Aren't all Hue bulbs Zigbee? They have some WiFi or bluetooth models now I believe but afaik all of them support Zigbee with a bridge.

There was encryption for a while, iirc. This was removed, and you can now communicate directly with Hue bulbs.
You can also use bluetooth for hub-free operation directly from a phone.
