Unit21, an AI risk infrastructure platform focused on fraud prevention and AML monitoring, has joined forces with Corelation, the core processing provider behind KeyStone and over 300 credit union clients.
The tie-up gives credit unions on KeyStone a single environment to detect, investigate, act on and report fraud and AML risk.
The integration runs both ways. Member, account, card and transaction data moves from KeyStone into Unit21, where it feeds detection and investigation. Analysts can then respond directly within KeyStone using Corelation’s KeyBridge API, freezing cards, halting payments and applying holds without exiting the case they are working on.
Until now, credit union staff have often spotted suspicious activity in one tool, then had to sign in to the core system separately, search for the member a second time and manually re-enter account details. Under the new arrangement, evidence, decisions and actions sit on one record, with the audit trail generated as soon as the analyst intervenes.
Both customer bases stand to benefit. Corelation clients can now route their data into an AI-native platform covering fraud prevention, AML transaction monitoring, case management and filing, using a feed that Corelation itself builds and maintains.
Meanwhile, Unit21 customers running KeyStone can issue card blocks, card activations, stop payments and check holds from within a Unit21 case, with each request, response and user action recorded next to the supporting evidence. The combined offering pairs Corelation’s person-centric core with Unit21’s adaptable detection engine, creating one defensible process that runs from a flagged transaction through to a protected account and a filed SAR or CTR.
On the technical side, Corelation provides a dedicated Unit21 AML Extract, which each credit union’s administrator or data team sets up within its own KeyStone environment. Following an initial historical load, the extract pushes incremental updates covering entities, joint account holders, accounts, cards and transactions roughly every five minutes, giving Unit21 a near real-time picture of member behaviour.
Unit21 applies the credit union’s self-service rules and AI Agents to this data and returns any required actions to KeyStone via the KeyBridge API. Credit unions may also link their digital banking platform to Unit21 to support real-time decisions on logins, profile changes and payments.
Unit21 positions the deal as part of its broader commitment to the credit union and community banking market. The company will also attend and sponsor the Corelation Executive Forum in Chula Vista, California, next week.
Unit21 CEO Tyler Allen said, “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.”
Corelation chief revenue officer Tim Maron added, “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.”
