Introduction to FGT_4201F-v7.0.15.M-build0632-FORTINET.out Software
The FGT_4201F-v7.0.15.M-build0632-FORTINET.out firmware is a critical security and performance update for Fortinet’s FortiGate 4201F Next-Generation Firewall (NGFW), designed for large enterprises and data centers requiring 100Gbps+ threat inspection throughput. As part of FortiOS 7.0.15.M, this build integrates NP7 ASIC optimizations and addresses 12 CVEs disclosed in Q2 2025 security advisories.
Exclusive to FortiGate 4201F series appliances, this firmware supports models with hardware-accelerated security processing and hyperscale SD-WAN capabilities. While the official release date isn’t public, build metadata suggests availability through Fortinet’s support portal since May 2025 for registered partners.
Key Features and Improvements
