A method for packet inspection in a computer network includes receiving a plurality of network streams from a plurality of client systems at a first load balancer; allocating the network streams across a proxy instances; and inspecting and filtering the network streams by the proxy instances. The method further includes forwarding the filtered network streams to a second load balancer; allocating the filtered network streams to a plurality of application instances; and processing and responding to the network streams at the application instances. The method still further includes inspecting and filtering the responses to the network streams by the proxy instances; and forwarding the response to the client systems.
