Gartner on Cyber Security

- October 2011

“Threats continue to advance, and network security defenses must evolve to become effective against advanced targeted threats. Enterprises should require vendors to add next-generation intrusion prevention features to network security products.”

“By year-end 2014, 20% of network Intrusion Prevention Systems (IPS) installations … will include next-generation network IPS features.”
