An innovative technology company with an unparalleled commitment to being present for our clients.
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 20 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, healthcare, 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.
Today, SDI is privately held and in 2016 was renamed SDI Presence LLC to reflect its commitment to being present for its clients, team, and community.
