Principal Advisor

Stephen Leitch serves as an Executive Advisor for Fortress Cyber-Physical Security Advisors, where he helps government and commercial organizations integrate physical security, cybersecurity, governance, and enterprise risk into unified, sustainable security programs. Stephen brings more than 20 years of experience protecting critical infrastructure and leading complex security programs across the federal environment. As a senior leader with the Department of Homeland Security’s Federal Protective Service, he has overseen national countermeasure operations supporting approximately 8,500 federal facilities throughout all 50 states and U.S. territories. His experience includes directing more than $100 million in federal contracts, leading multidisciplinary security professionals, establishing governance and performance frameworks, overseeing physical and cybersecurity countermeasures, and advising senior DHS leadership on risk, resilience, compliance, and long-term security strategy. Stephen has also represented the Federal Protective Service within the Interagency Security Committee, contributing to the standards and risk-management practices used to protect federally occupied facilities. This perspective allows him to help organizations evaluate not only whether security controls are present, but whether they are properly governed, integrated, measured, and aligned with organizational risk. Stephen’s principal strength is his ability to bridge the traditional divide between physical security and cybersecurity. He helps executive teams understand how facilities, security technology, information systems, policies, personnel, vendors, and operational processes interact—and how weaknesses in one area can create risk across the entire organization. He holds the Certified Information Security Manager, Certified in Governance, Risk and Compliance, and Certified Protection Professional credentials. Stephen has passed the CPP examination and is awaiting completion of the Tier 3 eligibility process associated with his continuing CMMC assessor pathway. Through Fortress, Stephen brings clients the perspective of a national security executive who understands how to translate complex security requirements into practical governance, measurable performance, defensible investments, and resilient operations.

Joe brings extensive experience managing complex, multi-site security programs across federal facilities, healthcare environments, military installations, and corporate campuses. In his current leadership role with the Federal Protective Service, he oversees security operations supporting 147 facilities encompassing more than 17 million square feet.

At Fortress, Joe applies this experience to commercial offices, corporate campuses, healthcare facilities, industrial properties, retail environments, and other occupied spaces. He evaluates security from both an operational and technical perspective—examining how facilities are used, how people and assets move through them, how security technologies perform, and how effectively vendors, policies, and personnel support the organization’s risk-management objectives. Joe’s assessment approach is focused on delivering actionable recommendations rather than unnecessary complexity. He helps clients identify vulnerabilities, prioritize investments, improve vendor performance, strengthen emergency preparedness, and develop phased security improvements aligned with operational needs, available resources, and long-term business objectives.
