@osarumeerebor
Seasoned information and cybersecurity risk leader driving enterprise security, compliance, and resilience.
What I'm looking for
I am an experienced information and cybersecurity risk leader with a long career in banking and IT services, focused on operational risk, cyber risk frameworks, and compliance. I have led enterprise-wide security programs, vulnerability management, and major IT transformation projects.
At First Bank I served as Assistant General Manager — Head, Information/Cybersecurity Risk, implementing risk frameworks, managing ISO 27001/PCI/ SWIFT CSP compliance, third-party risk management, and reporting to management and board committees. I previously reduced active vulnerabilities by 90% while leading security monitoring functions and serving as Deputy CISO.
My background includes hands-on delivery of large projects such as core banking migrations, data center moves, and cloud/DevOps initiatives, combined with early-career roles in IT operations, application consulting, and systems administration. I hold multiple certifications including CISM, CDPSE, ISO lead implementer/auditor credentials, PCI certifications, COBIT 5, and MIT CSX training.
I emphasize pragmatic security that enables business objectives: aligning governance, technical controls, and incident management to strengthen resilience and regulatory compliance while supporting digital transformation and innovation.
