This will depend on the type of event, the venue, and the number of people attending. For example, a corporate event with 100 attendees is very different from a festival or concert with multiple thousands. The standard recommendation is to have one security guard for every 100 attendees. This is a guideline and may vary depending on the specific circumstances of the event. We always recommend a pre-event security assessment by our experts that will take into consideration all risk factors, local event regulations, and physical layout. You can be sure that we have the resources to supply any number of security personnel.
