I reduce cyber risk through vulnerability management, threat intelligence, and security operations in regulated environments.

Message

I'm reducing cyber risk across South Eastern Health & Social Care by prioritising Tenable findings against exploitability, asset criticality and patient impact, while cutting critical patching delays from 21 days to 9 days. I also investigate and contain 11+ incidents monthly using Wazuh and Sophos XDR, reducing response time from two hours to 45 minutes.

Previously at Amdari, I accelerated patch deployment by over 60% through Ansible automation, built Wazuh detections for APT activity, and turned 500+ MISP indicators into actionable blocklists and executive reporting. My experience spans regulated healthcare, financial services and enterprise environments, combining vulnerability remediation, incident response, cloud security, threat intelligence and compliance evidence.
