Industrial Defender Acquires Teltone

The deal is said to fill out the company’s suite of cyber security offerings for the electric power industry.

Industrial Defender Inc. (, a Foxborough, Mass.-based industrial cyber security services and consulting firm, announced on June 24 that it has acquired Teltone Corp. (, Bothell, Wash., a provider of secure communications for electric power substations. No details of the transaction were provided.

Teltone’s Gauntlet secure substation communications product has become a trusted solution for driving compliance with the federal Critical Infrastructure Protection (CIP) reliability standards within dial-up environments, while providing a transparent path to Internet protocol (IP) connectivity, Industrial Defender said. The Gauntlet Gateway is based on Teltone's Substation Line Sharing Switch (SLSS) technology, installed in 85 percent of North American substations.

The electric power industry requires a cyber defense solution that provides support for its entire infrastructure, including Energy Management Systems (EMS), power generation assets, and transmission and distribution assets. With the convergence of enterprise and industrial networks, the industrial control and supervisory control and data acquisition (SCADA) systems that operate and manage infrastructure assets are faced with a significant increase in cyber security threats and vulnerabilities—the driving force behind the so-called NERC CIP standards, developed by the National Electric Reliability Corp. (NERC).

Industrial Defender extends its electric power “Defense-in-Depth” solution with Gauntlet technology, the company said, providing customers with infrastructure cyber security, performance and compliance solutions in a flexible and cost effective platform to meet the evolving needs of the electric power market. With the Teltone acquisition, Industrial Defender contends that it now offers the electric power industry’s most comprehensive cyber security solution for industrial control and SCADA systems.
