About Shreyas Kumar Tumkur Shivakumar
Cyber Risk Analyst specializing in Operational Technology (OT) security and critical infrastructure protection, with experience across IT–OT convergence, cyber risk management, and governance.I currently work at Chevron, supporting cyber risk initiatives focused on securing industrial (Oil and Gas) Operational Technology environments. My background spans consulting and MSSP environments, where I’ve contributed to security programs, risk assessments, compliance efforts, and stakeholder engagements across complex enterprise and OT landscapes.My professional foundation was shaped at EY, where I developed a strong understanding of risk-based security, controls, and business-aligned cybersecurity strategy. I’m known for taking ownership, communicating risk clearly to technical and non-technical stakeholders, and standing firm on security principles when it matters.I believe effective cybersecurity leadership goes beyond tools where it requires context, accountability, and strategic thinking to protect operations that truly matter.Core focus areas:Cyber Risk Management | OT & ICS Security | Critical Infrastructure | GRC | IT–OT Convergence | Security Strategy | Risk Assessment | Compliance | Stakeholder Management
