Introduction to FGT_80E-v7.2.5.F-build1517-FORTINET.out

This firmware package delivers FortiOS 7.2.5 for FortiGate 80E next-generation firewalls, addressing 11 critical vulnerabilities while optimizing threat prevention capabilities for medium-sized enterprise networks. Released in Q2 2024 under Fortinet’s quarterly security maintenance program, build1517 provides enhanced SSL-VPN stability and improved Security Fabric synchronization mechanisms.

Compatible exclusively with FortiGate 80E hardware platforms (including 80E-3G4G variants), this update focuses on certificate management optimizations and memory leak resolution observed in previous 7.2.x releases. Network administrators managing distributed offices will benefit from its refined deep packet inspection (DPI) engine and BGP route convergence improvements.
