The award-winning TeleWall® Telecom Firewall helps you secure your voice network against abusive or unauthorized access and usage through patent pending call type detection technology.

The TeleWall Firewall detects, logs, and controls all inbound and outbound telecom network activity based on user defined, automated security policies. It protects enterprise data networks, phone systems and other critical infrastructure from back-door modem access and other external attacks through the Public Switched Telephone Network (PSTN). And its granular usage policies can prevent abusive or malicious use of your enterprise telecom resources by internal and external callers, and reduce the costs of voice network infrastructure, service and management.

The TeleWall Telecom Firewall works side-by-side with your data firewall to secure your organization's connections to the Internet and PSTN, helping complete your secure corporate electronic perimeter.
