Fort Sill Federal Credit Union Partners With Illuma To Advance Voice Security And Protect Member Interactions

Fort Sill Federal Credit Union and Illuma, the leader in AI-powered voice security for contact centers, today announced a partnership to implement IllumaSHIELD™ Voice Security—enhancing protection against rising voice-based fraud while delivering faster, seamless member experiences.

Through this partnership, Fort Sill Federal Credit Union will deploy IllumaSHIELD™ to secure contact center conversations in real time using a layered approach that combines passive voice authentication, fraud detection, collaborative intelligence, and adaptive multi-factor authentication.

As fraud tactics continue to evolve—particularly with the rise of AI-generated voices and social engineering—financial institutions must secure the voice channel without introducing friction for legitimate callers. IllumaSHIELD™ addresses this challenge by verifying members passively as they speak, eliminating the need for outdated knowledge-based authentication questions while continuously analyzing calls for signs of fraud.

“Delivering secure, seamless service is critical to how we support our members every day,” said Jayson Sims, President & CEO of Fort Sill Federal Credit Union. “By partnering with Illuma, we’re strengthening our ability to protect member accounts while improving the overall contact center experience.”

IllumaSHIELD™ provides layered voice security by combining real-time voice biometrics, fraud risk scoring, and adaptive authentication. The platform enables contact centers to reduce average handle time, improve agent efficiency, and stop fraud attempts earlier in the interaction—before losses occur.

“Credit unions are facing a new wave of voice-based fraud driven by AI and social engineering,” said Milind Borkar, PhD, Founder and CEO of Illuma. “Fort Sill Federal Credit Union is taking a proactive approach to protecting its members by securing every voice interaction. Together, we’re delivering stronger security while eliminating friction—ensuring a better experience for both members and agents.”

IllumaSHIELD™ is often implemented in days and delivers measurable results immediately, helping credit unions modernize their contact center security while maintaining a member-first approach.
