About Cybersecurity in Canada
Cybersecurity covers threat detection and response, identity and access management, encryption and key management, application and cloud security, security operations tooling, and the specialised products defending critical infrastructure and operational technology.
Post-quantum and quantum-safe cryptography sits on the boundary between this sector and Quantum, and companies working on it are tagged in both.
