NETSCOUT's Active Level Threat Analysis System (ATLAS™) compiles DDoS attack statistics from most of the world's ISPs, large data centres, and government and enterprise networks. This data represents intelligence on attacks occurring in over 190 countries, 550 industries, and 50,000 autonomous system numbers (ASNs). NETSCOUT's ATLAS Security Engineering and Response Team (ASERT) analyses and curates this data to provide unique insights in its biannual report.
