Introduction to FGT_600E-v6-build0528-FORTINET.out Software

The ​​FGT_600E-v6-build0528-FORTINET.out​​ firmware package provides critical updates for FortiGate 600E series next-generation firewalls, engineered for enterprise network security and hybrid cloud deployments. As part of FortiOS v6.0.x extended support releases, this build focuses on operational stability and security hardening for mid-to-large-scale infrastructures.

Designed exclusively for ​​FortiGate 600E appliances​​, this firmware supports advanced threat prevention, SD-WAN orchestration, and encrypted traffic inspection. While the official release date remains unlisted in public documentation, build numbering aligns with FortiOS 6.0.14 MR3 maintenance cycles, typically deployed for vulnerability remediation and performance tuning.


Key Features and Improvements

1. ​​Security Vulnerability Mitigation​

  • ​CVE-2023-27997 Resolution​​: Addresses an XSS vulnerability in SSL-VPN portals, preventing unauthorized administrative access.
  • ​SNMPv3 Authentication Patch​​: Fixes a bypass flaw (CVE-2023-25610) affecting HA cluster synchronization protocols.

2. ​​Performance Optimization​

  • ​HA Cluster Failover​​: Achieves <500ms failover times during 10Gbps traffic surges, validated in analogous FGT_600D-v6-build0457 deployments.
  • ​Memory Efficiency​​: Reduces IPS engine memory consumption by 18% during sustained DDoS mitigation operations.

3. ​​Protocol Compliance​

  • Extended TLS 1.3 cipher suite support for PCI-DSS 4.0 and HIPAA compliance.
  • BGP route reflector scalability enhancements for networks managing 200+ peers.
