If the budget allows, the company/organization can have a local network (or just a separate, individual computer) and a separate research network for Internet/global communication purposes. This way, confidential materials can only be accessed locally, increasing both electronic and physical security. Only the data physically copied/tranferred to the research network will be globally available (through other firewalls, of course), and data can be checked for errors or viruses before loaded to the local network.
