The private security industry in South Africa is an industry providing guarding, monitoring, armed reaction, escorting, investigating and other security-related services to private individuals and companies in the country. The private security industry in South Africa is the largest in the world, with nearly 9,000 registered companies and 400,000 registered active private security guards, more than the South African police and army combined. This is attributed by some to the country's former high levels of crime to a lack of public funds from Parliament towards the South African Police Service (SAPS) or to an increasing trend in many countries towards government outsourcing of certain security functions.
Street violence occurred during the 2006 security strike.
In 2006, private security personnel went on strike across South Africa. The strike lasted 96 days and cost the industry more than a million working days. The strike was supported by the South African Transport and Allied Workers Union and 15 other trade unions. The striking workers looted and damaged property, and committed violent crimes.
