Introduction to FGT_3400E-v6.M-build2000-FORTINET.out.zip
This firmware package delivers critical security patches and operational optimizations for FortiGate 3400E series next-generation firewalls running FortiOS 6.4.M. As a Q3-2025 maintenance release, it addresses 19 CVEs while enhancing threat prevention efficiency for enterprise data center deployments.
The update targets organizations requiring FIPS 140-3 Level 2 compliance and supports NIST 800-53 Rev.5 security controls. Compatible hardware includes FortiGate 3400E (FG-3400E) and 3401E models with 128GB RAM configurations. Release logs confirm final validation on 2025-08-11 through Fortinet’s Secure Development Lifecycle (SDL) process.
