Introduction to vsigupdate-OS6.2.0_91.09581.MMDB.pkg

This critical infrastructure update (build 09581) delivers Fortinet’s latest geolocation intelligence database for FortiOS 6.2.0, containing 1.28 million new IP-to-location mappings validated through FortiGuard Labs’ global threat intelligence network. Released on May 12, 2025, it addresses emerging gaps in regional traffic analysis capabilities while introducing enhanced protocol support for 5G mobile carrier networks.

The package supports FortiGate 60E/80E/100F series appliances and FortiWiFi 90G/91G devices running FortiOS 6.2.0 or newer. This revision resolves 15 cases of obsolete country-code mappings reported in Q1 2025 and improves detection accuracy for satellite-based internet providers by 37%.
