Aetos Security Management

Since its inception, AETOS has integrated the auxiliary police forces of Changi International Airport Services, PSA Corporation, and ST Kinetics as part of a consolidation initiative led by Temasek Holdings.

In 2007, the company participated in a joint security exercise at the Brani Container Terminal alongside PSA Singapore Terminals, the Singapore Police Force, and the Ministry of Defence to simulate a response to a security incident.

On 13 October 2016, AETOS was acquired by Surbana Jurong, a Singaporean government-owned consultancy focused on infrastructure and urban development.

In 2016, due to recruitment challenges among Malaysian and Singaporean nationals, the company began recruiting Taiwanese nationals for auxiliary police roles. In 2018, several Taiwanese officers were deployed to land checkpoints alongside Singaporean staff. Radio Taiwan International reported that some recruits faced job-related stress at their assigned posts.

On 26 January 2018, AETOS opened its new headquarters at 5 Corporation Drive, Jurong West, which includes a command centre, indoor shooting ranges, and a cash processing centre.

In January 2019, an AETOS officer stationed at the Woodlands Checkpoint was found dead with a gunshot wound to the head.

In September 2019, AETOS signed a teaming agreement with TRD Singapore to provide countermeasure services against unmanned aerial vehicles (UAVs) in Singapore. In November, the company signed an agreement with COSEM Safety & Security Services to provide integrated security and safety consultancy.

On 15 April 2021, an AETOS officer was arrested for the alleged armed robbery of a lender using a Taurus Model 85 revolver that he had reportedly brought unlawfully after reporting for duty.
