Introduction to FGT_3100D-v7.2.0.F-build1157-FORTINET.out
This firmware package delivers critical security patches and performance optimizations for Fortinet’s enterprise-grade FortiGate 3100D next-generation firewall. Released under FortiOS 7.2.0 branch (build 1157), it addresses multiple CVEs disclosed in Fortinet’s Q1 2025 PSIRT advisories, including vulnerabilities actively exploited in attacks against management interfaces. Designed for high-throughput data centers and critical infrastructure networks, this update enhances threat detection capabilities while aligning with NIST SP 800-207 Zero Trust Architecture guidelines.
Compatibility
Exclusively supports FortiGate 3100D hardware (FG-3100D series) with 100 Gbps firewall throughput capacity. Requires integration with FortiManager 7.4.7+ for centralized policy orchestration.
Version Specifications
