TL;DR: Data security programs break when they rely on shallow telemetry and brittle rules instead of endpoint presence, data lineage, and contextual AI, according to Cyberhaven’s analysis. In the agentic AI era, that gap widens because AI agents and users move data across endpoints and applications faster than cloud-only controls can see.
Editorial analysis by NHI Mgmt Group, based on content published by Cyberhaven: “The Three Pillars of Durable Data Security: Presence, Lineage, and AI”.
By the numbers:
- 49.5% of developers were using desktop-based AI coding assistants by December 2025, up from roughly 20% at the start of that year.
Key questions
Q: What breaks when data security tools only see cloud activity and not endpoint behaviour?
A: They miss the actions that create the risk, such as local copy, paste, storage, and redistribution before the content reaches a cloud service.
Q: Why does lineage matter more when AI agents handle sensitive data?
A: AI agents can move context and content across tools without a human approving each step, so a simple destination check is no longer enough.
Q: How do security teams know whether contextual AI is actually improving data controls?
A: They should look for fewer false positives, better policy recommendations, and decisions that reflect observed behaviour instead of assumed workflows.
Practitioner guidance
- Strengthen endpoint telemetry coverage Instrument the endpoint layer where files are opened, copied, pasted, stored locally, and redistributed so security teams can see the actions that create data risk.
- Build lineage-aware policy logic Use observed data movement patterns to distinguish routine collaboration from risky transfer chains, especially where the same content moves across SaaS, local tools, and AI systems.
- Gate AI and agent workflows on telemetry quality Do not rely on contextual AI for data security decisions until the underlying behavioural data is longitudinal, complete, and rooted in real organisational workflows.
Bottom line: Data security weakens when controls can see outcomes but not the endpoint actions and movement chains that created them.

Presence, lineage, and AI are now the minimum viable architecture for durable data security. Static rules and cloud-only visibility fail because they see outcomes, not the path data took to get there. As AI agents and users move content across endpoints, SaaS tools, and local context windows, the control problem shifts from blocking a destination to understanding the full movement chain. Practitioners should treat endpoint visibility as a governance prerequisite, not a monitoring enhancement.
A few things that frame the scale:
- 28% of secrets incidents now originate outside code repositories, in Slack, Jira, and Confluence, and are 13% more likely to be categorised as critical than code-based leaks, according to the State of Secrets Sprawl 2026.
A question worth separating out:
Q: What is the difference between data lineage and standard event logging for security?
A: Event logging records isolated actions, while lineage connects those actions into a sequence that shows how information was created, transformed, and moved. For security, that difference matters because risk often appears in the chain, not in a single event. Lineage is what makes the sequence understandable and enforceable.
