A Trusted Partner, Leader and Innovator in Background Investigations

We have been a trusted partner for Federal government, commercial and industry support customers since 1990. Our nationwide network of investigators performs a variety of investigative activities for customers including the Department of Defense (DoD), multiple agencies within the Department of Homeland Security (DHS), the Intelligence Community, civilian government agencies, and commercial firms that encompass broad business sectors such as aerospace manufacturing, banking, insurance, finance, information technology, education and telecommunications.

Our Investigative Services Group (ISG) specializes and performs Background Investigations (BI) services within the contiguous United States, Alaska, Hawaii, and all U.S. territories/possessions, as well as in customer specified overseas locations. We are committed to integrity, quality and service in support of each customer’s unique mission. Our highly trained, dedicated management team can rapidly deploy staff with unparalleled customer service, facilitating operations stateside or abroad.

Constellis is the most diversified provider of investigations to the government and the only investigative service provider in our industry currently conducting overseas investigations. We employ the latest advancements in information-gathering technologies to ensure a complete analysis of each individual seeking security clearance, from social media checks to electronic fingerprinting. We also designed the prototype for electronic receipt and delivery of federal government investigations. This is all achieved through our proprietary case management system that was designed and maintained in-house, specifically as a tool to oversee every aspect of an investigation in real-time.
