Introduction to FGT_800D-v6-build0419-FORTINET.out Software

This enterprise-grade firmware update enhances network security for FortiGate 800D Next-Generation Firewalls, designed for high-performance data center deployments requiring 100Gbps+ threat inspection capabilities. Released under FortiOS 6.4.19 in Q2 2025, the build resolves 19 critical CVEs including vulnerabilities in SSL/TLS 1.3 session resumption protocols and IPv6 fragment reassembly handling.

Optimized for the FG-800D chassis platform, this version introduces hardware-accelerated deep packet inspection through NP7 ASICs while maintaining FIPS 140-3 Level 3 compliance. Network architects managing hyperscale environments will benefit from improved VXLAN gateway performance and automated policy synchronization with FortiManager 7.8+ management systems.

Key Features and Improvements

​​1. Hyperscale Security Enhancements​​

  • Mitigates CVE-2025-31811 (SSL-VPN credential caching vulnerability)
  • Addresses CVE-2025-32918 (IPSec IKEv2 cryptographic weakness)
  • Expands FortiGuard IPS coverage to 228 new APT attack signatures

​​2. Data Center Performance​​

  • Boosts SSL inspection throughput by 40% via NP7 ASIC optimization
  • Reduces VXLAN encapsulation latency to <5μs per packet
  • Supports 8 million concurrent sessions per chassis module

​​3. Cloud Integration​​

  • Enables native AWS Gateway Load Balancer health monitoring
  • Adds Azure Virtual WAN BGP route analytics integration
  • Supports Google Cloud Interconnect MTU auto-configuration

​​4. Operational Efficiency​​

  • Improves HA cluster synchronization speed to 200ms failover
  • Enhances log compression ratio to 5:1 for long-term retention
  • Fixes SNMPv3 authentication failures in multi-VDOM setups

Compatibility and Requirements

​​Component​​ ​​Specification​​
Supported Hardware FortiGate 800D (FG-800D)
FortiOS Base Version 6.4.15+
Management Systems FortiManager 7.8.3+, FortiAnalyzer 7.6.4+
