When building out Sensitivity Labels for organisations, I will always advise my customers to also build out Data Loss Prevention Policies to prevent some labels from being shared externally. This example will utilize Labels that are created for ‘Internal’ use only. As a result, when items have been classed with this label, it is declaring this data to, of course, stay within the organisation.
Therefore, I have created a quick video on how to prevent items that have been labelled with a Sensitivity Label from leaving your organisation.
