Succeed in a cookieless world

Identifiers like third-party cookies were never made to last—which is why we built our identity strategy on a strong foundation of deterministic data and consumer privacy designed to outlast industry changes.

How we’re future-proofed for a cookieless world

14,000+ publisher relationships

Publishers' first-party data is critical. We have direct relationships with a growing list of high-quality publishers.

Publisher data links to our CORE IDs

By linking publishers’ first-party data such as hashed emails to our 200+ million deterministic CORE IDs, we recognize real people across the open web and serve them personalized ads in real time—no third-party cookies required.

Years of preparation

Epsilon saw the flaws of third-party cookies years ago. We designed CORE ID with built-in privacy starting back in 2007 and have been strengthening our identity graph with direct publisher relationships since 2012. This early and resilient approach is why our identity has greater scale and accuracy than other solutions.
