Securing Public Gatherings (SPG)

Public gatherings and crowded places are increasingly vulnerable to terrorist attacks and other extremist actors because of their relative accessibility and large number of potential targets. Organizations of all types of sizes, including businesses, critical infrastructure owners and operators, schools, and houses of worship face a variety of security risks.

To help organizations mitigate potential risks in today’s dynamic and rapidly evolving threat environment, CISA provides a compendium of resources for securing public gatherings. These resources cover the numerous threat vectors in CISA’s portfolio, including unauthorized access to facilities, cybersecurity, election security, active shooters, bombings, and small unmanned aircraft systems (sUAS).

The Mass Gathering Security Planning Tool

The Mass Gathering Security Planning Tool is a new Cybersecurity and Infrastructure Security Agency (CISA) product. This tool provides event planners with a framework to begin or continue planning efforts for a mass gathering or special event and to connect stakeholders to the suite of tools and resources provided by CISA and its partners.

This tool contains a combination of background information, event-planning checklist items, and venue characteristics, as well as suggested planning considerations based on the information entered.

The output of the tool is a report that is downloaded by the user - not submitted to CISA in any way - that outlines existing features at the venue and can inform ongoing collaboration among planning team members, law enforcement personnel, and first responders. Additionally, the output is not meant to identify every possible detail for consideration in a mass gathering plan, but rather to identify an overarching framework for developing sound plans. The resources provided within this tool and in the downloadable report will point planners to credible resources to find best practices related to mass gatherings and event planning.
