This attacker is all about stealing vital information from America\u2019s top companies and agencies -- formulas for new drugs and designs for cars to name a few. This isn\u2019t about the hacker down the street. Its cyber warfare for financial gain.\t\t\t\t\tGeneral Dynamics Advanced Information Systems started its incident response and forensics group protecting complex government networks and evolved this experience for the commercial market. This group has a resume that boasts it\u2019s managed more than 2,500 investigations and solved some of the world\u2019s largest commercial network intrusions.\t\t\t\t\tTogether, Fidelis will be able to use insights from this General Dynamics team to push the envelope on advanced threat defense innovation, bringing to market even more comprehensive products to protect against the many layers of threats \u2013 including offering more visibility to expose threats that have burrowed deep inside networks.\t\t"Being prepared and having the right intelligence and technologies is critical for organizations to mitigate and respond to cyber threats in real time," said Peter George, president and chief executive officer for Fidelis Security Systems. "The combination of Fidelis Security Systems' products and General Dynamics' cyber services and incident response capabilities will strengthen our customers' ability to achieve situational awareness to protect and defend their networks."\tFidelis Security Systems employs approximately 70 people at locations in Waltham, Mass., and Bethesda, Md.\tThe acquisition has been approved by the boards of directors of both companies. General Dynamics expects the transaction to be completed in the third quarter of 2012.
