About This Event

The Global Security Exchange (GSX) is the preeminent international security trade show and conference, organized annually by ASIS International—the world’s largest professional organization for security management practitioners. GSX brings together security leaders and practitioners from across industries, including corporate security, physical security, cybersecurity, risk management, emergency management, and public safety, for a multi-day immersive experience featuring education sessions, keynote presentations, and an expansive exhibit hall with 500+ exhibitorsshowcasing state-of-the-art security solutions and services. The event spans three days of in-depth programming designed to help attendees understand emerging threats, explore innovations, and connect with global peers to advance the profession.

One of GSX’s core benefits is its robust educational agenda—with more than 200 expert-led sessions covering critical topics such as active assailant response, physical and cyber risk convergence, enterprise security risk management, and evolving technology trends—many of which qualify for continuing professional education credits (CPEs). These sessions, alongside high-profile keynote talks and specialized content tracks, give attendees actionable insights and strategies that can be implemented within their organizations to strengthen security posture and resilience.

Another major advantage of attending GSX is the networking and industry engagement opportunities. The trade show floor and related social events draw tens of thousands of security professionals, enabling meaningful face-to-face interactions with solution providers, industry leaders, and peers from around the world. This makes GSX ideal for Chief Security Officers (CSOs), security directors and managers, risk and compliance professionals, cybersecurity specialists, consultants, and law enforcement partners looking to stay ahead of threats, evaluate new technologies, build strategic partnerships, and share best practices that drive impact across their organizations.
