Web Challenges

Web Challenges are several technologies used to distinguish between real humans and bots in general, or DDoS bots in our context. There are several types of challenges. The best-known one is the CAPTCHA, which is very intrusive, but there are other, less-intrusive transparent challenges such as Cookie Validation or the JavaScript Challenge. Web Challenges are considered one of the most effective mitigation layers against DDoS application attacks.
