Entarian

Entarian is an engineering and federal technology firm that supports U.S. defense and civilian agencies with satellite mission operations, secure networks, command and control systems and cyber defense. Its work includes satellite calibration that supports weather data used by FEMA, DHS and DOD, and a cyber-secure terrestrial network for the U.S. Space Force. The firm also handles tactical radio modernization for the U.S. Army.

Most of the business is contract work for government customers rather than walk-in trade, and the firm lists its contract vehicles and case studies publicly. Entarian was known as ERT until a 2026 rebrand that followed its acquisition of Sev1Tech. It is headquartered in Greenbelt, Maryland, with 13 offices across the country and staff placed in customer offices. Interested parties can reach the team by phone or email to discuss partnering.
