Which Security Guardium Data Encryption products fit your organization?
Guardium® for File and Database Encryption
Address compliance reporting while protecting structured databases, unstructured files and cloud storage services through encryption of data-at-rest with centralized key management, privileged user access control and detailed data access audit logging.
Guardium® for Cloud Key Management
Centralize key management for reduced complexity and operational costs with full lifecycle control of encryption keys, including automated key rotation and expiration management. Bring your own key (BYOK) customer key control allows for the separation, creation, ownership and revocation of encryption keys or tenant secrets used to create them.
Guardium® for Data Encryption Key Management
Centralize key management for Guardium solutions as well as third party devices, databases, cloud services and applications. Support for KMIP—an industry-standard protocol for encryption key exchange—makes it possible for keys to be managed with a common set of policies.
Guardium® for Batch Data Transformation
Enable large-quantity static data masking, which transforms selected data to unreadable forms in order to utilize data sets while preventing misuse of sensitive data. Mask data to share with third parties, before adding to a big data environment, to prepare for safe cloud migration, and more.
Homomorphic Encryption Services
Fully homomorphic encryption (FHE) allows you to compute on sensitive or regulated data while the data itself remains encrypted. With IBM Security® Homomorphic Encryption Services, you can confidently process and collaborate on encrypted data while preserving privacy.

Frequently asked questions
Get answers to common questions
What is encryption?
Encryption is the process that scrambles readable text so it can only be read by a person who has access to the encryption key.
Why is data encryption important?
Encryption helps protect private information and other sensitive data, whether the host is online or offline, and even in the event of a breach. As long as the encryption key is secured, the
encrypted data remains protected against unauthorized users.
How do encryption keys work?
Encryption keys are used by the encryption algorithm to “lock” the data during an encoding process such that the data cannot be “unlocked” without access to the encryption key. Encryption keys
are generally kept private. Proper key management is a key factor in keeping your data secure.
Why is encryption key management important?
The loss of any one key can mean that the data it protects will also be lost. It is important to track, manage and protect keys from accidental loss or compromise. Fortunately, GDE automates and
manages the entire encryption key lifecycle.
What is tokenization?
Tokenization is a form of data protection that retains the same type and length of the original data (such as a credit card number) but replaces it with a bogus equivalent called a token. This approach can be used to retain the format of the original data without incurring the risk of exposure.
What is data masking?
Data masking is the general replacement of a character of data with another character of data. An example of masking would be converting 123-45-6789 into ***-**-6789.
What is cryptographic erasure?
The strength of encryption is based on the idea that encrypted data cannot be decrypted without the encryption key. This also means that if the key is intentionally destroyed, the encrypted data can never be decrypted and is effectively made useless. This process is called cryptographic erasure.
What is a hardware security module (HSM)?
An HSM is a computing device or cloud service that generates, secures and manages encryption keys, performs encryption/decryption and other cryptographic functions. It acts as a root of trust for organizations looking for the highest level of security for their encrypted data and encryption keys.
