Single drive encryption keys protect sensitive data at rest or in transit by blocking unauthorized access. They provide security and reliability without affecting drive performance. When used with Ciphertex® single drives, they support comprehensive archiving, backup, and storage—making them an ideal solution for secure business use. Additional encryption keys can be purchased by sending Ciphertex® an existing key to duplicate. If all keys are lost and none are available to copy, a new key cannot be created.
