Abstract

The increasing frequency and complexity of data breaches present critical challenges for cybersecurity managers responsible for protecting organizational assets. This qualitative phenomenological study examined how information technology (IT) managers conceptualize, strategize, and apply best practices to prevent breaches in complex environments. Unmanaged risks can compromise sensitive systems, disrupt operations, and erode stakeholder trust. Business and IT leaders must proactively address these threats to avoid reputational damage, financial loss, regulatory penalties, and loss of competitive advantage. Grounded in Actor-Network Theory (ANT), the study examined insights gathered from 20 experienced IT managers in multiple countries, using semi-structured questionnaires and organizational documents. Thematic analysis revealed three core themes: the role of human factors in breach incidents, systemic technological vulnerabilities, and the value of socio-technical relationships in cybersecurity risk scenarios. Findings highlight the need for a multidisciplinary, multi-layered, and change-ready cybersecurity model that integrates technical defenses with human-centered and organizational practices. A key recommendation is for organizations to adopt socio-technical approaches that enhance cybersecurity readiness. The implications for positive social change include improved protection of customer data, reduced business losses, sustained public trust in digital systems, and a more resilient information ecosystem.
