Introduction to FGT_3301E-v7.0.7.F-build0367-FORTINET.out.zip
This firmware package delivers critical security updates and performance enhancements for Fortinet’s FortiGate 3301E series next-generation firewalls, designed for enterprise-grade network protection in high-traffic environments. Released in Q1 2025, FortiOS 7.0.7 addresses 14 CVEs rated critical/high severity while introducing 8 feature optimizations validated in ICSA Labs’ 2025 NGFW certification benchmarks.
The “F-build0367” designation identifies it as a feature maintenance release under Fortinet’s lifecycle support program, specifically engineered for the 3301E model with dual NP7 network processors. It maintains backward compatibility with FortiOS 7.0.x configurations while adding experimental support for post-quantum cryptography (PQC) VPN tunnels.
