FOUNDER & CHIEF EXECUTIVE OFFICER

Wesley Bull

Wesley Bull is the Founder and Chief Executive Officer of Sentinel Resource Group. His experience cuts across the seats his clients and their advisors each hold singly: security, intelligence, enterprise risk, law, finance, and board accountability. He advises Fortune 50 boards, family offices, private capital, and the counsel who serve them, so that decisions about protection rest on intelligence rather than assumption.

About
Wesley Bull

Three decades protecting people, places, and the assets that matter most, from law enforcement and high-threat operations to the boardrooms of some of the world's most consequential companies.

Clarify your risks. That is the discipline Wesley Bull built Sentinel Resource Group to practice, and the premise most security programs still get backward: they reach for defenses before they understand the risks they actually carry. Threats surface in one domain, but they are conceived and enabled across several. Bull founded SRG to close that gap, bringing an integrated intelligence-led asymmetric threat lens to Fortune 50 boards, high-growth technology companies, private capital, distinguished family offices, and the counsel who advise them.

Bull's career spans more than three decades, beginning in law enforcement, public safety, specialized task force assignments, contract work for U.S. intelligence agencies and executive roles for iconic companies. Before founding SRG, Bull served as the senior-most global security and safety executive at NVIDIA, overseeing security for the company's classified government programs and directing the convergence of physical security, security technologies, supply chain security, IP protection, insider threat, counterintelligence, and executive protection across one of the world's most strategically targeted technology companies. Earlier, as board-appointed Chief Security Officer and Vice President of Enterprise Risk Management at First Republic Bank, he built the institution's first enterprise risk program in the aftermath of the 2008 financial crisis, also directing bank security operations, cybersecurity program strategy, and the bank's financial crimes intelligence and investigations unit.

A dedicated lifelong learner, Bull’s formal academic accomplishments span pre-medicine, forensics, law, terrorism and counterterrorism and an MBA, in addition to myriad specialized training certifications. He grew up living across multiple countries and has carried that international orientation into professional work across complex and volatile environments abroad. The result is an adviser who can assess the breadth of operational, reputational, legal, financial, and complex security risks as a single picture, synonymous with how the threat actor sees it.

Bull is the author of the forthcoming book The Appearance of Protection: Governing Family Office Security in an Era of Asymmetric Threats. He has spoken on asymmetric risk and emerging threats at the Spear's Summit in Abu Dhabi and London, and before legal, private banking, wealth management, and finance audiences internationally. His analysis has appeared in CNBC and across the security and risk press, including Cyber Security Review, Security Magazine, and Security Management, with contributions to Business Insider. He has been recognized since 2024 as a Top Recommended Adviser in the Spear's 500 Security, Intelligence & Investigations Index.
