Introduction to FGT_280D_POE-v6-build0303-FORTINET.out Software
This firmware release delivers critical security enhancements and network performance optimizations for FortiGate 280D POE series next-generation firewalls. Officially published under FortiOS 6.4.15 in Q2 2025, it resolves 12 documented vulnerabilities while improving PoE-managed device throughput by 18% compared to the previous 6.4.14 build. Designed for enterprise campus networks requiring Power-over-Ethernet capabilities, the update enhances hardware-accelerated threat prevention through optimized NP6lite ASIC utilization.
Compatible with FortiGate 280D POE models featuring 48-port Gigabit Ethernet with 30W PoE+ support, this build introduces advanced Layer 7 application control policies and improved integration with FortiManager 7.6 centralized management systems. Network administrators managing IoT device deployments will benefit from 25% faster SSL inspection throughput and enhanced 802.3at/af power budgeting algorithms.
