- Frequently asked questions

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 (requires the device ID SAN value), Portnox Cloud recognizes that the network interfaces belong to the same device and no extra licenses are consumed.
  Note: To check if the network interfaces are correctly associated with the same Intune-managed device, see this troubleshooting topic: How to check if two network interfaces belong to the same Intune-managed device?.
