Introduction to FGT_140D-v6-build1190-FORTINET.out

This firmware update delivers essential security patches and performance enhancements for FortiGate 140D series firewalls, specifically engineered for mid-sized enterprise network security. As part of FortiOS 6.4.11 maintenance release (build 1190), it addresses 8 critical CVEs identified in Q1 2025 while maintaining backward compatibility with hybrid network architectures.

Optimized for FG-140D appliances running FortiOS 6.4.x, this build enhances threat protection throughput up to 25 Gbps with active UTM services. Official release notes confirm interoperability with FortiManager 7.2.3+ for centralized policy orchestration and audit logging.
