I'm leading global vulnerability management and cybersecurity compliance at Parker Meggitt, where I achieved 100% scan coverage across known internal and external assets and reduced internal exploitable vulnerabilities by 80%.

I design unified control frameworks mapping ISO/IEC 27001, NIST SP 800-171, and regional requirements, while governing ISMS documentation and audit-ready compliance processes. I also provide senior leadership with clear vulnerability trends, risk indicators, and remediation reporting.

At Arup, I led Cyber Essentials Plus certification and vulnerability management across an environment of 25,000 users and more than 100,000 network devices. I deployed Rapid7 InsightVM and Intsights, strengthened security policies, and guided the response to a key vendor security breach.

My earlier work at KPMG and EY included web application and network penetration testing, VAPT, risk management, configuration reviews, and audits. I bring over 12 years of experience helping organisations turn security findings into practical, business-aligned improvements.
