A firewall or router computer software distribution solution with a useful VPN feature
Pros and Cons
- "I especially like the VPN part. It works like a charm."
- "I tried pfSense, and it has a big issue with file system consistency, and this is what drove me to OPNsense. The file system stability is quite a big issue for us. We have a lot of outages related to power issues, and OPNsense is much more stable on this side."

What is most valuable?
I especially like the VPN part. It works like a charm.
What needs improvement?
I tried pfSense, and it has a big issue with file system consistency, and this is what drove me to OPNsense. The file system stability is quite a big issue for us. We have a lot of outages related to power issues, and OPNsense is much more stable on this side.
I would like it to be more stable on the file system part. It also has an issue with the ARP publishing, but it's common to BSD, and some providers experience issues with Layer 2 connectivity.
For how long have I used the solution?
I tested pfSense for six months, but it had quite a lot of networking issues related to latency and ARP publishing. So, I immediately switched to OPNsense.

857,028 professionals have used our research since 2012.
What do I think about the stability of the solution?
I'd like to see its stability improved. I know the BSD Kernel is more capable than what pfSense provides at this time.
What do I think about the scalability of the solution?
It's scalable. It implements specific protocols for scalability.
How was the initial setup?
The initial setup is straightforward. It took me about ten to 15 minutes to install it and maybe half an hour for configuration.
What about the implementation team?
I implemented this solution.
What other advice do I have?
I would recommend this solution if there are no power issues. It's stable and performs well, even on older hardware.
On a scale from one to ten, I would give pfSense a nine.
Which deployment model are you using for this solution?
On-premises

CEO at a tech services company with 1-10 employees
A free firewall and router that is entirely managed via web interface
Pros and Cons
- "The VPN is my favorite feature."
- "The main problem with pfSense is that we have to use proxy solutions."
What is our primary use case?
We have solutions from 10 to 5,000 users. One person alone can manage the firewall.
What is most valuable?
The VPN is my favorite feature. pfSense is very easy to use. The interface and configuration capabilities are great.
What needs improvement?
The main problem with pfSense is that we have to use proxy solutions. They don't have features like Layer 7 filtration. We can't filter based on applications. For this reason, we need to work with solutions from Cisco like OpenAPPID that help pfSense understand similar applications. For example, if I have to block WhatsApp, I need to use a third-party solution like OpenAPPID to help it understand what WhatsApp is. This capability is not native to pfSense, so I have to use another solution, like an add-on. I think that the proxy is the main problem with pfSense.
pfSense doesn't implement SD-WAN solutions. Competitors have this feature. If pfSense began doing this, it would be a big improvement.
What do I think about the stability of the solution?
Stability is great. That's a strong point.
What do I think about the scalability of the solution?
Scalability-wise, it's great. Often, we need to research and assess the size of an appliance in order to understand what kind of environment the firewall is going to protect. From here, we have the possibility to do an upgrade depending on the type of model.
There is the option to have a firewall that is entry-level or a firewall that supports a huge internet service provider. We have many solutions that we can apply to our customer's environments, but first, we need to do these assessments in order to help us choose the right appliance. One appliance simply can't be upgraded to cover this entire spectrum of needs or the size of demand. This is why we must perform these special assessments.
How was the initial setup?
Although it's not quite pre-configured, it is ready to use, straight away. It's so easy to put it to work. We had to do some configurations, mainly related to security issues. Configuring rules for monitoring had to be done, but otherwise, it's ready to go, out of the box.
Only one person is required to deploy this solution.
What's my experience with pricing, setup cost, and licensing?
pfSense is a free solution.
What other advice do I have?
Before deciding to go with this solution, make sure to evaluate the features to ensure that pfSense will cover your needs. pfSense is very strong in some areas, but it has some difficulty in others. It's a good solution, but it all depends on what you expect from the firewall.
If you need the firewall to implement security in your network, then pfSense is better than the competition in terms of price. It will cover all of your basic needs for far less money than similar products that cost five to ten times more money.
Overall, on a scale from one to ten, I would give pfSense a rating of nine.
Which deployment model are you using for this solution?

