The Importance of Erasure Verification

The Importance of Erasure Verification 

Companies are closely examining their data security practices due to data breaches and misplaced storage media stories publicised in the last few years.

Erasure verification is a crucial step in any data security practice. When creating a process for media repurposing or disposal, it is the only way to ensure your process is completely effective at sanitising media.


Why is sanitisation necessary? 

Theft of sensitive data: Leaving sensitive information on any data storage device that is damaged or reaches the end of its life cycle puts your organisation at risk for theft, accidental exposure or legal ramifications.

Poor control of internal data accessibility: Using an erasure verification process on an employee’s computer after they leave a company – and before that computer is given to another employee – helps limit access to sensitive information.

Regulatory compliance violations: Data privacy and retention regulations force organisations to both retain and dispose of certain data and prove that proper procedures are in place to maintain compliance. Data erasure software or erasure hardware will help your organisation better meet these regulations.

Data security is vital

Our Process 

  1. Device Preparation Media (HDD, SSD, etc) is prepared by writing known specified data patterns to the device prior to running sanitisation procedures. The device can be prepared by Kroll Ontrack or the customer.
  2. Sanitisation Procedure The media/device is then sanitised using the customer’s sanitisation process. The process can be run by Kroll Ontrack or the customer.
  3. In-depth Analysis Performed The media/device is then thoroughly searched and analysed looking for any remnants of data that may exist in any portion of the device including user data, bad/defective blocks, spare pool areas, etc.
  4. Detailed Report Created A final report is delivered to the customer detailing the process that was used to prepare, sanitise, and analyse the device and the results of the analysis.
