Solution Architect at airtel

Enables customers to manage security effortlessly with intuitive features and easy integration

In terms of improvements for Fortinet FortiGate, they could offer evaluation licenses, as compared to Meraki, which provides a 90-day evaluation. In Fortinet FortiGate, they do not provide standard evaluation licenses; instead, we need to request them from the OEM through the account manager for POCs. If we want to conduct a demo, we need to work with real hardware. In comparison to Cisco, we have DCloud, which helps with providing demos to customers, but in Meraki, I need to reach out to them, book a lab, and they need to provide all the hardware. I need remote access and L3 engineers to program it; only then can I offer a real-time demo to the customer.

Centralized firewall management has saved time and improved network security across locations

Barracuda CloudGen Firewall could be improved as it has a very high learning curve. It is definitely not a one and done firewall, as a one and done firewall requires a lot of dedicated time to get the machine running the way you want. To improve Barracuda CloudGen Firewall, there should be a lot of tutorials and videos online to help new users. Multiple ways to configure for the same service or feature takes time to determine your customized build. In addition to previous points, the interface can sometimes be clunky when trying to determine how it is organized or arranged.

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.
