Suncoast Credit Union Accelerates Member Growth and Controls Fraud Risk with Alloy

NEW YORK, May 18, 2026 /PRNewswire/ -- Suncoast Credit Union, Florida's largest credit union and one of the nation's leading financial cooperatives, has partnered with Alloy to help accelerate the financial institution's growth by helping it manage fraud risks across the organization.

The credit union is planning to nearly double in size to 2.5 million members by 2030, while continuing its member-first, mission-driven focus. To do that, the team needed a partner to help enable a seamless member experience, onboard more legitimate members, and provide access to a wider range of financial products, while mitigating risks. Suncoast chose Alloy as its strategic platform to power identity, fraud controls, and data orchestration across onboarding and ongoing member account activity.

"Alloy helps us say 'yes' to growth without compromising our member-first culture," said Eva Coffee, Manager of Digital Strategy at Suncoast Credit Union. "It gives us a centralized place to manage identity and fraud decisions across onboarding and the entire member lifecycle, so we can review ongoing account activity with more confidence, and intervene only when there's real risk. That way, we reduce friction for legitimate members."

Prior to partnering with Alloy, Suncoast saw fraud losses rising nearly 30% year-over-year. After deploying Alloy at onboarding and expanding into login monitoring and cross-channel fraud controls, the credit union reduced fraud losses by over 35% from 2023 to 2024.

Working with Alloy, the Suncoast team can easily use adaptive authentication to put potentially risky users through additional layers of step-up verification, keeping bad actors out of the platform while still preserving a seamless experience for genuine members, including "snowbirds" whose locations change seasonally.

In 2024 alone, Suncoast monitored 269 million digital logins through Alloy's platform, generating 11,990 investigations. Alloy's centralized decision engine enables Suncoast to continuously assess member risk, apply step-up verification when necessary, and automatically mitigate threats across digital, mobile, and in-branch channels.

"Alloy has delivered exceptional member growth results for Suncoast while delivering material fraud reduction," said Parilee Wang, Chief Product Officer and Chief Operating Officer at Alloy. "By using Alloy to centralize identity management throughout the customer lifecycle, Suncoast has built a scalable foundation that allows it to adapt to emerging threats, expand product offerings, and deliver dynamic, low-friction member experiences."
