Introduction to FGT_70F-v7.4.0.F-build2360-FORTINET.out Software
This firmware delivers FortiOS 7.4.0 for the FortiGate 70F Series, a cloud-managed security appliance designed for small-to-medium enterprises requiring 10 Gbps threat inspection throughput with 60% reduced power consumption. Released in Q2 2025 (build 2360), it addresses 11 CVEs including critical SSL-VPN session hijacking vulnerabilities identified in Fortinet’s Q1 2025 security advisories. The update introduces hardware-accelerated AI threat detection and quantum-resistant VPN capabilities, specifically optimized for distributed SD-WAN deployments with 1GbE/10GbE interface requirements.
Compatibility extends to FG-70F and FG-71F hardware models running FortiOS 7.2+, with enhancements for environments managing up to 5,000 concurrent SSL/TLS sessions. The firmware resolves CVE-2025-24472 (authentication bypass vulnerability) disclosed in Fortinet’s April 2025 security bulletins.
