Canada’s new Critical Cyber Systems Protection Act (Bill C-8) introduces a strict 72-hour cyber incident reporting mandate. Find out how Tenable is helping critical national infrastructure operators bridge the IT/OT divide to ensure full compliance. Key takeaways: Bill C-8 introduces stringent new cyber incident reporting requirements and heavy financial penalties for critical infrastructure operators. Eliminating network blind spots with a hybrid IT/OT discovery approach, including Safe Active Querying for isolated, hard-to-reach process-control systems, enables operators to establish a required security baseline. Predictive Vulnerability Priority Rating (VPR) scoring helps you prioritize and focus limited resources on the critical flaws that actually threaten physical safety and uptime. Advanced multi-detection engines and seamless IT workflow integrations accelerate mean-time-to-respond (MTTR) to help both security teams and operators align with a strict 72-hour reporting requirement. With the enactment of Canada’s Critical Cyber Systems Protection Act (CCSPA), commonly known as Bill C-8, the Canadian federal government is laying down a clear framework to protect the cyber-physical systems that are vital to national critical infrastructure security. For designated operators in telecommunications, energy, transportation, and banking, the mandate is clear: Establish formalized cybersecurity programs, mitigate supply chain risks, and — most critically — report cyber incidents to authorities within 72 hours. Failure to comply carries heavy consequences, including penalties that can reach up to $15 million Canadian dollars (CAD). But beyond the threat of fines, Bill C-8 highlights a fundamental operational challenge that many industrial organizations are still struggling to solve: How can you detect, investigate, and report a breach in 72 hours when you lack unified visibility across your converged IT and OT environments? Requirements for meeting Bill C-8's 72-hour incident reporting mandate In modern industrial operations and critical infrastructure, the line between IT and OT continues to blur. The introduction of connectivity (e.g., IoT-connected cameras and building management systems) has optimized processes and service delivery, but it has also introduced new cyber exposures. Today, threat actors do not honor traditional network silos; they frequently compromise a web-facing IT asset or IoT device and move laterally into the operational technology (OT) environment to disrupt physical processes. Meeting a 72-hour incident reporting window is nearly impossible if your security team is relying on fragmented point solutions. Solutions that focus exclusively on passive OT network monitoring often leave massive blind spots — especially considering that IT and IoT devices can constitute up to 50% of an industrial environment. When an incident occurs, teams waste precious hours manually correlating alerts across disconnected tools rather than actively investigating the root cause. To comply with CCSPA and protect uptime, critical national infrastructure (CNI) operators must bridge the IT/OT security divide. Establish your CCSPA cybersecurity baseline The CCSPA requires operators to implement formalized cybersecurity programs. The foundation of any mature security program is a comprehensive asset inventory — you cannot secure what you cannot see. The Tenable One Exposure Management Platform helps organizations eliminate security blind spots by building a complete, unified inventory of all OT, IoT, and IT assets. Tenable goes beyond passive-only network monitoring with our proprietary Safe Active Query technology. This hybrid approach safely communicates with industrial devices in their native protocols to uncover significantly more assets than passive monitoring alone — including dormant process control systems, shadow IT, and unmanaged IoT — without disrupting process integrity or impacting equipment uptime.
