Open-source firewall has provided affordable real-time protection and secure remote access
In my opinion, OPNsense could improve by incorporating either an open side of wireless management or a way that you can also manage your interconnected devices. You could easily have SNMP, Simple Network Management Protocol, incorporated in it so that you can easily manage the devices and easily get the information about the devices that you are managing. Additionally, the inclusion of Pi-hole would allow you to create an ad-free network instead of adding it on a separate device. I would prefer that incorporated into OPNsense, or if it is there, I would appreciate guidance on how to use it.

Offers good scalability and monitoring features
There is room for improvement in the UI. They can improve it by making it so that everything is in one place, so we don't have to jump around to different pages. For example, if we're creating a rule, we should be able to do everything on the same page. Just a drop-down thing or something. This would improve productivity.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"I find everything valuable in OPNsense; the configuration and reporting aspects are what we require, reporting on user access and data consumed is fascinating in OPNsense, and the configuration offers a clear idea of everything that I have configured in DHCP."
"We can open a new VPN connection easily. It's much easier than with Fortinet in our experience."
"It is a very good solution. I like the dashboard. I can see what is going on and manage it as I like it."
"The solution is user-friendly and easy to configure."
"We saved up to half a million Egyptian pounds, which is nearly $100,000 yearly on licensing or subscription using this kind of software, and the network attacks reduced by approximately 60% after using that, even without customizing the custom configuration yet."
"OPNsense is very stable, easy to upgrade, and maintain."
"The solution is easy to use and is accessible."
"It has firewall and VPN capabilities, which are very valuable features."
"It was easy to initially deploy it."
 

Cons

"On the customer-side, because I'm a small business, I need a cheaper or free solution option."
"The solution would not be suitable for anything large-scale."
"The solution could be more secure."
"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."
"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."
"The IPS solution could be more reliable."
"There are a few weaknesses. For example, there is a lack of some features that I have in certain commercial products."
"The support for OPNsense is good because we have documents available on the internet. The support could improve a little."
"There is room for improvement in the UI. They can improve it by making it so that everything is in one place, so we don't have to jump around to different pages."
 

Pricing and Cost Advice

"OPNsense is open source software so at this time it is free for us to use."
"It is open source and free."
"It is a free solution, and when you compare it to alternatives like FortiGate, which is quite powerful but also costly, the value becomes evident."
"It is not an expensive product. Basically, I deployed it because it was the fastest solution to satisfy our needs in open source."
"I've used the free version. My computer with two network cards at home allows me to try as many different software options as I want. I did pay for the license, but it was for the Zenarmor license, which is the packet inspection tool. They use AI for packet inspection, which integrates with OPNsense and pfSense."
"OPNsense is an open-source solution and it is free to use."
"Its pricing is unbeatable in comparison to other firewalls. You can have a small instance that could be €80 a month with the hardware underneath. Azure Firewall and FortiGate are out of the question at this price. If you are on a public cloud, you need the underlying infrastructure. Other than that, there is no additional cost. If you have it on-prem, you have to buy the server or the appliance. The hardware cost is replaced with the infrastructure cost in the cloud. You also have costs for the public IPs and underlying VMs, but that's not related to OPNsense. It would be the same for a FortiGate deployment on Azure. You need a FortiGate license, and you need the underlying infrastructure that scales up depending on your needs."
"It is free."
