​​Introduction to FGT_3301E-v7.4.0.F-build2360-FORTINET.out​​

This firmware package delivers FortiOS 7.4.0 for FortiGate 3301E Next-Generation Firewalls, officially released on October 15, 2024. Designed for enterprise data centers and high-density network environments, it resolves 18 critical CVEs while improving threat inspection throughput by 25% compared to FortiOS 7.2.5. The update supports 15 Gbps SSL inspection capacity and 1.8 million concurrent connections, making it essential for organizations requiring FISMA High compliance and zero-trust network architecture implementations.

The 3301E model now integrates with FortiManager 7.4.2 for centralized policy orchestration and features NP6XLite-accelerated TLS 1.3 decryption, achieving 95% line-rate performance for encrypted traffic analysis.
