Innovative technology built on a legacy of delivering high-performance mission-critical IT environments.
Since its incorporation, SDI has been entrusted with delivering advanced security and IT systems throughout the United States. SDI’s portfolio of clients includes airports, seaports, mass transits, utilities, and government agencies. The firm has built an expertise in addressing the higher technical and security requirements of these critical, high-value environments.
Over Two Decades of Security and IT Expertise
For more than 25 years, SDI has delivered mission-critical systems and technology services to some of our nation’s most complex and public-facing organizations and government entities.
In 1989, Environmental Systems Design, Inc. (ESD), a premier engineering firm, developed an in-house support staff to design and manage information technology solutions for its engineering disciplines. In subsequent years, the information services division was sought after to provide stand-alone technology services to local governments, utility clients and businesses in the real estate, health care, and finance industries. On November 22, 1996, the information services division emerged from the parent company as SDI (System Development.Integration, LLC) with a mission focused exclusively on providing superior information technology solutions and advisory services.
As a systems integrator focusing on such complex, large-scale operations, SDI identified a heightened need for security technology professional services. To best serve this demand, SDI strategically acquired a Charleston-based security integrator in 2013 – bringing similar past performance, security industry expertise, and commitment to client success as SDI. Today, SDI is privately held and was renamed SDI Presence LLC in June 2016.
