Leadership instituted a policy to implement TSG phones in a phased approach across the Agency as a Technical Surveillance Countermeasure (TSCM). CIS Secure engaged with multiple, geographically dispersed Agency technical teams to understand the breadth and scope of the areas that needed to be addressed. The agency had – and continues to have – multiple phone systems spread across the country ranging from analog handsets to numerous VoIP platforms. CIS Secure’s broad and growing portfolio of TSG-approved instruments was able to meet the needs of the disparate phone networks across the country. In addition, the CIS Secure team worked with Agency leadership to understand emerging VoIP requirements and developed new solutions to help meet these needs.
