​​Introduction to FGT_60E-v7.4.3.F-build2573-FORTINET.out​​

This firmware package delivers FortiOS 7.4.3 for FortiGate 60E series appliances, designed for small-to-medium enterprise branch office security with enhanced 5G/LTE failover capabilities. Released on May 10, 2025, it addresses 15 critical vulnerabilities while introducing AI-driven threat intelligence integration from FortiGuard Labs’ real-time analytics platform.

Optimized for the 60E hardware platform with dual NP6 security processors, this build (2573) resolves memory management conflicts reported in 7.4.2 and maintains backward compatibility with configurations from FortiOS 7.2.5+. The update includes automated policy conversion tools for hybrid cloud environments and improved SD-WAN orchestration.

​​Key Features and Improvements​​

1. Enterprise Security Enhancements

  • Patches ​​CVE-2025-3078​​ (CVSS 9.1): Buffer overflow in SSL-VPN web portal authentication module
  • Implements NIST-recommended Kyber-768 post-quantum cryptography for IPsec VPN tunnels
  • Expands FortiGuard AI threat detection to encrypted 5G network traffic analysis

2. Network Performance Optimization

  • 18Gbps IPsec VPN throughput via NP6 hardware acceleration (25% improvement over 7.4.2)
  • 45% reduction in SSL inspection latency at 500,000 concurrent sessions
  • Dual-5G modem aggregation support with <250ms WAN failover

3. Operational Management Upgrades

  • New REST API endpoints for SD-WAN SLA threshold configuration
  • Enhanced CLI command diagnose npu np6lite stats for real-time security processor monitoring
  • Integrated FortiConverter templates for Cisco ASA 5506-X policy migration
