Ziyad Mehdawi

At SecurityMatterz, I investigate incidents across IT, IoT, and OT/ICS environments, preserving control-system evidence while supporting safe, continuous operations. I produce incident response, threat hunting, forensic, and recurring operational reports that engineering and business teams can act on.

I fine-tune detection rules and deploy SIEM use cases to expand monitoring coverage and reduce false positives. I also mentor L1 and L2 analysts in incident detection, analysis, and reporting.

Previously at Deloitte Financial Advisory, I contributed to digital and cyber investigations, disputes, and advisory engagements involving corporate and financial crime across the Middle East and internationally.

My background also includes teaching cybersecurity and ethical hacking, supervising graduation projects, and conducting network and web application penetration testing. I hold a BSc in Cybersecurity and Digital Forensics and certifications spanning incident handling, industrial defense, digital forensics, threat defense, and security analytics.
