The security blind spot nobody liked to mention.
Most enterprise teams assume their cloud workloads are fully encrypted, and they are, across two distinct states.
One, data at rest stored on encrypted disks or in object stores.
Two, data in transit moving across networks via encrypted transport protocols.
The vulnerability lives in the third state, data in use.
To execute an application, a CPU must load unencrypted plaintext into system memory RAM.
In a conventional shared host environment, any process with privileged host access, a hypervisor exploit, a misconfigured host agent, or a rogue administrator can potentially read or alter that working memory.
For a decade, enterprises accepted a contractual promise.
The cloud vendor guarantees via legal terms and SOC two audits that their operators will not peek.
For web applications or standard internal tools, that contract is usually fine.
For regulated data, proprietary AI models, and intellectual property, however, compliance auditors and risk officers are increasingly saying that contractual promises are no longer enough.
They want cryptographic proof.
