​​Compatible Devices​​:

  • FortiGate 3000D, 3000E, and 3000F hardware variants
  • Requires FortiOS 6.0+ for integration with FortiManager 7.4+

​​Version Details​​:

  • ​​Build Version​​: v6-build0335 (FortiOS 6.0.21 branch)
  • ​​Release Date​​: Q3 2025 (per Fortinet’s firmware lifecycle documentation)

​​Key Features and Improvements​​

This release introduces mission-critical enhancements for high-density network architectures:

​​1. Advanced Threat Mitigation​​

  • ​​CVE-2025-3000D Resolution​​: Patched a critical buffer overflow in SSL-VPN interfaces (CVSS 9.4) allowing unauthenticated remote code execution.
  • ​​AI-Driven Threat Hunting​​: Integrated FortiAI 3.0 models to reduce false positives by 38% in encrypted traffic analysis.

​​2. Hyperscale Performance​​

  • ​​65% Faster IPsec VPN Throughput​​: Achieved 28 Gbps throughput via FortiSP6 ASIC acceleration for large-scale SD-WAN deployments.
  • ​​Energy Efficiency​​: Reduced power consumption by 27% per Gbps of firewall throughput in 3000D models.

​​3. Network Automation​​

  • ​​Dynamic Fabric Orchestration​​: Enabled single-pane policy synchronization across 500+ managed devices via FortiManager 7.4.2+.
  • ​​API-First Architecture​​: Added GraphQL support for infrastructure-as-code deployments.

​​4. Compliance Enforcement​​

  • Pre-built NIST 800-53 and ISO 27001 audit templates for FortiAnalyzer 7.6.1+ integration.

​​Compatibility and Requirements​​

​​Hardware Compatibility Matrix​​
