It was touted as making cloud computing secure. How anyone could actually believe this is beyond me. The cloud provider has physical access to the host machine. For all I know it could all be smokes and mirrors, emulated on a C64, while all my data is getting exfiltrated. The only people who ever bought into this is cryptobro crackheads and government contractors doing it for compliance bullshit. Up to 0% of cloud customers went as far as to even try to verify the thing does what it says it does.
