I am a cybersecurity leader and consultant with 12+ years of experience helping organizations strengthen their security posture, reduce cyber risk, achieve compliance, and build resilient security programs across banking, telecommunications, managed security services, and enterprise environments.
As a virtual Chief Information Security Officer (vCISO), I support organizations that need executive-level cybersecurity leadership without the cost of a full-time CISO. I help businesses define security strategies, establish governance frameworks, manage cyber risks, improve compliance readiness, and align security investments with business objectives.
My experience includes leading enterprise cybersecurity programs, managing Security Operations Centers (SOC), overseeing incident response, conducting vulnerability management, coordinating penetration testing activities, implementing security controls, and advising senior leadership and boards on cyber risk.
