DSPM and DLP are often discussed as rivals. In practice they are layers of the same strategy, and the strongest programmes use them together.
What DLP does
DLP is enforcement: it monitors and blocks sensitive data as it tries to leave through email, web, cloud, USB and print. It is the action at the edge.
What DSPM adds
DSPM is the broader posture: continuously finding sensitive data, classifying it, scoring its risk, and monitoring its integrity — the context that makes enforcement precise.
Better together
Discovery and classification feed DLP so it enforces on real labels; monitoring proves nothing was tampered with. In Siberson, they share one console, so the loop runs without integration friction.
