Regarding the "Ad Security" section that includes HUMAN Security as "Sell-Side" and Confiant as "Buy-Side"- Having worked at Human Security, there are three media solutions, one is a product that provides invalid traffic decisioning pre-bid, one that provides invalid traffic analysis post-bid, and the clean.io acquisition that protects publishers from malvertising. That being said, this is both buy and sell side. From the Confiant website, it looks like it is malvertising only, which would be more sell-side protection.
