Native KeyStone integration gives fraud and AML teams the ability to detect suspicious activity in Unit21 and act on it in their core, from the same case

Unit21, the leading AI Risk Infrastructure platform for fraud prevention and AML monitoring, today announced a partnership with Corelation, Inc., the core processor behind KeyStone and more than 300 credit union clients.

The integration connects KeyStone to Unit21 in both directions: member, account, card, and transaction data flows from KeyStone into Unit21 for detection and investigation, and analysts take action back in KeyStone through Corelation's KeyBridge API, blocking cards, stopping payments, and placing holds without leaving the case. Credit unions on KeyStone can now detect, investigate, act on, and report fraud and AML risk in a single system.

The integration closes a gap credit union teams have long bridged by hand. An analyst could see the fraud in one system but had to log in to the core to stop it, look up the member again, and re-key the account. With this partnership, the evidence, the decision, and the action live on the same record, and the audit trail is written the moment the analyst acts.

The partnership provides a two-way value exchange across both customer bases.

• For credit unions using Corelation, the integration brings Corelation data into a modern, AI-native platform for fraud prevention, AML transaction monitoring, case management, and filing, on a data feed Corelation builds and supports.
• For Unit21's credit union customers on KeyStone, investigations no longer stop at the edge of the platform. Card blocks, card activations, stop payments, and check holds are sent to KeyStone from inside the Unit21 case, with every request, response, and user action logged alongside the evidence that justified it.

Together, the companies are pairing a person-centric core built for credit unions with Unit21's flexible detection platform. The result is a single, defensible workflow from a suspicious transaction to an investigated case to a protected member account to a filed SAR or CTR.

"Fraud moves at the speed of real-time payments, and credit unions can't fight it with next-day files and a second login. Together with Corelation, we're giving credit unions a way to catch fraud, stop it in the core, and file on it, all from a single case. That means fewer dollars lost, fewer members harmed, and fraud teams that finally get ahead instead of cleaning up."

- Tyler Allen, CEO, Unit21

How it works

Corelation delivers a dedicated Unit21 AML Extract, configured in each credit union's KeyStone environment by its own administrator or data team. After an initial historical load, the extract sends incremental changes to entities, joint account holders, accounts, cards, and transactions about every five minutes, giving Unit21 a near real-time view of member activity.

Unit21 runs the credit union's self-service rules and AI Agents on that data, and when action is needed, sends it back to KeyStone through the KeyBridge API. Credit unions can also connect their digital banking platform to Unit21 for real-time decisions on logins, profile changes, and payments.

"Our clients choose KeyStone because it puts the member at the center of everything. Partnering with Unit21 extends that to fraud and BSA, giving credit unions a modern way to protect members and act on risk directly from their investigations."

- Tim Maron, Chief Revenue Officer, Corelation
