"Cybercrime remains a growing global problem and attacks against mission-critical and sensitive services or systems that leads to massive data leaks continue to have far-reaching effects. Because there are so many ingenious ways into a network, having sophisticated cyber security measures is not the end game of a defensive prevention strategy," said Ebenezer Obeng-Nyarkoh, Senior Research Analyst, Worldwide Trackers Group. "The key is faster identification and prevention and this is why in the last seven consecutive quarters the deployment of intrusion detection and prevention solutions (IDP) have been gaining traction. Even though this category only represents 4.2% of volume shipments, we are seeing remarkable expansion with the second quarter showing 13.7% year-over-year growth."
