Critical Infrastructure Protection — Our Core Focus
InfraMetric specializes in the quantitative analysis of Critical Infrastructure Interdependency (CII), applying econometric and statistical methods to make infrastructure risk measurable, reproducible, and defensible. Our work directly supports risk management decision-making by replacing intuition-based approaches with empirical, standardized metrics that governments, operators, and policymakers can act on with confidence.

Critical Infrastructure Interdependency (CII) Analysis
Applying econometric input-output modeling and supply-chain statistics to measure, forecast, and communicate interdependency risks across infrastructure sectors. Our metrics-based approach produces decision-ready risk intelligence — enabling evidence-based investment, policy, and operational choices.

  • Quantitative risk measurement training
  • Interdependency forecasting & scenario analysis
  • Cross-border dependency analysis (Canada–U.S.)
  • Risk management framework development

About the Founder — Tyson Macaulay
Tyson Macaulay is the Founder of InfraMetric Analytics Inc., a Canadian firm specializing in Critical Infrastructure Protection (CIP) and Critical Infrastructure Interdependency (CII) analysis. He has over 25 years of professional experience in cybersecurity, networking, enterprise systems, and critical infrastructure environments.
Macaulay is Deputy Director of the National Centre for Critical Infrastructure Protection, Security and Resilience (NC-CIPSeR) at Carleton University, Ottawa, Canada, where he is also an alumnus. In this role he leads peer-reviewed research, supports graduate mentorship, and contributes to Canada's national CIP knowledge base. His research applies econometric input-output modeling to produce quantitative, reproducible, and defensible risk metrics — enabling decision-makers in government and industry to move beyond intuition-based risk management toward evidence-driven infrastructure protection strategies.
He is the author of four books on infrastructure security, risk management, and decision support, holds two patents, and has published numerous peer-reviewed journal articles and conference papers. His Google Scholar profile records 980 citations and an h-index of 9 (as of 2025). He presented at RSA Conference 2025 on cross-border Canada–U.S. critical infrastructure interdependencies and supply chain risk metrics.
Macaulay contributes to international and professional standards development as a volunteer with the International Standards Organization (ISO), Professional Engineers of Ontario (PEO), and the Internet Engineering Task Force (IETF). His professional experience spans enterprise cybersecurity, high-performance computing (HPC) infrastructure, data centre security, telecommunications, and critical infrastructure sectors across Canada and internationally.
