In September 2018 we began reporting ad fraud statistics for the programmatic ad space based on monthly data we collected. We then published our first Quarterly Ad Fraud Report with data from Q4, 2018. We're continuing this coverage with our Q2 2019 Ad Fraud Report, which includes data on which devices, browsers and operating systems are being used most for fraud and what areas of the world fraudulent traffic is originating from.

Keeping the industry updated on the latest data and threats we see in the digital ad community is important, so we we'll be publishing regular updates on ad fraud percentages as well as which countries, devices, browsers and operating systems are being taken advantage the most for ad fraud schemes. Stay tuned.
