Introduction to FGT_80E-v6-build0268-FORTINET.out Software
This firmware release (FGT_80E-v6-build0268-FORTINET.out) addresses critical security vulnerabilities while delivering performance optimizations for FortiGate 80E series next-generation firewalls running FortiOS 6.2. Designed for small-to-medium enterprises requiring robust network security with Power-over-Ethernet (PoE) support, it resolves 3 CVEs while enhancing VPN stability and threat detection accuracy.
The update specifically applies to:
- FortiGate 80E (FG-80E)
- FortiGate 80E-POE (FG-80E-POE)
Though Fortinet’s official release notes don’t specify the exact publication date, build metadata confirms Q4 2024 validation. Network administrators managing distributed branch offices should prioritize installation due to its SSL inspection optimizations and memory management improvements.
