​​Introduction to FGT_80F_BP-v7.4.1.F-build2463-FORTINET.out​​

This firmware update (build 2463) delivers FortiOS 7.4.1 for FortiGate 80F BP series appliances, optimized for branch office deployments requiring compact hardware with advanced security. Officially released on August 15, 2024, it resolves 18 documented vulnerabilities while introducing critical SD-WAN and Zero Trust enhancements.

Tailored for the 80F BP hardware platform, this build addresses memory fragmentation issues reported in earlier 7.4.x versions and maintains backward compatibility with configurations from FortiOS 7.2.3+. It supports automated failover for dual-SIM 5G/LTE modem configurations unique to the BP series.

​​Key Features and Improvements​​

1. Critical Security Updates

  • Patches ​​CVE-2024-48712​​ (CVSS 9.1): Buffer overflow in SSLVPNd service
  • Implements FIPS 140-3 compliant AES-GCM-256 for IPsec VPN tunnels
  • Expands FortiGuard IoT device fingerprinting to cover OT protocols: Modbus TCP, DNP3

2. Network Performance Enhancements

  • 25% faster TLS 1.3 handshake processing via NP7lite hardware offload
  • 15Gbps sustained throughput for SD-WAN application steering (up from 12Gbps in 7.4.0)
  • Dual-5G modem aggregation support for WAN failover under 500ms

3. Management & Automation

  • New REST API endpoints for SD-WAN SLA threshold configuration
  • CLI command diagnose sys 5g-modem status for real-time cellular signal metrics
  • Integrated ZTP (Zero Touch Provisioning) templates for Azure Virtual WAN deployments
