DataLocker EncryptDisc is a software solution for encrypting data stored on optical media, including DVD, CD, and Blu-ray discs. It uses FIPS 140-2 validated AES 256-bit encryption and includes a built-in disc-burning application that is embedded directly on the disc, eliminating the need for any third-party software installation on the host system. The solution supports a range of optical media formats: Blu-ray discs (up to 100GB), DVDs (up to 8.54GB), and CDs (up to 700MB). It also supports M-DISC media, which is marketed as offering archival-grade storage durability for up to 1,000 years. EncryptDisc operates without requiring administrative privileges, making it accessible to standard domain and local user accounts. It is compatible with Windows operating systems from Windows XP through Windows 11 and works with any standard disc-writing hardware. Users interact with an embedded Unlocker application stored on the disc itself. The workflow involves inserting the disc, setting a password, dragging and dropping files, and finalizing the disc. Discs can be finalized as read-only or left writable for future additions. The product is designed to meet compliance requirements including HIPAA, GDPR, and CMMC, and is positioned for use cases such as secure data transfer between systems, long-term archiving, and distribution of sensitive information in regulated industries such as healthcare, government, legal, and financial services.
