We do not anticipate any changes in Data Protection after Brexit
Block users from sharing personal data outside school e.g. NI numbers, NHS numbers, URT tax numbers , credit card details , bank numbers etc- Make sure to add your office admin team to bypass the rule.
Using data loss prevention (DLP), you can create and apply rules to control the content that users can share in Google Drive files outside the organisation. DLP gives you control over what users can share, and prevents unintended exposure of sensitive information such as credit card numbers or identity numbers.
