The problem
A DLP policy is the beginning of the investigation, not the end.
Organizations implement DLP policies to prevent sensitive information from leaving their environments. When a policy match or alert occurs, security and data-protection teams still need a clear, evidence-supported way to investigate what happened and determine the appropriate next step.
What happened and who was involved?
What sensitive information was at risk?
Was the activity blocked, allowed, audited, or overridden?
Was the behavior isolated or part of a larger pattern?
What additional investigation is required?
How should the organization respond through its approved workflow?
The NLCS solution
From data protection to threat detection.
NLCS helps define the supported integration path, validate selected controls and telemetry, and document the workflow that connects data-protection signals to security investigation. Available capabilities depend on connectors, event types, auditing, licensing, permissions, and cloud environment.

Discover
Clarify information flows, sensitive-data use cases, DLP scope, security telemetry, and operational requirements.
Protect
Assess and improve the selected Purview information-protection and DLP controls.
Integrate
Identify supported connector, diagnostic, audit, or Defender XDR integration paths for the environment.
Detect
Develop agreed correlation use cases, KQL queries, analytics rules, and investigation context.
Investigate
Design incident investigation workflows, evidence collection, and ownership handoffs.
Optimize
Validate selected use cases, document findings, and refine control and detection quality.
A scoped engineering engagement
Deliverables that make the operational path visible.
Deliverables are selected after discovery and confirmed in the engagement scope. NLCS does not provide an outsourced SOC, 24/7 monitoring, managed detection and response, or automatic incident remediation.

Selected DLP incident and activity paths
The Defender XDR connector can import supported DLP incidents into Sentinel; related Office 365 activity needs the relevant CloudAppEvents path. The separate Purview Sentinel solution uses data-sensitivity diagnostic logs, not a blanket DLP-alert feed. Tuning, ingestion, license, and retention settings matter.
Read official documentation for Selected DLP incident and activity paths (opens in a new tab)Documentation reviewed November 5, 2026. Microsoft availability and preview status can change; scope approval includes a fresh tenant-specific check. These are documented capabilities and constraints, not claims of completed NLCS customer deployments.
