  2. ​​Throughput Optimization​​:

    • 18% improvement in IPsec VPN performance (up to 34 Gbps AES256-GCM)
    • 25% faster TLS 1.3 inspection throughput using NP7 security processors

  3. ​​Protocol Compliance Updates​​:

    • FIPS 140-3 Level 2 validation for government/military deployments
    • RFC 8903 compliance for improved BGP route reflector scalability

  4. ​​Management System Upgrades​​:

    • FortiManager 7.6+ compatibility for centralized policy deployment
    • SNMPv3 engine ID persistence across firmware upgrades
