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.

Encryption at Rest
Encryption at rest protects stored data by encrypting it on disk, in databases, or in storage systems, ensuring data confidentiality even if storage media is physically compromised.
Encryption in Transit
Encryption in transit protects data as it moves between systems using protocols like TLS/SSL, preventing interception and eavesdropping during transmission.
Data Tokenization
Tokenization replaces sensitive data with non-sensitive tokens that can be mapped back to the original data through a secure token vault, protecting data while preserving processability.
Data Masking
Data masking replaces sensitive data with realistic but fictitious values, protecting privacy while maintaining data utility for testing, development, and analytics.
