Secure deletion depends on the storage medium
Peter Gutmann’s 1996 article discusses data remanence and the limits of overwriting magnetic and solid-state storage, underscoring why sanitization methods should account for the medium.

What happened and what to do
Peter Gutmann’s 1996 article examines data remanence and secure deletion in magnetic and solid-state memory. Its topics include the limits of overwriting data once on magnetic media and the importance of considering the storage medium when choosing sanitization methods.
A company can turn these principles into verifiable procedures: inventory media and data, define erasure methods by device type, record each operation, and monitor exceptions. Where overwriting is not appropriate, the process should provide a suitable alternative sanitization method and retain evidence for audit.
How the consultancy can help
Wendelmaques can diagnose risks in media disposal and reuse, propose procedures for each storage type, and implement records, controls, and sanitization monitoring.
