Network monitoring appliance maker Solera Networks was acquired by Blue Coat systems in May. The firm showed off the latest components of its security analytics and advanced threat protection platform at Black Hat. The company's appliance acts as a DVR for the network and competes against RSA NetWitness. Both appliances are coveted by forensics teams and incident responders who use them to conduct deep analysis on systems following a breach. In recent years, the firms have touted the ability to detect attacks in real time.
