Valuable Features

Nozomi Networks provides real-time visibility, powerful network visualization, and AI-based detection. It integrates easily with third-party systems enhancing visibility in network security, especially for OT and IoT environments. Features like asset tracking, threat intelligence, anomaly detection, and comprehensive dashboards support stability and usability. Users value its asset and vulnerability management capabilities, detailed traffic analysis, and versatile queries, benefiting threat detection with detailed information such as CVE risk scores and live data insights.
  • "The best feature of Nozomi Networks is that it has built OT-oriented protocols such as OPC UA, DNP3, Modbus, and Siemens S7, and for these protocols, Nozomi Networks identifies them very perfectly."
  • "I believe it is the best."
  • "It brings visibility into the OT environment because most of the enterprises only have methods to check their IT environment."

Room for Improvement

Nozomi Networks needs to enhance its AI capabilities and improve integration with SOC and SOAR systems. Users suggest more customizable configuration options and free availability of ARP agents. They also desire better threat intelligence, support for more PLCs, improved proof of concept, and reduced pricing. Customers find the licensing structure costly and exporting data limited. There's feedback about insufficient programmable logic controller support and the need for an integration library. Users often compare Nozomi Networks unfavorably with Dragos in threat intelligence.
  • "Regarding the functionality of Nozomi Networks, the query syntax is very complicated. The syntax of the queries is very complex, so sometimes you will not get what you want."
  • "On the negative side, I believe their AI, which is IQ, could be more improved."
  • "Proof of concept could be improved. It could be more tangible to the customer and the end users to have a video presentation or something like that."

ROI

Nozomi Networks significantly enhanced threat detection and visibility for users, resulting in reduced downtime and operational efficiencies. The automation features led to time and cost savings by streamlining processes and minimizing manual intervention. Improved asset management provided clear insights, facilitating better decision-making and quick response to risks. This elevated security posture helped avoid potential losses from cyber threats, demonstrating clear financial benefits. Customer satisfaction improved due to the stable network environment provided by Nozomi Networks.

Pricing

Enterprise buyers find Nozomi Networks' pricing reasonable and moderately priced. Users note it is cheaper than Claroty, making it a cost-effective option considering its features. It is neither the cheapest nor the most expensive solution, providing a balanced choice for businesses. Monthly licensing options offer flexibility, yet it's advised to plan for budgets on the higher end of the market if considering Nozomi Networks or competitors like Claroty.
  • "The solution's pricing is good and cheaper than that of Claroty."
  • "I have not seen any competition in terms of pricing, and it is quite reasonable."

Popular Use Cases

Nozomi Networks is primarily used for intrusion detection in OT, IoT, and automation environments. Users deploy it on cloud, on-premises, and hybrid infrastructures for OT visibility and asset management. It aids in vulnerability scanning, risk quantification, and managing asset inventories in energy and industrial sectors. Service providers leverage its dashboard, Vantage, Guardian, and CMC for sharing alerts, notifications, and vulnerability management details, identifying unauthorized communication, and mitigating risks.

Service and Support

Users find Nozomi Networks' support team responsive and helpful, though some feel it could be more proactive and efficient. Many appreciate their local support's frequent visits and readiness to assist. Some users with sufficient security knowledge have not needed support. While ticket resolutions are provided, communication might be slower. An increase in direct communication and campaigns is desired for added value. Overall, users rate their service highly, appreciating the knowledge and documentation available.

Deployment

Users found Nozomi Networks's initial setup to be mostly easy and smooth, with installation typically taking a few hours to two days. Basic configurations are straightforward, though custom setups can be more complex. Many appreciated assistance from Nozomi staff during demos.

Nozomi Networks Reviews Summary
Author infoRatingReview Summary
Senior Team Member In Engineering And Cybersecurity at Mindsprint4.5As a service provider, I find Nozomi Networks excellent for detailed asset and vulnerability management across many sites. Its analytics are valuable, though AI and customer service need improvement. It's a top choice for critical environments.
Sr. Storage And Backup Engineer at a comms service provider with 51-200 employees4.5I rate Nozomi Networks highly for its OT protocol identification, network visualization, and easy setup. Support is excellent. However, I suggest improving its AI/ML for unknown malware detection and simplifying its complex query syntax.
Country Sales Manager at a computer software company with 51-200 employees4.0I’ve used Nozomi Networks for four years as an on‑prem OT/IoT IDS, valuing real-time visibility, asset tracking, ML anomaly detection, scalability, and strong support. Deployment is smooth, but occasional crashes occurred. I want stronger SOC/SOAR integration and threat intelligence.
Security Specialist at a tech consulting company with 51-200 employees4.5We use Nozomi Networks for asset management and risk assessment in our operational technology environment, valuing its visibility and versatility. While costly add-ons could improve data collection, we switched from Tenable OT Security for better scalability and integrated reporting.
Business Development Account Manager at Xenia Network Solutions4.5I find Nozomi Networks valuable for its clear visibility of network traffic and cost-saving benefits. While its pricing could improve, the platform significantly enhances security by reducing technical resource needs and streamlining operations across all network devices.
Production Quality Engineer Specialist at a manufacturing company with 10,001+ employees3.5I find the network visualization feature of Nozomi Networks valuable for security operations and asset management, though it could benefit from more customizable configuration options. Creating custom queries is currently time-consuming, and additional easy configuration options would be helpful.
OT Cybersecurity Manager at Whirlpool Corporation5.0I find Nozomi Networks to be an easy-to-use and powerful tool, especially for network visualization. It effectively monitors and manages OT assets while helping to identify vulnerabilities and critical issues. I'm satisfied with its performance and features.
I Specialist Security Engineer I at Platin Bilisim4.5I use Nozomi Networks for vulnerability scanning in energy firms, finding its time capsule feature valuable. I've considered alternatives like Elastic and Curator. There's potential for improvement in on-premises AI, and it's too early to discuss ROI.
