Reveal operational blind spots
Discover communicating assets and map their connections. Extend visibility across wired, wireless, endpoint and remote environments with the right sensors.
Nozomi Networks · AI-Powered OT, IoT & CPS Security
See your OT environment. Detect operational risk. Protect what must keep running.
Nozomi Networks gives security and operations teams real-time visibility across OT, IoT and cyber-physical systems. Purpose-built monitoring, AI-powered analysis and OT threat intelligence help expose risk early while respecting the availability and safety requirements of critical operations.
Business outcomes
Protect operations without treating OT like ordinary IT
Monitor without disrupting production
Use passive network monitoring to gain deep OT and IoT visibility without generating additional traffic on critical control networks.
Detect cyber and process anomalies early
Baseline normal behaviour, then identify suspicious communications, malware, unwanted operations and unusual process values.
Prioritise the risk that matters
Combine vulnerability intelligence with asset criticality and operational context so teams can focus on practical risk reduction.
Unify security across sites
Centralise visibility, alerts and risk across plants, facilities and remote locations through cloud or on-premises management.
Demonstrate resilience and compliance
Track risk reduction with dashboards, benchmarks and audit-ready evidence for leadership, operations and assurance teams.

OT security operating cycle
Turn operational visibility into measurable risk reduction
Nozomi brings asset, network, vulnerability and threat context together so security and operations teams can make informed decisions without losing sight of safety and availability.
Discover
Continuously identify OT, IoT and cyber-physical assets across wired, wireless, endpoint and remote environments.
Understand
Map communications, protocols, roles, firmware, process variables and normal operational behaviour.
Prioritise
Connect vulnerabilities and exposures with asset criticality, operational impact and compensating controls.
Detect
Identify behavioural anomalies, malicious activity, suspicious communications and unusual process conditions.
Respond
Give IT and OT teams the evidence, workflow and remediation guidance needed to act safely and quickly.
Nozomi platform
Visibility from the network to the endpoint and the air
Choose a cloud or on-premises management model, then extend coverage with sensors suited to the operational environment.
Vantage and CMC
Unify OT and IoT visibility, risk and security operations across sites through cloud-based Vantage or an on-premises Central Management Console.
Guardian
Observe industrial network traffic without adding operational traffic, then build asset inventories, topology maps and behaviour baselines.
Arc
Extend asset and threat visibility to critical or isolated endpoints, including host activity, removable media and nearby network devices.
Guardian Air
Monitor wireless frequencies used in operational environments and identify connected assets, rogue infrastructure and attack surfaces.
OT security capabilities
Purpose-built context for cyber-physical environments
Real-time asset inventory
Build an inventory from observed communications, including device types, firmware and protocols. Optional Smart Polling adds approved active queries for deeper asset details.
Dynamic network visualisation
See devices, zones, links, traffic patterns and dependencies to support segmentation and incident analysis.
AI-powered behaviour baselining
Learn normal device, network and process behaviour to identify suspicious changes. Optional Vantage IQ adds AI-assisted alert correlation, risk prioritisation and natural-language investigation in the Vantage cloud platform.
OT threat intelligence
Use indicators and research curated for OT and IoT environments to identify emerging threats and vulnerable assets.
Exposure management
Prioritise vulnerabilities and weaknesses using asset criticality, reachability, exploitability and operational context.
Incident investigation
Bring alerts, asset details and process context together. Time Machine network-event replay helps teams examine the sequence around an incident and support root-cause analysis.
IT and OT integration
Connect operational telemetry and findings with existing SIEM, SOAR, ticketing and security workflows.
Compliance evidence
Use dashboards, benchmarks and audit-ready reporting to support programmes aligned with standards such as ISA/IEC 62443.
Apexagen-managed OT security deployment
From visibility to a working OT security operation
We plan monitoring around your critical processes, coordinate deployment with OT owners and establish a behaviour baseline. Alert tuning, agreed escalation paths and response ownership connect engineering, operations and security teams.
Start with an OT visibility assessment
Build a picture of your observed assets and communications, understand priority risks and agree practical next steps. We scope the assessment around your sites and operational constraints.
- Observed asset inventory and communications map
- Prioritised vulnerability and exposure findings
- Coverage gaps and practical next steps
OT security questions
Nozomi Networks and OT security FAQ
What does an OT security platform monitor?
It monitors assets, industrial communications, protocols, vulnerabilities, process behaviour and security events across operational technology, IoT and other cyber-physical systems.
Can Nozomi monitor an industrial network without disrupting production?
Nozomi Guardian can passively observe mirrored network traffic or network taps without generating additional traffic on the monitored industrial network. The final architecture is reviewed against the site’s safety, availability and change-control requirements.
How does Nozomi use AI for OT security?
Guardian uses AI-powered analytics to baseline normal device, network and process behaviour and identify unusual activity. Optional Vantage IQ for the Vantage cloud platform adds alert correlation, risk prioritisation, remediation guidance and natural-language questions to support investigation.
Does passive monitoring discover every OT device?
Passive monitoring discovers devices communicating on the monitored network segments. Coverage depends on traffic and sensor placement. Optional Smart Polling uses approved active queries for deeper asset information; endpoint and wireless sensors can extend visibility where needed.
Can Nozomi identify vulnerabilities in legacy OT assets?
Nozomi can associate discovered assets with vulnerability and threat intelligence, then use operational context to support prioritisation. Remediation decisions still need to consider safety, vendor support and maintenance windows.
Does Nozomi support air-gapped or on-premises environments?
Yes. Guardian sensors and the Central Management Console support on-premises architectures, including environments with strict cloud connectivity or data-residency requirements. Deployment design depends on the required functions and network restrictions.
Can Nozomi cover multiple plants or operational sites?
Yes. Vantage provides cloud-based central management across sites, while the Central Management Console supports centralised on-premises management. Sensors and collectors can be distributed according to the network architecture.
Can Nozomi integrate with our existing SOC tools?
Nozomi supports integrations with common security, IT service management and response platforms. Apexagen confirms the required data flows, supported integrations and operating responsibilities during design.
