Chair of the National Security & Strategic Threat Council

Former HSI Supervisory Special Agent and Section Chief • Builder and leader of HSI’s Government Supply Chain Investigations Unit • Former Assistant Attaché, Frankfurt, Germany • Undercover counterproliferation investigator

Brian Andersen is a retired Homeland Security Investigations Supervisory Special Agent and national security investigations leader with more than 20 years of federal experience across counterproliferation, export controls, sanctions, financial crime, human rights, war crimes, and government supply chain security.

As an architect and leader within HSI’s Government Supply Chain Investigations Unit, Brian focused on building the teams, tools, and investigative frameworks needed to identify and disrupt counterfeit, substandard, non-compliant, and fraudulently sourced goods entering U.S. government supply chains. That work directly impacted military readiness, warfighter safety, first responder protection, federal procurement integrity, and the security of critical government systems.

Brian also served as Assistant Attaché at the U.S. Consulate General in Frankfurt, Germany, coordinating cross-border investigations across Northern and Central Europe involving counterproliferation, sanctions evasion, financial crime, pharmaceutical diversion, visa security, and transnational criminal networks. Earlier, as a Senior Special Agent and undercover operative in HSI Boston’s Counterproliferation Investigations program, he developed covert commercial platforms to identify illicit procurement networks seeking controlled U.S. technology for sanctioned, restricted, and high-risk end users.

Across his career, Brian worked with HSI, CBP, BIS, DOJ, DCSA, and other federal and international partners across counterproliferation, trade enforcement, supply chain security, procurement integrity, and national security investigations.

At Tesari AI, Brian leads National Security Applications, translating decades of investigative experience into product, workflow, and customer-facing applications of the platform. His role connects product, engineering, growth, and customer engagement, helping ensure Tesari reflects how high-stakes investigations and compliance decisions actually develop. He helps shape use cases across export controls, sanctions, government supply chain security, procurement integrity, and cross-border risk, with a focus on moving investigators and compliance teams from fragmented information to defensible decisions before the operational clock runs out.

Paul Wright

National Security & Strategic Threat Council

ex. Associate Director at Deloitte and KPMG • Principal Consultant at Verizon Business • Technical Director at Intel Security • Senior Advisor at Accuracy • Currently: Co-founder of The Coalition of Cyber Investigators • Founder of eCrime Intelligence

With more than 40 years in investigations spanning law enforcement, digital forensics, intelligence, and the private sector, Paul Wright brings a rare perspective on how modern investigations must operate in an increasingly complex digital world.

Paul began his career in law enforcement, where he developed deep operational experience investigating serious crime and complex financial offences. He later moved into the private sector, where he has held senior leadership roles, including Associate Director at Deloitte and KPMG, Technical Director at Intel Security, and Co-Founder of the Coalition of Cyber Investigators.

Across these roles, Paul has worked at the forefront of cybercrime, fraud, corruption, and financial investigations, becoming an internationally recognized expert witness trusted in complex cases where digital evidence, open-source intelligence, and investigative methodology must withstand legal scrutiny.

Paul is also a leading advocate for “Human-at-the-Helm” intelligence — the principle that advanced technologies, including agentic AI, should augment investigative judgement rather than replace it, providing investigators with faster access to critical intelligence while preserving the expertise and instincts that drive real investigations.
