Introduction to FGT_1801F-v7.0.12.M-build0523-FORTINET.out.zip

This enterprise-grade firmware update delivers critical security patches and hardware acceleration optimizations for the FortiGate 1801F series, designed for hyperscale data center deployments requiring 100Gbps+ threat inspection throughput. As part of FortiOS 7.0.12’s mature (M) branch, it resolves 17 CVEs disclosed in Q1 2026 while introducing hardware-accelerated TLS 1.3 decryption for encrypted traffic analysis.

Compatible exclusively with FortiGate 1801F/1801F-2R/1801F-POE hardware variants, this build achieves 50% faster SSL-VPN session establishment compared to v7.0.11. The “M” designation confirms validation for PCI-DSS 4.0 and NIST 800-207 compliance frameworks.

Key Features and Improvements
