1. Introduction to FGT_80F-v6-build1378-FORTINET.out

This firmware release delivers critical security patches and operational optimizations for FortiGate 80F next-generation firewalls deployed in small-to-medium enterprise networks. Published on May 12, 2025, build 1378 resolves 7 vulnerabilities identified through Fortinet’s Security Fabric telemetry while improving threat prevention throughput by 19% compared to v6-build1345.

Designed for the 80F hardware platform with integrated SPU content processors, this update enhances SD-WAN orchestration for hybrid work environments and introduces FIPS 140-3 Level 1 compliance modes. Compatibility spans standalone deployments running FortiOS 6.4.11 or newer, with specific optimizations for environments using dual WAN DSL links.
