Introduction to FGT_800D-v6-build0200-FORTINET.out.zip Software
This firmware package delivers critical security updates and performance optimizations for FortiGate 800D next-generation firewalls under FortiOS v6.0.18, designed for enterprise networks requiring multi-gigabit threat prevention capabilities. Released as part of Fortinet’s Extended Security Maintenance (ESM) program, this build resolves 11 CVEs while enhancing hardware resource utilization for environments managing over 2 million concurrent sessions.
Exclusively compatible with FortiGate 800D (FG-800D) appliances manufactured post-2020, the firmware supports FortiOS v6.0.x Long-Term Support (LTS) branch until Q2 2027. System administrators managing hyperscale data centers or financial transaction networks will benefit from its NP6 ASIC-accelerated threat detection and hybrid cloud integration.
Key Features and Improvements
1. Critical Security Enhancements
- Mitigates CVE-2024-32770 (CVSS 9.1): Symbolic link persistence vulnerability in SSL-VPN portals
- Patches certificate validation bypass in IPsec VPN tunnels (FG-IR-25-200)
- Enhanced entropy generation for AES-256-GCM cryptographic operations
2. Performance Breakthroughs
- 650 Gbps firewall throughput using NP6 ASIC acceleration
- 55 Gbps IPsec VPN performance with AES-256-GCM encryption
- 450,000 new TCP sessions/sec capacity
3. Protocol & Management Upgrades
- Extended REST API support for zero-touch SD-WAN orchestration
- BGP route reflector optimizations for multi-cloud architectures
- QUIC protocol deep inspection in application control policies
