Software programs make attacking applications easy. Malicious hackers use these programs — called "bots" — to quickly develop, launch, and evolve attacks. These can be simplistic or sophisticated, broad or targeted, and they're often difficult to distinguish from legitimate traffic. Bot management tools are emerging to combat this threat, determining which automated traffic is good or bad and thwarting the bad. Security pros should use this report to understand the capabilities in different bot management market segments and to inform their technology strategies.
