Choose a deployment model
Listed products run through web and API access, self-hosted installations, and Linux, Windows or Android environments. Match the deployment choice to how your team manages infrastructure and where staff need access.
Confirm the specific product's supported platforms before you commit, especially when you need an Android app or a self-hosted installation.
Check discovery and monitoring features
Look at how each product handles discovery, SNMP data and flow analysis. These capabilities determine how the software finds devices and presents network activity.
