What does Passbeam actually do?
Passbeam does two jobs. It runs a certificate authority for each of your clients, and it's the RADIUS server your switches, access points and VPN gateways ask when a device tries to connect. That's 802.1X, over RADIUS or RADSec.
Devices connect with a certificate instead of a password. Every connection checks that the certificate belongs to this client, hasn't expired and hasn't been revoked. When an account is disabled in Entra ID, Passbeam revokes its certificates, so that person's devices stop connecting. There's no shared Wi-Fi password to give out or to leak.
It works the same for Wi-Fi, wired and VPN. One certificate gets a laptop onto the Wi-Fi, onto a switch port and through the VPN from home. Passbeam can also put each device or person on its own VLAN.
Printers, cameras, door controllers and building management systems can have certificates too, from the same authority. A client can be just those, with no Entra ID behind it.
