About

The National Counterintelligence and Security Center (NCSC) serves as the United States’ leading authority on counterintelligence and security, directing and supporting federal CI initiatives that safeguard the nation from foreign and adversarial threats. In addition to coordinating government efforts, NCSC engages with private‑sector partners to mitigate the risk of foreign intelligence infiltration and issues public alerts on emerging intelligence hazards. NCSC delivers a comprehensive portfolio of services—including insider threat mitigation, physical and personnel security, supply‑chain risk management, critical infrastructure protection, technical security, and counterintelligence outreach—designed to strengthen resilience across both public and private domains. By providing actionable intelligence and expert guidance, the Center empowers organizations to proactively identify, assess, and defend against complex security challenges.
