Marcus Hayden

Enterprise Security Operations Leader

HCL Software

Marcus leads large-scale vulnerability and patch operations strategy for Fortune 500 enterprises and federal agencies across North America and LATAM. With over a decade advising on security operations at scale, he has built expertise in closing the gap between security capability and operational execution, from remediation velocity to compliance automation. His work has helped organizations achieve 98%+ patch compliance while dramatically reducing friction between security and IT operations. Recent engagements include enabling critical infrastructure to deploy high-risk patches to 100K+ endpoints at 99% success rates, and implementing SecOps/ITOps integrations that eliminated manual scanning workflows and reduced mean time to remediation by roughly 80 hours monthly. Before HCL, Marcus supported high-stakes operational transformation in construction and financial markets, including the international security infrastructure for a major Olympic bid effort. That experience shaped his understanding of how organizations scale security when the stakes are highest, visibility is greatest, and the margin for operational failure is smallest.
