Illuma has joined the Eltropy partner ecosystem, giving Eltropy customers access to Illuma's voice security tools.
The partnership centres on IllumaSHIELD, a platform for voice authentication and fraud prevention in financial services. Eltropy customers, including community financial institutions, will be able to use the system during account holder interactions across voice channels.
Both companies are addressing a growing problem as fraudsters use artificial intelligence, deepfake audio and social engineering to defeat older verification methods. Knowledge-based authentication and one-time passcodes have become less reliable on their own, particularly in contact centres and other customer service settings.
Illuma says its platform combines passive voice authentication, fraud detection, adaptive multi-factor authentication, deepfake detection and shared intelligence in a single system. The technology can be used in both live agent calls and self-service voice interactions.
Fraud pressure
Financial institutions are under pressure to tighten controls around customer communications without making routine account access more cumbersome. Voice channels remain a persistent risk because they rely on spoken interactions that can be manipulated through impersonation, stolen personal data or synthetic media.
The integration reflects a wider trend among financial technology suppliers to embed identity checks more directly into service workflows. Rather than requiring customers to stop and complete separate verification steps, providers are increasingly trying to authenticate users during the conversation itself.
Dr Milind Borkar, Founder and Chief Executive Officer of Illuma, said the shift is forcing institutions to rethink how they secure voice interactions.
"Voice fraud has evolved far beyond traditional authentication challenges, forcing financial institutions to rethink how they secure every conversation," said Dr Milind Borkar, Founder and Chief Executive Officer, Illuma.
"IllumaSHIELD delivers a modern Voice Security approach that combines passive voice authentication, deepfake detection, adaptive MFA, and real-time fraud intelligence into a single platform. Financial institutions routinely implement IllumaSHIELD in days, reduce verification times by up to 95%, lower average handle time by more than 80 seconds per call, and strengthen protection against increasingly sophisticated AI-driven attacks-all while delivering a faster, more seamless account holder experience," said Borkar.
The partnership adds to Illuma's broader set of technology integrations, enabling financial institutions to deploy voice security products without major changes to their current contact centre or engagement systems. For banks and credit unions, that matters because replacing core communications infrastructure can be costly and disruptive.
Platform reach
Eltropy provides communications software to community financial institutions, bringing together text, chat, video, and voice interactions on a single platform. By adding Illuma to its partner network, Eltropy is extending its identity verification and fraud-control capabilities at a time when customer service channels are becoming increasingly automated.
Abhishek Tiwari, Chief Product Officer of Eltropy, said the company views authentication as a core part of digital service infrastructure.
"Illuma shares our belief that trusted authentication is foundational infrastructure, not a checkbox," said Abhishek Tiwari, Chief Product Officer, Eltropy.
"Financial institutions shouldn't have to put their members through hoops to get secure, fast service, and with Illuma embedded in the Eltropy platform, they won't have to. Financial institutions can verify identity in seconds without interrupting the conversation. That's the kind of experience that builds lasting trust, whether the interaction is human-led or Agentic AI-powered," said Tiwari.
The companies are framing the tie-up around the idea that security and speed no longer need to compete. In customer service operations, shaving time from each call can ease staffing pressure, while stronger authentication may help institutions reduce account takeover attempts and impersonation fraud.
Illuma describes its core offering as layered voice security, including passive voice authentication during natural conversation, real-time fraud and social engineering detection, deepfake threat detection, risk-based multi-factor authentication and protection across both agent-assisted and automated channels.
The focus on voice also reflects sector-wide concern about the spread of synthetic audio tools. As generative AI systems make it easier to mimic speech patterns and identities, financial institutions face a growing need to distinguish legitimate customers from impostors without creating longer, more frustrating service journeys.
For Eltropy, adding Illuma gives its platform another specialised security function as community lenders and credit unions look for tools that integrate with existing operations. For Illuma, the agreement broadens distribution through a provider already used for customer communications across a range of financial institutions.
The integration is intended to support secure authentication across both human-led and automated voice interactions.
