SDI Acquires Another Systems Integrator: X7

System Development.Integration, LLC – better known as SDI, a systems integrator targeting mission-critical technology and infrastructure – has acquired X7.

X7 is also a systems integrator, and was described in media reports as a “rival” to SDI. X7 offers security management systems.

Both firms provide managed services for clients, and they run organizations’ complex networks, news reports add.

Financial terms of the deal were not disclosed by the companies.

The deal represents the second acquisition for SDI in two months. SDI recently added i-sys, Corp, a systems integrator providing environmental and fire safety solutions, as well as security offerings.

SDI says it is now a $70 million systems integrator focusing on “complex technical requirements, risk mitigation strategies, and advisory services required by critical infrastructure-intensive environments.”

“Every organization’s critical infrastructure presents unique threat measures and operational requirements, demanding a tailored approach to building its security technology platform. SDI brings deep IT expertise throughout the lifecycle of large-scale security technology programs to gain functionality, cost, and productivity advantages for our clients,” SDI CEO David A. Gupta said in a statement.  “X7’s system design-build competence, advanced industry certifications, and proven management team complement our subject matter experts, further strengthening us as a single-source provider of integrated security platforms and managed services for critical infrastructure and campus environments.”

X7 was started in 1999 as the Orion Systems Group. Among its users are Washington, D.C.’s citywide Electronic Security System (ESS) program, the Metropolitan Police Department, Virginia Tech University and Morgan State University.

In commenting on the deal, David Taylor, X7’s CEO said, “The increasing complexity of technology, information systems, and regulatory compliance – particularly in the critical infrastructure marketplace – demands the elite expertise, engineering, and operational support provided by SDI and X7.”

The Chicago Tribune says SDI has some 130 employees in Chicago and it will increase to a staff of 250 with the two recent deals.

Last year, SDI saw $40 million in revenue. Also, 2013 revenues are predicted to be $70 million.
