​​Introduction to FGT_3700D-v7.4.0.F-build2360-FORTINET.out​​

This firmware package delivers FortiOS 7.4.0 for FortiGate 3700D next-generation firewalls, specifically engineered for hyperscale data center deployments requiring NIST 800-207 zero-trust compliance. Released in Q4 2024, build 2360 introduces hardware-accelerated threat prevention capabilities via Fortinet’s NP7 ASIC architecture, achieving 3.6x faster SSL inspection throughput compared to previous versions.

Designed exclusively for ​​FortiGate 3700D​​ chassis systems, this update supports 400G QSFP-DD interfaces and integrates with FortiManager 7.4.6 for centralized policy management. The firmware aligns with FIPS 140-3 Level 4 validation requirements, making it ideal for government agencies and financial institutions handling sensitive data.
