This document discusses the increasing complexity of websites and their interactions with third parties. It explores how early websites in the 1990s were mostly static and brochure-like, interfacing with few third parties, while modern eCommerce sites work with many third parties to provide services like payments, shipping, analytics and more. It also examines how to manage risks from third party service providers, including identifying key providers, building profiles on them, and monitoring them over time. Finally, it discusses how privacy professionals can interact with business units to understand goals, vet new partners, and position privacy as an asset rather than an afterthought.
