A system and method for ensuring that machines having invalid or corrupt states are restricted from accessing network resources are provided. A quarantine coordination client (QCC) located on a client machine acquires statements of health from a plurality of quarantine policy clients. The QCC packages the statements and provides the package to a quarantine enforcement client (QEC). The QEC sends the package to a quarantine enforcement server (QES) with a request for network access. The QES passes the package to a quarantine coordination server (QCS) that disassembles the package and passes the individual statements of health to corresponding quarantine policy servers (QPS). The QPSs validate the statements of health and inform the QCS of the result. If the client provided valid statements of health, the QES grants the client access to the network.
