Data Loss Prevention (DLP) is a set of technologies and policies that detect and prevent sensitive data from being leaked, misused, or accessed by unauthorised users.
What DLP monitors
- Uploads to SaaS apps (OneDrive, SharePoint, Google Drive, Slack)
- Web uploads/downloads (personal email, social media)
- Cloud storage (AWS S3, Azure Blob, GCP)
- Endpoint traffic leaving user devices
How DLP inspects data
- Deep content inspection — scans documents, images, structured and unstructured data
- Context awareness — considers user, device, app, activity, and location
- Pre-built profiles — credit card numbers, health data, government classification markers
- Custom profiles — organisation-specific sensitive data patterns
