In Q&A from BCS SPA meeting on CEP, friend and colleague Paul Vincent says:
“AFAIK there are no current military systems (as opposed to government intelligence systems) using Commercial Off The Shelf CEP systems, although I recall one commercial product being developed with US military money (your tax $ at work, etc etc).”
Actually, Paul’s statement is slightly misleading. Companies like StreamBase and AgentLogic have their roots in supporting the military. In addition, IBM has a number of event processing related solutions in the military. (There are also others, we suspect.)
It is true, however, that current generation COTS CEP engines do not have the advanced event processing capabilities required for most CEP applications in the military; but as CEP engines advance, this should change.
