About the Company

TransUnion® is one of the three largest global credit reporting agencies

TransUnion has been enabling trust for over 50 years as a credit reporting agency, with a holistic understanding of consumer identity through decades of stewarding and analyzing data. They have expanded into areas like fraud, marketing, and customer-driven analytics through investments in new data sources and technology, delivering “Information for Good” to allow consumers and organizations to transact with confidence.


Adding TransUnion identity data to banks’ customer review in milliseconds

Banks need to make real-time decisions about new customers looking to open accounts. Acting too slowly can frustrate or even drive away potential customers. Acting too fast can let fraudulent actors through. TransUnion has the data assets and expertise to help, but adding another layer and vendor to the account origination process would slow things down.

Onboard customers with real-time expectations

The pandemic accelerated pressure on TransUnion’s global bank customers, closing branches and increasing consumer expectations for digital efficiency. Bank account origination process was slowed by the need for fraud checks.

Add real-time data to ML fraud models

Providing TransUnion’s leading data and identity solution into banks’ ML models was limited by the physics of data center distance, a minimum 150 milliseconds.


Moving TransUnion’s proprietary data into customer environments demands high security.
