  1. If you have opted to integrate ShieldSquare API using a SDK or web server plugin or any third party integration, it is required to integrate JS tag also for sophisticated bot detection. 
  2. If you have opted to integrate ShieldSquare to mitigate only against JS based bots to protect your business from Ad fraud, Skewed analytics and other automated threats.
