Introduction to FGT_201F-v6-build7241-FORTINET.out Software
FGT_201F-v6-build7241-FORTINET.out is an essential firmware update for Fortinet’s FortiGate 201F Next-Generation Firewall, designed to address critical security vulnerabilities while optimizing performance for enterprise branch networks. As part of the FortiOS 6.4.x Extended Security Maintenance (ESM) branch, this build (v6-build7241) targets memory allocation flaws identified during Q1 2025 penetration testing campaigns.
The firmware enhances threat prevention capabilities for the 201F platform’s NP6 security processor and maintains backward compatibility with configurations from FortiOS 6.2.15+. Compatible exclusively with the FortiGate 201F hardware model, this release focuses on hybrid cloud deployment security and SSL-VPN service hardening.
Key Features and Improvements
