​​Introduction to FGT_100F-v6-build6812-FORTINET.out​​

This firmware package delivers critical security patches and performance enhancements for FortiGate 100F Next-Generation Firewalls operating on FortiOS 6.x. Designed for enterprise branch networks requiring advanced threat prevention, it resolves 6 CVEs while optimizing hardware resource allocation for SSL/TLS inspection and SD-WAN workflows.

The ​​build 6812​​ update targets FG-100F and FG-101F hardware models deployed in environments demanding simultaneous firewall, VPN, and application control capabilities. While exact release dates are not publicly documented, Fortinet’s firmware versioning patterns suggest this aligns with Q3 2025 security maintenance cycles for the 100F series.
