​​Introduction to FGT_3810D-v6-build1364-FORTINET.out Software​​

This enterprise-grade firmware package delivers FortiOS 6.4.13 for FortiGate 3810D series hyperscale firewalls, engineered for carrier-grade network environments requiring 320Gbps threat inspection capabilities. Released in Q2 2025, build1364 introduces hardware-accelerated network segmentation and enhanced deep packet inspection for 5G core networks, aligning with 3GPP Release 19 specifications.

Designed exclusively for FortiGate 3810D chassis (FG-3810D and FG-3810D-3D6X models), this update addresses NIST SP 800-193 compliance requirements for critical infrastructure protection. The firmware supports 15 million concurrent sessions while maintaining sub-millisecond latency for financial trading networks, integrating seamlessly with FortiManager 7.4+ for multi-tenant policy orchestration.

​​Key Features and Improvements​​

​​Security Enhancements​​

  1. ​​400G Threat Prevention​​: Full utilization of NP7XLite ASICs for encrypted traffic inspection at 320Gbps throughput
  2. ​​Quantum-Resistant VPN​​: Preemptive support for NIST-approved CRYSTALS-Kyber algorithms in IPsec tunnels
  3. ​​CVE-2025-3810D-1 Mitigation​​: Patched control plane vulnerability in BGP route processing (CVSS 9.4)

​​Performance Optimization​​

  • ​​Session Scalability​​: 55% faster session establishment rate (800,000/sec → 1.24M/sec) via improved ASIC scheduling
  • ​​Memory Management​​: Reduced NP7XLite cache misses during sustained 200Gbps DDoS mitigation
  • ​​BGP Convergence​​: Achieved 0.8-second route reconvergence for routing tables exceeding 25M entries

​​Operational Innovations​​

  1. ​​Network Slicing​​: Hardware-enforced segmentation for 5G SA core networks with 3GPP compliance
  2. ​​Smart NIC Integration​​: Full offloading compatibility with NVIDIA ConnectX-7 adapters (RoCEv2/RDMA)
  3. ​​Telemetry Analytics​​: Native integration with Splunk Enterprise 9.3+ for real-time threat visualization
