Yes in essence it secures/encrypts data on a hardware level. Anything newer than (I suppose) 8700k or 2700x should support it. Or there abouts.
IIUC, in the past a dedicated chip was needed to provide the same level of security but in recent years this functionality has been built into CPU's. Win11 now has mandatory software support.
At least that's how I understand it, but I'm happy to be corrected.
