The Growing Threat of Voice-Based Fraud

The rise in contact centre fraud isn’t simply a matter of increased call volume; it’s a shift in the type of fraud. Traditional methods are being superseded by increasingly sophisticated techniques, most notably the emergence of deepfake technology. Pindrop’s technology leverages a combination of device recognition, proprietary Phoneprinting® technology, behavioural analysis, and advanced deepfake detection to identify and neutralize these threats.

Currently, nearly one in every 106 calls exhibits signs of “non-live” activity, indicating the use of synthetic voices or AI-driven impersonation. This represents a nearly seven-fold increase in deepfake activity over the past year. By embedding Pindrop’s detection capabilities directly into BT’s network infrastructure, UK enterprises gain a critical defensive layer against these evolving attacks.

“With 1 in 106 calls already showing signs of deepfake activity, threats like synthetic speech and agentic AI are rewriting the fraud playbook,” stated Bucky Wallace, Chief Revenue Officer at Pindrop. “Together with BT, we’re giving UK enterprises a modern defence—advanced voice intelligence that continuously adapts, spots risk earlier, and future-proofs contact centres for both security and customer experience.”

Pindrop’s ability to integrate seamlessly with leading Contact Centre as a Service (CCaaS) platforms is a key advantage. This flexibility allows for rapid deployment and simplified maintenance across both legacy and cloud-based systems, delivering a measurable return on investment through fraud prevention, streamlined authentication, and reduced agent handling times – all while preserving a positive customer experience.

The new capabilities are immediately available to BT’s UK enterprise customers, demonstrating a shared commitment to innovation and operational excellence. As AI-powered attacks become more sophisticated, this partnership is designed to protect the UK’s most trusted brands and institutions, ensuring the integrity and reliability of voice communications.

Did You Know? Phoneprinting® technology creates a unique identifier for each calling device, even if the caller attempts to mask their number, providing an additional layer of security.

Frequently Asked Questions About Voice Fraud Protection

1. What is voice biometric authentication and how does it prevent fraud? Voice biometric authentication analyzes unique characteristics of a person’s voice to verify their identity, making it significantly harder for fraudsters to impersonate legitimate customers.
2. How effective is Pindrop’s Phoneprinting® technology in identifying fraudulent calls? Phoneprinting® technology creates a unique identifier for each calling device, allowing Pindrop to detect anomalies and identify potentially fraudulent calls even if the caller attempts to mask their number.
3. What are deepfakes and how are they used in contact centre fraud? Deepfakes are synthetic media created using artificial intelligence, often used to mimic a person’s voice or appearance. In contact centre fraud, they can be used to impersonate customers or employees.
4. Can Pindrop’s technology be integrated with existing contact centre infrastructure? Yes, Pindrop offers native integration with leading CCaaS platforms, enabling rapid deployment and simplified maintenance across both legacy and cloud-based systems.
5. What is the potential ROI of implementing Pindrop’s voice security solutions? Businesses can expect a measurable ROI through improved fraud prevention, streamlined customer authentication, reduced agent handling time, and enhanced customer trust.
6. How does the BT-Pindrop partnership benefit UK businesses specifically? The partnership provides UK businesses with access to cutting-edge voice security solutions tailored to the evolving threat landscape, protecting them from financial losses and reputational damage.
