Methods and systems for regulating services provided by a first computing entity, such as a server, to a second computing entity, such as a client are described. A first entity receives a request for a service from a second entity over a network. The first entity determines whether the second entity has a trusted agent by examining an attestation report from the second entity. The first entity transmits a message to the second entity. The trusted agent on the second entity may receive the message. A response is created at the second computing entity and received at the first entity. The first entity then provides the service to the second entity. The first entity may transmit an attestation challenge to the second entity and in response receives an attestation report from the second entity.
