Employee-Owned, Mission-Driven

Founded in 1963, Data Systems Analysts, Inc. (DSA) has been providing Defense and Federal Government customers’ business-driven Information Technology and consulting solutions and services for more than 50 years. DSA's people excel in helping our customers achieve sensitive, mission-critical business goals and objectives. DSA is a 100 percent employee-owned company: every employee has a stake in the success of our company and our customers.

Since its inception, DSA has played an important role in supporting the U.S. Warfighter. In one of its first major programs in the early 1960s, DSA partnered with the U.S. Department of Defense (DoD) to provide a secure and reliable messaging system for America's fighting forces and our allies. DSA engineers developed the world's first packet switch in the 1960s and helped pioneer the use of electronic messages for the DoD. These innovative solutions have been critical in supporting U.S. fighting forces to command, control, and communicate on battlefields from Vietnam to the most recent conflicts in Iraq and Afghanistan.

Building on our experience spanning five decades, DSA has deep expertise and comprehensive understanding of the operational, security, collaboration, and identity management challenges our customers must address. We provide secure information management solutions that encompass Program Management, Knowledge Management, Business Process Engineering, and Security. Our services include Cyber Security, SharePoint Solutions, Software Development, Data Analytics, and Systems Engineering. DSA’s headquarters is located in Trevose, PA. Additional DSA office locations are in Aberdeen MD, Colorado Springs CO, Charlottesville, Fairfax and McLean VA, Fort Detrick MD, Tinton Falls, NJ and O'Fallon IL (Scott AFB).

DSA's success is driven by our Guiding Principles, the foundation for our winning team since we opened our doors in 1963. They define who we have been and who we are today. We build on our past achievements, continually seeking new ways to improve performance, provide our customers the most innovative and effective solutions to their requirements, and deliver excellence in all of our endeavors.
