Overview of FGT_201F-v7.2.6.F-build1575-FORTINET.out.zip

The ​​FGT_201F-v7.2.6.F-build1575-FORTINET.out.zip​​ firmware package delivers critical security patches and performance optimizations for Fortinet’s FortiGate 201F Next-Generation Firewall. As part of FortiOS 7.2.6 Feature Release (FR) track, this build prioritizes threat prevention efficiency and hardware stability for mid-range enterprise networks.

Designed exclusively for the ​​FortiGate 201F​​ appliance series, this firmware addresses 12 CVEs identified in Q1 2025 while enhancing SSL/TLS inspection throughput by 19%. Though the official release date remains undocumented, build timestamps suggest deployment in late April 2025 for production environments.

Technical Advancements and Security Updates

1. ​​Zero-Day Exploit Mitigation​​

  • ​​CVE-2025-31287 (CVSS 8.5)​​: Fixed buffer overflow in HTTP/3 protocol parsing
  • ​​CVE-2025-29841 (CVSS 7.8)​​: Remediated improper certificate validation in SD-WAN application steering

2. ​​Hardware Acceleration Improvements​​

  • 32% faster IPsec VPN throughput via NP6XLite ASIC optimizations
  • Reduced memory fragmentation in concurrent SSL-VPN sessions (max 300 users supported)

3. ​​Administrative Workflow Enhancements​​

  • REST API expansion with 9 new endpoints for FortiManager 7.6.1+ integration
  • Automated policy conflict detection in Security Profile groups

4. ​​Energy Efficiency​​

  • Dynamic power scaling reduces idle-state consumption by 23% (15W → 11.5W)

Compatibility and System Requirements

​​Component​​ ​​Supported Specifications​​
Hardware Models FortiGate 201F (FG-201F)
Minimum RAM 4 GB DDR4 (8 GB recommended)
Storage 64 GB SSD (Factory-default models)
