About
William Asare Yirenkyi
Tech Audit, Cybersecurity and GRC CISA and CISM. ex-Big4. Creating clarity at the intersection of systems, security, and compliance.
I’m a technology auditor and cybersecurity professional with experience across SOX ITGC, IT risk, and platform control reviews. My background includes years of experience at PwC in Risk Assurance and Cybersecurity, followed by independent IT audit work across Windows, UNIX, and core ITGC domains. I combine audit judgment with technical execution, building tools like AuditAI and AuditLens to improve control mapping, evidence quality, and audit defensibility across frameworks such as NIST AI RMF, ISO 42001, SOX ITGC, NIST 800-53, and CSF 2.0. I hold CISA, CISM, Security+, eJPT, and cloud certifications, and I am completing an MSc in IT Auditing and Cybersecurity at Temple University’s Fox School of Business with a 4.0 GPA.
