MongoDB's field-level encryption (FLE) capability pairs with Vault's KMIP secrets engine to provide strong privacy and security controls for organizations. FLE allows developers to selectively encrypt specific data fields, protecting sensitive information and enhancing communication between client apps and server. By pairing an FTE-capable database with a KMIP provider, the highest level of security and control is achieved. MongoDB's FLE features include protection for data in transit, at rest, and in use, making data unreadable to those running the database, and simplifying enforcement of right-to-erasure mandates. The example FLE flow with a KMIP provider demonstrates how MongoDB and HashiCorp Vault can benefit organizations with security management across their databases and applications.
