When a cyberattack hits a major event, the consequences rarely stay contained to IT systems — they show up at the gates, in the crowd, and on the stadium floor within minutes. This piece follows Crystal, an event security analyst managing a major sporting event, through three scenarios where digital incidents cascade directly into physical emergencies: a ticketing system breach, a compromised venue app, and a coordinated deepfake and drone threat. Each scenario illustrates the same underlying problem: most event security teams are still running separate workflows for cyber and physical threats, which means when the two converge, nobody has the full picture.
