TNS Launches Voice Security to Protect Against Fraud Threats

Transaction Network Services (TNS), a leading telecom player in call authentication and robocall mitigation, has introduced TNS Enterprise Voice Security, a new suite of applications designed to protect enterprises from modern fraud tactics targeting contact centers. The solution defends against threats such as vishing, AI-powered voice cloning, customer impersonation, and IVR mining.

Today, cybercriminals increasingly attack the contact centers of mid-to-large enterprises with highly convincing vishing scams and Telephony Denial of Service (TDoS) attacks. These intrusions exploit vulnerabilities in Interactive Voice Response (IVR) systems and voice networks. With nearly 10% of inbound voice traffic deemed threatening, enterprises face growing risks that now demand urgent attention from CISOs, contact center leaders, and the C-Suite.

“While IT and security leaders for ‘high-touch’ industry enterprises and CCaaS providers have made significant investments to protect data networks and email systems, voice channels, specifically inbound traffic, have historically been overlooked in terms of cybersecurity investment,” said Seth Walton, General Manager, TNS Communications Market. “TNS Enterprise Voice Security secures inbound call traffic to facilitate 360-degree call protection, ensuring enterprises safeguard their customers from fraud and identity theft.”

The TNS Enterprise Voice Security suite combines TNS Voice Firewall and TNS Inbound Authentication, backed by TNS’ managed services expertise. Built on a zero-trust framework that meets compliance and cybersecurity standards, it empowers enterprises and CCaaS providers with four major capabilities:

1. 360-Degree Call Protection
   The solution safeguards inbound traffic with TNS’ advanced spam detection algorithms. It blocks spam and spoofed calls, enforces zero-trust policies, generates reputation scores, and even detects deepfake voices without requiring cumbersome voice signature authentication.

2. IVR System Protection
   TNS Voice Firewall instantly blocks robocalls, TDoS attacks, impersonation scams, and AI bot calls. By filtering these threats, it protects contact centers and enterprise lines from disruption, fraud, and abuse.

3. Enhanced Agent Efficiency
   Fraud attempts often waste valuable agent time and frustrate customers. TNS Inbound Authentication shifts from traditional knowledge-based authentication to passive authentication through its API. This reduces call queue congestion, cuts operational costs, and improves the customer experience.

4. Enterprise-Wide Call Monitoring
   The solution provides proactive, real-time monitoring of inbound threats. TNS’ support team partners with enterprises to manage daily inbound security operations, ensuring malicious actors are blocked before they can disrupt business processes.

Built for scalability, TNS Enterprise Voice Security equips enterprises to protect their contact centers on a global level. By addressing vishing, AI voice cloning, IVR mining, and impersonation fraud, it helps enterprises close a long-overlooked cybersecurity gap and strengthens the defense of their inbound voice channels.
