Meet the advisor
Executive cybersecurity guidance, from a trusted advisor.
Johan Iruthayananthan is a trusted cybersecurity executive with over 15 years of experience leading national and global cybersecurity, cyber risk, and resilience programs for complex organizations, including senior information security leadership at a Canadian tier-one bank. He helps executives and business leaders reduce cyber risk, strengthen resilience, and align cybersecurity with business strategy.
After more than 15 years leading cybersecurity and cyber risk programs for complex organizations, Johan founded Cyber Risk Office to make executive-level cybersecurity guidance accessible to businesses of all sizes. He recognized that many organizations face growing cyber threats but lack the resources for a full-time Chief Information Security Officer (CISO). Cyber Risk Office was created to bridge that gap, providing practical, business-focused advice that helps leaders reduce risk, strengthen resilience, and make confident decisions without unnecessary complexity.
