​​1. Introduction to FGT_60F-v6-build1319-FORTINET.out.zip​​

This firmware update delivers critical security hardening and operational optimizations for FortiGate 60F Next-Generation Firewalls running FortiOS 6.4.x. Released under Fortinet’s Q2 2025 security maintenance cycle, build 1319 addresses 8 documented vulnerabilities while enhancing threat prevention capabilities for small-to-medium business networks. Designed specifically for the 60F hardware platform, this update improves SSL-VPN stability and SD-WAN performance in distributed office environments.

The software corresponds to FortiOS 6.4.13 interim release, bridging functionality between major version upgrades. It maintains backward compatibility with configurations from FortiOS 6.2.x while introducing mandatory security enhancements for IPsec VPN implementations.
