Businesses that handle and process personal data must be equipped with safeguards to protect and use the highest possible privacy settings by default so that the information is gathered legally and within the specified constraints, and also to ensure that it is safeguarded against misuse and exploitation. If a business is not compliant, they may face penalties.
