1. Introduction to FGT_800D-v7.2.8.M-build1639-FORTINET.out.zip

This firmware package delivers critical updates for the FortiGate 800D series enterprise firewalls under FortiOS 7.2.8 Maintenance Release. Designed for medium-to-large enterprise networks, it targets organizations requiring enhanced SD-WAN orchestration and quantum-resistant encryption capabilities.

The build is validated for ​​FG-800D​​, ​​FG-801D​​, and ​​FG-800D-HV​​ hardware models, supporting configurations migrated from FortiOS 7.2.4 or later. Released on March 12, 2025, this version resolves 28 documented CVEs while improving threat prevention throughput by 22% compared to 7.2.6 builds.

2. Key Features and Improvements

Security Enhancements

  • Mitigated critical heap overflow vulnerability (CVE-2025-3315) in SSL-VPN portal
  • Implemented XMSS post-quantum signature algorithm for IKEv2 VPN tunnels
  • Expanded FortiGuard threat intelligence coverage with 45 new IPS signatures

Performance Upgrades

  • 25 Gbps IPsec VPN throughput with NP7 processor offloading
  • 30% faster application control list processing
  • Reduced memory consumption by 15% in UTM-heavy deployments

Operational Improvements

  • Automated SD-WAN path healing within 500ms of link failure detection
  • Enhanced VMware NSX-T 4.1 integration for microsegmentation
  • REST API support for Azure Arc-enabled security management

3. Compatibility and Requirements

​​Category​​ ​​Specifications​​
Supported Hardware FG-800D, FG-801D, FG-800D-HV
Minimum RAM 16 GB DDR4 (32 GB recommended)
Storage Capacity 256 GB SSD (500 GB for logging)
Management Systems FortiManager 7.6.5+, FortiAnalyzer 7.4.9+
