Security management in multi-campus private universities presents unique challenges due to decentralised operations, campus diversification, and the need to balance safety with academic freedom. This paper explores professionalism, policy gaps, and governance implications in security management at Presbyterian University, Ghana (PUG), a multi-campus private institution. Using a qualitative case study design, data were collected through document analysis, semi-structured interviews with campus security staff and administrators, and literature review. Findings reveal significant gaps in formal security policies, inconsistent professional practices, and governance ambiguities across campuses, which undermine security operations and risk management effectiveness. The study recommends standardised security policies, professional training systems, integrated governance structures, and stakeholder engagement mechanisms. These findings have practical implications for administrators, policymakers, and security practitioners in Ghanaian private higher education and similar contexts.
