Designed for enterprises managing hybrid cloud workloads and IoT ecosystems, this update aligns with NIST 800-207 zero-trust architecture requirements and strengthens compliance with PCI-DSS 4.0 and HIPAA 2025 regulations.
Compatible Devices:
- FortiWeb 400C (Base model with 25Gbps TLS inspection throughput)
- FortiWeb 400C-ASM (Advanced Security Module for multi-layer DDoS protection)
Version Details:
- Build Number: v600-build1464
- Release Date: May 2025 (certified under Fortinet’s Q2 2025 Critical Infrastructure Security Program)
Key Features and Improvements
1. Zero-Day Vulnerability Mitigation
- Patches CVE-2025-15289 – a high-risk server-side template injection vulnerability in OpenAPI schema processors.
- Implements NIST-approved post-quantum encryption test vectors for management plane communications.
2. Advanced API Protection
- Introduces automated GraphQL query cost analysis to prevent resource exhaustion attacks.
- Enhances OAuth 2.1 token binding verification with dynamic key rotation support.
3. Cloud-Native Optimization
- Reduces Azure Front Door rule synchronization latency by 65% in multi-region deployments.
- Supports AWS WAFv3 integration with automated policy translation for 200+ security rules.
4. Operational Intelligence
- Integrates with Splunk Enterprise 10.0+ for real-time attack pattern correlation.
- Adds MITRE ATT&CK TTP mapping for all detected API security incidents.
Compatibility and Requirements
| Category | Specifications |
