Senior Network Security Engineer at UNITE HERE HEALTH
Simplifies the management of complex data networks, but its technical support could be improved
Sometimes, we have to use SD-WAN support for the solution, which can be improved by adapting some features that will help our approach to network services. The solution can adapt some of the tools where we, as network engineers, can adjust to the changing application needs. Also, the solution can provide us with multiple support, allowing us to create a network segment. The solution’s technical support could be improved.

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.

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

Its user interface is one of the best interfaces I have used."
"YouTube provides video explanations, and that brings you to speed, instead of sitting down and reading a 200-page document on the product."
"The IDS and IPS features are valuable. From the usability perspective, there is a lot of good documentation. As IT professionals, we found it very easy to configure the firewall. It was easy to configure and use."

Cons

"Gajshield can improve SD-WAN compatibility at an enterprise cloud level."

"The UI for the administration of the firewall needs a lot of work."
"OPNsense can be improved by making it more user-friendly, as its current UI is not that user-friendly when compared to paid software such as Sophos."
"It is stable, but for us, it is not yet so reliable."
"In terms of improvement, the performance could be enhanced."
"The solution can't compete with next-generation firewalls."
"OPNsense could improve by making the configuration more web-based rather than shell or command-line-based."
"The reporting part could be better."
"The user interface could be improved, and the DNS section should be more intuitive."
