Last Tuesday, the ICO held a fact-finding forum with various brands, ad tech industry executives, privacy campaigners and lawyers.  Key focuses were companies’ treatment of sensitive, “special category” data and the often substandard contractual agreements to protect how bid-request data is shared between vendors.

Following their insightful June 2019 report on the same topic, it looks like the ICO isn't taking its foot off the pedal any time soon when it comes to scrutinising the ad tech industry.  The ICO tends to publish a summary report of its fact-finding forums, so fingers crossed we'll see some output in the coming weeks.
