Introduction to FGT_800D-v7.2.3.F-build1262-FORTINET.out

This firmware package delivers critical security updates and operational optimizations for FortiGate 800D next-generation firewalls operating on FortiOS 7.2.3. Released under Fortinet’s Q1 2025 Security Advisory Program, it addresses 12 CVEs rated high/critical severity while enhancing threat prevention capabilities for enterprise network environments.

Designed specifically for the 800D hardware platform with FortiASIC NP6 acceleration, build 1262 introduces advanced traffic inspection algorithms optimized for 40GE/100GE interfaces and improves Zero Trust Network Access (ZTNA) session stability under high-concurrency conditions (30,000+ concurrent connections). The update maintains backward compatibility with FortiOS 7.2.x configurations, making it essential for organizations managing medium-to-large enterprise network infrastructures.
