Data Loss Prevention (DLP)

Data Loss Prevention (DLP)

This aims to prevent the unauthorised loss or exfiltration of data. DLP solutions typically monitor data traffic that leaves a network for document tags, watermarks and “DLP fingerprints”. DLP functionality often comes bundled with many UTM firewalls. While DLP solutions as touted by DLP vendors might be marketed as watertight, a lot of these “solutions” can be circumvented by IT-savvy insiders.
