# Do I need to install anything?

You choose the deployment: a single SPAN/TAP port on your switch watches a whole network segment and counts as one device, or install the NetSenX agent on the specific hosts you choose. Both are documented; no kernel modules. On Linux the installer only installs a package whose signature matches the NetSenX release key, and refuses anything else; macOS agents are set up together with NetSenX support.
