What is Data Encryption?

Encryption transforms readable data into an unreadable format using cryptographic algorithms, protecting confidentiality by ensuring only authorized parties with the correct key can access the data.

Encryption uses mathematical algorithms to convert plaintext data into ciphertext that is unreadable without the corresponding decryption key. Encryption at rest protects stored data, while encryption in transit protects data moving between systems. End-to-end encryption ensures data is encrypted from origin to destination.

Encryption is a fundamental technical measure for GDPR Article 32 security requirements and is referenced across most privacy regulations. Under GDPR, properly encrypted data that is breached may not require individual notification if the encryption rendered the data unintelligible. ProtectIQ provides encryption capabilities integrated with data discovery and classification.
