Introduction to FGT_3960E-v6-build1879-FORTINET.out
This firmware package delivers critical security updates and performance enhancements for FortiGate 3960E series next-generation firewalls, designed for enterprise data centers requiring 100Gbps+ threat protection throughput. Released under FortiOS 6.4.6 framework in Q1 2025, build 1879 addresses 9 CVEs while optimizing hardware resource allocation for hyperscale network environments.
Key deployment scenarios include:
- Data Center Security: Mitigates advanced persistent threats targeting high-throughput networks
- Hardware Optimization: Enhances NP7 security processor efficiency for SSL/TLS inspection
- Compatibility: Maintains interoperability with FortiManager 7.4+ and FortiAnalyzer 7.2+
Key Features and Improvements
1. Critical Security Updates
- CVE-2025-32801 Remediation: Patches HTTP/2 protocol vulnerability enabling DDoS amplification (CVSS 9.3)
- CVE-2024-47575 Fix: Eliminates authentication bypass risks in HA cluster synchronization
- Hardware-rooted firmware verification using ECDSA-384 cryptographic signatures
2. Performance Enhancements
- 25% faster IPsec VPN throughput (120 Gbps → 150 Gbps)
- 40% memory optimization for deep packet inspection engines
- Dynamic workload balancing across NP7 processors
3. Enterprise-Grade Protocol Support
- Extended BGP EVPN support for multi-tenant cloud environments
- Improved VXLAN routing scalability (10,000+ tunnels)
- TLS 1.3 post-quantum cryptography trial support
