Introduction to FGT_500D-v6-build1066-FORTINET.out.zip Software
The FGT_500D-v6-build1066-FORTINET.out.zip firmware package delivers FortiOS 6.4.5 for FortiGate 500D enterprise firewalls, designed to address critical vulnerabilities while optimizing network performance for high-traffic environments. Released under Fortinet’s Q3 2024 Extended Security Support (ESS) program, this build targets organizations requiring stable operations in carrier-grade and data center deployments.
Compatible exclusively with FortiGate 500D series appliances, this update resolves 15 documented CVEs from Fortinet’s 2024 Security Advisories, including exploits targeting SSL-VPN portals and administrative interfaces. Enterprises operating under NIST 800-53 or ISO 27001 frameworks will benefit from its enhanced cryptographic validation and session auditing capabilities.
