Liam O. Email and Phone Number
With over a decade of experience in information security, I lead the IT Security and Governance function at Emeria UK, a European leader in residential real estate services. I oversee the security strategy, audit, risk, and incident response for a growing workforce of 5,000, ensuring the protection of critical systems and data. I hold multiple certifications, including CISSP, CISM, and an MBA in Risk and Resilience.My passion for cyber-resilience stems from facing diverse and evolving cyber threats in various sectors, such as finance, healthcare, and pharmaceuticals. I have developed and implemented robust security frameworks, processes, and solutions, aligned with industry standards and best practices. I have also conducted extensive research on cyber-resilience for SMEs, addressing the challenges and opportunities in this domain. I enjoy sharing my knowledge and insights through security awareness training, publications, and speaking engagements. Outside of work, I like to experiment with VMs in my home lab, spend time with my Bullmastiff, and savour my morning coffee.
