Introduction to FGT_3501F-v7.2.3.F-build1262-FORTINET.out
This enterprise-grade firmware release delivers critical security enhancements for FortiGate 3501F Next-Generation Firewalls, specifically designed for hyperscale data center operations. As part of FortiOS 7.2.3 security branch updates, build 1262 resolves 14 CVEs identified in FortiGuard PSIRT advisories (Q1-Q2 2025) while achieving 2.4 Tbps threat inspection throughput – a 28% improvement over previous 7.2.x versions.
Exclusively compatible with FortiGate 3501F chassis systems, this update introduces hardware-accelerated TLS 1.3 decryption and enhanced SDN integration with VMware NSX-T 4.1+ environments. The release follows Fortinet’s May 2025 security update cycle, prioritizing protection against advanced persistent threats targeting financial infrastructure.
