How Alkami Clients Stopped $263 Million in Fraud, and What Credit Unions Can Learn From It

Fraud prevention that doesn’t annoy your members is no longer a nice-to-have, and the 2025 numbers from Alkami and BioCatch show why.

Alkami Technology, Inc. has announced that customers using BioCatch through the Alkami Digital Banking Platform prevented more than $263 million in fraud during 2025. BioCatch supplied the data. Alkami released it during its Cybersecurity Awareness Month.

How behavioral fraud detection works

Criminals have plenty of ways into an online banking account. Some phish for credentials. Others talk account holders into handing over sensitive information themselves. BioCatch Account Takeover Protection works from a different angle: it watches how a session unfolds rather than just who logs in.

In real time, it analyzes behavioral, device, and session signals to build a baseline of what legitimate activity looks like. Then it flags departures from that baseline, such as odd navigation, unusual interaction patterns, or strange transaction behavior. Any of those can point to a compromised account or a takeover in progress.

Every digital banking session gets a risk score. Each institution decides its own thresholds based on how much fraud risk it’s willing to tolerate, so the response fits its security strategy.

“BioCatch gives our customers another way to recognize suspicious activity during a digital banking session without introducing friction for customers or members,” said Brad Cranford, director, product management at Alkami. “The 2025 results show how behavioral and session signals are helping financial institutions detect account takeover risk earlier, giving them an opportunity to intervene before suspicious activity becomes a financial loss and helping protect the account holder relationship in the process.”

Jay Whoriskey, vice president of global partners and alliances at BioCatch, framed it around timing. “Effective fraud prevention ultimately comes down to recognizing risk early enough to do something about it,” he said. “Together, BioCatch and Alkami give banks and credit unions continuous visibility into user intent throughout every millisecond of every digital banking transaction, enabling those financial institutions to recognize account takeover in time to stop it. Preventing more than $263 million in fraud in a single year serves as a powerful demonstration of what behavioral intelligence can do at scale.”

Results from the field

Two customers offer a closer look, and the credit union example is worth a careful read.

• Gate City Bank: Using BioCatch through Alkami’s integrated partner ecosystem, the bank reported a 97% account takeover capture rate and $650K in deterred fraud loss over the last six months.
• Raiz Federal Credit Union: The team built a layered security strategy and prevented more than $286K in fraud in its first year. That figure reflects BioCatch working alongside the credit union’s other security solutions.

Raiz’s story is a reminder that behavioral analytics works best as one layer among several, not a lone defender. For credit unions, where member trust is the whole business, catching a takeover without adding friction to every login is a real advantage.

BioCatch is available through the Alkami Alliance partner ecosystem and connects with the Alkami Digital Banking Platform.

Stopping fraud mid-session, before money moves, is where the best defenses are heading.
