How Microsoft Purview Insider Risk Management Helps You Stay Ahead of Internal Threats

Atle Skjekkeland

Loading

In today’s hybrid work environment, where sensitive data flows across devices, apps, and geographies, insider risks have become one of the most complex and costly threats to manage. According to Microsoft research, insider incidents account for 20% of data breaches and cost organizations an average of $7.5 million per incident. Worse, they take an average of 85 days to contain. 

Microsoft Purview Insider Risk Management (IRM) is designed to help organizations detect, investigate, and mitigate these risks—intelligently, privately, and at scale.

Why Insider Risk Management Matters More Than Ever

Insider risks aren’t just about malicious intent. They include accidental data leaks, policy violations, and risky behaviors that can lead to compliance failures or reputational damage. With the rise of GenAI tools, the attack surface has expanded to include sensitive data in AI prompts, unauthorized app usage, and shadow IT.

IRM addresses these challenges with a privacy-first, machine-learning-driven approach that integrates seamlessly with Microsoft 365, Microsoft Defender, and Microsoft Entra.

1. AI-Powered Risk Detection

IRM uses over 100 built-in indicators to detect patterns of risky behavior—such as renaming sensitive files before saving them to USB, or gradually exfiltrating data over time. These indicators support:
– Sequence Detection
– Cumulative Exfiltration Detection
– High-Impact User Identification

2. Adaptive Protection 

This feature dynamically applies to the most effective Data Loss Prevention (DLP) and Conditional Access (CA), based on a user’s risk level. It transforms static policies into responsive, context-aware controls. 

3. Privacy by Design 

IRM is built with strong privacy controls to maintain employee trust 

  • Pseudonymization by default

  • Explicit policy opt-in 
  • Full audit logs 

Getting Started: Quick Wins and Best Practices 

  • Run Analytics First 
  • Use Policy Templates 
  • Define Stakeholders Early 
  • Start with High-Impact Use Cases

Final Thoughts 

Microsoft Purview Insider Risk Management is more than a compliance tool—it’s a strategic capability for protecting your organization’s most valuable assets.
