The professional services firm Vistronix, LLC, recently said it has acquired Technology Associates International Corp., an information technology (IT) support services company that provides geospatial and data visualization software applications and systems and also operates command and control centers.

Terms of the deal were not disclosed. Technology Associates, which like Vistronix is based in Northern Virginia, does about $35 million in annual sales and has more than 200 employees. Vistronix has about $45 million in annual sales and has more than 250 employees.

For Vistronix, Technology Associates’ geospatial applications were the most interesting aspect in pursuing the deal, John Hassoun, president of Vistronix, said recently. He said Vistronix is “bullish” on parts of the IT services market, particularly around geospatial applications development, test and evaluation for independent verification and validation, an area his company already specializes in, command center operations, and cyber security as a component to everything the company does.

Technology Associates’ geospatial capabilities provide applications for decision support and critical infrastructure work by building and pulling data from various sources and being able to display it in a map-like format on various mobile and computing devices, Hassoun said.

In addition to helping Vistronix expand its business in certain key areas, Hassoun said that the deal also complements the company’s strategy of building a mid-tier national security company. Hassoun said Vistronix has a broad perspective on national security, which includes federal civilian agencies and sectors and clients outside the United States, in the protection of financial integrity, natural resources, and others.

Vistronix’ clients are primarily in the federal civilian space. Technology Associates’ largest customer is the Marine Corps, followed by the Department of Health and Human Services (HHS) and the Air Force. Technology Associates supports the security operations center for HHS.

Vistronix expects to be able to take its existing capabilities, particularly in the area of IV&V, and broaden it with its new customers, but also leverage Technology Associates’ capabilities and provide them to its existing as well as future customers, Hassoun said.

Technology Associates also has capabilities in enterprise IT and cyber security, Hassoun said.

SunTrust Bank provided financing to Vistronix on the deal and also served as Technology Associates’ financial adviser.
