The gain in performance and security from configuring the VPN connections was significant
Pros and Cons
- "The gain in performance and security from configuring the VPN connections was significant."
- "It is a stable solution."
- "My only observation is about the quality of the IPSec logs, which are difficult to interpret and are poor in filters."
What is our primary use case?
I use pfSense firewall, especially as an IPSec VPN Server. There are several VPN connections with equipment of various manufacturers at the other end.
I use ServerU as hardware instead of an ordinary PC, as most other people usually do.
How has it helped my organization?
The gain in performance and security from configuring the VPN connections was significant, since pfSense has replaced a server with a custom Linux open source version, which was running on outdated hardware.
What is most valuable?
Security and stability. The pfSense server acts as "IPSec VPN Server" for a small financial institution, but regardless of the company size, interruptions would cause significant financial impact.
What needs improvement?
pfSense serves us very well. My only observation is about the quality of the IPSec logs, which are difficult to interpret and are poor in filters. I have more than 10 IPSec VPN connections, and when there is a need for troubleshooting, the logs are of little help.
For how long have I used the solution?
Three to five years.
What do I think about the stability of the solution?
With regard to this configuration, I consider it a stable solution.

Improved service performance and availability through redundancy
Pros and Cons
- "Improved service performance and availability through redundancy."
- "Improve analysis of logs and dashboards (control panel) with improved alert functionality."
What is our primary use case?
Firewall and VPN, Internet link balancing, as the proxy was installed on another machine. Used redundant firewall as a cluster.
How has it helped my organization?
Improved service performance and availability through redundancy. The company already had specialists in Linux, which facilitated the project.
What is most valuable?
Ease of monitoring and placement of other packages and functionalities next to the equipment.
What needs improvement?
Improve analysis of logs and dashboards (control panel) with improved alert functionality.
For how long have I used the solution?
Three to five years.

An incomparable stability is achieved with other firewall systems
Pros and Cons
- "An incomparable stability is achieved with other firewall systems."
- "Firewall system for small, medium, and large data networks. It allows you to provide security to your environment: DMZ networks, LAN, WAN, etc."
- "A very stable product that lasts over time, easy to understand, and administer."
- "It is easy to use and has integrity with other systems, such as proxies and quality of service."
- "It should integrate with LDAP, Active Directory, etc, to improve the way in which the traces and connections of each IP, or user connected through the firewall, are shown."
What is our primary use case?
Firewall system for small, medium, and large data networks. It allows you to provide security to your environment: DMZ networks, LAN, WAN, etc. A very stable product that lasts over time, easy to understand, and administer.
How has it helped my organization?
With pfSense, an incomparable stability is achieved with other firewall systems. It is easy to use and has integrity with other systems, such as proxies and quality of service.
What is most valuable?
Security
- Stability
- Integration with other systems
- Easy assimilation of its features
- Easy administration
- Multiple network management tools
- Load balancing
- Multiple links
- High availability, etc.
What needs improvement?
The connections should be shown in a more specific way, as Kerio Control does. It should integrate with LDAP, Active Directory, etc, to improve the way in which the traces and connections of each IP, or user connected through the firewall, are shown.
For how long have I used the solution?
More than five years.

By installing pfSense and configuring load balancing and limiting bandwidth, we now have a reliable and stable connection.
Pros and Cons
- "Routing, load balancing, Traffic Limiter and queues. Since this company relies on an Internet connection, having these features is a must."
- "Reporting and real-time monitoring, since I'm used to Watchguard's reporting features, it would be nice to have an embedded solution for reporting."
What is our primary use case?
Primary we use it for bandwidth limiting and load balancing our ISPs. And Pfsense excels doing that.
How has it helped my organization?
We had two ISPs, and still our Internet connection was awful. By installing pfSense and configuring load balancing and limiting bandwidth, we now have a reliable and stable connection.
What is most valuable?
Routing, load balancing, Traffic Limiter and queues. Since this company relies on an Internet connection, having these features is a must.
What needs improvement?
Reporting and real-time monitoring, since I'm used to Watchguard's reporting features, it would be nice to have an embedded solution for reporting.
What do I think about the stability of the solution?
Close to none. One time, while upgrading, the system crashed and had to install from scratch. After some research, it was due to an unsupported package that I had installed which the new version didn't like. I just installed and restored my configuration and that was it. No biggy.
What do I think about the scalability of the solution?
Haven't tested this part since the company hasn't grown much.
How are customer service and technical support?
Haven't used the official support channels. The community forum is awesome when you're looking for quick answers.
Which solution did I use previously and why did I switch?
Actually, PfSense replaced a Watchguard firewall, mostly due to costs. But I haven't missed it since.
How was the initial setup?
Very straightforward. For a small company with few configuration options it works almost out-of-the-box. The firewall comes with basic outgoing and incoming rules, and you take it from there.
What about the implementation team?
The implementation was made in-house.
What's my experience with pricing, setup cost, and licensing?
If you need to buy hardware onto which to install PfSense, go with their boxes on their website, they are great. If you already have the hardware, just download and install, it works great either way.
Which other solutions did I evaluate?
I did, I evaluated Untangle, IPCop and MikroTik.
What other advice do I have?
Just go with it, can't go wrong.

