Validate Successful Data Erasure

ClaraCheck validates effective data erasure across all addressable locations on an HDD or SSD. This validation step can be used on a subset of drives, or all drives, as a measure to confirm data sanitization. 

White not obvious at first, verifying the selected information and Disposal process is an essential step in maintaining confidentiality. Two types of verification should be considered. The first is the verification every time sanitization is applied. The second is a representative sampling verification, applied to a selected subset of the media. If possible, the sampling should be executed by personnel who were not part of the original sanitization action. If sampling is done after full verification in cases of low risk tolerance then a separate validation tool than the one used in the original verification should be used.”   NIST – 4.7 Verification Methods

Clarabyte’s data sanitization software products offer built-in verification of erasure for each erasure event. ClaraCheck offers the complete solution with secondary validation of successful erasure.  

Key Details About ClaraCheck

• Verifies that all addressable locations on a drive were effectively sanitized 

• Prove compliance with the most rigorous data protection regulations or guidelines through tamper-proof reporting

• Developed by an independent ClaraCheck team so that validation is different than the verification performed by ClaraWipe
