Keeping Singapore Safe and Sovereign for All Singaporeans
As part of the Home Team, the Internal Security Department (ISD) confronts and addresses Singapore's security issues and latent threats.
Over the years, ISD and its predecessor, Special Branch, have dealt with many threats to Singapore’s internal stability, security and sovereignty. Find out more about what we do, how we work and how we deal with threats.
Security agencies alone cannot detect every radicalised individual or terrorist threat in Singapore. The community also plays an important role. Find out how you can do your part.
An intelligence career with the ISD lets you make a difference by keeping Singapore safe from internal security threats.
