How Can Businesses Safely Delete Customer Data?

• Identify all storage locations: Before deleting information, identify where it is stored, including databases, CRM systems, shared drives, email accounts, archived files and third-party platforms.
• Use secure deletion methods: Select deletion methods appropriate to the storage system and sensitivity of the information. Businesses should ensure that deleted data cannot be easily recovered through ordinary access.

• Obtain vendor confirmation: Where customer data is stored by third-party service providers, businesses should request confirmation of deletion where appropriate and ensure that contractual deletion obligations are followed.
