- Alerts and Incidents
- Discovery
  - Discovery overview
    Discovery identifies previously undetected network devices. It sends protocol-specific broadcast messages to devices and examines the replies. The sensor repeats this process at predefined intervals transmitting diverse messages based on the devices.
  - Strategies
    - Strategies overview
      Discovery strategies are network-based methods that identify devices across subnetworks using broadcast messages, enhancing visibility in Nozomi Networks environments.
