Microsoft Azure has released a tool to discover and map data residing in all systems, within and outside of Azure itself. Azure Purview scans metadata and adds data sensitivity levels that help enforce limits based on privacy or other considerations. Data discovery is a key challenge for both Customer Data Platform implementations and privacy management.

Privacy concerns may also be hitting Facebook where it hurts. This DigiDay report says that media buyers are being told to shift budgets elsewhere. Privacy is one possible reason; high ad costs, poor ad tools, and more competitive options are others. Color me skeptical, although this Dentsu report says Facebook growth shows some weakness.

We have a full basket of retail news today, Dear Reader.  First up is NielsenIQ, which just launched a solution to help retailers run their own media networks with tools to build targeted audiences, manage ads and offers, and measure results.  The same tools would probably support retailers’ own promotions, but retail media networks are a much hotter topic right now.
