Trust Every Call: Deepfake Detection & Voice Authentication That Scales

How important is it to know that every call you take can be trusted?

If you’re leading cybersecurity, risk, or operations in today’s enterprise, you already know how fast the landscape is changing.
The voice channel, once trusted and overlooked, has become one of the most vulnerable entry points into every organization.

Contact centers and help desks sit right on the front line. They’re the “human gateways” to sensitive systems and customer data, and now they’re being targeted by AI-driven deepfake and social-engineering attacks that are nearly impossible to detect with traditional tools.

And with Nuance and other legacy vendors exiting the voice authentication market, enterprises and governments are facing a critical question:
How do we secure the voice channel, the most exploited, least defended, and fastest-growing attack vector in cybersecurity?

That question, and what organizations can do about it, is at the heart of an upcoming discussion hosted by ValidSoft and Reality Defender, exploring how enterprises are responding to the new reality of AI-generated voice threats.

The Growing Threat to Voice Security

Deepfake voice fraud is no longer a future risk. It’s here, it’s accelerating, and it’s hitting where organizations are most exposed, their people.

Attackers are cloning executives’ voices to approve fraudulent transactions. They’re impersonating employees to gain access to critical systems. They’re weaponizing AI to exploit human trust.

The results are devastating brand damage, regulatory exposure, and multimillion-pound financial losses. Recent cases at Jaguar Land Rover and Marks & Spencer show that even the most sophisticated enterprises are not immune.

Legacy authentication systems, passwords, tokens, even older voice biometrics, simply weren’t designed to detect synthetic or manipulated audio. As a result, the voice channel has become the blind spot in enterprise security.

Migration: A Risk and an Opportunity

For organizations that previously relied on Nuance (which no longer offers solutions in this space), or other legacy vendors, this market shift presents both risk and opportunity. Yes, it’s disruptive, but it’s also a moment to leap forward.

Moving away from legacy platforms gives enterprises the chance to adopt modern AI-powered voice security that can detect deepfakes, authenticate legitimate users, and deliver provable identity assurance, all in real time.

This isn’t just about replacing a vendor. It’s about rebuilding trust in every voice interaction.

The ValidSoft + Reality Defender Alliance: Redefining Trust in the AI Era

To close the widening gap in voice security left by departing legacy providers, ValidSoft and Reality Defender have formed a strategic alliance, combining two industry-leading technologies to deliver real-time protection against AI voice fraud.

The collaboration brings together ValidSoft’s patented Voice Identity Platform™, which provides real-time, passive voice biometric authentication and cryptographic voice assurance, with Reality Defender’s RSA Innovation Award-winning, API-first deepfake detection platform.

The result is a multi-layered, battle-tested defense against synthetic voice impersonation, fraud, and AI-driven manipulation, purpose-built for critical environments such as contact centers, help desks, and digital service channels.

Born from a shared mission to protect trust in digital communications, this alliance brings together decades of expertise in financial technology, cybersecurity, and AI innovation.
Together, these technologies enable enterprises and governments to achieve real-time identity assurance, deepfake detection, and cryptographic proof of authenticity across every conversation.

This partnership sets a new standard for proactive defense of voice communications, protecting every interaction, every customer, and every transaction from AI-generated threats.

Restoring Trust in Every Call 

The voice channel remains the most human way we communicate. It’s how trust is built, and, increasingly, how it can be broken.

As deepfake voice attacks escalate, securing that channel has become the #1 cybersecurity priority for modern enterprises.

The ValidSoft–Reality Defender alliance isn’t just about technology. It’s about restoring trust in human communication, giving organizations the power to know, with certainty, who they’re talking to.

To explore how enterprises are addressing this challenge, and what best practices are emerging, join the upcoming ValidSoft and Reality Defender webinar on December 2^nd to discuss, trusting every call: deepfake detection & voice authentication that scale.
