Introduction to FGT_2500E-v7.2.4.F-build1396-FORTINET.out

This firmware package delivers FortiOS 7.2.4 for ​​FortiGate 2500E​​ next-generation firewalls, addressing critical security vulnerabilities while optimizing performance for large-scale enterprise and industrial control system (ICS) deployments. Released in ​​Q1 2025​​, build 1396 resolves 14+ security advisories documented in Fortinet’s March 2025 Security Bulletin. Designed for high-availability environments requiring advanced threat prevention, this update strengthens defenses against persistent attack vectors like CVE-2025-24472 authentication bypass exploits.

Compatible exclusively with FortiGate 2500E hardware appliances, the firmware requires existing FortiOS 7.2.x installations. System administrators managing multi-node HA clusters must deploy this update across all units within 24 hours to prevent configuration mismatches.

Key Features and Security Enhancements
