Introduction to FGT_3000D-v6-build1175-FORTINET.out.zip
This firmware package delivers FortiOS 6.4.12 – a critical security and performance update for FortiGate 3000D series enterprise firewalls. Released under Fortinet’s Q3 2025 security maintenance cycle, build1175 addresses 16 CVEs while optimizing threat detection capabilities for hyperscale network infrastructures.
Designed exclusively for FortiGate 3000D hardware platforms (FG-3000D/FG-3000DF models), this update maintains backward compatibility with existing FortiOS 6.4.x configurations. Data center operators requiring compliance with PCI-DSS 4.0 and NIST 800-53 standards will benefit from its enhanced SSL/TLS 1.3 inspection engine and memory leak remediation observed in high-availability clusters.
