Investigation Services

Investigation Services

Millions of people are employed by the U.S. Government, performing vital missions in support of our country’s national security and interests. CACI is the company customers trust to deliver quality, timely, and thorough investigation services for national security missions. Our investigators serve as the first line of defense to protect national security.


CACI is an industry leader in delivering quality, timely investigations for the Department of Defense, Intelligence Community, and U.S. Government customers. We leverage business processes that have been refined by more than 17 years of investigative services experience with the U.S. Government, and we deliver innovative solutions that continuously improve our processes.

What makes CACI different is our business model – all investigative services are performed by CACI employees and are never outsourced to independent contractors. This differentiator ensures dependability, industry-leading training, shared lessons learned, and the delivery of higher quality and more timely services. We have more than 1,000 investigators on staff for scalable support nationwide, including in U.S. territories.
