DoubleVerify is an adfraud and brand safety tracker. Basically, they ensure that your ads are displayed to people and not on questionable content if you dont want to. Most agencies and large direct advertisers add this 3rd party to ensure actual humans are seeing the ads, and thus the advertiser is paying for “good” eyeballs instead of “bad”. It’s essentially a 3rd party checking that the ad network doesn’t do anything naughty, which some sites have done in the past.
