Data enclave is a secure and isolated area in which sensitive data is stored and managed. It is a secure environment that is used to protect an organization's most sensitive data and ensure that it is not accessed by unauthorized personnel. Data enclaves can include physical, logical, and cloud-based solutions that provide encryption, authentication, and access control mechanisms to protect data. Data enclaves are used to ensure that only authorized personnel have access to the data and that the data is secure from potential cyber threats.
