IT security teams within federal government agencies and their contractors face a daunting series of challenges in securing their networks against modern malware intrusions, including advanced persistent threats (APTs), advanced targeted attacks (ATAs), polymorphic malware, and file-less intrusions. Their networks and infrastructures are prime targets for nation-states, political agitators, organized criminals, and other hackers eager for access to truly critical content, be it for espionage purposes, to cause political embarrassment, or to reap financial gain. Furthermore, they are subject to a myriad of regulations from oversight and standards-setting organizations, both U.S. and international.
