Once an organization encrypts data on third party servers, storage infrastructure and devices, it depends on centralized enterprise key management to generate, distribute, store, rotate, and revoke/destroy cryptographic keys associated with that encrypted data, wherever it resides.

Enterprise Key Management solutions from Thales, enable organizations to centrally manage and store cryptographic keys and policies for third-party devices including Microsoft SQL TDE, Oracle TDE, and KMIP-compliant encryption products. CipherTrust Enterprise Key Management delivers a robust, standards-based platform for managing encryption keys from disparate sources across the enterprise. It simplifies the administrative challenges around encryption key management to ensure that keys are secure and always provisioned to authorized encryption services.
