Introduction to FGT_900G-v7.0.15.M-build7329-FORTINET.out.zip
This firmware package delivers critical updates for Fortinet’s FortiGate 900G series next-generation firewalls (NGFWs), designed to optimize security posture and network performance in enterprise data centers. Released in Q1 2025, FortiOS 7.0.15 addresses 18 CVEs rated critical/high severity and introduces 11 feature enhancements validated in NSS Labs’ 2025 Next-Gen Firewall benchmarks.
The “M-build7329” designation confirms it as a maintenance release under Fortinet’s lifecycle support for hardware platforms, specifically engineered for the 900G model equipped with NP7 network processors. It maintains backward compatibility with configurations from FortiOS 7.0.x while enabling experimental support for post-quantum cryptography (PQC) VPN tunnels.
