It’s no secret that the digital advertising marketplace is under sustained attack from increasingly sophisticated bots that divert, steal, and defraud billions of dollars every year. Fortunately, Digital publishers have a number of tools and techniques at their disposal to combat digital ad fraud that go beyond the tradition of log analysis (post mortem) and simple IP blocking.
Then there is the challenge-based approach, such as CAPTCHAs, where the user is asked to prove they are human by solving the challenge. And finally, the reverse proxy approach is the latest way to detect, measure and block fraudulent traffic before it hits the website.
This last approach will be discussed in more details in our next blog post on digital ad fraud prevention using the reverse proxy approach.
