Due Diligence & Security Clearance Background Investigations
In today’s evolving threat landscape, organizations operating in national security, critical infrastructure, and sensitive government programs cannot afford uncertainty when selecting personnel. SENTRYSIX provides comprehensive Due Diligence and Employment Background Investigation services engineered to meet the rigorous standards required for security clearances and high-trust positions. Our investigative process goes far beyond a standard background check—delivering a 360-degree assessment of an individual’s integrity, reliability, and suitability for sensitive roles.
Our team leverages advanced intelligence methodologies, open-source intelligence (OSINT), database research, and discreet field inquiries to identify potential vulnerabilities before they become operational risks. From financial responsibility and criminal history to social media behavior, affiliations, and lifestyle indicators, we uncover the details that matter most when assessing trustworthiness and insider-threat potential. Whether your organization requires baseline vetting or enhanced due diligence for executive, contractor, or cleared personnel, SENTRYSIX provides the clarity and confidence needed to make informed decisions.
SENTRYSIX’s investigative professionals include former law enforcement, intelligence, and military personnel with extensive experience navigating federal security-clearance standards, including those outlined by the Department of Defense, DHS, and national-security agencies. We ensure each investigation aligns with federal adjudicative guidelines and industry best practices, giving our clients an unmatched level of accuracy, discretion, and accountability. Our mission is simple: protect your organization by ensuring only the most qualified, credible, and trustworthy individuals gain access to your sensitive systems, facilities, and information.
With SENTRYSIX, you gain more than a report—you gain a strategic security partner dedicated to mitigating personnel risks and strengthening your overall security posture.
