This integration creates a closed-loop system where alerts trigger automated investigations, which in turn generate actionable intelligence that security teams can use to make informed decisions quickly.

Security Triage Agents in Action

The Tanium Security Triage Agents operate as specialized components within the broader security ecosystem, focusing on three key areas of investigation:

Endpoint Telemetry Analysis

When an alert triggers, the Endpoint Telemetry Agent immediately gathers comprehensive data from the affected system:

  • Process information: Detailed data about running processes, including parent-child relationships and execution context
  • Network connections: Active network connections and recent communication patterns
  • File system activity: Recent file creations, modifications, and access patterns
  • Registry changes: System and application configuration modifications
  • User activity: Login sessions, privilege usage, and behavioral patterns

This telemetry provides the foundational context needed to understand whether an alert represents genuine malicious activity or benign system behavior.

Identity Insights Correlation

The Identity Insights Agent focuses on understanding the human element behind security events:

  • User behavior analysis: Patterns of normal activity versus anomalous behavior
  • Privilege usage: Monitoring of administrative actions and privilege escalation attempts
  • Access patterns: Analysis of login locations, times, and resource access
  • Credential validation: Verification of authentication events and session management

By correlating identity information with endpoint activity, the agent helps security teams understand whether alerts represent compromised accounts, insider threats, or legitimate user actions.

Automated Investigation Workflows

The triage agents follow predefined investigation playbooks that mimic the steps a human analyst would take:

  1. Initial assessment: Determine alert severity and potential impact
  2. Context gathering: Collect relevant data from endpoints and identity systems
  3. Correlation analysis: Look for related events across the environment
  4. Threat intelligence matching: Compare findings against known threat indicators
  5. Risk scoring: Assign a confidence level to the alert based on collected evidence

This automated workflow reduces the time from alert detection to investigation completion from hours to minutes, dramatically improving response capabilities.

Real-World Benefits for Security Teams

Organizations implementing Tanium Security Triage Agents with Microsoft Security Copilot report significant improvements in their security operations:
