Introduction
Rapid7 InsightIDR is a cloud-native SIEM + XDR platform designed to help SOC teams detect, investigate, and respond to threats faster. Unlike legacy SIEMs that overwhelm analysts with logs, InsightIDR uses AI-driven analytics and correlation across endpoints, users, and network data to prioritize meaningful alerts.
It is widely adopted by enterprises for threat detection, incident response, and compliance reporting.
Core Capabilities
1. Data Collection & Correlation
- Ingests data from endpoints, servers, firewalls, cloud apps, and SaaS platforms.
- AI correlation engine stitches together alerts into Incidents instead of isolated events.
- Provides a centralized SOC dashboard with risk scoring.
2. User & Entity Behavior Analytics (UEBA)
- Establishes baselines for normal user activity.
- Detects anomalies like impossible travel logins, privilege escalations, insider threats.
- Flags credential abuse and lateral movement attempts.
3. Endpoint Detection & Response (EDR) Integration
- Monitors endpoint activity such as process creation, PowerShell execution, and file access.
- Detects malware, ransomware precursors, and fileless attacks.
- Integrates with Rapid7 Insight Agent for live response.
4. Automated Response (SOAR Capabilities)
- Provides prebuilt playbooks for isolating compromised devices, disabling accounts, and blocking IPs.
- Integrates with InsightConnect for advanced SOAR automation.
- Reduces MTTR (Mean Time to Respond) through automation.
5. Threat Intelligence
- Enriched with Rapid7 Threat Command feeds.
- Maps detections to MITRE ATT&CK tactics and techniques.
- Prioritizes exploited vulnerabilities and active campaigns.
Technical Architecture
- Insight Agents → Deployed on endpoints for telemetry and response.
- Collectors → Aggregate logs from firewalls, AD, SaaS, and cloud platforms.
- InsightIDR Cloud → AI correlation + analytics engine.
- Security Console → SOC dashboard for incidents, investigations, and reports.
