OT Cybersecurity Professional
Abdulaziz Altamimi
About
I'm an OT cybersecurity engineer with hands-on experience protecting critical environments through monitoring, vulnerability management, access control, and secure configuration practices. I work across assessment and remediation workflows—reviewing logs and standards, hardening systems, managing patching schedules, and improving security posture through consistent operational discipline. I also use Python scripting to automate repeatable tasks and strengthen security processes.
