It is a scalable solution. Approximately fifty people are using the solution.

It helps control the bandwidth, is scalable, easy to set up, and has a lot of data available on how to set it up
Pros and Cons
  • "What I like best about OPNsense is that, as a firewall, it's pretty good. I'm quite impressed with it. I had an excellent experience with OPNsense, which helped me achieve the targets I wanted."
  • "An area for improvement in OPNsense is the hardware, which needs to be updated more frequently. DNS blocking is another good feature I want to be added to the solution. pfSense has a peer-blocking feature that I also want to see in OPNsense."

What is our primary use case?

I'm using OPNsense as an open VPN and a firewall to control the traffic.

How has it helped my organization?

OPNsense improved my organization in terms of controlling the bandwidth. Limiting the bandwidth is the primary purpose of the solution in the organization.

What is most valuable?

What I like best about OPNsense is that, as a firewall, it's pretty good. I'm quite impressed with it.

I had an excellent experience with OPNsense, which helped me achieve the targets I wanted.

What needs improvement?

An area for improvement in OPNsense is the hardware, which needs to be updated more frequently.

An additional feature I want to see in OPNsense is a transparent proxy.

DNS blocking is another good feature I want to be added to the solution, as that helps make processes faster.

pfSense has a peer-blocking feature that I also want to see in OPNsense.

For how long have I used the solution?

I've been using OPNsense for more than one year.

What do I think about the stability of the solution?

OPNsense is a stable solution. Stability-wise, it's seven out of ten.

What do I think about the scalability of the solution?

OPNsense is a scalable solution, and I find it very good, but it still depends on your requirement and what you want to achieve from OPNsense.

How are customer service and support?

I didn't use OPNsense technical support because I resolved any issues myself.

Which solution did I use previously and why did I switch?

I used pfSense before using OPNsense, and OPNsense covered most of my environment's needs. My organization uses only one firewall, and that's OPNsense.

How was the initial setup?

Setting up OPNsense was easy for me. Even if you don't have experience, there is so much data available that you can follow so that the setup can be done easily.

The initial setup for OPNsense is an eight out of ten, especially if you know what you want to do and achieve from the solution. You also must try blocking methods based on what and how you want to block.

It took me two weeks to implement OPNsense completely. I set up the network and made a lab before using OPNsense in a production environment.

What about the implementation team?

We implemented OPNsense in-house.

What's my experience with pricing, setup cost, and licensing?

I'm using the free version of OPNsense. I didn't check the pricing for the solution because I still need to test it before getting the approval to purchase OPNsense, and it isn't easy to get approval from the higher-ups.

What other advice do I have?

I'm using two products, OPNsense and pfSense.

I upgraded to the latest version of OPNsense.

My organization is planning to move OPNsense to the cloud, in particular, hybrid cloud, but right now, it's deployed on-premises. Cloud deployment will be much more efficient than the current on-premises deployment, but I still need to test it before getting approval from the higher-ups.

Within my organization, fifty people use OPNsense because one department is trying it out. Still, when the solution is fully deployed, there could be from five thousand to six thousand users of OPNsense.

Ten to twelve people help maintain the solution yearly for the whole campus.

I advise anyone who wants to implement OPNsense to look into the suppliers and pick the right one because having the right supplier helps you achieve what you want from the solution.

My rating for OPNsense is eight out of ten.

Which deployment model are you using for this solution?

On-premises

Easy to scale, easy to setup, and reasonably priced
Pros and Cons
  • "OPNsense is easy to scale when running on the hardware."
  • "The interface needs to be simplified. It is not user-friendly."

What is our primary use case?

We upgrade our clients when they are ready for the newer versions of OPNsense.

We are one of the local cloud providers in Indonesia. We implement OPNsense for the VPN and IPSec. We also collaborate with Zerotier to provide SD-WAN.  

Our customers have solutions that integrate between on-premises and our cloud.

We provide this solution for several clients, in multi-location offices. We have several retail customers in the city and we provide OPNsense with plug-in remote access. 

We also use OPNsense for remote access, and IPSec gives them access to a cloud environment as well as on-premises.

What is most valuable?

OPNsense is easy to scale when running on the hardware.

What needs improvement?

The interface needs to be simplified. It is not user-friendly.

The bandwidth management is easy to use, but very hard to implement. The multi-provider internet is protected by OPNsence but the features are limited, and not stable.

The high availability feature is not feasible when the hardware fails.

We are also using pfSense.

How was the initial setup?

It takes one hour to deploy.

We provide maintenance for our clients at a cost, however, 90% of our clients are familiar with the product and able to maintain the solution themselves.

What about the implementation team?

We are implementors, and we provide this solution for our clients.

What's my experience with pricing, setup cost, and licensing?

As an appliance, it's in the medium price range.

OPNsense is suitable for Small to Medium-sized companies.

I would recommend this solution to others who are interested in using it.

Pros and Cons
  • "The initial setup is easy. It only takes 15-30 minutes to deploy."

    What is most valuable?

    The solution is easy to use and is accessible. I can also use it without paying. The configuration is very easy, and the website makes it easy to find help if you need it.

    So far, everything is okay. We've just started using the solution.

    As long as they continue to ensure that we are protected, it will be perfect.

    Which solution did I use previously and why did I switch?

    We did previously use another solution, but I don't recall the name. We didn't like the performance we were getting out of it.

    How was the initial setup?

    What about the implementation team?

    I handled the implementation myself.

    We use the private cloud deployment model.

    I would advise others thinking of implementing the solution to be aware of what you have to do to, and to plan it out beforehand. The solution is not for everybody, but it's not difficult to set up or maintain.

    I would rate the solution ten out of ten.
