DLP can be enforced on the endpoint, on the network, or both. Choosing the right centre of gravity is one of the most consequential decisions in a data-protection programme.
Network DLP
Network DLP inspects traffic at the gateway or proxy. It is useful for centralised web and email egress, but it is blind to actions that never cross the monitored boundary — a USB copy, a local print, or an encrypted channel it cannot decrypt. Remote and hybrid work has widened these gaps considerably.
Endpoint DLP
Endpoint DLP enforces where the data lives and moves: email clients, browsers, USB, print, clipboard and cloud-sync folders. Because it runs on the device, it keeps working offline and off-network, and it can act on the file's classification before anything leaves. This is why Siberson Verikor is endpoint-first.
The pragmatic answer
Start on the endpoint for the broadest coverage and the least blind spots, then layer network controls where you need centralised inspection. One policy engine and one console across both keeps operations manageable.
