A method for communicating information packets from a first host system operating in a first security domain and in accordance with a non-secure communications protocol, using a dataguard, to a second host system operating in a second security domain different than the first security domain, and where the second host system is also operating in accordance with the non-secure communications protocol. The method may involve: using a first driver operating with the dataguard to interface the dataguard with the first host system; using a first proxy task group operating with the dataguard to interface the dataguard to the first driver and to communicate with the first driver in accordance with a protocol of the first security domain; using a second driver operating with the dataguard to interface the dataguard to the second host system; and using a second proxy task group operating with the dataguard to interface the dataguard to the second proxy task group and to communicate with the second driver in accordance with a protocol of the second security domain.
