What needs improvement?
The user interface could be improved, and the DNS section should be more intuitive.
For how long have I used the solution?
I have been using OPNsense for a few days. We use the updated version of the solution.

It allows me to assess our network traffic and has the best user interface
Pros and Cons
- "The VPN server feature is the most valuable. It is integrated with Radius and AAA for doing accounting and authentication. Insight view is also an important feature for me at this time. It allows me to assess our network traffic. I also like the firewall feature. The BSD kernel has a packet filter. It is one of the most solid frameworks for firewalls. Its user interface is one of the best interfaces I have used."
- "The only thing that I would like to see improved is the Insight or the NetFlow analysis part. It would be good to have the possibility to dig down on the Insight platform. Right now, we can easily do only a few analyses. If this page becomes more powerful, it surely will be a well-adopted platform."
What is our primary use case?
It is the main firewall for one of our locations. We use it for intrusion detection and prevention. We are using the latest software version, but the hardware is not the latest.

For how long have I used the solution?
I started to use OPNsense about three years ago.
What do I think about the stability of the solution?
It is stable, but for us, it is not yet so reliable. Our server is an old DL120 HP Server, which is from the year 2006. We have ordered another appliance. After we receive the new appliance, it would be more stable for us.
What do I think about the scalability of the solution?
It scales well for our needs. I haven't tried any horizontal or vertical scaling so far.
How are customer service and technical support?
I did not need any technical support.
Which solution did I use previously and why did I switch?
I used pfSense two years ago, but I was not so happy with our system protection. I have also previously used Cisco ASA appliance. It was a 5505 model, but it failed because of the hardware issues. It was prone to hardware failure, and in one month, we lost both firewalls. It was also not so easy to see traffic with Cisco ASA. I could not easily identify traffic issues.
How was the initial setup?
The initial setup was straightforward. I also have experience with BSD services, so I had no issues at all. It took us half an hour to deploy it for 250 users.
What about the implementation team?
We deployed it ourselves. There was no need for a consultant for the deployment. We have two engineers for its deployment and maintenance.
What's my experience with pricing, setup cost, and licensing?
It is not an expensive product. Basically, I deployed it because it was the fastest solution to satisfy our needs in open source.
What other advice do I have?
We plan to continue using this solution. Right now, we are settling our networks. We plan to expand its usage, but I don't think it will happen until 2022.
It has a good user interface. Its configuration is simple but requires a little planning. It is much simpler than the Cisco ASA configuration.
I would recommend this solution. I would rate OPNsense a nine out of ten. I am happy with it.
Which deployment model are you using for this solution?

How was the initial setup?
I believe the setup phase was a fusion of straightforwardness and complexity. It's not complicated, so it's fine.
It's deployed on-premises because we put it on our server, and it is hosted in Germany.
What's my experience with pricing, setup cost, and licensing?
It's a free solution.
What other advice do I have?
The solution requires no maintenance.
I would recommend OPNsense to others.

Free to use, easy to manage, and offers good security options
Pros and Cons
- "The initial implementation process is simple."
- "While they do have paid options that actually gives better features, for most of the clients, if they tend to take a paid option will instead opt for Fortinet."
What is our primary use case?
We just use the solution normally for its basic firewall functionality. OPNsense with WireGuard and CrowdSec bouncers handles all our requirements.
How has it helped my organization?
This is a free and secure solution that is easy to use.
What is most valuable?
The normal security options are great.
It's light and easy to manage.
The solution is very stable.
The initial implementation process is simple.
The solution offers a free version.
What needs improvement?
While they do have paid options that actually give better features, for most of the clients, if they tend to take a paid option will instead opt for Fortinet.
They should make it so that it's easier to reverse proxy integration.
For how long have I used the solution?
I have been using this solution for two years.
What do I think about the stability of the solution?
The product is quite stable and the performance is good. There are no bugs or glitches. It doesn't crash or freeze.
What do I think about the scalability of the solution?
We can easily scale the solution if we need to. It's not difficult.
How are customer service and support?
I've only used the free version of the solution. I just have to dig into the forums to find everything I need. There isn't a central place you can reach out to. I've found all the answers I've needed so far via the forums. There's a lot of information there.
How was the initial setup?
The initial setup is straightforward. It's not overly complex or difficult.
What's my experience with pricing, setup cost, and licensing?
We're a customer and an end-user.
We are using the telemetry-free version of the solution.
Overall, the solution is quite affordable.
Which other solutions did I evaluate?
I'm aware of Fortinet as well.
It depends on price versus performance. If you're willing to pay, Fortinet's great. If you don't have the budget, OPNsense is more affordable.
What other advice do I have?
We do supply the solution and we do use it for ourselves.
I'd advise users to get the Geo functionality. It's a nice add-on, which we make use of a lot. It allows which countries are allowed to access your instances, which is very helpful.
I'd rate the solution at a nine out of ten.
Which deployment model are you using for this solution?
On-premises

Founder/IT Consultant at Open IT World
A secure, stable and reliable solution
Pros and Cons
- "It's more secure and more reliable."
- "The IPS solution could be more reliable."
What is our primary use case?
I moved to OPNsense because it's more secure and more reliable. I use it to secure access to the servers. I have a core backing server, an e-banking server, the main server, and other features with the solution. I make the multi-DMZ packs, so each service is in one DMZ bay, and I use it as a virtual chain.
What is most valuable?
The firewall solution is okay because it is like pfSsense.
What needs improvement?
The IPS solution could be more reliable. The IPS functioning and internal prevention system functioning could be added to the system. I didn't have it in pfSense, which is why I'm moving to OPNsense, but it is still not working well. They could also have the LZN ones.
For how long have I used the solution?
I have been using this solution for about four years, and I am using the latest version, OPNsense 21.
What do I think about the stability of the solution?
It is very stable, and I rate the stability a ten out of ten.
What do I think about the scalability of the solution?
It is a scalable solution, but I didn't try to scale it because I just used one instance.
How are customer service and support?
I don't use technical support. Instead, I use community resources because they give me all the necessary solutions.
How was the initial setup?
It is easy to set up, and the deployment took about six months.
What's my experience with pricing, setup cost, and licensing?
The price is good and is better than other computer solutions. The licensing cost is zero because you only have to buy the support. I believe that costs between $900 to $1000 a year.
What other advice do I have?
I rate this solution a nine out of ten. Regarding advice, if they want to use this solution, they have to know how they want to organize the actual networking. When it is well organized, you can easily deploy OPNsense inside it.
