There is PrivateCore vCage. Couldn’t find much information at their website. Seems like a commercial product. Would wonder about the prices out of curiosity.
Are there any other competition products? Or even Libre Software / Open Source ones?
The closest similar thing for Linux seems to be TREZOR but that only keeps the full disk encryption password in the CPU registers and doesn’t encrypt the full RAM contents?
