Heksagon Wins Platinum Award for Most Innovative Voice Fraud Detection Solution

This recognition honors Heksagon's Voice Firewall (VFW) solution, which currently protects over 600 million subscribers across 16 countries, processing more than 2 billion voice calls daily and blocking over 9 million fraudulent calls per month. 

"Juniper Research has chosen Heksagon as our platinum winner for Most Innovative Voice Fraud Detection Solution owing to substantial innovation in threat mitigation and multi-layered intelligence," said Sam Barker, VP of Telecoms Market Research and Head Judge, Telco Innovation Awards, at Juniper Research. "The solution integrates LLM-based speech recognition and digital voice signatures to combat the rising threat of AI-based voice scams. Given how quickly fraud evolves and the potential impact that AI-based voice scams can cause, a solution such as Heksagon's Voice Firewall positions vendors well to tackle new forms of fraud effectively."

Since deploying one of the world's first Real-Time Voice Firewalls in 2012, Heksagon has consistently led the industry in voice fraud prevention innovation. The company was the first to develop a Call Validation Solution outside North America in 2018 and the first vendor to introduce Regional Call Validation to the GSMA VINES working group in 2020.

"This award validates our commitment to staying ahead of evolving fraud threats and protecting both operators and their subscribers," said Andraz Oblak, Co-Founder of Heksagon. "As voice fraud becomes increasingly sophisticated, especially with AI-generated scams, we’re proud that our continuous innovation provides telecom operators with the most comprehensive defense available."

What sets Heksagon's Voice Firewall apart is its comprehensive approach to voice security. Unlike conventional solutions that focus solely on detection, our VFW provides users with:

End-to-end protection against all major voice fraud types, including CLI spoofing, vishing, SIMBOX fraud, robocalls, interconnect bypass, and IRSF/Wangiri scams

• Real-time call validation that prevents fraud before it happens, not just after detection
• AI-powered threat intelligence with adaptive machine learning that evolves to combat emerging fraud patterns
• Revenue generation capabilities through Branded Calling, Call Validation, and Flash Call Monetization services that operators can use to tap into new revenue streams
• Industry-leading accuracy with a 0.01% false positive rate, ensuring legitimate calls flow uninterrupted

The platform's upcoming release will introduce digital voice signatures and LLM-based speech recognition to combat the rising threat of AI-generated fraudulent calls and AI-cloned voice scams, further future-proofing operator networks against next-generation threats.

Deployed both under the Heksagon brand and through white-label partnerships with regional telecom providers, the Voice Firewall solution enables operators of all sizes to deliver advanced voice protection capabilities. The solution's seamless integration with both legacy and next-generation network elements (TDM, IP, VoLTE, VoWiFi, 5G) ensures operators can protect their networks today while preparing for tomorrow's technologies.

Beyond telecom operators, Heksagon also supports 15 major commercial banks globally, protecting 75 million banking clients from vishing, impersonation, and bank scams through real-time CLI spoofing prevention and fraud event monitoring.

Heksagon maintains active membership and contributes to multiple industry working groups, including GSMA Fraud and Security Groups (FASG), CFCA, and One Consortium (WG1 and WG3). The company's solutions are fully compliant with international telecom standards (ITU-T, 3GPP, IETF) and certified under ISO 9001 and ISO 27001, with full GDPR compliance ensuring data privacy and security.

"We're not just building fraud prevention tools, we're actively shaping industry standards and best practices," added Andraz Oblak. "This collaborative approach ensures our solutions address real-world challenges facing operators and their subscribers."
