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 provides contextual information to enable rapid response to security incidents.
The audit component automatically checks whether IoT resources, policies, certificates, and device configurations comply with AWS security best practices. Rules Detect and ML Detect continuously analyze security metrics from devices and AWS IoT Core and report deviations from expected behavior.
For organizations with large IoT fleets, Device Defender is a central component of the security architecture: it automates security audits that would be impractical to perform manually across thousands of devices.
Core Features
- Audit: Automatic, schedulable checks of IoT resources and configurations against best practices
- Rules Detect: Rule-based detection of behavioral deviations using self-defined metrics
- ML Detect: Automatically trained ML models (cloud-side and device-side metrics) for anomaly detection without manual rules
- Mitigation Actions: Built-in actions such as certificate rotation, policy rollback, or assignment to a thing group
- Alert Integration: Publishing of results to the AWS IoT Console, Amazon CloudWatch, and Amazon SNS
Typical Use Cases
Compliance Checking: Regular scheduled or on-demand audits ensure all device resources 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 via Rules Detect or ML Detect.
Certificate Management: Device Defender flags security-relevant configuration issues such as expired certificates or overly permissive policies and helps remediate them via Mitigation Actions.
Benefits
- Automated security audits for large device fleets without manual effort
- ML-based anomaly detection without manual rule configuration
- Close integration with AWS IoT Core, AWS IoT Greengrass, and AWS IoT Device Management
- Built-in mitigation actions for Audit and Detect alarms

Frequently Asked Questions
What is AWS IoT Device Defender?
AWS IoT Device Defender is a fully managed security and monitoring service for IoT device fleets. It checks device configurations against AWS security best practices, monitors device behavior for anomalies, and alerts on security violations. The service covers both cloud-side and device-side security metrics.
How does Device Defender detect security issues?
Device Defender combines three mechanisms: Audit checks IoT resources and configurations against best practices (e.g., overly permissive policies, expired certificates). Rules Detect monitors runtime behavior against user-defined rules. ML Detect automatically builds machine learning models from historical device data to identify anomalies without manual rule configuration.
What does AWS IoT Device Defender cost?
Audit and Detect are billed separately, both on a pay-as-you-go basis with no minimum fee. Audit is charged per active device principal per month, while Rules Detect and ML Detect are charged per metric datapoint, with ML Detect using tiered, higher per-datapoint pricing. Exact rates are available on the official AWS pricing page.
How does Device Defender integrate with other AWS services?
Device Defender works closely with AWS IoT Core, using its context for more accurate audits. Results and alarms are published to the AWS IoT Console, Amazon CloudWatch, and Amazon SNS. AWS IoT Greengrass ships with built-in integration, and AWS IoT Device Management can make Detect violations searchable via fleet indexing.
