Understand data protection and governance tasks for Microsoft 365 and Copilot

Insider Risk and Communication Compliance

Differentiate risky user-behavior investigation from review of policy-relevant communications.

What you need to know

  • Insider Risk Management correlates configured indicators and triggering events to surface potentially risky user activity.
  • Communication Compliance detects and supports review of messages that might violate regulatory, business-conduct, or organizational communication policies.
  • Both solutions use privacy-aware workflows, scoped roles, alerts, and human review.

Objects and administrative surfaces

  • Policies, alerts, users, cases, and indicators — Microsoft Purview portal.
  • Communication reviewers and Insider Risk investigators require distinct role assignments.

How it works

  • Policy matches and risk indicators are signals for review rather than automatic conclusions about intent.
  • Solutions can integrate signals, but each retains its own investigative purpose and permissions.

When to use it

  • Use Insider Risk Management for patterns such as unusual exfiltration by a departing employee.
  • Use Communication Compliance for harassing, threatening, regulated, or otherwise policy-relevant messages.

Security and governance implications

  • Apply need-to-know roles, pseudonymization where available, and documented escalation.
  • Avoid using either solution as unreviewed employee surveillance.

Troubleshooting signals

  • Confirm policy scope, indicators/classifiers, trigger conditions, reviewer roles, and processing time.
  • Open the alert evidence before escalating it to a case.

Exam traps

  • DLP focuses on sensitive-data handling; Communication Compliance focuses on messages; Insider Risk combines user-risk indicators.
  • An alert needs investigation and does not independently prove wrongdoing.

Key takeaways

  • Risky user pattern → Insider Risk; risky message → Communication Compliance.
  • Protect privacy and require human review.

Exam fidelity: Microsoft does not identify the specific item types that will appear on an individual exam before delivery. This lane counts multiple-choice and multiple-response items as exam-style practice. Ordering and matching are supplemental learning exercises and do not count toward exam-style accuracy. Difficulty labels are calibrated to AB-900 Fundamentals, not a Microsoft-published question rating.
