Data deletion

📑 No exception and no wiggle room!

Your laptops are in safe hands with us. Regardless of whether they have already been cleaned or not, all disks undergo the same processes to achieve maximum security.

Standards and certifications

In general, all our processes are based on the following guidelines:

• Data deletion: NIST 800-88 (Clear / Purge)
• Data carrier destruction: DIN 66399 / ISO 21964

🍂 Data erasure before destruction

Destruction of disks is no better than a clean deletion. That is why we endeavour to reuse disks in the best possible way.

⚠️ Be careful with «certified» deletions!

Standards such as ISO 9001, ISO 14001 and ISO 27001 say nothing about how securely data is deleted and how disks are being handled.

This is a popular «trick» used by IT service providers to feign security that has never been externally tested and verified. In any case, our organisation is effectively certified.

How does data erasure work?

Depending on the data carrier and its capabilities, our erasure system selects one of the secure Secure Erase / Sanitise commands. Verification takes place after successful execution of these erasure methods.

🔎 Verification is essential!

A command can be executed quickly. The only way to prove whether or not it has been properly cancelled is with verification. To do this, our deletion system compares the statuses before and after the deletion: and it is precisely this comparison that is not easy!

🤷 Where can I see the details of the cancellation?

The classification of erasure processes is carried out according to the «Clear» and «Purge» categories defined in NIST 800-88 in the Audit trail per disk.

How does the destruction work?

If a disk cannot be deleted or accessed, it is physically destroyed. For this purpose, our organisation has industrial shredder systems as well as a camera system that is unique in Switzerland and creates a video as evidence for each destruction process.

🔎 Trust is good, proof is better!

If a disk is installed in a storage device, the risk of data loss is still relatively low. But what do the processes look like as soon as a disk is removed? We can track the path of every disk down to the metre and second.

🤷 Where can you see the details of the destruction that took place?

Destruction processes are classified according to the safety levels defined in DIN 66399 / ISO 21964 in the Audit trail per disk. In addition, all videos are also stored individually in the audit trail.

Storage until deletion / destruction?

Triple secured

The processing site is generally burglar-proof, has a video surveillance system and an alarm system that alerts us and the police in the event of a break-in.

🚨 Additional protection for unprocessed goods

Unslaked goods are stored in an additionally secured and hardened area of our processing area. This area is again separately monitored and alarm-protected.

Audit trail

🧑🏼‍🔧 Free of charge, ready to use and audit-proof

It should be easy for donors to understand what has been deleted and how. That's why we have a very detailed deletion documentation that shows all the work carried out.
