FireEye

FireEye protects critical data, intellectual property, and networks against zero-day malware threats such as Web-based malware and botnets that perpetrate cybercrimes at the expense of enterprises and consumers. Their patent-pending technology detects zero-day malware using virtual victim machines to confirm infection attacks without false positives and adding security without loss of IT productivity.
Their solutions eliminate the security holes and long lists of false positives left by legacy network security techniques. FireEyes virtualization technology is used to detect todays advanced Web malware and botnets. FireEye detects stealth malware while eliminating false positives by using their patent-pending virtual victim machine analysis technology that replays suspicious Web and network traffic flows into virtual machines to accurately determine infection status. It offers an extremely precise method for detecting known and zero-day malware so that customers can shut the backdoors into their network (aka infected PCs.)
FireEye offers a global malware analysis exchange network to rapidly share FireEye auto-generated security intelligence about Web malware and its unauthorized outbound destinations. By sharing out this intelligence to local FireEye appliances, customers worldwide benefit from even quicker response times to stop inbound attacks and prevent unauthorized outbound data thefts.
