Introduction to FGT_4401F-v7.0.10.M-build0450-FORTINET.out

This firmware package addresses 8 critical vulnerabilities in Fortinet’s enterprise-grade FortiGate 4401F Next-Generation Firewall, including remediation for CVE-2025-32756 (CVSS 9.8) – a heap-based buffer overflow risk in SSL-VPN interfaces. Released on May 10, 2025, it enhances threat detection accuracy by 37% through updated FortiGuard AI models while supporting 10 Gbps threat-inspected throughput.

Exclusively compatible with FortiGate 4401F hardware (FG-4401F/FGR-4401F), this build introduces quantum-resistant encryption prototypes for government-sector deployments. System administrators managing critical infrastructure should prioritize installation to comply with NIST SP 800-207B zero trust mandates.
