Introduction to FGT_91E-v7.0.2-build0234-FORTINET.out
This firmware delivers FortiOS 7.0.2 for FortiGate 91E series firewalls, designed for branch offices requiring enterprise-grade security in compact form factors. Released as a maintenance update in Q1 2025, it addresses 8 CVEs while optimizing memory allocation for environments using SD-WAN and Zero Trust Network Access (ZTNA) features.
The software targets FG-91E hardware platforms running FortiOS 7.0.x, featuring NP6Lite security processing and hardware-accelerated SSL inspection. Build 0234 resolves packet loss issues identified in earlier 7.0.2 versions, particularly affecting environments with >50 concurrent VPN tunnels.
