clients. I've personally implemented the solution on five projects so far.
We work with the latest version of the solution, typically.
Our companies are typically mid-level enterprises.
This product is the very best. Overall, I would give it a rating of ten out of ten.

Senior System Engineer at a financial services firm with 1,001-5,000 employees
Open-source, stable, and supports at least 5,000 concurrent connections
Pros and Cons
- "At our peak time, we have reached more than 5,000 concurrent connections."
- "It needs to be more secure."
What is our primary use case?
We have internet limitations here in Sudan. The financial institutions that I am working with do not have a lot of services on the internet.
It is difficult but at the same time, we are safer and are not faced with any kind of compromised data.
This solution is suitable for small businesses and charity organizations. Security is not just about the firewall, you need policies and procedures in place.
What is most valuable?
The developers of pfSense follow the principles of open-source.
They keep it simple. It's simple and good.
What needs improvement?
The problem with open-source is that no one can take responsibility.
It needs to be more secure. Security needs improvement.
It's always better to have an agreement, an SLA regarding security. You should outsource your security to another company.
For how long have I used the solution?
I have been using pfSense in my home environment since 2010. I have a small lab, a small environment.
We have also deployed it in my workplace.
What do I think about the stability of the solution?
It's a stable solution.
What do I think about the scalability of the solution?
pfSense is scalable.
At our peak time, we have reached more than 5,000 concurrent connections.
How are customer service and technical support?
I do not have experience with technical support.
Which solution did I use previously and why did I switch?
I am also using IPFire. It's also open-source.
It's very stable, and it meets my business needs.
How was the initial setup?
The initial setup is straightforward.
If you have solid knowledge and experience in IP tables, then it will be easy for you to deal with this product or any firewall. For example, Palo Alto or Fortinet. It's the same concept.
Depending on your activities, it can take a long time to deploy if you are new to this solution. For me, it takes less than one hour.
You have to understand the network technology and you have to understand what you are going to protect, and what service are you looking to protect. If you address these questions correctly, the installation is just a matter of a couple of clicks.
What about the implementation team?
I completed the implementation myself.
What's my experience with pricing, setup cost, and licensing?
We are using the open-source version, not the commercial one.
It's very affordable.
What other advice do I have?
I would continue to use pfSense if the decision was mine, but it is out of my area. It depends on the CIO.
I would recommend this solution to others who are interested in using it.
pfSense will not cost you any money.
It depends on your business needs. You have to address your business needs correctly.
I would say to go with pfSense. If you feel that it is not compatible, you have other purchase options such as Palo Alto.
I would rate this solution a ten out of ten.
Which deployment model are you using for this solution?
On-premises

Great pricing, good documentation, and offers very good integration capabilities
Pros and Cons
- "The documentation is very good."
- "The technical support needs to be improved."
What is our primary use case?
I use the product for many enterprise clients, including building construction, government, and education.
What is most valuable?
The documentation is very good.
The pricing is okay. It's not too expensive.
The integration capabilities are great. The product can integrate well with Check Point and Fortinet. They make it a very easy process.
It's very good at defending our company.
What needs improvement?
It would be ideal if the solution could integrate with Snort and OpenVPN.
The technical support needs to be improved.
For how long have I used the solution?
I've been using the solution for ten years at this point.
How are customer service and technical support?
The technical support is not great. It's very slow. Sometimes it will take four days in order to connect with them, which is actually a decent timeframe for them.
Their documentation, however, is pretty good.
How was the initial setup?
The initial setup is not complex. It's pretty straightforward. The onboarding process is pretty good. They make everything very, very easy. People shouldn't have any issues with implementation.
What's my experience with pricing, setup cost, and licensing?
We've found the pricing to be very fair. It's actually pretty low. The licensing is very inexpensive.
Which other solutions did I evaluate?
We looked at Fortinet and CheckPoint in relation to how they work with Linux.
In the case of Fortinet, the content filter is a URL content filter. It's very different and it's complex to use.
What other advice do I have?
We're a pfSense partner.
I'd rate the solution ten out of ten. It's been very good to work with.
I would recommend the solution. pfSense is superior in terms of defending against attacks.

Cost effective, with an easy setup, but not suitable security at the gateway level
Pros and Cons
- "The initial setup is easy."
- "As an open-source solution, there are so many loopholes happening within the product. By design, no one is taking ownership of it, and that is worrisome to me."
What is our primary use case?
We primarily use the solution basically for the firewall, UTM content versioning, bandwidth shaping, routing, and IPS.
What is most valuable?
The solution is an open-source product, which makes it very cost-effective.
Overall, it covers all of the requirements our organization has at this time.
The initial setup is easy.
What needs improvement?
As an open-source solution, there are so many loopholes happening within the product. By design, no one is taking ownership of it, and that is worrisome to me.
Integration with other products could be improved. It needs log research integrated within it to make it more useful for our purposes.
For how long have I used the solution?
I've been using the solution for three years.
What do I think about the stability of the solution?
The stability is questionable. There are glitches. Since no one is really managing the solution, and no one takes ownership of it, there aren't many fixes that happen on it.
What do I think about the scalability of the solution?
We have about 500 people who are taking advantage of the solution within our organization.
The solution is quite scalable. We looked into scaling and found it would be easy enough to achieve if we decided to go ahead and do so in the future.
How are customer service and technical support?
We've never contacted technical support int he time that we have used the product. I can't speak to any level or service they provide.
Which solution did I use previously and why did I switch?
We did previously use a different solution before switching to pfSense. We originally switched to this solution due to the fact that it was so cost-effective.
How was the initial setup?
The initial setup of the solution is not complex at all. It's quite straightforward. It's also not our primary firewall. We have another solution for that. This operates as our secondary firewall, and we were able to add it rather easily into our security network.
Deployment is very quick. It only took us an hour or so to set up.
Our provider handled the maintenance for us as needed. We don't handle that in house.
What about the implementation team?
We had a few consultants and a list of vendors that assisted us in the process of procurement and implementation.
What's my experience with pricing, setup cost, and licensing?
The solution is open-source and therefore the solution is very cost-effective.
What other advice do I have?
We're just using this solution; we don't have a relationship with the vendor.
In terms of the version of pfSense we are using, we have that basic boss, 1.0 however, that is behind the firewall. The firewall which we were using is UTM1240B.
While we are satisfied with the netting features and the bandwidth controlling and routing, we find cannot expose our entire network to pfSense as there's no underlying ownership fo the product itself. We prefer a hardened firewall.
Due to the fact that it is an open-source solution, no one at an enterprise-level would ever think of putting pfSense at the gateway level or even at the main level. I would definitely recommend pfSense as the second lane of action, just not on a workload.
I'd rate the solution six out of ten.
Which deployment model are you using for this solution?
