Data Sanitization


At TES, we care for your data following your individual requirements. Our process is a complete approach to IT asset disposition – it not only ensures that all data is effectively removed from retired media, it governs the entire chain of custody as well. Our service starts with an intensive consulting phase where we define together with our customer how the data on the returned media is to be regarded and processed. From logistics services and the tracking of assets within our processing center to the final disposition of each asset and the serialized audit trail, our process allows us to offer unsurpassed service, legislative compliance, protection, and residual value capture.


We offer options to erase data either at our facility when equipment is received or onsite at our customer’s premises:


  • The data sanitization is performed to meet your requirements up to compliance with the new NIST 800-88.R1 standard (supersedes Department of Defense 5220-22-M standard) which is widely recognized by governments, OEMs, and global 2000 companies as the standard of measure; 5-pass and 7-pass overwrite options are also available.


  • The sanitization process based on NIST ensures that no data can be restored by extended keyboard attacks (NIST CLEAR) or extended laboratory attacks (NIST PURGE), depending on your independent requirements. Drives with damaged sectors that cannot be overwritten or with failed erasures are removed and destroyed.


  • Proof of successful completion of the data erasure is provided through a certificate of data sanitization.


  • Process audits and third party audits are performed to ensure complete compliance.


Whatever your company’s information security needs, TES can provide a solution or suite of solutions to meet them.
