The three types of G4S security officers are Property Resource Officers, Upscale Security Officers and Custom Protection Officers. All personnel are screened according to talents, qualifications and experience.
Property Resource Officers must possess an associate degree or have previous experience in customer service, public security, police or military positions. To become Upscale Security Officers, candidates must also pass an extensive background investigation and attend a 40-hour classroom certification program. Custom Protection Officers have all the qualifications of the other two positions and must possess a degree in either criminal justice, police science or security administration or have previous certification and experience as law enforcement or military professionals.
