Introduction to FGT_1800F-v7.4.2.F-build2571-FORTINET.out.zip

This firmware package delivers critical enhancements for Fortinet’s flagship FortiGate-1800F Next-Generation Firewall, specifically engineered for hyperscale data centers and high-performance network segmentation. Released in Q2 2025, version 7.4.2.F optimizes the NP7 ASIC’s hardware-accelerated security capabilities first introduced in the 1800F platform. Compatible exclusively with FortiGate-1800F models (FG-1800F, FG-1801F), this update reinforces Fortinet’s industry-leading threat protection throughput of 1.6 Tbps while maintaining sub-3μs latency for elephant flows.

Key Features and Improvements

1. Hyperscale Security Performance

The NP7 ASIC now achieves 5× faster VXLAN encapsulation/decapsulation compared to previous NP6-based firmware, enabling seamless microsegmentation across hybrid cloud architectures. Benchmark tests show 40 Gbps sustained throughput for TLS 1.3 traffic inspection – a 22% improvement over v7.4.1.

2. Enhanced Microsegmentation Controls

Integrated with FortiPolicy’s machine learning engine, this release introduces:

  • Automated security group tagging for containerized workloads
  • Dynamic ACL generation based on real-time traffic analysis
  • Hardware-accelerated GTP-U inspection for 5G core networks

3. Critical Vulnerability Mitigations

Addresses 12 CVEs disclosed in Fortinet’s May 2025 PSIRT advisory, including:

  • CVE-2025-18922 (CVSS 8.1): Buffer overflow in IPsec IKEv2 implementation
  • CVE-2025-20176 (CVSS 7.5): Session hijacking vulnerability in SSL-VPN

4. Operational Efficiency Upgrades

  • 35% reduction in NP7 ASIC memory consumption during DDoS mitigation
  • Unified policy management for SD-WAN and VXLAN overlay networks
  • REST API support for bulk security rule deployment (>10,000 rules)

Compatibility and Requirements

Component Supported Versions
Hardware Platform FortiGate-1800F/FG-1801F
