I found the upgrades valuable.
FortiGate Next Generation Firewall (NGFW) offers easy setup with scalable performance, featuring SD-WAN, UTM protection, and user-based policies. Enhancements include SSL inspection and threat intelligence. Despite excellent security capabilities, pricing is high, support is poor, and stability issues such as memory leaks are present. Integration with FortiAuthenticator and VPNs is limited, while IPS needs improvement in vulnerability management. Rapid deployment is emphasized, yet technical support responses and better affordability are needed.
