Introduction to FGT_3500F-v7.2.3.F-build1262-FORTINET.out
This enterprise-grade firmware delivers FortiOS 7.2.3 Feature Release (build 1262) for FortiGate 3500F Series hyperscale firewalls, designed for carrier-grade networks and large enterprise data centers requiring multi-terabit security performance. Released in Q4 2024 through Fortinet’s Security Fabric Update Program, it addresses 16 critical vulnerabilities while introducing hardware-specific optimizations for the 3500F’s NP7XLite security processors.
Key specifications include:
- 2.4 Tbps firewall throughput
- 1.5 Tbps SSL inspection capacity
- 5 million concurrent sessions
The build implements security enhancements from FortiGuard Labs’ Q3 2024 threat intelligence, including advanced ICS protocol protections and AI-driven traffic pattern analysis. It maintains backward compatibility with FortiOS 7.2.x configurations while optimizing performance for hyperscale environments.
Key Technical Enhancements
1. Hyperscale Security Architecture
