With a long history of providing a broad range of security-related services, ADCL's personnel investigation capabilities are unparalleled in the industry.

For pre-employment and ongoing security verification, our leading-edge ADCL hosted software application gives you customized information on applicants for employment or security clearances based on our direct online access to comprehensive background information from reliable sources. Our system can meet your Human Resources (HR) and personnel security requirements.

ADCL, of course, is ready to help government agencies beyond routine screening and standard background checking. When our clients need more in-depth background investigation work, we have access to an established team of over 1,200 trained and experienced Associate Investigators (AI). Strategically located throughout the nation, these contract investigators, most of whom are former FBI, CIA and Secret Service, hold Secret clearances and agency credentials; they are available to us whenever your agency needs specialized professionals for customized background investigations or adjudication of investigations for personnel security clearances. Furthermore, as you will see on our SERVICES page, we have extensive experience providing armed and unarmed security guard and security escort services to government facilities and commercial firms.

No private or governmental organization has more demanding criteria for applicant security clearances than the United States Department of Defense (DoD), especially in a post 9-11 world. And since 1997, two major DoD intelligence agencies have contracted extensively with ADCL to meet these needs; in fact, we currently provide all or most of their employee background checking / security clearance investigations.

Whether you are a private company or a federal, state or local government agency, you need a support services contractor with which you can build a productive and lasting relationship, one that not only meets your requirements today, but is ready to meet whatever needs you might have in the future. And no other company is better prepared to support your facility and personnel risk assessment and mitigation needs than ADCL.
