IDC MarketScape Worldwide Data Clean Room Technology for Advertising and Marketing Use Cases Vendor Assessment, 2025

Data clean room solutions are no longer a “nice to have.” They’re critical for marketers who want to deliver personalized, person-based campaigns in a privacy-compliant way. The latest IDC MarketScape evaluated the strengths and challenges of data clean room providers serving companies worldwide, and Epsilon was recognized as a Leader.

How did IDC evaluate vendors in the IDC MarketScape?

To evaluate vendors in the IDC MarketScape, IDC looked for the following inclusion criteria:

  • The data clean room must allow data collaboration between two or more parties (while maintaining data privacy)
  • It did not require additional hardware to access privacy features (but this could be an option)
  • It does not require users to encrypt data prior to making it accessible to the data clean room technology (but this could be an option)

To review additional criteria IDC MarketScape considered in its evaluation, download the excerpt above.

According to its assessment, IDC MarketScape stated that Epsilon’s data clean room solution "includes some of the most robust offerings in third party data sets and pre-configured integrations with technology and other parts of the advertising and marketing ecosystem.”

What can data clean rooms offer brands?

At Epsilon, we've seen the value of data clean rooms directly impact our clients and their ability to effectively engage audiences. From cross-channel attribution to audience creation and segmentation, here are some of the features data clean room technology can offer marketers:

Increase quality and scope of known customer data

Any brand is often limited by its own depth and breadth of data because it's specific to how the consumer has interacted with just that one brand. Using a data clean room, brands can take their data and glean deeper insights using partner or third-party data. Once brands incorporate first-party, second-party and premium third-party data, they can better understand who their customers are and market to them more effectively across channels.

Build stronger prospective audiences

A clean room that is equipped with identity and data enables brands to understand their current customers more deeply, build lookalike audiences based on their best customers and transform unknown or unauthenticated customers into known ones.

At Epsilon, our proprietary data gives marketers insights into 250M+ unique U.S. individuals anchored in name and address to create audiences of those most likely to buy. It also helps identify who isn't in market, helping marketers spend media budgets more effectively.

Deliver personalized marketing

With a complete, dynamic and persistent understanding of user behavior, preferences and demographics, marketers can personalize marketing campaigns across owned and paid channels, improving ad engagement and overall campaign performance.

Achieve granular, person-based measurement

Person-based marketing enables person-based measurement. With more information on who they're reaching, marketers can continually learn about current customers and adjust acquisition strategies to find the best in-market people. Each time they deploy a campaign, the measurement helps affirm strong audience strategies and identify those that need adjustment.
