And I only found out after starting to manually block connections with a firewall... Authentec's TrueSuite became a must-install for some reason if you want to use their drivers and device on Windows.
One connection is for the software updates, and there are 2 other that I have no idea what they're used for. The TrueSuite app has an app store link and the features to export and import the fingerprint scans... So much for security...
