Examples relate to a network endpoint device of a first network infrastructure that facilitates remote attestation of the network endpoint device. In same examples, the network endpoint device comprises a trusted platform module and a processor that implements machine readable instructions that cause the network endpoint device to: receive a connection request from a computing device residing a second network infrastructure external to the first network infrastructure, the request comprising s security challenge; determine, based on a configuration of the network endpoint device, whether it can access information stored in the trusted platform module; and responsive to determining that information in the trusted platform module can be accessed, facilitate connection of the computing device to the network endpoint device by accessing the information and responding to the security challenge.
