Private security companies are businesses that provide security services to individuals, organizations, and governments. They offer a range of services, including armed security guards, surveillance systems, and event security. These companies are often hired to protect property, assets, and people, especially in areas where public law enforcement may not be sufficient. These companies operate independently from government agencies and can be found in various sectors, such as retail, corporate, and residential security. Their personnel may include trained security officers, investigators, and consultants who assess risks and develop security plans tailored to specific needs.
