Introduction to FGT_600E-v7.2.3.F-build1262-FORTINET.out.zip

This firmware update delivers FortiOS 7.2.3.F-build1262 for FortiGate 600E next-generation firewalls, designed to address critical security vulnerabilities while enhancing enterprise network performance. Released under Fortinet’s Q1 2025 security update cycle, the package specifically targets organizations requiring 20Gbps+ threat-protected throughput with full SSL inspection capabilities.

Exclusively compatible with FortiGate 600E hardware (FG-600E models), this February 2025 release resolves 5 CVEs documented in Fortinet’s January 2025 security advisory (FG-IR-25-087). The build integrates enhanced NP6lite security processor optimizations and improves SD-WAN orchestration functionality.
