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

"The solution is user-friendly and easy to configure."
"OPNsense impacts my projects and home network positively because its cost-effectiveness is perfect for lab and enterprise setup without expensive licensing, and the flexibility, easy VLAN and DMZ configuration supports different zones such as web servers, mail servers, and log servers."
"One of the most valuable features is the network checking. Additionally, the firewall and web filtering functionalities are highly useful."
"The system in general is quite flexible."
"With the VPN solutions, it is possible to cover up all the scenarios which we have."
"OPNsense is very stable, easy to upgrade, and maintain."
"The tool's integration is more like a button press."
"What I like the most about OPNsense is that it offers an easy-to-use dashboard for device management and control."
"It was easy to initially deploy it."
 

Cons

"In terms of improvement, the performance could be enhanced."
"To use Intrusion detection and Antivirus Plugin it is necessary to configure proxy; without a proxy, you cannot use the ClamAV antivirus plugin."
"The interface isn't so friendly user. But we have some technicians here who are quite confident with this tool. OPNSense could maybe add sets of rules so it's simpler to manage different groups with particular needs."
"We did not like the fact that you have to configure everything with the graphic user interface. We have used other firewalls, such as FortiGate, that you can configure via code. OPNsense is not easy to integrate. When you are deploying via GitHub or another source repository, this is not possible. That's one thing we didn't like much."
"The solution could be more secure."
"The monitoring is a little complicated and I have tried to use a plug-in, but it's quite complicated to configure."
"OPNsense could improve by making the configuration more web-based rather than shell or command-line-based."
"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

"We are not paying any licensing fees. OPNsense is completely free for us."
"It is free."
"As an appliance, it's in the medium price range."
"OPNsense is an open-source solution and it is free to use."
"The solution is not expensive."
"It costs about $1000."
"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."
"OPNsense is open source software so at this time it is free for us to use."
