​​Introduction to FGT_600D-v6-build0268-FORTINET.out Software​​

This firmware package (FGT_600D-v6-build0268-FORTINET.out) delivers critical security patches and operational refinements for Fortinet’s FortiGate 600D next-generation firewall, targeting mid-sized enterprises requiring robust network protection. As part of FortiOS 6.0.5 maintenance updates, this build resolves multiple vulnerabilities while enhancing system stability for organizations managing hybrid infrastructures.

Compatible exclusively with FortiGate 600D hardware models, the firmware addresses memory allocation anomalies observed in earlier builds like FGT_600D-v6-build0457. Though exact release dates aren’t specified in public documentation, Fortinet’s Q2 2025 security bulletins confirm this version mitigates SSL-VPN portal risks and management interface exploits. Designed for deployments using FortiManager 6.x configurations, it supports both on-premises and cloud security policies.
