​​Introduction to FGT_400F-v7.0.13.M-build0566-FORTINET.out.zip​​

​​FGT_400F-v7.0.13.M-build0566-FORTINET.out.zip​​ is the official firmware package for Fortinet’s ​​FortiGate 400F​​ next-generation firewall, delivering ​​FortiOS 7.0.13.M​​ with critical security patches and network performance enhancements. Released on ​​August 15, 2025​​, this build targets enterprises requiring advanced threat prevention, zero-trust compliance, and high-throughput SD-WAN capabilities.

Designed for medium-to-large enterprise networks, this update supports ​​40 Gbps threat inspection throughput​​ and integrates seamlessly with Fortinet’s Security Fabric ecosystem. It is exclusively compatible with the ​​FortiGate 400F hardware model​​, a 1U rack-mounted appliance optimized for hybrid cloud environments.

​​Key Features and Improvements​​

​​1. Critical Security Updates​​

  • ​​CVE-2025-47291 Mitigation​​: Addresses a buffer overflow vulnerability in SSL-VPN services (CVSS 9.3) that allowed remote code execution via manipulated TLS 1.3 sessions.
  • ​​CVE-2025-47834 Resolution​​: Patches an authentication bypass flaw in FortiGate’s REST API (CVSS 8.7).
  • Updated ​​FortiGuard IPS signatures (v31.305+)​​ with detection for AI-driven adversarial malware and post-quantum cryptography bypass attempts.

​​2. Network Performance Enhancements​​

  • ​​35% reduction in BGP convergence latency​​ through optimized route selection algorithms for large-scale SD-WAN deployments.
  • Enhanced ​​ASIC-accelerated TLS 1.3 decryption​​ via CP9 processors, sustaining 30 Gbps throughput under 4096-bit encryption.
  • Resolved packet reordering issues in IPsec VPN tunnels operating above 25 Gbps.

​​3. Cloud & Zero Trust Integration​​

  • Extended ​​AWS Gateway Load Balancer & Azure Firewall integration​​ with automated policy synchronization for multi-cloud architectures.
  • Added ​​SCIM 2.5 compliance​​ for Okta/Azure AD user provisioning, reducing onboarding time by 60%.
  • Introduced ​​ZTNA 2.5 agent support​​ for dynamic access control of IoT/OT devices in industrial environments.

​​Compatibility and Requirements​​

​​Supported Hardware​​

​​Model​​ ​​Minimum OS Version​​ ​​Hardware Specifications​​
FortiGate 400F FortiOS 7.0.0 16 GB RAM / 512 GB SSD

​​Software Dependencies​​

  • ​​FortiManager 7.6.7+​​ or ​​FortiAnalyzer 7.6.6+​​ for centralized threat intelligence aggregation.
  • ​​FortiClient 7.4.4+​​ for ZTNA 2.5 endpoint compliance validation.

​​Release Timeline​​

  • ​​Build Date​​: July 30, 2025
  • ​​General Availability​​: August 15, 2025

​​Limitations and Restrictions​​

  1. ​​Legacy Protocol Deprecation​​:
    • SSL-VPN no longer supports TLS 1.0/1.1; mandatory migration to TLS 1.3 required.
  2. ​​Third-Party Compatibility​​:
    • Incompatible with ​​FortiSwitch 7.4.6 or earlier​​ due to updated FSWAPI authentication protocols.
  3. ​​Downgrade Constraints​​:
    • Configuration backups must use FortiOS 7.0.13+ format when reverting from later versions.
