1. Introduction to FGT_98D_POE-v6-build0231-FORTINET.out
This firmware package provides critical security enhancements for FortiGate 98D Power over Ethernet (PoE) series appliances running FortiOS 6.0. Designed for small business network deployments, build0231 addresses vulnerabilities in VPN services, PoE management subsystems, and web filtering components while maintaining backward compatibility with existing security policies.
The update targets FG-98D-POE hardware platforms manufactured between 2018-2022, extending operational security through FIPS 140-2 compliant cryptographic protocol upgrades. While official release notes remain accessible only through Fortinet’s partner portal, version sequencing aligns with the vendor’s Q2 2024 security patch cycle for extended-support devices.
