Tucson Federal Credit Union Enhances Member Security with IllumaSHIELD™

Tucson Federal Credit Union (TFCU) has partnered with Illuma, the leader in voice authentication and caller fraud prevention technology, to deploy IllumaSHIELD™ across its contact centers—bringing faster, more secure member verification through voice biometrics.

The IllumaSHIELD™ solution passively authenticates members in real time during live calls, replacing traditional security questions with an effortless voiceprint process. This allows TFCU to shorten call times, reduce fraud risk, and deliver a more seamless member experience.

“Our members deserve both convenience and strong protection,” said Krystal Adams, Chief Operating Officer at TFCU. “With IllumaSHIELD™, we’re able to verify callers securely—while providing the friendly, high-touch service our community expects.”

TFCU’s adoption of voice authentication is part of a larger innovation strategy that includes recent branch remodels and new locations in Oro Valley and Vail. As the credit union expands its footprint, it continues to invest in both digital and in-person service enhancements that prioritize member needs.

“We’re proud to support forward-thinking credit unions like TFCU,” said Milind Borkar, CEO of Illuma. “IllumaSHIELD™ allows organizations to fight fraud without creating friction—and that’s exactly what modern contact centers need.”

Key benefits of the implementation include:

• Passive, real-time authentication—no PINs, passwords, or challenge questions
• Reduced call times and improved agent efficiency
• Stronger fraud prevention with less member effort

IllumaSHIELD™ integrates seamlessly with contact center platforms, making implementation straightforward and scalable for institutions like TFCU.
