1. Introduction to FGT_1101E-v7.0.8.F-build0418-FORTINET.out.zip

This firmware package delivers critical security hardening for FortiGate 1101E next-generation firewalls, specifically addressing SSL-VPN vulnerabilities identified in Q1 2025 attack patterns. Released on April 18, 2025 as part of FortiOS 7.0.8 Feature Release updates, build “0418” implements mandatory security controls mandated by Fortinet’s Product Security Incident Response Team (PSIRT) advisory FG-IR-25-147.

Designed for mid-sized enterprises requiring 20+ Gbps threat inspection throughput, this update enhances integration with FortiManager 7.6.3 centralized management platforms. The 1101E series now supports automated security policy synchronization across hybrid cloud environments and improved SD-WAN application steering capabilities.
