Communications Security Establishment
The Communications Security Establishment (CSE) is one of Canada’s key security and intelligence organizations, focussed on collecting foreign signals intelligence in support of the Government of Canada’s priorities, and on helping protect the computer networks and information of greatest importance to Canada. We also provide assistance to federal law enforcement and security organizations in their legally authorized activities, when they may require our unique technical capabilities.
We are in the process of moving our services and information to Canada.ca.
Our current Communications Security Establishment website will remain available until the move to Canada.ca is complete.
