Cybersecurity Architect at Siemens Healthineers who streamlined SaaS risk assessments and established security exception governance.

India

Message

At Siemens Healthineers, I lead cybersecurity consulting for application security assessments and SaaS supplier risk assessments. I developed vendor questionnaires, risk classifications, approval workflows, and centralized risk registers to streamline assessments.

I also established governance processes for security exceptions, covering high- and critical-risk reviews, escalation approvals, remediation tracking, and risk acceptance. My work includes defining assessment criteria for browser extensions, Figma plugins, and client software, as well as AI-enabled compliance assessments.

Before Siemens Healthineers, I assessed cybersecurity for oil and gas clients at Deloitte using NIST guidance, and worked across application, cloud, IT, and OT security at Infosys Ltd., Wipro Ltd., Amdocs (Payroll - RNT), LEONI, and Powervision. I hold CISSP, CEH, and CCNA certifications.
