Introduction to FGT_80D-v6-build0231-FORTINET.out.zip

This firmware package provides critical security patches and operational optimizations for FortiGate 80D series firewalls running FortiOS 6.0.x. Released under Fortinet’s Q4 2024 Security Maintenance Release (SMR) program, build0231 resolves 7 CVEs affecting VPN services, web filtering subsystems, and management interfaces while maintaining backward compatibility with existing network configurations.

Designed for FG-80D appliances deployed in small business and remote office environments, this update integrates cumulative fixes from FortiOS 6.0.8 while introducing hardware-specific enhancements for the NP4 network processor. The .zip archive contains firmware binaries, SHA256 checksums, and PGP signatures for enterprise-grade validation.
