We have 13 years experience ensuring hard drive data is securely destroyed, we mainly use an industrial shedder and shred the drives, or we do sometimes use kill disk to wipe the hard drive. DoD 5220.22-M (U.S. Department of Defense standard): Overwrites data 3+ times.
We also have an electric degausser which Uses a strong magnetic field to disrupt the magnetic domains on the drive, effectively erasing all data (works on HDDs, not SSDs).
Either way your data is securely destroyed. You will receive a certification with every hard drive serial number, the date and the method used to destroy. You can also request a method of destruction.
To prevent data breaches during transit:
- Devices are stored in locked containers
- Transport is done with tracked and sealed vehicles
Staff handling data undergo background checks and training
We have Regular audits and random sampling ensure data wiping procedures are effective.
