As the oldest Auxiliary Police Force with a monopoly over most of the private armed security sector in Singapore for 33 years, Certis maintains a visible presence in many key establishments, including the private residences of VVIPs. They were deployed in major events such as the Singapore 2006 IMF Meetings, the New Year Countdown at Marina Bay in 2007 and 2008, the Chingay Parade and the Thaipusam processions. They also continue to dominate some services such as the transportation of valuables, most visibly in the form of delivering cash to automated teller machines.
