Choosing a Nozomi Networks Replacement for Your Environment

The best Nozomi Networks replacement depends on the industrial assets you operate, the visibility you need, and how your security team responds to risk. Use these criteria to compare products against your actual OT environment.

• Define the assets in scope. List PLCs, HMIs, SCADA servers, industrial workstations, network equipment, sensors, and other connected systems. Confirm that each shortlisted product can identify the device types and protocols you use.
• Prioritize safe discovery methods. Industrial equipment may not tolerate active scanning or unexpected traffic. Confirm which discovery methods are available and whether they are appropriate for your production environment.
• Check industrial protocol depth. Review support for the protocols used at your sites, including proprietary or less common communications. Broad device discovery does not necessarily mean deep industrial protocol analysis.
• Separate asset discovery from threat detection. A platform that identifies devices may not provide the same level of industrial threat intelligence, anomaly detection, or incident investigation as an OT-focused security product.
• Evaluate vulnerability context. Determine whether the platform identifies known vulnerabilities, configuration weaknesses, exposed services, and other risk factors. Check how it prioritizes risks when patching is not immediately possible.
• Understand the AI and analytics approach. Vendors may use machine learning for device classification, behavioral analytics for anomaly detection, or threat intelligence to identify known adversary techniques. These approaches address different security needs.
• Measure false positives. Unexpected industrial behavior can result from maintenance, process changes, or legitimate communication. Test how well the platform distinguishes normal operational changes from suspicious activity.
• Review enforcement capabilities. If you need segmentation, network access control, or device isolation, determine whether those functions are native or require integration with other products. Validate policies before enabling them in production.
• Assess incident response workflows. Check whether analysts can investigate an event, identify affected assets, understand communication paths, and determine appropriate containment steps without switching between multiple tools.
• Consider the deployment architecture. Compare on-premises sensors, cloud management, hybrid deployments, and data handling requirements. Air-gapped or highly restricted environments may require a different approach from cloud-connected sites.
• Account for safety and uptime. Evaluate how deployment, updates, active discovery, and response actions affect industrial operations. Test changes in a representative environment and involve OT engineering teams.
• Review SIEM and security integrations. Determine whether the product can send useful alerts and asset context to your SIEM, SOAR, vulnerability management, and incident response systems.
• Match the product to internal expertise. OT security tools may require specialist knowledge to tune, interpret, and investigate alerts. Consider whether your team needs vendor support, managed services, or additional training.
• Compare total cost of ownership. Account for sites, sensors, monitored assets, subscriptions, support, implementation, and required integrations. Compare complete deployment costs rather than a single headline price.
• Validate industry fit. Energy, manufacturing, utilities, healthcare, and building management have different operational requirements. Ask for references and examples relevant to your industry and asset types.
• Run a controlled proof of concept. Use representative network traffic and devices to test discovery accuracy, protocol visibility, alert quality, integration, and operational impact before selecting a platform.
