IT Consultant at a tech services company with 1-10 employees
Easy-to-use interface, with good web blocking and it's open-source
Pros and Cons
- "The interface is straightforward and easy to use."
- "Also, simplifying the rules for the GeoIP. Making it simpler to understand would be an improvement."
What is our primary use case?
The primary use case of this solution is to protect our business network.
What is most valuable?
I like the fact that it is open-source.
The Surakarta and the web blocking functionality seems to be quite good. It's not perfect, but none of them are.
The interface is straightforward and easy to use.
What needs improvement?
I would like to see the dashboard modernized.
If you look at some of the other providers, their dashboard is more modern looking.
Also, simplifying the rules for the GeoIP. Making it simpler to understand would be an improvement.
For how long have I used the solution?
I have been using pfSense for approximately one year.
What do I think about the stability of the solution?
It seems to be relatively stable. I haven't had very many issues.
If I do have any issues, it is more to do with the way that I have configured it. Other than that, it works fine.
What do I think about the scalability of the solution?
It's a scalable solution. We have 14 computers with more powerful hardware that allows us to deal with larger networks.
Apart from what you see on the interface, you can also use the command line to create a cluster if you need to.
How was the initial setup?
The initial setup is straightforward once you read the manual.
Which other solutions did I evaluate?
I did evaluate another solution but felt that the cost was too high for what it was. Based on the consumer market, I didn't feel that it was at the enterprise level.
What other advice do I have?
I would recommend reading the manual and the administration book. It has all of the proper information.
Many will jump into pfSense without reading the manual properly, or taking the time to understand the definitions, and how to set it up properly.
If you don't, then you might have a bad experience, which would not be fair to the product.
To give a fair comparison and trial, definitely read the technical documentation before implementing it.
Given the fact that it's open-source, relatively easy to use, and it seems to do the job quite well, I would rate pfSense a ten out of ten. I think it deserves that.
Which deployment model are you using for this solution?
On-premises

What is our primary use case?
We use pfSense for our firewall protection.
What is most valuable?
The most valuable features are ease of installation and support.

I would like to see different graphs available in the reporting.
For how long have I used the solution?
We have been using pfSense for two months.
What do I think about the stability of the solution?
pfSense is quite stable. It is one of the pros.
What do I think about the scalability of the solution?

We get very little usage and have no plans to increase it.

The technical support is A+, pretty good.
How was the initial setup?
The initial setup was straightforward.
What's my experience with pricing, setup cost, and licensing?

Founder and MD at Smart Solution
The intrusion detection capabilities work well
Pros and Cons
- "My company mainly works in the health and educational domain, schools and universities. I prevent the improper use of content from schools and universities. I defend the medical records for the patients in our hospitals. That is the main use case for me for the firewall."
- "pfSense is not user-friendly. I hope to have something to make the interfaces more user-friendly."
What is our primary use case?
My primary use case for pfSense is as a firewall. We also use it for intrusion detection, intrusion prevention, website filtering, and quality of service (QoS).
How has it helped my organization?
My company mainly works in the health and educational domain, schools and universities. I prevent the improper use of content from schools and universities. I defend the medical records for the patients in our hospitals. That is the main use case for me for the firewall.
What is most valuable?
One of the most valuable features of this solution is that it's almost entirely free and I can do everything with it.
What needs improvement?
It has everything I need, but the main drawback of pfSense is that it's not user-friendly. I hope to have something to make the interfaces more user-friendly. I would also like to see some documentation that can help with use cases or that has advice and tips. I have found some documentation available but it's usually from an earlier version. If they develop this, pfSense will be the best. The only thing that Fortigate is better than pfSense is that they have 24/7 support. pfSense also needs improvements in the intrusion detection area.
For how long have I used the solution?
Three to five years.
What do I think about the stability of the solution?
I depend on and use VMware ESXi with vSphere in my deployment, virtualization. pfSense is more stable and reliable if you install it directly on the server, i.e. not being installed as a virtual machine. That makes it very stable.
What do I think about the scalability of the solution?
The scalability is good. You can integrate some nodes of pfSense but it's not very user friendly.
How are customer service and technical support?
I would be more relieved and more happy to have support. You need to have some people who can help you in any use case.
How was the initial setup?
Lots of reading and trial and error. It's tough for the network engineer, but it is magnificent in performance from my point of view.
What about the implementation team?
We implemented in-house. Not user friendly, but if you want to do anything you can do it with pfSense.
What was our ROI?
Free. Would purchase for better customer support.
What's my experience with pricing, setup cost, and licensing?
It is completely free.
Which other solutions did I evaluate?
We also evaluated Fortigate.
What other advice do I have?
I would rate this solution an eight out of ten. I give it this rating because of the rich features available. pfSense is free and I can do everything with it. It works as a firewall for servers also.

Chief Technology Officer at Xpro Networks
Compatible with VoIP platform and is easy to understand
Pros and Cons
- "We generally use it because it's cheap. When we need something more robust we use Barracuda and Sony Wireless Routers. For certain clients, we use pfSense because it's compatible with the VoIP platform."
- "I would like to see SD1 integration into the software. That would be fantastic."
What is our primary use case?
We use pfSense as our firewall.
How has it helped my organization?
We install it for clients that don't have a network available or the network is not ready for phone deployments. We're a phone company. We use pfSense to connect to the router and normally we connect clients to client VPNs, and then from there, we can have access to the internal network so that we can see all of the files.
What is most valuable?
We generally use it because it's cheap. When we need something more robust we use Barracuda and Sony Wireless Routers. For certain clients, we use pfSense because it's compatible with the VoIP platform.
What needs improvement?
I would like to see SD1 integration into the software. That would be fantastic.
For how long have I used the solution?
Three to five years.
What do I think about the stability of the solution?
The solution is pretty stable, that's why we use it. There aren't any problems.
What do I think about the scalability of the solution?
The scalability is fine. If you need to have a bigger client or something like that, it's simple. You do a backup and then you restore into a new appliance and go from there.
How are customer service and technical support?
We provide technical support for our clients so we don't use a third party company for the support, we do the support in-house.
Which solution did I use previously and why did I switch?
We also use MikroTik, Barracuda, and StoneWall.
How was the initial setup?
The initial setup is fairly simple, not complex. We can get the deployment done in around half an hour.
What about the implementation team?
We deploy pfSense for our clients. We have one technician maintaining the whole thing.
What was our ROI?
Our return on investment is fast. We see a return on investment from day one, it's a fairly cheap router.
What other advice do I have?
Any network engineer will understand how this solution works. It's not so complex to understand and be familiar with. It will require a certain level of networking knowledge to use it but we're at an enterprise level and we're a small-medium business and it works.
I would rate it a nine out of ten.
