Introduction to FGT_2500E-v6-build0365-FORTINET.out Software
This enterprise-grade firmware update enhances security protocols and operational efficiency for FortiGate 2500E series firewalls under FortiOS 6.0 branch. Released in Q1 2025, build0365 resolves 4 critical CVEs identified in network security audits while optimizing resource allocation for hyperscale environments. Designed for data center deployments, it provides extended lifecycle support for organizations maintaining legacy FortiOS 6.0 infrastructure during cloud migration phases.
Compatible exclusively with FortiGate 2500E hardware (FG-2500E), this release requires FortiOS 6.0.12+ baseline configuration. The update follows Fortinet’s extended security maintenance policy, delivering critical vulnerability patches through Q4 2026 for high-availability cluster deployments.
