Canadian Cyber Incident Response Centre (CCIRC)

CCIRC helps ensure that many of the services which Canadians rely on daily are secure. It assists in securing the vital cyber systems of provinces, territories, municipalities and private sector organizations while collaborating closely with partners, including international counterparts and information technology vendors.

Many of CCIRC's products are available to the public, and the expertise of its highly trained and experienced staff is drawn upon to share information on cyber threats with partners. Additionally, when CCIRC becomes aware of malicious activities, it takes steps to notify owners of compromised systems, focusing on computers in critical infrastructure and provincial, territorial, or municipal government.

CCIRC highly recommends that organizations implement the Top 4 Strategies to Mitigate Targeted Cyber Intrusions. These strategies are among the most effective steps an organization can take to protect its systems against targeted cyber attacks. These strategies have been endorsed by numerous parties, including the Communications Security Establishment Canada (CSEC). By implementing these four strategies, organizations can prevent as much as 85% of targeted cyber attacks.


In support of Public Safety Canada's mission to build a safe and resilient Canada, CCIRC contributes to the security and resilience of the vital cyber systems that underpin Canada's national security, public safety and economic prosperity.

As Canada's computer security incident response team, CCIRC is Canada's national coordination centre for the prevention and mitigation of, preparedness for, response to, and recovery from cyber events. It does this by providing authoritative advice and support, and coordinating information sharing and event response.
