Radius Transparent Data Encryption (TDE) exists so that never happens again. It encrypts your data and logs at rest, securing them with a master key managed by the database or an external service. When TDE is active, even if someone gets physical access to your database files, they get nothing but encrypted blobs. This is not an optional safeguard. It is the line between storing valuable information and leaving it exposed.
TDE in Radius is engineered for performance and simplicity. Encryption is handled at the storage level, meaning your applications do not need to change. The encryption and decryption process is transparent to queries, transactions, and workloads. Everything keeps running as before, except your data is now unreadable to anyone without the proper keys. This is critical for meeting compliance requirements like GDPR, HIPAA, or PCI DSS, and for protecting intellectual property.
To enable Radius Transparent Data Encryption, you set up a database encryption key, protect it with a certificate, and store it in a secure vault. You can rotate keys without taking the system offline. You can audit every cryptographic operation. You can integrate with hardware security modules (HSMs) or cloud key management systems (KMS) for even greater control. The architecture is designed so that stolen files hold no usable content. Removing access to the keys renders any copied database inert.
