Introduction to FGT_60E-v6-build1263-FORTINET.out Software

This firmware update delivers critical security enhancements and operational optimizations for FortiGate 60E series next-generation firewalls. Released in Q1 2025, build 1263 addresses 6 CVEs rated medium-to-critical severity while maintaining backward compatibility with existing network configurations. Designed for small-to-medium enterprises, the FortiGate 60E appliance supports up to 2 Gbps firewall throughput with integrated SD-WAN capabilities.

The update specifically targets vulnerabilities in SSL/TLS inspection modules while improving interoperability with FortiManager 6.2+ centralized management systems. Compatible with both standalone and HA cluster deployments, it aligns with NIST SP 800-193 firmware integrity requirements for federal contractors.
