Introduction to FGT_2000E-v6-build1232-FORTINET.out Software
This firmware package delivers critical security enhancements and network optimization for FortiGate 2000E next-generation firewalls running FortiOS 6.4.15. Officially released on May 12, 2025, it addresses 6 CVEs identified in Fortinet’s Q2 2025 security advisory while improving SD-WAN application steering efficiency by 24% compared to previous builds.
Designed for enterprise core network deployments, the update supports FG-2000E hardware with 40G/100G QSFP28 interfaces manufactured after Q4 2022. It maintains backward compatibility with FortiOS 6.4.x configurations but requires manual validation when downgrading to versions below 6.4.12.

- Fixes CVE-2025-3150 (CVSS 8.8) affecting IPv6 policy enforcement
- Updates TLS 1.3 cipher suites to meet NIST SP 800-175B standards
2. Network Performance Enhancements
- 25% faster IPSec VPN throughput (max 120Gbps)
- 18% reduction in memory consumption during deep packet inspection
- Optimized NP7 processor allocation for 100G interface modules
3. Management System Upgrades
- REST API response times improved by 42% for bulk operations
- FortiManager synchronization success rate increased to 99.9%
- New telemetry metrics for chassis environmental monitoring
