User-Friendly, improves security, and gives me more control over my VoIP
We purchased the solution and we are partners. I haven't had a chance to go through all of the features and what this solution offers, but I think that it has an integrated VPN. I am looking forward to using another VPN. I am anxious to see it, as we are going to set that up for one of the clients. At this time, I am not able to add any comments on how this solution can be improved, because this solution does what it is asked to do. I would rate this solution an eight out of ten.

Has helped simulate enterprise security setups and strengthens network segmentation practices
For my capstone, I use OPNsense for my project and its broader benefits for enterprise and cybersecurity context. OPNsense is an open source based firewall and routing platform. It offers enterprise-grade features such as intrusion detection and prevention system, VPN support, traffic shaping, and web filtering, all without license cost. This platform has a modular design, a clean web-based GUI, and frequent updates that prioritize security and usability. It competes with commercial firewalls such as Cisco ASA, FortiGate, and Palo Alto, but stands out because it's community-driven, cost-effective, and transparent. I find OPNsense's feature of acting as a central firewall and gateway most valuable, providing robust point segmentation between the internal network and DMZs in my capstone project, intrusion detection to monitor malicious traffic, VPN services for secure remote access, and logging and monitoring for compliance and auditing. This allows me to simulate a real-world enterprise environment on a smaller scale, demonstrating both security hardening and network efficiency. OPNsense impacts my projects and home network positively because its cost-effectiveness is perfect for lab and enterprise setup without expensive licensing. The flexibility, easy VLAN and DMZ configuration supports different zones such as web servers, mail servers, and log servers. The security-first design for IDS/IPS integration helps me showcase modern defense-in-depth strategies. The user-friendly management through the web GUI makes it possible to manage complex firewall rules clearly, which is critical when documenting and presenting a capstone. Scalability is also an advantage. Although my project is lab-based, OPNsense can scale into production deployments in SMBs and enterprise.

Quotes from Members

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

Pros

"This solution is user-friendly."
"This solution has given me more security, I have more control over my VoIP solution, and I can pick up separate VNs."
"The solution is user-friendly and easy to configure."
"The DNS-level filtering is impressive for thwarting time scanners."
"OPNsense is suitable for Small to Medium-sized companies."
"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."
"YouTube provides video explanations, and that brings you to speed, instead of sitting down and reading a 200-page document on the product."
"OPNsense is easy to use and open source."
"The most valuable feature of OPNsense is compatibility."
"It is a very good solution. I like the dashboard. I can see what is going on and manage it as I like it."
 

Cons

"I haven't seen any feature that will allow me direct authentication for a VPN solution."
"The reporting part could be better."
"SD-WAN (software-defined wide area network) is integrated into some restricted service providers for OPNSense."
"The ability to set the VPN IP address would be a welcome addition."
"FortiGate is a better firewall but that is commercial software that you have to buy a license for."
"OPNsense struggles to handle large volumes of voice traffic, indicating scalability issues in that specific use case."
"I would like better documentation concerning the provided packages and their integration."
"The scalability needs improvement."
"I would like to see better SD-WAN performance."
 

Pricing and Cost Advice

Information not available
"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."
"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."
"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."
"We are using the paid version."
"We are not paying any licensing fees. OPNsense is completely free for us."
"It costs about $1000."
"It is not an expensive product. Basically, I deployed it because it was the fastest solution to satisfy our needs in open source."
