Introduction to FGT_600E-v7.2.2.F-build1255-FORTINET.out

This firmware package delivers FortiOS 7.2.2 for ​​FortiGate 600E​​ enterprise firewalls, addressing critical vulnerabilities while enhancing network performance. Released in ​​Q2 2025​​, build 1255 resolves 14+ security advisories documented in Fortinet’s April 2025 Security Bulletin. Designed for high-traffic environments like data centers and cloud gateways, this update improves threat detection accuracy and operational efficiency for organizations complying with PCI-DSS 4.0 and HIPAA standards.

Exclusively compatible with FortiGate 600E hardware, the firmware requires existing FortiOS 7.2.x installations. Administrators managing HA clusters must synchronize this update across all nodes within 24 hours to prevent configuration mismatches.

Key Features and Technical Enhancements
