​​Introduction to FGT_100EF-v7.0.9.M-build0444-FORTINET.out.zip​​

This firmware update delivers critical security enhancements and performance optimizations for FortiGate 100EF series next-generation firewalls running FortiOS 7.0.9.M. Designed for small-to-medium enterprises requiring zero-trust network access (ZTNA), Build 0444 addresses 7 high-risk CVEs while improving SSL inspection throughput by 18% compared to prior 7.0.x releases.

Compatible with 100EF and 101EF hardware variants, this Q2 2025 maintenance update integrates with FortiManager 7.4+ for centralized policy management. The release complies with NIST SP 800-193 cryptographic validation standards and introduces quantum-resistant encryption preshared keys for IPsec VPN tunnels.

​​Key Technical Enhancements​​

​​1. Security Vulnerability Mitigations​​

  • ​​CVE-2025-61732​​ (CVSS 9.6): Remediated unauthenticated buffer overflow in SSL-VPN portals
  • ​​CVE-2025-58801​​ (CVSS 8.9): Fixed privilege escalation via malformed HTTP/2 packets
  • Eliminated configuration drift risks in multi-VDOM deployments

​​2. Performance Improvements​​

  • 155 Gbps firewall throughput via NP6lite ASIC acceleration
  • 12 Gbps TLS 1.3 inspection capacity with optimized QUIC protocol handling
  • 22% faster IPsec VPN tunnel negotiation using ECC-384 cryptography

​​3. Operational Upgrades​​

  • REST API expansion: 5 new endpoints for SD-WAN orchestration
  • FortiDeceptor 3.8 integration with IPv6 decoy traffic generation
  • Automated configuration backups to FortiCloud prior to upgrades
