​​Introduction to FGT_601E-v7.4.0.F-build2360-FORTINET.out​​

This firmware package delivers FortiOS 7.4.0 for FortiGate 601E Next-Generation Firewalls, released on March 10, 2025. Designed for enterprise branch offices and mid-sized networks, it resolves 14 critical CVEs while improving threat prevention throughput by 18% compared to FortiOS 7.2.4. The update supports 5 Gbps SSL inspection capacity with 200,000 concurrent connections, making it essential for organizations requiring PCI-DSS 4.0 compliance and zero-trust network implementations.

The 601E series now integrates with FortiManager 7.6.7 for centralized policy orchestration and features NP6Lite-accelerated TLS 1.3 decryption, achieving 92% line-rate performance for encrypted traffic analysis.
