ShieldSquare gives you the flexibility of taking action against bots through options such as to show Captcha, redirect the bot to a dummy page,feeding fake data or implementing your own business logic like asking for credentials or SMS OTP. Please note, ShieldSquare engine responds to every request by sending a response code. The implementation logic to show Captcha/Block/Feed Fake Data etc. has to be carried out at your end, depending on the response code.
