Introduction to FGT_3501F-v7.0.14.M-build0601-FORTINET.out
The FGT_3501F-v7.0.14.M-build0601-FORTINET.out firmware delivers enterprise-level security enhancements and operational optimizations for Fortinet’s FortiGate 3501F next-generation firewall platform. Released on May 9, 2025, as part of FortiOS 7.0.14 Maintenance Release (MR), this build addresses 21 documented vulnerabilities while improving hardware resource allocation for hyperscale network environments.
Designed for the 4U chassis FortiGate 3501F series – supporting up to 1.8 Tbps firewall throughput – this firmware maintains backward compatibility with configurations from FortiOS 7.0.12+. The update specifically targets enterprise data centers requiring compliance with NIST SP 800-207 Zero Trust Architecture guidelines and PCI-DSS v4.0 security standards.
