Introduction to FGT_500D-v6-build0200-FORTINET.out

This firmware package delivers critical security updates and operational enhancements for FortiGate 500D series next-generation firewalls running FortiOS 6.x. Released under Fortinet’s Q1 2025 Extended Security Maintenance cycle, build 0200 addresses 9 CVEs while improving threat detection efficiency by 22% compared to previous 6.0.x versions.

Compatible with FortiGate 500D and 500DF models, this update supports hybrid mesh firewall configurations and maintains backward compatibility with existing SD-WAN/ZTNA policies. The firmware aligns with NIST SP 800-193 guidelines for resilient security architectures, making it suitable for enterprise networks requiring FIPS 140-3 validated cryptography.
