The idea of this thesis was to create a secure way to retire devices from Oura Health Oy. The company did not have any dedicated solution for the device retirement. The implementation utilized a company specialized in device wiping called Blancco Technology Group, which provided software for compliant data destruction. Data sanitization ensures that sensitive data cannot leak out of the company. The outcome was positive. A reasonable solution was devised for the secure and environmentally friendly disposal of devices. Company will have a compliant solution for the future.
