How OSINT identifies violent hooligan groups before events
A case study in open-source intelligence collection, network mapping, and threat assessment for event security teams.
Open-source intelligence (OSINT) enables security teams to identify violent hooligan groups by collecting and analysing online signals before disorder occurs. Fivecast ONYX applied this approach ahead of a major football tournament, moving from platform-wide collection to identified people of interest.
Violent hooligan networks coordinate through open platforms – planning meetups, targeting rivals, and discussing travel routes in the days before fixtures. Standard monitoring approaches struggle with the volume; a structured OSINT methodology surfaces what matters.
What does this case study cover?
- How to scope OSINT collection for a major sporting event
- What separates general fan activity from indicators of planned violence
- How multimedia analysis and OCR surface threats in images and screenshots
- How network analytics identify coordinators and people of interest in hooligan groups
- What proportionate mitigation looks like when intelligence reaches individual level
Who is this case study for?
Analysts and intelligence managers responsible for threat assessment ahead of major sporting fixtures. If you work in event security, public order intelligence, or law enforcement and need a methodology that scales under time pressure, this case study is for you.
