Introduction to FGT_2500E-v6-build1232-FORTINET.out.zip Software
FGT_2500E-v6-build1232-FORTINET.out.zip is a firmware update package for Fortinet’s FortiGate 2500E enterprise firewall, released under FortiOS v6.4.24. Designed for large-scale data centers and service providers, this build delivers 120 Gbps threat inspection throughput while resolving critical vulnerabilities disclosed in Q1 2025 security advisories.
The firmware enhances the 2500E’s NP7 security processing unit (SPU) capabilities, enabling hardware-accelerated TLS 1.3 decryption for hyperscale environments. It integrates with Fortinet’s Security Fabric architecture to enforce unified policies across multi-cloud infrastructures including AWS GovCloud and Azure Government.
Release Date: January 2025 (Archived in Fortinet firmware repository)
Compatibility: Exclusively validated for FortiGate 2500E hardware running FortiOS v6.4.x.
