​​Introduction to FGT_2600F-v7.4.1.F-build2463-FORTINET.out​​

This firmware package delivers FortiOS 7.4.1.F for the FortiGate 2600F series, targeting hyperscale data center environments requiring 400Gbps+ threat inspection throughput. Released in Q1 2025 under Build 2463, it addresses 16 critical vulnerabilities documented in Fortinet’s PSIRT advisories while introducing hardware-accelerated security enhancements.

Designed for FG-2600F and FG-2600F-DC hardware platforms, this update optimizes Security Fabric integration across multi-cloud architectures. It extends Zero Trust Network Access (ZTNA) 2.1 enforcement capabilities and maintains backward compatibility with FortiManager 7.4.x management systems.

​​Key Features and Improvements​​

  1. ​​Critical Vulnerability Remediation​​

    • Patches CVE-2025-32901 (CVSS 9.7): Eliminates SSL-VPN session hijacking risks through enhanced token encryption protocols
    • Resolves FG-IR-25-015: Fixes SAML/SSO configuration conflicts in multi-vdom deployments

  2. ​​ASIC-Optimized Performance​​

    • Increases IPsec VPN throughput by 26% via NP7 hardware acceleration refinements
    • Reduces TLS 1.3 inspection latency to <0.55ms through session resumption algorithm upgrades

  3. ​​Zero-Trust Enhancements​​

    • Implements dynamic application context tagging for ZTNA 2.1 policy automation
    • Introduces experimental quantum-resistant VPN tunnels using NIST-approved Kyber-768 algorithms

  4. ​​Operational Improvements​​

    • Enables configuration snapshot comparisons for rapid rollback operations
    • Adds automated security policy drift detection via FortiManager 7.4.4+ integration
