Secure Data Deletion Service 26/2/2014

Every company needs to regularly replace their computer systems and often wish to do so in an environmentally friendly way. Many companies will want to pass on their old computers to a charity. The question is how do you ensure that the data has been securely deleted from the hard drives prior to disposal? In many cases the hard drives have just been reformatted. While this appears to have removed all the data, it still resides on the hard drive and can be easily recovered by software programs, months or years later.

The only way to ensure the data has been truly deleted from the hard drive so it cannot be recovered is to carry out a secure data deletion process.  This is often referred to as a forensic wipe of the hard drive. Orion’s secure data deletion service provides an environmentally friendly way for companies in Thailand to dispose of their old hard drives. Once secure data deletion has taken place the hard drives can still be reused.

At Orion we use Blancco which is the proven data erasure solution for millions of users around the world. A tamper proof data erasure report is provided proving that the data deletion was successful.

The whole process is auditable ensuring compliance with IT security standards such as ISO27001, ISO15408, PCI and FISMA.
We are able to carry out the secure data deletion to the following magnetic erasure standards


  • HMG Infosec Standard 5, Lower Standard
  • Air Force System Security 5020
  • HMG Infosec Standard 5, Higher Standard
  • US Army AR380-19
  • Peter Gutmann’s Algortihm
  • German Standard VSITR

Maybe you already have a scheme in place to securely remove the data from your hard drives and would like to confirm it is being done properly. Orion would be happy to verify that there is no data on one test drive you provide, free of charge.
