eero supports VPN passthrough. This means you can use another routing device with VPN in front of your eero, and eero will be able to pass that VPN traffic. Also, if you have a VPN service set up on your device, eero can pass that traffic as well.
At this time, eero doesn't actively manage your VPN. However, with eero Plus, members get an account for Guardian VPN included with their membership. With Guardian VPN, eero Plus members get up to five accounts and can install the Guardian VPN tool on an unlimited number of supported devices.
