​​Compatible Infrastructure​​:

  • ​​Primary Hardware​​: FortiWeb 400C appliance series
  • ​​Security Fabric Integration​​: FortiManager 7.6.3+, FortiAnalyzer 8.1+

​​Version Specifications​​:

  • ​​Build Version​​: v7.0-build0140
  • ​​Release Date​​: May 9, 2025 (aligned with Fortinet’s 30-day critical patch schedule)

​​Key Features and Improvements​​

​​1. AI-Driven Threat Prevention​​

  • ​​Behavioral API Protection​​: Detects OWASP API Top 10 risks through FortiGuard’s neural network analysis with 99.3% accuracy.
  • ​​Quantum-Safe TLS 1.3​​: Implements NIST-approved CRYSTALS-Kyber-1024 algorithm alongside ECDHE-384 for hybrid encryption.

​​2. Critical Vulnerability Mitigation​​

  • ​​CVE-2025-34012​​ (CVSS 9.4): Patches remote code execution in GraphQL query validation.
  • ​​CVE-2025-33128​​ (CVSS 8.8): Resolves JWT token spoofing in multi-tenant configurations.

​​3. Performance Optimization​​

  • ​​45 Gbps SSL Inspection​​: 25% throughput improvement over v7.0-build0135 using 64-byte packets.
  • ​​60% Faster Policy Activation​​: Enhanced rule compilation reduces deployment latency to <6 seconds.

​​4. Extended Protocol Support​​

  • HTTP/3 (QUIC) full-stack analysis
  • gRPC bidirectional streaming inspection

​​Compatibility and Requirements​​

​​Component​​ ​​Requirement​​
​​FortiWeb Hardware​​ 400C, 500D
​​FortiOS Version​​ 7.4.3 or later
