Once answered select what is the right hard drive destruction option below:

1. Hard drive wiping

Data wiping involves overwriting data from an electronic medium using specialist software to ensure the data is permanently destroyed. Using Blancco software to wipe hard drives is the only way to guarantee this process 100% as it destroys the data to international standards, that have been tested, certified and approved by over 15 governing bodies including National Cyber Security Centre, ADISA, BSI.

2. Degaussing

Destroying data with a high-powered magnet to disrupt the magnetic field of the device. However, because the hard drive is inoperable once carried out, you cannot prove if the information inside the hard drive has been destroyed, it also is not very environmentally friendly either.

3. Physical destruction

Which does fully destroy the hard drive and therefore the data however, if carried out by a destruction company they cannot fully prove the hard drive destruction as simply receiving a certificate of destruction does not prove it absolutely.

Secure end-of-life management processes such as destroying hard drives securely is now a critical IT concern as using a professional destruction process is a legal requirement for any business. Asset management to track inventory of hard drives sent for destruction, needs a full proof system that details when and how the data was destroyed and disposed of. Making sound decisions when choosing a destruction partner to carry out hard drive destruction is key to protecting your companies reputation and risk.

How you mitigate the risks:

1. Using On-Site Security

Keeping data secure using passwords and access level whilst the equipment is being used is a well-known process, but also consider where you are storing broken IT equipment as this also creates risk.

2. Secure Chain of Custody

A professional destruction company provides a chain of custody tracking all the way until they are destroyed and disposed of.

3. Hard Drive Wiping

By working with a company that uses Blancco software you have mitigated all risks at this stage.

4. Certifications

You must ensure that the hard drive destruction service comes with a certification of destruction, as well as an inventory report linking the wiping licence number with the equipment serial number proving the wiping through Blancco (a third party).
