Before 1997, it was named the Security Branch. Before 1973 it was known as the Defence Branch.


In February 2021, after reports that the Security Bureau worked with the Correctional Services Department to force prisoners with dual passports to declare a sole nationality, the Security Bureau cited mainland China's nationality laws to explain why consular visits to those prisoners with dual passports might be rejected.[2] A spokesman for the British consulate said they were now "seeking answers from the Hong Kong authorities following the suggestion that they may withdraw our consular access to dual national prisoners and prevent us providing the support we have given since 1997."[2]

In January 2021, a proposal from the government was announced, where information of airline passengers would be shared with the Immigration Department and passengers could potentially be banned from flying.[3] In response to criticism that it could lead to preventing Hong Kong citizens from leaving the city, the Security Bureau claimed that they would not be affected, and that this would only be for "passenger information on flights heading to Hong Kong, rather than departing flights. The right of Hong Kong residents to enter or leave Hong Kong is not affected."[3]
