Azure Defender For IoT Pricing And Features Cloud Based Security

Azure Defender for IoT: Pricing and Features

Microsoft Defender for IoT is a cloud-based security service designed to monitor IoT and OT devices. It uses passive, agentless network traffic analysis to identify threats.

This detection process happens without interrupting operations.

EPC Group implements Defender for IoT for clients in various sectors, including:

• Healthcare
• Manufacturing
• Energy
• Government

We ensure compliance with standards such as HIPAA, NERC CIP, and FedRAMP. With 29 years of experience with Microsoft, we deliver expert solutions.

Key facts

• Agentless monitoring — uses passive network traffic analysis, not endpoint agents.
• Detects 1,500+ IoT and OT device types automatically without manual configuration.
• Integrates with Microsoft Sentinel for unified SOC visibility across IT and OT.
• Compliance frameworks supported: HIPAA, NERC CIP, NIST SP 800-82, IEC 62443, GDPR, FedRAMP.
• Pricing: free for up to 1,000 devices per site (OT site license); custom pricing above that threshold.
• EPC Group: 29 years Microsoft consulting, 11,000+ enterprise engagements.

What is Azure Defender for IoT?

Azure Defender for IoT is a security monitoring service that operates without an agent. It is specifically designed for IoT and OT (operational technology) environments. This service safeguards devices that traditional IT security tools often overlook. These devices include:

• IoT devices
• Operational technology devices
• Legacy systems

• PLCs
• SCADA systems
• Medical devices
• Industrial sensors

Defender for IoT differs from traditional IT security tools. While many rely on endpoint agents, Defender uses passive network traffic analysis.

This approach allows it to:

• Monitor network communications
• Operate without disrupting ongoing activities
• Require no changes to devices

Key Features

• Automatic asset discovery — Identifies 1,500+ IoT and OT device types by passively analyzing network traffic. No manual inventory required.
• Continuous threat monitoring — Behavioral analytics detect anomalies, known attack patterns, and zero-day vulnerabilities in real time.
• Vulnerability assessment — Identifies unpatched firmware, weak credentials, open ports, and unauthorized protocol usage.
• Microsoft Sentinel integration — Sends alerts to Sentinel for unified IT/OT SOC investigation and automated incident response playbooks.
• Purdue Model awareness — Understands Level 0–5 OT network architecture for accurate alert prioritization.
• Air-gapped environment support — Works in fully disconnected environments using on-premises sensors with local management.

Regulatory Compliance Support

Defender for IoT helps organizations meet six major compliance frameworks. Each framework has specific controls the service addresses:

• HIPAA Security Rule — Network monitoring, access controls, and audit logging for medical device environments.
• NERC CIP — Electronic security perimeters and system security management for energy and utility OT networks.
• NIST SP 800-82 — Industrial control system security guidelines for government and critical infrastructure.
• IEC 62443 — Industrial automation security standards for manufacturing and process industries.
• GDPR — Data protection for IoT-collected personal data in EU-regulated environments.
• FedRAMP — Federal cloud security requirements for government IoT deployments.

Azure Defender for IoT Pricing

Defender for IoT uses a site-based pricing model. Sites are defined by physical location or network segment:

• Free tier — Up to 1,000 committed devices per OT site at no cost.
• Paid tier — Custom pricing above 1,000 devices. Contact Microsoft or EPC Group for a site-based quote.
• Enterprise IoT (IT network devices) — Microsoft 365 E5 or Microsoft 365 E5 Security license covers Defender for IoT for enterprise IoT devices on IT networks.

Deployment Modes

Defender for IoT offers two deployment architectures based on connectivity:

• Cloud-connected sensors — OT network sensors connect to Microsoft Defender for IoT in Azure. Recommended for internet-connected sites. Real-time threat intelligence from Microsoft's global threat database.
• Air-gapped / locally managed sensors — Sensors operate fully on-premises with no connection to Azure. Required for classified or completely isolated environments. Threat intelligence updates delivered offline.
