Introduction to FGT_2201E-v6.M-build2095-FORTINET.out.zip

This firmware package delivers FortiOS 6.M Build 2095 for FortiGate 2201E next-generation firewalls, specifically engineered for distributed enterprise branch security. Released in Q1 2025 through Fortinet’s Security Fabric Update Program, this critical maintenance update addresses 16 identified vulnerabilities while optimizing threat detection efficiency by 19% in real-world deployments.

Designed for FG-2201E hardware platforms (including 2201E, 2201E-3G4G variants), this build implements hardware-accelerated TLS 1.3 decryption and introduces granular SD-WAN path control capabilities. The update maintains backward compatibility with FortiOS 6.4.x configurations while enabling new Zero Trust Network Access (ZTNA) features.
