What is AWS IoT Device Defender?
AWS IoT Device Defender protects IoT device fleets through continuous security checks and behavior monitoring. The service identifies configuration weaknesses, detects anomalous device behavior, and enables rapid response to security incidents.
The audit component automatically checks whether IoT policies, certificates, and device configurations comply with security guidelines. Detect analyzes the runtime behavior of each device and reports deviations from the normal behavior profile.
For organizations with large IoT fleets, Device Defender is a central component of the security architecture: it automates security audits that would be impossible to perform manually across thousands of devices.
Core Features
- Audit: Automatic checking of IoT configurations against best practices
- Detect (Rules): Rule-based detection of behavioral deviations
- Detect (ML): ML-based anomaly detection for complex patterns
- Mitigation Actions: Automated responses to detected security issues
- Alert Integration: Notifications via SNS, CloudWatch, and Security Hub
Common Use Cases
Compliance Checking: Regular audits ensure all devices comply with security policies. Deviations are automatically detected and reported before they become risks.
Anomaly Detection: Devices sending unusual data volumes, connecting at unexpected times, or communicating with unknown endpoints are identified and isolated.
Certificate Management: Device Defender warns about expiring or revoked device certificates and identifies devices sharing certificates.
Benefits
- Automated security audits for large device fleets
- ML-based anomaly detection without manual rule configuration
- Integration with AWS Security Hub for centralized security overview
- Automated mitigation actions on security violations

Typical Use Cases
Frequently Asked Questions
What is AWS IoT Device Defender?
AWS IoT Device Defender is a security service for IoT device fleets. It checks device configurations against best practices, monitors device behavior for anomalies, and alerts on security violations. The service covers both cloud-side and device-side security.
How does Device Defender detect security issues?
Device Defender uses two mechanisms: Audit checks IoT configurations against AWS security best practices (e.g., overly permissive policies, expired certificates). Detect monitors runtime device behavior and identifies anomalies such as unusual connection patterns or data volumes.
What does AWS IoT Device Defender cost?
Audit costs are based on the number of devices checked. Detect charges per monitored metrics and data points. Typical costs for a fleet of 1,000 devices are 50 to 150 USD/month, depending on the number of monitored metrics.
