Embodiments are directed to managing access to network resources. Mesh agents for an overlay network may be provided. If a client requests access to a resource, a first mesh agent configured to provide the client with ingress to the overlay network may be determined. If a security engine validates the request received from the first mesh agent, a route from the client to the resource may be determined. A secure tunnel may be generated between the first mesh agent and a last mesh agent based on forwarding the request to mesh agents on the route. If the request is provided to the last mesh agent credential information for the resource may be provided to the last mesh agent and the last mesh agent, the request and the credential information may be employed to access the resource.
