Introduction to FGT_40F-v6-build1190-FORTINET-6.2.7.out Software
The FGT_40F-v6-build1190-FORTINET-6.2.7.out firmware is a security-focused maintenance release for FortiGate 40F next-generation firewalls running FortiOS 6.2.7. Designed to address critical vulnerabilities and optimize network operations, this build serves as a mandatory update for organizations prioritizing perimeter defense integrity.
Compatible exclusively with the FortiGate 40F appliance, this firmware (build 1190) belongs to the FortiOS 6.2 branch. While exact release dates aren’t publicly documented, Fortinet’s quarterly security update cadence suggests this version was likely published in late 2023 to resolve emergent threats targeting SSL-VPN and firewall subsystems.
