COMPREHENSIVE VOICE SECURITY FOR THE ENTERPRISE
Defend the Human Attack Surface
Voice Security for Enterprise Communications
Defend employees, executives, and critical business operations from voice-based threats before attackers gain access to people, systems, or sensitive information.

Superior Voice Security
for the Enterprise
Voice Traffic Filter helps organizations stop high-volume attacks, social engineering campaigns, and AI-driven threats before they reach employees.
By adding security controls directly to the voice network, enterprises gain greater visibility, stronger protection, and reduced exposure to operational, financial, and cybersecurity risks.
Security Insights
Protecting the Voice Channel is Critical for your entire Enterprise

Voice Is an Open Door
Unlike email and network traffic, Voice lacks meaningful security controls, leaving the door wide open for threat actors.

Social Engineering Drives Breaches
Attackers increasingly use voice to manipulate employees and gain access to systems, credentials, and sensitive information.

Initial Access Starts with a Call
Voice-based attacks are frequently used to establish trust before launching broader cyberattacks.

Business Disruption Is Expensive
Spam storms, spoofing, and call flooding can disrupt critical operations and communications.

AI Has Raised the Stakes
AI-generated impersonation and automated attack campaigns are making traditional awareness training inadequate.
Trending Voice Threats
High Volume Attacks
Unwanted Voice Traffic Is Overwhelming the Enterprise
High-volume nuisance calls, robocalls, spoofing, and spam storms are no longer just distractions. They degrade operations, overwhelm contact centers, distort KPIs, and create the conditions for more dangerous attacks to succeed.
Initial Access Attacks
Voice Has Become the Primary Entry Point for Cyberattacks
Vishing and social engineering attacks are now proven initial access vectors behind major breaches. Attackers exploit the lack of technical controls in voice to connect directly with employees and manipulate them in real time.
AI-Based Attacks
AI Has Weaponized Voice Into a Scalable, High-Impact Threat
Deepfake voice cloning, AI-generated impersonation, and automated attack campaigns have dramatically increased the speed, scale, and success rate of voice-based attacks, rendering traditional defenses and training insufficient.
The Value of Multi-Layered Security
Protect Employees, Strengthen Cyber Defense
A multi-layered voice security strategy protects employees from unwanted and malicious callers, preventing attackers from reaching the human endpoint.
The result is reduced cyber risk, stronger security posture, improved workforce productivity, and a lower likelihood of fraud, account compromise, and data breaches.
