Data is the new oil - right?
Our modern world runs on data. Companies generate, store and process huge amounts of it every day. But what happens to this data when a device has reached the end of its life cycle? All too often, data on old laptops, smartphones or servers is simply forgotten - and that can be expensive. Data loss or leaks lead to financial damage, loss of reputation and legal consequences. This is where certified data erasure comes into play: an inconspicuous but crucial process that protects companies and preserves value at the same time.
The most important in a nutshell
- Formatting or resetting does not delete data securely – it can often be recovered with simple tools.
- Certified data deletion removes all data and leaves the device functional – it can be sold.
- Any deletion should be documented with a certificate for each serial number; non-removable data carriers will be destroyed.
Certified data erasure: more than just "formatting"
A simple click on "Factory settings reset" is not enough to securely delete data. Modern recovery tools can restore information even from supposedly empty devices.
Certified data erasure means:
- Complete data destruction - with verifiable protocols.
- Compliance with data protection laws – as required by the GDPR – and with recognized standards such as those of the BSI.
- Sustainability through reuse - Data is removed, the device remains usable.
This method makes IT hardware safely reusable, which makes both ecological and economic sense.
Added value through used IT
After a certified data erasure, devices that are still functional can start a new life cycle:
- Resale: Companies can offer their old devices on the market and thus generate additional revenue.
- Donations: Used IT can benefit schools, social institutions or start-ups.
- Remarketing: Through specialized providers such as Second IT devices get a second life and companies benefit from professional service.
Sustainable use of IT resources is not only environmentally friendly, but also a competitive advantage.
The risks of insecure data deletion
A seemingly harmless device can become a security risk if it falls into the wrong hands. Real-life examples show how sensitive business or customer data has been found on old hard drives - a nightmare for any company.
The cost of insecure data deletion:
- High penalties: Data protection violations can result in fines of millions of euros – up to 20 million euros or 4 % % of the global annual turnover (Art. 83 GDPR).
- Loss of reputation: Customer trust is quickly lost if a data leak becomes known.
- Economic damage: Unauthorized access to trade secrets can have immense consequences.
Delete or destroy? The right method for each data carrier
Technology and the condition of the data carrier are crucial:
| Data carriers | Recommended procedure | Proof |
|---|---|---|
| Functional hard disk drive (HDD) | Complete overwriting with certified software, with testing | Certificate of destruction by serial number |
| SSD and NVMe | Certified software with manufacturer-issued wipe commands – overwriting alone is not enough | Certificate of destruction by serial number |
| Smartphones and tablets | Certified mobile wipe | Certificate of destruction per device |
| Defective or unerasable data carriers | Physical destruction according to DIN 66399 | Certificate of destruction |
A good destruction certificate lists the device, serial number, method, result, and date and is digitally signed. As a Blancco ITAD Gold Partner, Second IT deletes with the Blancco Drive Eraser and generates a digitally signed deletion certificate for each device.

Conclusion: safety and sustainability go hand in hand
Certified data erasure is not a luxury, but a necessity in today's IT world. It not only protects sensitive information, but also enables companies to get the most out of their hardware.
A safe end for your IT means a sustainable new beginning. Have your old devices professionally erased - for more security, added value and a smaller ecological footprint.

Frequently asked questions about certified data deletion
What is a certified data deletion?
With certified data deletion, all data is removed using verified software in a way that it cannot be recovered using laboratory methods. The result is verified and recorded in a protocol. A deletion certificate with a serial number is created for each device. This allows you to prove to data protection officers and auditors that the deletion has taken place.
Does formatting or resetting to factory settings suffice?
No. When formatting, only the contents of the data carrier are usually deleted; the actual data remain intact. Even resetting does not always reliably remove all areas. With freely available tools, such data can often be recovered. For corporate devices, therefore, a certified deletion with proof is necessary.
Can a deleted device be sold afterwards?
Yes, that is exactly the advantage over destruction. After a certified wipe, the data carrier remains fully functional. The device can be prepared for resale and your company receives revenue. Only defective or unerasable data carriers must be physically destroyed.
Data gone, value remains – with a certificate for every device.
