At EY (Ernst & Young), I deliver cyber threat intelligence for clients across sectors, producing threat reports, emerging threat advisories, and vulnerability advisories with validated IOCs and detection guidance.

I author Targeted Threat Intelligence Reports that combine threat landscape and digital exposure analysis for clients’ GRC assessments. I also support red team operations with OSINT-driven reconnaissance to map organisational exposure and attack surfaces.

I built a CVE enrichment tool and a look-alike domain detector that together save an estimated 8–10 analyst hours per week. I also served as CTI SPOC for an AI tool automating recurring reports and advisories, partnering with developers through build and deployment.

I monitor surface, deep, and dark web sources for exposed credentials and data, and have detected phishing sites, fraudulent domains, and rogue mobile apps for takedown. I’ve mentored junior analysts in CTI operations, OSINT, and MITRE ATT&CK mapping, and received the EY Achiever Extraordinary Award.
