With a summer packed with major public gatherings, the federal Cybersecurity and Infrastructure Security Agency is urging event organizers and attendees to sharpen their focus on physical security, highlighting the risk of improvised explosive devices and other threats that can accompany large crowds and complex logistics.
CISA pointed to the FIFA World Cup 2026™ and commemorations tied to America’s 250th anniversary as examples of once-in-a-generation events that draw massive audiences and require extensive coordination. While the agency is best known for combating cyber threats, it underscored its parallel role in helping communities harden venues and infrastructure against physical attacks.
Through its Office for Bombing Prevention, CISA is expanding outreach to state and local partners, venue operators, and the public, offering no‑cost training, security planning materials, and protective guidance. The initiative promotes suspicious-activity reporting and provides tools designed to reduce risk and improve preparedness across jurisdictions.
A central pillar of the effort is awareness: teaching people how to recognize suspicious behavior or items and what steps to take if they encounter them. The agency’s resources also address emerging concerns such as unmanned aircraft systems near venues. Materials are available at www.cisa.gov/FIFAWC.
CISA is encouraging communities and organizations to incorporate these tools into pre‑event planning, tabletop exercises, and staff training, and to share information broadly across networks so frontline personnel and volunteers have a common picture of risk.
Members of the public are being urged to review the guidance ahead of high‑visibility events, stay alert at venues and transit hubs, and report concerns to authorities. Additional information on physical and cybersecurity resources tied to this summer’s events can be found at www.CISA.gov/FIFAWC.
The agency reiterated the national campaign message: “If You See Something, Say Something.”
