What we do at CSEC

CSEC is Canada's national cryptologic agency. Unique within Canada's security and intelligence community, CSEC employs code-makers and code-breakers to provide the Government of Canada with information technology security (IT Security) and foreign signals intelligence (SIGINT) services. CSEC also provides technical and operational assistance to federal law enforcement and security agencies.

Our IT Security products and services enable our clients (other federal government departments and agencies) to effectively secure their electronic information systems and networks. CSEC also conducts research and development on behalf of the Government of Canada in fields related to communications security.

Our SIGINT products and services support government decision-making in the fields of national security, national defence and foreign policy. CSEC's SIGINT activities relate exclusively to foreign intelligence and are directed by the Government of Canada's intelligence priorities.
