  • Patched CVE-2025-32890: Improper IPsec IKEv2 key validation vulnerability
  • Enhanced quantum-resistant cryptography support for government networks

​​2. Performance Optimization​​

  • SD-WAN traffic classification latency reduced by 31% through improved flow analysis
  • Maximum concurrent SSL inspection capacity increased to 22,000 sessions

​​3. Protocol Support Expansion​​

  • Implemented RFC 9293 (QUIC v2) deep packet inspection capabilities
  • Extended BGP EVPN support for multi-cloud environments

​​4. Management Improvements​​

  • REST API bulk configuration response times optimized to <160ms
  • Added zero-touch provisioning support for automated branch deployments

Compatibility Matrix

Component Supported Versions Notes
Hardware FG-401E Requires factory-default 16GB RAM configuration
FortiOS 7.0.10 – 7.0.13 Base image 7.0.10 required
FortiManager 7.6.3+ ADOM synchronization requires patch 05231
FortiAnalyzer 7.4.2+ GDPR-compliant logging verified
