Raison d’être

The Communications Security Establishment (CSE) is Canadaʼs national authority for foreign intelligence (Signals Intelligence) and the national technical authority for cyber security and information assurance.

CSE provides critical foreign intelligence to help inform the Government of Canadaʼs decision making on a wide range of issues, including national security.

CSEʼs sophisticated cyber and technical expertise helps identify, prepare for, and defend against threats to Canadaʼs most important systems and networks. CSE may also proactively stop or impede foreign cyber threats before they can damage Canadian systems, and conduct online operations to advance national objectives.

In addition, CSE provides technical and operational assistance to federal law enforcement, security partners, the Department of National Defence, and the Canadian Armed Forces.

The Minister of National Defence is responsible for CSE.
