Key Platform Features 

Network Visualization 

Get a complete view of communicating devices and traffic patterns to build a visualization map that can accelerate research and quickly identify anomalies and incidents. 


Workbooks prioritize remediation efforts by highlighting the most critical endpoint vulnerabilities. 

The first phase of cybersecurity maturity is understanding what is on your network and anticipating where risks may arise. 

Nozomi Networks provides visibility to all your endpoints with deep data collection that can expose vulnerabilities and highlight where to focus risk management efforts. Visualize your device connections and traffic patterns to facilitate research and compliance efforts. Anticipate security threats before they impact your operations, while reducing risk and compliance efforts.">