Flexible with a straightforward setup and great plugins
Pros and Cons
- "The initial setup is straightforward."
- "If you want to take advantage of all of the solution's options, you need to have a bit of a technical background. It's not for a layperson."
What is our primary use case?
We primarily use the solution for security. It's a firewall.
What is most valuable?
The solution is an excellent open-source product. It has a big community around it as well. Out of those few points, you'll come up to a situation whereby you can avoid the vendor lock-in. Since there is a big community, you can count on reliability. There are lots of installations and lots of people who understand how everything works.
The solution offers excellent flexibility. You can either install pfSense just on a machine, on your local PC, or you can buy an appliance. You can even buy your own hardware and install it on your own. Of course, if you choose that route, you need to have a technical expert on your team. For us, as a software company, that's not a problem.
There are plugins you can add to the product if you want even more useability. You can even add more security functionality.
The initial setup is straightforward.
What needs improvement?
We did have a strange issue with an update at one point, however, that was resolved quickly.
If you want to take advantage of all of the solution's options, you need to have a bit of a technical background. It's not for a layperson.
You do get a good solution for free. However, the trade-off is you need to be technical to really take advantage of it.
The installation could potentially be faster.
For how long have I used the solution?
I haven't been using the solution for very long at this point. It may be somewhere around three to five months. It hasn't been long.
What do I think about the stability of the solution?
The solution is very stable. There are no bugs or glitches. It doesn't crash or freeze. It's excellent.
What do I think about the scalability of the solution?
The scalability is excellent. We don't have any issues as far as that is concerned.
Which solution did I use previously and why did I switch?
Prior to pfSense, we used Cisco.
How was the initial setup?
The implementation is not complex. It's very straightforward to initiate. A company should have no problems with the process.
What's my experience with pricing, setup cost, and licensing?
As an open-source solution, it is free to use as you see fit.
Which other solutions did I evaluate?
I didn't evaluate the solution against other more expensive commercial tools.
What other advice do I have?
We are just customers and end-users.
The solution is an open-source platform. We are a software company and we like open-source. Lots of people say open-source means that you need to install it on your own. They will see that as a limitation, however, we see that as the other way around.
I'd recommend the solution to other organizations and users. It's open-source, it's flexible, and has a strong community. You can use it in many different ways, either in a small installation, laptop, PC, or on a machine, or you can buy an appliance or you can even buy your own hardware and configure it in a different way. The software as such is free and you have a lot of options as to how you want to use it.
I'd rate the solution at a ten out of ten. It's been very good for us

Secure protection, superior for small business, and support helpful
Pros and Cons
- "I have found the most valuable features to be antivirus and malware protection."
- "This solution is good for small businesses but it is not as stable as other competitors such as Fortinet."
What is our primary use case?
We use the solution for blocking websites, banking, and malware.
What is most valuable?
I have found the most valuable features to be antivirus and malware protection.
For how long have I used the solution?
I have been using the solution for approximately four months.
What do I think about the stability of the solution?
This solution is good for small businesses but it is not as stable as other competitors such as Fortinet.
What do I think about the scalability of the solution?
We currently have approximately 45 people using the solution.
How are customer service and technical support?
The support is good when comparing to other solutions.
Which solution did I use previously and why did I switch?
We have used FortiGate in the past and they tend to be more stable, but lacking in other areas.
How was the initial setup?
The installation was not too complicated. We did have some issues with the port forwarding, some of the server application were not getting through the firewall but we managed to get it to work.
What about the implementation team?
The whole network deployment took approximately three days.
What's my experience with pricing, setup cost, and licensing?
We are using the open-source version which is free. We are testing the solution to see if we are going to go to the enterprise version which requires a license and is not free.
What other advice do I have?
For those who want to implement this solution I would advise it is great for a small enterprise, it is best to get started without having any harm getting to their networks.
I rate pfSense an eight out of ten.
Which deployment model are you using for this solution?
On-premises

An open source firewall solution with a useful encryption feature
Pros and Cons
- "I like the connectivity to the open VPN. It's very smooth."
- "They can improve the dynamic of the input of IPs from outside."
What is our primary use case?
I was working for a firm that has 70 employees. They are mostly working from home, so I needed a very well-structured VPN for remote working. We put it on Supermicro, and it worked fine, and it was above their needs.
What is most valuable?
I like the connectivity to the open VPN. It's very smooth. All the encryption in the open VPN is very good. The structure of the pfSense software works out very well. The PF work cuts and the snorts and whatever we put on the console for spyware and attack prevention seem to work very nicely.
What needs improvement?
They can improve the dynamic of the input of IPs from outside. Determining the IPs that are outside would be another way to identifying potential threats. We can treat it or identify and then block it or determine the rules to work with that IPs from the outside and inside the network.
For how long have I used the solution?
I have been using pfSense for the past three years.
Which solution did I use previously and why did I switch?
Back in the day, I was using Fortinet, and it was very tricky to get it working without spending more money. pfSense is exactly what we paid for, and it's still working very well. We've been working with it for two or three years, and it's a very good solution, and I didn't have to spend any more money on it.
Cisco VSL and Fortinet are tricky when it comes to improving the firewall rules or creating rules above older rules. In pfSense, it's very logical. It's simple.
How was the initial setup?
The initial setup is very linear and very smooth.
What other advice do I have?
On a scale from one to ten, I would give pfSense a nine.

