What Is Confidential AI? The Security Gap Your Encryption Doesn’t Cover

Your data is encrypted at rest. Encrypted in transit. But the moment an AI model processes it, everything sits exposed in memory. IBM’s 2025 Cost of a Data Breach Report found that 13% of organizations experienced breaches of AI models or applications. Of those compromised, 97% lacked proper AI access controls. Healthcare breaches averaged $7.42 million per incident , taking 279 days to identify and contain. Over 70% of enterprise AI workloads will involve sensitive data by 2026. Yet most organizations protect that data everywhere except where it matters most: during actual computation. Confidential AI fixes this. What Is Confidential AI? Confidential AI uses hardware-based isolation to protect data and models while they’re being processed. Not before. Not after. During. The core technology is called a Trusted Execution Environment, or TEE. Think of it as a vault built directly into the CPU or GPU. Data enters encrypted, gets processed inside the vault, and leaves encrypted. The operat
