- Mitigation of CVE-2025-48892 in FGFM protocol authentication
- Enhanced encryption for FortiCloud API communications using quantum-resistant algorithms
2. Operational Optimization
- IPSec Performance: 25% throughput increase for 10,000+ concurrent VPN tunnels
- HA Cluster Stability: Reduced failover latency to <0.3 seconds in active-active configurations
- Memory Management: Solved resource allocation issues during sustained 20 Gbps DDoS attacks
3. Protocol & Feature Enhancements
- Added full inspection support for QUIC v3 protocol
- Expanded Zero Trust Network Access (ZTNA) metadata logging for Azure AD integrations
- Updated FortiGuard threat intelligence to v25.445+ (2,300+ new malware signatures)
