A Data Vault is a system that isolates and secures sensitive data by encrypting it at the application level, using access controls, audit logs, and other security measures to limit exposure and unauthorized access. Enterprise Key Management (EKM) is a system used by organizations to control and protect the encryption keys that secure their sensitive data. EKM helps manage these keys securely, ensuring only authorized users or systems can use them, and rotating them regularly to reduce the risk of being compromised. A Data Vault typically integrates with EKM to control and secure the encryption keys, ensuring that the sensitive data it holds is protected at all times. The integration allows for cryptographic isolation of the data, getting access to a single encryption key will only allow a subset of the data to be decrypted.
