​​Introduction to FGT_2000E-v6-build1966-FORTINET.out Software​​

The ​​FGT_2000E-v6-build1966-FORTINET.out​​ firmware represents a critical infrastructure upgrade for Fortinet’s enterprise-grade FortiGate 2000E next-generation firewall series. Released under FortiOS v6.4 architecture, this build addresses 9 CVEs while optimizing network stability for hyperscale data center deployments. Designed for organizations requiring carrier-class threat prevention, it enhances hardware resource allocation through NP6 ASIC acceleration and improves SSL/TLS 1.3 enforcement for financial sector compliance.

Compatible exclusively with ​​FortiGate 2000E chassis systems​​ (FG-2000E), this firmware resolves authentication bypass risks (CVE-2023-27997) and improves IPsec VPN cluster synchronization. Released in Q4 2023 as part of Fortinet’s Extended Security Maintenance cycle, it remains essential for organizations maintaining 100Gbps+ inspection throughput requirements.

​​Key Features and Improvements​​

​​1. Critical Security Patches​​

  • ​​CVE-2023-27997 Remediation​​: Eliminates SSL-VPN heap overflow vulnerabilities (CVSS 9.8) affecting FortiOS 6.0-6.4 versions
  • ​​FortiGuard IPS Expansion​​: Adds 31 new signatures targeting APT41 and Clop ransomware command-and-control patterns

​​2. Performance Enhancements​​

  • ​​Throughput Optimization​​: Achieves 98 Gbps firewall throughput (19% improvement over v6.4.5) with concurrent UTM services enabled
  • ​​Cluster Synchronization​​: Reduces HA failover time to 800ms (42% faster than v6.4.6 builds)

​​3. Protocol & Compliance Updates​​

  • ​​TLS 1.3 Full Enforcement​​: Mandates modern encryption for all SSL-VPN and web proxy traffic flows
  • ​​FIPS 140-2 Validation​​: Maintains compliance for US federal agency deployments requiring FIPS-approved cryptographic modules

​​Compatibility and Requirements​​

​​Supported Hardware​​ ​​Minimum OS Version​​ ​​Storage Requirement​​ ​​Release Date​​
FortiGate 2000E (FG-2000E) FortiOS 6.4.0 6.4 GB October 12, 2023
FortiSwitch 324E-POE FortiSwitchOS 6.4.9 N/A N/A

​​Critical Compatibility Notes​​:

  • Incompatible with FortiGate 1800F/2500E models due to NP7 ASIC architecture differences
  • Requires manual session table migration when upgrading from v5.6.x configurations

​​Limitations and Restrictions​​

  1. ​​Performance Constraints​​
  • Maximum 72 Gbps throughput when SSL deep inspection and application control enabled concurrently
  • HA clusters limited to 4 nodes (vs. 8-node support in v7.x firmware)
  1. ​​Protocol Support​​
  • No QUIC protocol inspection capabilities
  • TLS 1.3 session tickets restricted to 12-hour validity periods
