DLP
(Data Loss Prevention)
Controls that detect or prevent sensitive data from leaving approved places
What's it for?
Helps stop sensitive information being sent, copied or uploaded somewhere it should not go.
For example…
DLP blocks an email that tries to send a spreadsheet of national insurance numbers to a personal address.
DLP detects a spreadsheet containing customer card numbers being attached to a personal email and blocks the message before it leaves.
Think of it like…
Checkpoint for outgoing parcels that flags valuables leaving without authorisation
