The DDoS threat landscape is constantly evolving, and to stay ahead of adversaries, ongoing monitoring and analysis are essential to detect how they are modifying their behavior and targets. NETSCOUT monitors the global threat landscape and drills into regional and country-level statistics to ensure that adversaries inform us of near-real-time trends. The country-level analytics featured on this page are automatically generated using our global threat analysis and collection platform, ATLAS, and provide a range of benchmarks for the specified time period, such as the top vectors used in DDoS attacks, top targeted industries, most vectors used in an attack, and total attack frequency.
