1. Introduction to FGT_2000E-v6-build1263-FORTINET.out

This firmware release delivers critical security updates and performance enhancements for FortiGate 2000E series next-generation firewalls, designed for enterprise networks requiring high-throughput threat prevention. As part of FortiOS 6.2 architecture, it resolves 9 CVEs identified in Fortinet’s Q4 2024 security advisories while maintaining compatibility with existing SD-WAN and VPN configurations.

Specifically optimized for hyperscale data center deployments, this build supports hardware-accelerated security services up to 250 Gbps firewall throughput. It is exclusively compatible with FortiGate 2000E hardware variants (FG-2000E, FG-2000E-SXM) requiring minimum 32GB RAM and FortiOS 6.0.6+ baseline installations.
