Legacy data loss protection (DLP) solutions address one third of the problem

Data can do a lot of things, but it can’t leave your organization by itself. A person is always behind a data loss incident, whether they are careless, compromised or malicious. Legacy solutions focused on content alone can’t identify and mitigate the risks that people pose to the data they can access.

Proofpoint Sigma is the integrated information protection platform that provides unmatched visibility into data risk by analysing content, behaviour and threats from a single cloud-native console, stopping data loss while saving time and operational cost.
