I found the upgrades valuable.
FortiGate Next Generation Firewall (NGFW) is user-friendly with high performance and stability from next-generation features like IPS and user-based policies. It offers SSL inspection, VPN, and support for high ROI but requires better technical support and vulnerability management. Scalability and integration flexibility enhance security, yet high pricing and stability issues are challenges. More SD-WAN features are needed for improved performance. Buyers consider FortiGate a reputable but pricey option.
