Mamadou Coulibaly

I am a cybersecurity systems analyst with hands-on experience securing mainframe and Windows environments, monitoring SIEMs, and supporting enterprise security tools.

At Texas Children’s Hospital I provided technical support, investigated security incidents, and monitored Splunk and Tenable to detect and respond to threats while supporting NIST CSF and ISO 27001 alignment.

I have a background in IT support and mainframe environments from work at Montgomery College, where I supported COBOL debugging (TSO, CICS), trained end users, and maintained service ticket documentation to improve troubleshooting efficiency.

I hold CompTIA Security+ and CompTIA CySA+ certifications and am pursuing an M.S. in Cybersecurity and Information Assurance; I focus on risk assessments, GRC tools (RSA Archer, ServiceNow GRC), and delivering clear, actionable security recommendations.
