In embodiments of the present invention improved capabilities are described for the detection of uncategorized web-based proxy sites, where an action may be provided in association with access to restricted network locations. In a step A, a network location access request may be received from a computing facility. In a step B, a URL database may be assessed that contains categorized URLs and it may be determined that a URL associated with the network location access request is previously uncategorized URL. In a step C, it may be determined that the URL associated with the network location access request includes a secondary URL. In a step D, the URL database may be accessed that contains categorized URLs and it may be determined that the client is restricted from accessing the secondary URL. In a step E, the action may be provided in association with the network location access request as a previously uncategorized proxy website when steps B, C, and D are all met.
