ShieldSquare's core power comes from its patented algorithms to uniquely identify Human vs. Good bots vs. Bad bots. ShieldSquare engine is supported with Big Data Analytics which helps it to differentiate between good crawlers like google, Bing, Yahoo etc., and allows them to crawl over your site. When a bot with malicious intent is identified, it immediately sends the appropriate response code (0-Allow, 2-Captcha, 3-Block, 4-Feed Fake Data) through which real time action can be taken accordingly.
