G4S Risk Consulting has secured a three-year agreement with cricket's global governing body, the International Cricket Council (ICC).
G4S will offer security advice on matters of operational and strategic value to the ICC.
G4S Risk Consulting's Intelligence and Advisory Services (IAS) team will provide the ICC with bespoke security risk assessments covering its tournaments, Test, One-Day and T20 matches around the world.
The team will focus its services on many of cricket's key nations, including England, India, Pakistan, South Africa, Australia and the West Indies.
G4S will also produce daily monitoring reports and offer decision support to the ICC security team as it adapts to "complex and shifting security environments". The team has developed a bespoke assessment methodology for the ICC that will ensure "consistency and rigour in approach and delivery".
G4S has worked with the ICC for several years.