Free to use with an easy initial setup and good scalability potential
Pros and Cons
- "We've found the stability to be very good overall."
- "The access control aspect of the product could be improved."
What is our primary use case?
We primarily use pfSense as a firewall. It's a DHCP server.
What is most valuable?
The most valuable aspect of the solution is the way it can browse packages on the internet.
The initial setup is very easy.
We've found the stability to be very good overall.
The product can scale if you need it to.
What needs improvement?
The access control aspect of the product could be improved. There should be more control over everything that the user is doing. It should be able to log and report on everything users are doing.
The product no longer complies with new rules in Brazil. Therefore, we need to move off the solution.
For how long have I used the solution?
I have about five years of experience with the solution. It's been a while since we started using it at our organization.
What do I think about the stability of the solution?
The stability of the product is very good. We haven't had any issues. There aren't bugs or glitches. It doesn't crash or freeze. It's reliable.
What do I think about the scalability of the solution?
We've found the solution to have good scalability. If a company needs to expand, it can do so. That shouldn't be a problem.
We have about 10,000 people using the solution. There is a network manager and about ten people that work directly with the solution.
We won't be increasing usage, however. The Brazilian government recently changed some laws and this product is no longer in compliance. That is one of the reasons we are looking at Palo Alto. We are likely moving away from this solution.
How are customer service and technical support?
While the websites and forums are excellent, we don't have any dealings directly with technical support. Therefore, we can't speak to how they are in terms of their responsiveness or knowledgability.
Which solution did I use previously and why did I switch?
A long time ago, the company did use a different solution. They switched to pfSense. However, now they are moving away from it as well.
We're also using Palo Alto, however, right now, it's just in the demo phase. The solution seems to be better at centralization, which is a big selling point. We have three school campuses and we'd like to configure a solution from one central location that would work for all three campuses. With Palo Alto, it looks like we can achieve this.
On top of that, with Palo Alto, there are more user control products. You can log everything that you are doing on the internet with it.
How was the initial setup?
The initial setup of the solution is very easy. It's straightforward. There isn't any complexity. A company shouldn't have any troubles with the setup.
What's my experience with pricing, setup cost, and licensing?
We are using a free version of the solution. We don't need to pay any licensing fees.
What other advice do I have?
We are just customers. We don't have a business relationship with the company.
I would recommend the solution to small companies. If you are a small company, you can use pfSense without any issues due to the fact that it's a free solution.
I would rate the solution seven out of ten.
Which deployment model are you using for this solution?
Public Cloud

An open source firewall solution with a useful Packet Manager feature
Pros and Cons
- "pfSense helped us during COVID-19 because we used OpenVPN to connect from home."
- "The main problem with pfSense is that it lacks adequate ransomware protection."
What is our primary use case?
We use pfSense for the firewall, VPN server, client-server, and internal network.
How has it helped my organization?
pfSense helped us during COVID-19 because we used OpenVPN to connect from home.
What is most valuable?
I like the Package Manager feature.
What needs improvement?
The main problem with pfSense is that it lacks adequate ransomware protection. I would also like pfSense to be more robust like Cisco or Fortinet.
For how long have I used the solution?
I've been using pfSense for two or three years.
What do I think about the stability of the solution?
The stability is very good.
What do I think about the scalability of the solution?
Scalability is very good. We didn't have to slow down, and we worked with it for months.
How are customer service and technical support?
The pfSense page, community support, and YouTube tutorials are good.
How was the initial setup?
The initial set up is complex and took two days to deploy.
What's my experience with pricing, setup cost, and licensing?
pfSense is open-source.
Which other solutions did I evaluate?
I like Fortinet and Sophos as they have more tools to prevent ransomware attacks. Sophos has a client-server, and pfSense doesn't have that. Fortinet and Sophos are under a paid license, and pfSense is open-source and free. This is the main difference.
What other advice do I have?
I would recommend pfSense to potential users. I would tell them to just read the tutorials because they're very useful.
On a scale from one to ten, I would give pfSense a nine.
Which deployment model are you using for this solution?
On-premises

Scalable application integration, offers customization, well priced
Pros and Cons
- "The solution is fairly scalable when it comes to integrating with other applications and data sets."
- "They could improve their commercial stance and be more agile when it comes to the commercial pricing of enterprise deals."
What is most valuable?
The solution is fairly scalable when it comes to integrating with other applications and data sets. They have a lot more customization compared to the competition.
What needs improvement?
They could improve their commercial stance and be more agile when it comes to the commercial pricing of enterprise deals.
For a feature update, they should increase the API integrations into decentralized identity platforms making it stronger.
For how long have I used the solution?
I have been using the solution for two years.
What do I think about the scalability of the solution?
In my experience, this solution is able to increase its scalability.
How are customer service and technical support?
Technical support is very supportive. When we are in contact with them, there is no problem at all.
How was the initial setup?
The setup was straightforward.
What about the implementation team?
When doing deployments of the solution we generally average approximately six to eight weeks.
What's my experience with pricing, setup cost, and licensing?
The pricing is lower than some of its competitors. However, If you do not have a strong technical team and are trying to get pfSense to do some of the same functions as some of the competitors such as Fortinet or Palo Alto, It will cost you a lot in professional services to do it. You then lose the low cost-benefit of this solution.
Which other solutions did I evaluate?
I have evaluated Fortinet, their pricing is reasonable for the SME market, but they are not enterprise players. The strongest solutions in this field are certainly SentinelOne and Carbon Black, they outperform everything else.
What other advice do I have?
I would recommend the solution to others.
I rate pfSense an eight out of ten.
