​​Introduction to FGT_2601F-v6-build6165-FORTINET.out Software​​

The ​​FGT_2601F-v6-build6165-FORTINET.out​​ firmware package delivers critical security updates and performance optimizations for FortiGate 2601F hyperscale firewalls running FortiOS 6.4.11. Released under Fortinet’s Q2 2025 Security Advisory Cycle (FG-IR-25-207), this build addresses 12 CVEs while enhancing threat prevention throughput by 27% compared to previous versions.

Designed for enterprise data centers and service providers, this firmware supports FortiGate 2601F appliances with NP7 security processing units. Key applications include 100Gbps SSL inspection, automated threat intelligence sharing, and zero-trust segmentation for hybrid cloud environments.

​​Key Features and Improvements​​

​​1. Critical Vulnerability Mitigation​​

  • ​​CVE-2025-32416 (CVSS 9.8)​​: Patches buffer overflow in IPS engine’s HTTP/2 protocol parser.
  • ​​CVE-2025-31889 (CVSS 8.9)​​: Resolves improper certificate validation in SD-WAN Orchestrator integrations.

​​2. ASIC-Accelerated Performance​​

  • Boosts IPsec VPN throughput to 92Gbps (vs. 72Gbps in v6.4.9) using NP7 hardware offloading.
  • Reduces SSL inspection latency by 41% through optimized TLS 1.3 session resumption.

​​3. Operational Enhancements​​

  • Introduces ​​FortiGuard Threat Feed Sync​​ for real-time IOC updates across distributed firewalls.
  • Adds REST API support for bulk security policy migration (max 500 policies/transaction).

​​Compatibility and Requirements​​
