What Is the DSS/SSS?

The DSS/SSS is one of Nigeria’s most powerful security agencies. It was established in 1986 when the National Security Organization (NSO) was restructured by the then military government.

It now serves as the intelligence arm of the Presidency, reporting directly to the National Security Adviser (NSA).
