How a Credit Union Scaled Digital Banking While Cutting Fraud and Friction

Background

After a major transformation initiative, the credit union set out to deliver digital banking with “fintech speed” while maintaining the trust and member-first standards people expect from a member-owned institution.

But as digital adoption accelerated, so did fraud pressure—and the team faced an all-too-familiar tradeoff: tightening controls often meant adding friction, increasing OTP (One-time Password) challenges, and creating more work for already-stretched teams. They needed a way to embed real-time fraud decisioning into the journeys that matter most—onboarding, login and profile changes, and money movement—so they could stop emerging attacks without turning everyday banking into a high-friction experience.

Challenge

The previous legacy system was built for a different era—more reactive, alert-driven, and slower to adapt. As fraudsters targeted critical digital touchpoints, the organization felt pressure from both sides: executives needed confidence that risk was under control, and members expected a seamless experience that didn’t challenge them at every turn.

Meanwhile, the fraud team was absorbing the operational impact. High volumes of reviews made it difficult to separate meaningful threats from noise, and making changes fast enough to counter new attack patterns was a constant struggle. The goal wasn’t just “more security.” It was smarter security: the right intervention at the right moment, without slowing down the digital roadmap.

• Reactive, slower fraud workflows that struggled to keep pace with new threats.
• High friction for legitimate members, with OTP challenges appearing in nearly all sessions.
• Operational overload, with ~3,000 manual reviews per day.
• Coverage gaps across key digital journeys: onboarding, login/profile changes, and money movement.
• Limited self-service control, creating dependence on vendor tickets or IT bottlenecks when strategies needed to change quickly.

Solutions

The intent was simple: make risk decisions where they matter, in the moment, with low latency and consistent member experience across web and mobile.

With dedicated scorecards for each journey, the fraud team could tune thresholds and rebalance protection versus friction themselves. That shift—toward self-service control—became essential for moving quickly when threats changed. And with device, network, and velocity intelligence feeding consolidated risk scoring, they could make more precise decisions without relying on broad, one-size-fits-all step-up authentication.

• Embedded, real-time fraud decisioning within digital journeys through a digital banking platform partner.
• End-to-end member lifecycle coverage.
• Onboarding/account opening risk assessment to detect synthetic identities and organized activity before accounts were funded.
• Real-time monitoring for login and sensitive profile changes to help stop account takeover (ATO) and risky updates across channels.
• Money movement controls that evaluate risk before adding recipients or releasing funds.
• Device, network, and velocity intelligence feeding consolidated risk scoring.
• Scorecard-driven, self-service tuning so the fraud team could adjust strategies without coding or vendor tickets.

Results

Once risk-based decisioning was embedded across the most targeted digital journeys, the impact became visible quickly—not only in fraud outcomes, but in the day-to-day experience of members and analysts alike.

Instead of defaulting to OTP for nearly every session, the credit union shifted to applying step-up only when risk signals justified it. And instead of sorting through thousands of cases per day, the fraud team could focus their time where it mattered most.
