Nozomi Networks vs Siemens

About Nozomi Networks

Nozomi Networks sells a platform for OT and IoT visibility and security that combines visibility from the endpoint to the air with continuous monitoring and AI-powered analysis. The Nozomi Networks platform is built for complex industrial, commercial and critical infrastructure environments. Nozomi Networks states that industrial networks can contain hundreds or even thousands of OT and IoT devices from a variety of vendors, many of which are insecure by design.^[8][15]

The Nozomi Guardian security sensor passively observes and analyzes local network traffic to provide OT and IoT asset visibility. Nozomi Guardian sensors can be deployed as hardware appliances, virtual machines, embedded devices or containers. Nozomi Guardian sensors receive and process data from other Nozomi security sensors and collectors and send it to either an on-prem Nozomi Central Management Console or the Nozomi Vantage cloud management platform. By combining host-based detection and threat prevention with lightweight network sensing, Nozomi Arc extends coverage to protect assets where Nozomi Guardian and Guardian Air sensors cannot reach. Arc Embedded is a security sensor developed with OEMs to run inside industrial controllers at Purdue levels 0-1. Arc Embedded monitors east-west communications, process variable readings and controller logic changes to detect threats and anomalies. Nozomi Networks offers low-resource sensors that collect asset and network data in remote locations and send it to Guardian for further analysis. Nozomi Networks wireless sensors detect Wi-Fi, Bluetooth, Zigbee, LoRaWAN, Drone RF and other wireless protocols used in OT and IoT environments. Nozomi Networks offers endpoint sensors for Windows, Linux and MacOS endpoints.^{[1][3][9][10]}

Nozomi Central Management Console (CMC) is a physical or virtual appliance that manages hundreds of Guardian network security sensors from a single location. Nozomi CMC collects, aggregates and analyzes data across sites to provide consolidated visibility, management and reporting. Nozomi CMC can be deployed on-prem, at the edge, in a customer cloud or paired with Vantage SaaS. Nozomi CMC enables Guardian sensor management for everything from air-gapped OT networks to globally distributed enterprises. Vantage IQ can take the role of a SOC analyst, OT engineer, CISO or any role needed through custom Personas. The AI assistant covers threat investigation, vulnerability prioritization, compliance and board reporting.^[2][11]

The Nozomi Networks platform combines endpoint-to-air sensors, passive and active data collection, OT/IoT protocol support and third-party IT asset data to provide an OT and IoT asset inventory. Nozomi Asset Intelligence is a subscription feed that enriches data collected by passive and active discovery and third-party ingestion methods. Nozomi Asset Intelligence uses artificial intelligence curated by Nozomi Networks Labs data engineers to enhance cyber device profiles with missing information. Asset Intelligence can enrich basic profiles with data from matching assets such as image, detailed description, asset type, vendor, product name, OS and lifecycle. On deployment, the Nozomi Networks platform begins monitoring device communications in learning mode, down to process-level variables. In protection mode, the platform uses behavior analytics to monitor and alert on suspicious events that deviate from baselines.^{[8][10][11][12][14]}

The Nozomi Networks platform automatically identifies and scores open OT and IoT vulnerabilities in devices. Nozomi Networks collects vulnerability information through network monitoring, endpoint monitoring and smart polling. Nozomi Networks Labs curates OT- and IoT-specific threat intelligence used to identify early indicators of compromise in sensitive and unpatchable environments. Nozomi Networks delivers a network monitoring solution built for OT, IoT and the industrial operators that rely on them. The network monitoring solution uses deep packet inspection that covers a wide range of industrial, IoT and IT protocols. The Nozomi Networks platform includes dashboards, query capabilities, playbooks and forensic tools to help coordinate remediation efforts across teams. The Nozomi Networks platform measures risk with multi-factor scoring at the asset, zone, site and enterprise levels.^[8][13]

The Nozomi Networks platform enables data center administrators to gain visibility into their infrastructure and diagnose threats and anomalies. For data centers, the Nozomi platform provides an inventory of OT and IoT assets, risk-based vulnerability management, continuous threat and anomaly detection, and AI-powered SOC assistance. Nozomi Networks states that large data centers increasingly operate their own substations and that those substations must be secured in compliance with strict cyber regulations for electric utilities such as NERC CIP in North America. The Nozomi Networks platform is built to protect OT and IoT networks in commercial, residential and industrial environments from cyber and operational risk.^[14]

Nozomi Networks says its global ecosystem of partners has been Nozomi Networks certified to deploy on-prem, as part of a hybrid network, with cloud resources, or manage it all for the customer. Nozomi Networks partner services range from OT and IoT network assessments with solution design, deployment, tuning and support to managed platform, detection, operational analytics and response services.^{[1][6][11][15]}
