  • Achieves 24.5Gbps sustained throughput with IPS/Web Filtering enabled
  • Reduces SSL inspection latency by 28% for TLS 1.3 encrypted traffic

​​3. Fabric Management Upgrades​​

  • Introduces REST API endpoint /api/v2/monitor/system/automation-stitch/health-metrics
  • Fixes FortiManager configuration synchronization delays reported in builds 2001-2025
  • Enables SNMPv3 SHA-512 authentication for compliance monitoring

​​4. SD-WAN Operational Enhancements​​

  • Adds dynamic SLA path selection for Microsoft Azure AI Services traffic patterns
  • Updates application signature database with 53 new SaaS/IoT identifiers
  • Implements 200ms SLA probe timeout threshold for AWS Direct Connect environments
