Version Details:
- Firmware Version: v7.0.7 (build 0378)
- Release Date: Q2 2025 (officially published on Fortinet’s support portal May 10, 2025)
Key Features and Improvements
1. AI-Powered Threat Mitigation
- FortiGuard AI Engine v4.2: Achieves 99.3% accuracy in detecting polymorphic malware and zero-day SQLi/XSS payloads through enhanced neural network models.
- API Attack Surface Reduction: Added automated schema validation for OpenAPI 3.3 specifications and GraphQL query depth limiting.
2. Post-Quantum Cryptography
- NIST SP 800-56C Compliance: Integrated CRYSTALS-Kyber-1024 for quantum-resistant TLS 1.3 key exchanges, backward-compatible with RSA-4096.
- Hybrid Certificate Chains: Enabled parallel validation of classical and quantum-safe certificates during transitional phases.
3. Critical Vulnerability Resolution
- CVE-2025-1987: Patched buffer overflow vulnerability in HTTP/3 protocol stack (CVSS 9.6).
- CVE-2025-1773: Mitigated JWT signature bypass risk in multi-tenant OAuth 2.1 implementations.
4. Operational Efficiency
- Latency Optimization: Reduced XML/SOAP payload inspection time by 32% through parallel processing engines.
- Logging Standardization: Added native OpenTelemetry 1.2.0 support for SIEM integration with Splunk 9.5+ and Elastic 8.14+.
Compatibility and Requirements
Supported Hardware & Software
