Communications Security Establishment
/ˌsiː-ɛs-ˈiː/
n. “Canada’s silent guardian of secrets.”
CSE, or the Communications Security Establishment, is Canada’s national authority for signals intelligence, cybersecurity, and the protection of government information. Operating much like the NSA in the United States, CSE focuses on both offensive and defensive cyber operations, cryptographic analysis, and information assurance to safeguard Canadian government networks and interests.
