Introduction to FGT_60E-v5-build6225-FORTINET-5.4.5.out Software
This firmware update delivers FortiOS 5.4.5 for FortiGate 60E network security appliances, addressing critical vulnerabilities while maintaining operational stability for legacy deployments. Released on October 15, 2024, under extended vendor support, build 6225 serves as the final maintenance update for the FortiOS 5.4 branch, offering enterprises a secure migration path to newer firmware versions.
Designed specifically for the FortiGate 60E hardware platform, this release focuses on hardening SSL-VPN security and optimizing threat prevention workflows. As a mature firmware version, it supports hybrid environments where newer FortiOS branches cannot yet be deployed due to compatibility constraints with legacy network infrastructure.
