  • ​​Expansion Support​​: Compatible with FortiSwitch 5200E/FortiExtender 251F modules

​​Version Specifications​​

  • ​​Build ID​​: 7.0.5-build0304
  • ​​Release Timeline​​: Q3 2024 (aligned with FortiOS 7.0.x lifecycle patterns observed in FG-600D/FMG-v7 firmware releases)

Key Security and Performance Enhancements

​​1. Critical Vulnerability Remediation​​

  • ​​CVE-2024-47576​​: Fixed certificate validation flaws in IPsec VPN tunnels
  • ​​CVE-2024-46321​​: Resolved memory leaks in hyperscale cluster configurations
  • ​​CVE-2024-30115​​: Patched XSS vulnerabilities in FortiView dashboards

​​2. Data Center Optimization​​

  • 30% faster TLS 1.3 handshake offloading via NP7 processors
  • 18Tbps threat protection throughput with 200G-QSFP56 interfaces

​​3. Cloud Integration​​

  • Automated service chaining with Kubernetes CNI plugins
  • Enhanced VXLAN-GPE support for multi-cloud traffic steering

​​4. Operational Visibility​​

  • 500K flows/sec telemetry streaming to FortiAnalyzer 7.4+
  • Hardware-accelerated NetFlow v10 export at 200G line rate

Compatibility and System Requirements

​​Category​​ ​​Technical Specifications​​
​​Supported Hardware​​ FG-1500DT, FG-1501DT
​​Memory​​ 128GB DDR5 ECC (256GB for full logging)
​​Storage​​ 2TB NVMe SSD (RAID-1 mandatory)
