Convergint Technologies, a worldwide leader in service-based systems integration, today announced the acquisition of the Charleston-based Integrated Security Systems Division (ISSD) of SDI Presence. A key trait shared between ISSD and Convergint is uncompromising customer service.

ISSD brings Convergint rich expertise across the banking, education, and state and local government markets. All 50 members of the current ISSD team will be joining Convergint, including its leadership. Many of the existing colleagues will work from the Charleston location, with the balance supporting several national accounts across the country.

“The company cultures of SDI and Convergint are closely aligned, which will provide the ISSD team with a smooth transition to many opportunities for advancement within Convergint’s growing security portfolio and services platform,” said David Gupta, CEO of SDI Presence, the former parent company of ISSD. “This transaction also serves to strategically reinforce SDI’s professional services focus on our core IT domain expertise and emerging digital solution areas for our clients.”

Convergint Technologies was founded in 2001 on a foundation of Values & Beliefs, and it has since grown to become the second largest integrator in the world. Central to Convergint’s success is the culture established by its Values & Beliefs, of which customer service is the core focus. That dedication still drives the company today and is a key attribute for the companies brought into the organization.  ISSD shares in this service commitment and marks the twelfth acquisition Convergint has completed in the last two years. 

“We are excited to have ISSD as part of the growing Convergint family. They bring to Convergint a strong service-based culture, vertical market expertise, and a thriving local business in South Carolina. We welcome all ISSD colleagues who will be joining Convergint, and are thrilled to have Todd Smith and Sean Kennedy join our leadership team,” said Dan Moceri, Executive Chairman and Co-founder of Convergint Technologies.

Imperial Capital advised SDI Presence on the sale of ISSD.
