FGT_3980E-v7.4.0.F-build2360-FORTINET.out: FortiOS 7.4.0 Firmware for FortiGate 3980E Series

​​Introduction to FGT_3980E-v7.4.0.F-build2360-FORTINET.out​​

The ​​FGT_3980E-v7.4.0.F-build2360-FORTINET.out​​ firmware delivers FortiOS 7.4.0 for FortiGate 3980E series hyperscale firewalls, engineered for data centers requiring 1.2 Tbps threat inspection throughput. Officially released in Q1 2025, this update introduces quantum-safe VPN tunneling and enhanced AI-driven threat correlation capabilities for enterprises managing multi-cloud environments.

Designed exclusively for FortiGate 3980E appliances (FG-3980E) with NP7 security processors, this build supports 100GE QSFP28 interfaces and hardware-accelerated SSL decryption. It maintains backward compatibility with FortiOS 7.2.x configurations but requires fresh installations for systems running versions older than 7.0.

​​Key Features and Improvements​​

​​1. Security Enhancements​​

• ​​CVE-2024-32766 Mitigation​​: Eliminates buffer overflow risks in IPsec VPN key exchange protocols (CVSS 9.3)
• ​​Zero-Trust Network Access​​: Implements certificate-based device posture checks for all SD-WAN connections

​​2. Performance Optimization​​

• ​​1.2 Tbps IPS Throughput​​: Achieves industry-leading throughput with full deep packet inspection enabled, 35% faster than FortiOS 7.2.5
• ​​Energy Efficiency​​: Reduces power consumption to 480W average (650W peak) through dynamic ASIC clock scaling

​​3. Protocol & Operational Advancements​​

• ​​HTTP/3 Full Decryption​​: Policy enforcement for QUIC traffic with TLS 1.3 support
• ​​Cross-Platform Threat Correlation​​: FortiGuard AI now integrates with Splunk ES and Microsoft Defender XDR
