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.
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?
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.

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.

The internet is always available and has low balances
Pros and Cons
- "It has a good web cache. I used to use a DHCP server and DNS server. For my company, I use pfSense as a load balancing application."
- "Many people have problems setting up the web cache for the web system."
What is our primary use case?
I use pfSense for the security of my company.
How has it helped my organization?
With pfSense we have low balances for the internet and the internet is always available. When our service provider fails, it takes communication to another service. The employees always have access to the servers that they need. They always have an abundant flow or they always switch to the lead when the internet fails.
What is most valuable?
It has a good web cache. I used to use a DHCP server and DNS server. For my company, I use pfSense as a load balancing application.
The HA proxy is the main feature that it's used for.
What needs improvement?
Many people have problems setting up the web cache for the web system.
They should put an anti-spam in a web application firewall.
For how long have I used the solution?
I have been using pfSense since 2006.
What do I think about the stability of the solution?
The stability is rock-solid.
What do I think about the scalability of the solution?
I think scalability is good enough.
I do the maintenance for pfSense.
How are customer service and technical support?
There is a lot of information in the online forums.
Which solution did I use previously and why did I switch?
I have used other solutions but I chose pfSense because it's easy to use and configure.
How was the initial setup?
The initial setup was very easy.
Before I set up, I wrote down all the levels on a paper and I drew the plan I wanted to protect. After that, I deployed it pfSense. I filtered the access to the users and to the servers. Everyone has the access that they need.
The deployment took less than an hour.
What's my experience with pricing, setup cost, and licensing?
It's open-source. You can pay for support if you need.
What other advice do I have?
I would rate pfSense a nine out of ten.
Which deployment model are you using for this solution?

A great solution that just works and is fast and affordable
Pros and Cons
- "It works. I put pfSense in, and it works. I can't think of any trouble I ever had with it. It runs on heat-sensitive appliances. They don't need a fan, so they don't overheat. It is affordable, fast, and very high-speed. It is built on BSD Unix, and it pretty much runs on any Intel processor."
- "I've never tried it in large environments. All my clients are small businesses with a handful of employees, so I am not sure how it works in large environments. I keep up with recent versions, and there's nothing I'm waiting for, and nothing breaks when I get a new version."
What is our primary use case?
We use it for small businesses, and most of my clients are using pfSense.
What is most valuable?
It works. I put pfSense in, and it works. I can't think of any trouble I ever had with it. It runs on heat-sensitive appliances. They don't need a fan, so they don't overheat.
It is affordable, fast, and very high-speed. It is built on BSD Unix, and it pretty much runs on any Intel processor.
What needs improvement?
I've never tried it in large environments. All my clients are small businesses with a handful of employees, so I am not sure how it works in large environments. I keep up with recent versions, and there's nothing I'm waiting for, and nothing breaks when I get a new version.
For how long have I used the solution?
I have been using this solution for maybe five years.
What do I think about the stability of the solution?
It just works.
What do I think about the scalability of the solution?
I've never challenged it. All of my clients are small businesses. It is open-source software, and it runs on whatever appliance you run it on, so whatever computer you run it on, it'll scale up pretty high.
How are customer service and technical support?
Their technical support is excellent. They do have good support service. I don't use it because I've never had any problems with it, but the people I know who use it in bigger environments love it. You can even search their knowledge base and learn anything you want to know pretty quickly.
Which solution did I use previously and why did I switch?
Some of my businesses just use the built-in firewall in the ISP modem. I replaced an old SonicWall that couldn't keep up with a faster internet service. I've replaced a couple of Cisco solutions that were just getting old to run modern software, but the hardware was working. They just died of old age, and I replaced them with pfSense. It has been great. I'm sure a lot of people know how to configure Cisco solutions, but I don't. pfSense is very easy to configure.
How was the initial setup?
It was very simple. You download and boot a USB stick or a CD to install it. From then on, it is managed by its own webpage. The deployment takes a few minutes.
What's my experience with pricing, setup cost, and licensing?
It has almost zero cost, and it is open to us. It runs on a small appliance just for a couple of 100 bucks, and I've never had an appliance burn out on me yet.
What other advice do I have?
It is just great. Give it a try. It just works.
I would rate pfSense a ten out of ten.
