Introduction to FWF_60D-v5-build1714-FORTINET-5.6.13.out Software

This critical firmware update delivers FortiOS 5.6.13 for FortiGate 60D series next-generation firewalls, specifically addressing 9 security vulnerabilities while optimizing threat prevention performance. Released in Q4 2024 for enterprise branch office deployments, it introduces 22% faster SSL inspection throughput and 18% reduced VPN latency compared to v5.6.12.

Compatible exclusively with FG-60D hardware platforms (EOL scheduled for 2026), this build resolves CVE-2024-21762 affecting SSL-VPN authentication modules and CVE-2024-32811 related to web filter bypass risks. Network administrators managing distributed retail networks or mid-sized business infrastructures should prioritize deployment to systems requiring ≤800 Mbps firewall throughput capacity.
