Acra is a database security suite designed for protecting sensitive and personal data. It offers application-level encryption, allowing for field-level encryption and multi-layered access control, along with intrusion detection capabilities. Acra is suited for distributed applications (web, server-side, and mobile) storing data in various databases and datastores. It employs a unique cryptographic design using AcraBlocks and AcraStructs to ensure data is protected even if application or database secrets are compromised. The core technology involves encrypting data as early as possible and operating on encrypted data, providing a defense-in-depth approach.
Acra offers selective encryption, enabling users to choose which data fields to encrypt based on security needs and performance considerations. It supports searchable encryption, allowing queries on encrypted data without decryption. Acra provides masking and tokenization features to further protect sensitive information. Architecturally, Acra offers AcraServer to proxy database traffic and AcraTranslator as an API-driven solution.
