When does Portnox Cloud consume a license?

In this topic, you will find answers to some common questions about Portnox Cloud licensing.

Does a device that is denied access consume a license?
- Yes: If Portnox Cloud places the new device in a restricted VLAN or applies an Access Control List, this device consumes a license.
- No: If a device is denied access to the network completely, it does not consume a license.
Does a device with multiple network interfaces consume more than one license?
- Yes: If the device is not managed by AgentP or Intune, Portnox Cloud has no way to recognize that different network interfaces belong to a single physical device, so each interface consumes one license. This could be an Ethernet interface, Wi-Fi interface, docking station Ethernet interface, etc.
- No: If the device is managed by AgentP or Intune, Portnox Cloud recognizes that the network interfaces belong to the same device and no extra licenses are consumed.