I use pfSense because it gives me the flexibility to greatly expand basic firewall features.
Pros and Cons
- "I use pfSense because it gives me the flexibility to greatly expand basic firewall features."
- "The GUI. There are TONS of plugins for pfSense, as such, if a user wants to add quite a bit of functionality, the GUI will feel a little congested."
How has it helped my organization?
I stood up pfSense in a Large Telecom providers Lab environment for their next generation products. I was able to achieve 10G throughput (about 9.1 true throughput as tested over 4 days solid), and only hit a max of 20% CPU utilization on a DL380 G7. This server also had Suricata (in IPS mode and a heavy ruleset), as well as pfBlocker running.
What is most valuable?
I use pfSense because it gives me the flexibility to greatly expand basic firewall features. It's open source (and free - as in beer and speech), but also has commercial support. This can be run on any commodity hardware on the market (I've ran it on AMD and Intel - even Atom, processors) and throughput is excellent, even with lower speed CPUs and less RAM.
What needs improvement?
The GUI. There are TONS of plugins for pfSense, as such, if a user wants to add quite a bit of functionality, the GUI will feel a little congested.
What do I think about the stability of the solution?
A little... BUT, this was contributed to a failing Arista switch that would do a coredump and reboot. The pfSense installation at high speeds failed over perfectly though.
What do I think about the scalability of the solution?
No - in our high-speed tests (10G), we were not able to push the CPU over 20% utilization.
How are customer service and technical support?
I didn't really need any technical support. But was in contact with the Developers of pfSense as we were starting to work with them for an NFV setup.
Which solution did I use previously and why did I switch?
Fortinet, SourceFire, etc.... the cost... oh the cost! Why pay these guys when I can use pfSense for free AND only pay for support when and if I need it?
How was the initial setup?
Very straight forward. If anyone has ever installed any kind of OS or set up a firewall, it will be a piece of cake.
What's my experience with pricing, setup cost, and licensing?
Open Source - just download! If you need support, it's available.
Which other solutions did I evaluate?
What other advice do I have?
It's an amazing product. There really are few issues with pfSense.

The most valuable features are the open VPN capabilities and the firewall service.
What is most valuable?
The most valuable features for me and my current company are the open VPN capabilities and the firewall service.
How has it helped my organization?
pfSense has provided my current organization with remote access to the internal services and additional protection via its firewall.
What needs improvement?
I would like more add-ons/packages for extending pfSense which are approved by the main community.
For how long have I used the solution?
I have been using pfSense for the last five years, in three different companies in Denmark.
What do I think about the stability of the solution?
We never had any stability issues, even during high load usages.
What do I think about the scalability of the solution?
We never had any scalability issues. It's easy to add additional services, or even a second or third pfSense product which works with the others.
How are customer service and technical support?
Unfortunately, I never used the technical support. However, the community forums provided me with answers to the implementation and configuration questions that I had.
Which solution did I use previously and why did I switch?
I was using FortiGate and other firewall and VPN solutions. They were all ou0dated and too complicated to maintain. The change was made due to the ease of use of pfSense and the features that it provides.
How was the initial setup?
For an IT person, the setup was more or less straightforward.
What's my experience with pricing, setup cost, and licensing?
pfSense is free and open source software. Modification is easy and you can adapt it to your company's requirements.
Which other solutions did I evaluate?
As I already had experience with pfSense and I knew how it would help me and my company, I didn't evaluate other options.
What other advice do I have?
The product is flexible, scalable, and has logic in using it. It is easy to integrate and implement into your IT environment.
