Secure data erasure is the removal of information from drives, phones or servers so it cannot be recovered, even with forensic tools, for example by overwriting the media, using cryptographic erase or physically destroying it, following standards such as NIST SP 800-88. It is essential before selling, recycling or returning equipment, because deleting files or formatting is not enough.
