Why confidential computing is essential for enterprise AI

As enterprises push AI into sensitive domains (healthcare, finance, government), protecting data during processing — not just at rest or in transit — is shifting from a nice-to-have security feature to a prerequisite for deployment. HPE and NVIDIA are positioning confidential computing as foundational infrastructure for sovereign AI.
