A stable solution with an intuitive interface and quick customer service

I have been working with Fortinet FortiGate, WatchGuard, Sophos, and SonicWall. I'm not as comfortable with SonicWall because of their UI and limitations. I prefer Fortinet above all other options. When it comes to configuration, I am confident in my ability to handle various tasks, including creating policies such as firewall rules, web policies, and application policies. Additionally, I can configure VPNs and implement load balancing, among other tasks. Overall, I feel much more comfortable working with Fortinet. Fortinet has made significant improvements by integrating AI with firewalls for threat analysis and prevention. In the past 2-3 years, they have launched FortiSASE and SIEM, and they also provide SOC services. Both Palo Alto and Fortinet FortiGate are excellent. While Fortinet FortiGate comes at higher prices, the functionality and support justify the cost. They promptly resolve firmware issues and inform all support providers about configuration changes.

Faced hardware limitations and setup challenges but have improved network protection over time

I spent much time finding exact firmware on Aruba which was working with these guns, but it is not optimal because it is not the latest version, so there could be potential security problems. We decided to replace those access points with another one. I personally have trouble because I don't know the exact life cycle of Fortinet FortiGate-VM boxes. I don't know if the life of boxes is five years or something else; we moved from our previous company, which sold us to other companies. Before 10 years, we had a special department that took care of core networks, including firewalls. After that, this responsibility fell to me and my colleague. It is not easy to set up these Fortinet FortiGate-VM boxes properly because we didn't have previous experience with this kind of solution. At first, we set up only a few rules that were not secure enough, and over a couple of years, we improved the settings and security of these Fortinet FortiGate-VM boxes. Currently, I have one Fortinet FortiGate-VM that needs to be replaced next year, and this box is not so powerful, so I need to redirect some traffic to another Fortinet FortiGate-VM. It is stable, but because the CPU processor of this box is not powerful, I need to redirect some traffic to another box. In the future, I need to choose a higher-level box to prevent potential troubles with the power of this box.

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.
