Hardware data encryption devices provide the highest level of protection for information stored on physical media, including magnetic tapes used for data backups. Dedicated encryption solutions protect data at rest from unauthorised access – even in the event of theft or loss of the media. In an era of increasing cyberattacks and regulatory requirements, data protection has become a key element of every organisation's security strategy.
This guide is dedicated to IT administrators, security managers, and individuals responsible for data protection in companies of all sizes, presenting the principles of hardware encryption and the benefits of its implementation.
A data encryption device is dedicated hardware that performs cryptographic operations using its own circuits, isolating encryption keys from the operating system. In a corporate environment, such solutions are used to secure backups, archive data, and store information long-term on LTO (Linear Tape-Open) tapes.
The basic principles of hardware encryption are based on the AES-256 (Advanced Encryption Standard) algorithm in XTS mode, which transforms data into an unreadable form without the proper key. Cryptographic keys are generated and stored in a secure module – they never leave the device, providing an additional layer of protection against attacks.
Senetic offers a professional HPE solution for encrypting backup data – HPE StoreEver 1/8 G2 Tape Autoloader & MSL Tape Library Encryption Kit.
The tape autoloader/tape library is a solution for automatically archiving data on LTO magnetic tapes. It is a system:
The device is in a 1U rack form – it occupies one unit height in a server cabinet.
Encryption Kit adds data protection features:
Recommendations for various use scenarios: the solution is ideal for financial institutions requiring long-term data archiving, the healthcare sector with sensitive patient data, and companies performing regular backups to tapes in data centres.

The device uses dedicated cryptographic circuits to transform data into an encrypted form. Keys are generated and stored inside a secure module, allowing for the protection of information even in the case of physical access to the media.
Hardware encryption provides isolation of keys from the operating system, higher performance (does not burden the CPU), and better resistance to malware attacks. Software solutions are cheaper but dependent on system resources and potentially more vulnerable to security flaws.
Small businesses can use SSDs with built-in AES-256 encryption. Corporations with large volumes of backup data should consider dedicated encryption kits for tape libraries, such as the HPE AM495A.
Hardware encryption minimises the impact on performance due to dedicated cryptographic processors. Operations are carried out independently of the server's CPU, which is important during large transfers when creating backups.
Devices with FIPS 140-2/3 certifications should be implemented, secure key management (backup, rotation) should be ensured, and procedures should be documented for regulatory audit requirements.
