Cyera, Tuesday, October 27th, 2026
Cyera guide to data leak prevention in 2026 argues data classification must come before DLP rules, especially with AI agents.
Cyera's guide defines data leak prevention as the tools and policies that keep sensitive data where it belongs, and says cloud, remote work and AI have created new blind spots.
It argues most leaks happen because data was never classified as sensitive, not because a DLP rule failed.
The article covers data at rest, in motion and in use, noting legacy tools struggle with data in use by AI agents.
It describes content-based, context-based and AI semantic classification and reviews common leak causes including phishing, malware, insiders and misconfiguration.
