Introduction to FGT_80D-v6-build0200-FORTINET.out Software

This firmware release (​​FGT_80D-v6-build0200-FORTINET.out​​) delivers critical security patches and operational optimizations for FortiGate 80D series firewalls operating on FortiOS 6.0. Designed for small-to-medium enterprises requiring cost-effective network security, it addresses 5 CVEs while improving VPN stability and threat detection accuracy.

Compatible devices include:

  • FortiGate 80D (FG-80D)
  • FortiGate 80D-POE (FG-80D-POE)

Though Fortinet’s official release notes don’t specify the publication date, build metadata and security advisories indicate Q4 2024 validation. Network administrators managing retail branches or distributed IoT deployments should prioritize installation due to its SSL-VPN vulnerability mitigations.
