IP Network Security Specialist at MTN Ghana

Process-Level CPU Visibility: Introduce detailed CPU-usage metrics per subsystem (e.g., IPS engine, logging) so administrators can quickly identify and address performance spikes.

Analytics with FortiAnalyzer. Being able to pull in logs not just from our FortiGates but from all our other firewalls and then get them in one view has been a game changer. Whether I’m building an executive dashboard or doing a deep dive forensics session, I get everything I need without navigating consoles.Straightforward Application Control. FortiGate spots and blocks unwanted apps (eq. like BitTorrent or streaming services) with accuracy. Segmentation with VDOMs. We’ve carved our data center into four logical ‘mini-firewalls’ enterprise, core, billing, and WAF—all on one box. Each has its own rules and logs, and any traffic between them still gets inspected. It’s like having multiple appliances without the extra hardware. Always-Up-to-Date Threat Feeds. Daily signature updates and AI-driven threat sensing mean we’re blocking the latest vulnerabilities almost as soon as they’re announced.

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.

ISO 27001 Lead Implementer at a consultancy with 11-50 employees

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

"OPNsense could be improved with a better wizard, as when I first installed it, it seemed difficult to know where to go."

"The reporting part could be better."

"The ability to set the VPN IP address would be a welcome addition."

"The monitoring is a little complicated and I have tried to use a plug-in, but it's quite complicated to configure."

More OPNsense cons

Pricing and Cost Advice

"The value is the capability of having multiple services with one unique license, not having the limitation per user licensing schema, like other vendors."

"This is not a cheap solution but it isn't expensive, either. It's a good solution for the right price."

"Pricing and licensing is a little bit complicated in FortiGate. They are always on the higher side. This is one issue that we always raise with the company that they should reduce the price according to Indian market requirements. There are no costs in addition to the standard licensing fees."
