Nozomi Networks OT/IoT Security REST API
Nozomi Networks OT/IoT cybersecurity REST API for critical infrastructure and industrial enterprises to automate asset discovery, vulnerability management, threat detection, and network monitoring across OT, IoT, and IT convergence environments — enabling AI agents to query industrial asset inventory, retrieve security alerts, manage vulnerability findings, and integrate with enterprise security platforms through Nozomi's Guardian and Vantage platforms. Enables AI agents to manage asset management for OT/IoT/IT asset discovery, classification, and inventory query automation, handle alert management for security alert retrieval and severity tracking automation, access vulnerability management for OT device CVE assessment and risk prioritization automation, retrieve network management for industrial network communication and zone monitoring automation, manage query management for custom asset and network data query automation, handle integration management for SIEM, SOAR, and SOC platform data forwarding automation, access report management for security posture and compliance report generation automation, retrieve topology management for network topology visualization data retrieval automation, manage session management for API session lifecycle and authentication automation, and integrate Nozomi with Splunk, Palo Alto, and enterprise security platforms for OT/IoT SOC automation.

⚡ Reliability
Best When
A critical infrastructure operator or industrial enterprise wanting AI agents to automate OT/IoT asset visibility, vulnerability assessment, threat alert integration, and security posture reporting through Nozomi Networks' Guardian/Vantage platform.
Avoid When
ENTERPRISE LICENSE IS REQUIRED: Nozomi serves critical infrastructure enterprises; automated open-developer assumption creates license_required; Nozomi requires enterprise agreement; automated must have Nozomi license. GUARDIAN DEPLOYMENT IS REQUIRED ON-PREMISE: Nozomi Guardian requires on-premise sensor deployment for OT network visibility; automated cloud-only assumption creates no_data for environments without Guardian sensors deployed; automated must deploy Guardian sensors in industrial network segments. PASSIVE NETWORK MONITORING IS PRIMARY: Nozomi primarily uses passive network monitoring to avoid disrupting OT operations; automated active-scan assumption creates operational_risk for active scanning of sensitive industrial networks; automated must use passive monitoring approach. VANTAGE VS GUARDIAN API DIFFERS: Nozomi Vantage (cloud management) and Guardian (on-premise) have different API structures; automated unified-API assumption creates endpoint_not_found for Vantage cloud API calls against Guardian on-premise deployment; automated must use deployment-appropriate API.
Use Cases
- • Inventorying OT/IoT assets across industrial sites for asset management and security baseline automation agents
- • Retrieving OT security alerts and forwarding to enterprise SIEM for unified SOC monitoring automation agents
- • Assessing CVE exposure for industrial devices and prioritizing OT vulnerability remediation for security agents
- • Monitoring industrial network communication for anomalies and policy violations for OT security automation agents
Not For
- • IT endpoint security (Nozomi focuses on OT/IoT/ICS environments; CrowdStrike and SentinelOne serve IT endpoints)
- • Cloud and SaaS application security (Nozomi is for on-premise industrial environments; cloud security uses CSPM platforms)
- • Consumer smart home IoT security (Nozomi focuses on industrial OT and enterprise IoT; consumer IoT needs different tools)

Agent Metadata
Known Gotchas
- ⚠ QUERY LANGUAGE IS NOZOMI-SPECIFIC: Nozomi Guardian uses a custom query language for asset and network data queries; automated standard-SQL assumption creates query_syntax_error for queries not using Nozomi's query syntax; automated must use Nozomi query language for asset and network data retrieval
- ⚠ ALERTS HAVE OT-SPECIFIC TYPES: Nozomi alerts include OT-specific types (protocol anomaly, unauthorized access, malware detection in ICS protocols); automated generic-alert assumption creates alert_misclassification for alert processing without OT-specific alert type handling; automated must handle Nozomi's OT alert taxonomy
- ⚠ ASSET TYPES USE PURDUE MODEL CLASSIFICATION: Nozomi classifies assets using Purdue model levels (Level 0-4); automated flat-classification assumption creates zone_mismatch for security analysis not accounting for Purdue model hierarchy; automated must use Purdue level in asset classification and analysis
- ⚠ GUARDIAN SENSOR DETERMINES DATA SCOPE: Nozomi asset data is bounded by Guardian sensor network visibility; automated complete-inventory assumption creates discovery_gap for assets in network segments not monitored by Guardian; automated must account for sensor placement when interpreting asset inventory completeness
- ⚠ WEBHOOK NOTIFICATIONS REQUIRE SYSLOG OR REST RECEIVER: Nozomi integrations use syslog or REST webhook receivers; automated email-notification assumption creates notification_gap for alert workflows expecting standard email or SMS alerts; automated must implement syslog or REST webhook receiver for Nozomi alert forwarding
