A system for assessing a computer device's state may collect state data about the device, then assess the state with respect to the policy for granting one or more claims. Each claim may be defined by a set of requirements that, if fulfilled, may be used to permit or deny access to a resource, such as an application, network, data, or other resource. A collection engine may reside on the device or other location and may collect requested data, and some collection engines may be extensible with a plugin architecture for expansion. A server may receive information from the device to evaluate claims. Depending on the use scenario, the claim results may be incorporated into communications and passed to an evaluator that may produce an access token which is used to permit or deny access based on the claim results.
