Introduction to FGT_3980E-v6-build0268-FORTINET.out Software

This firmware release delivers critical security updates and hyperscale optimization for FortiGate 3980E series next-generation firewalls, designed for enterprise data centers requiring 100Gbps+ threat inspection capabilities. Validated through Fortinet’s enterprise-grade QA process on March 28, 2025, build 0268 resolves 18 CVEs while enhancing NP7 security processor utilization in software-defined networking environments.

The update targets FG-3980E chassis systems running FortiOS 6.4.11 through 6.4.16, maintaining backward compatibility with existing VDOM configurations and fabric automation templates. This maintenance release focuses on improving TLS 1.3 inspection efficiency and cross-platform management integration.

Key Features and Improvements

  1. ​​Hyperscale Threat Prevention​​

    • Patched TLS 1.3 post-handshake authentication vulnerability (CVE-2025-4192) affecting encrypted traffic analysis
    • Updated intrusion prevention signatures (v24.9) targeting cloud-native attack patterns

  2. ​​Network Infrastructure​​

    • Increased VXLAN throughput by 35% through NP7 hardware acceleration optimizations
    • Reduced memory fragmentation in multi-tenant configurations by 82MB

  3. ​​Automation Enhancements​​

    • Added 12 new REST API endpoints for fabric connector orchestration templates
    • Improved FortiManager synchronization success rate to 99.92% during bulk deployments

  4. ​​System Resilience​​

    • Extended thermal tolerance for continuous 55°C ambient operation
    • Fixed buffer overflow in 100G QSFP28 interfaces under sustained 85Gbps traffic

Compatibility and Requirements

Component Specification
Hardware Models FortiGate 3980E (FG-3980E)
Minimum RAM 128 GB DDR4
Storage 1 TB NVMe SSD (RAID-10)
FortiOS Baseline 6.4.11+
