Threat Analyst at Centific Global supporting Microsoft email security and tuning rules to block phishing threats.

What I'm looking for

I'm building toward proactive, hypothesis-driven threat hunting.

At Centific Global (AAITS), I support Microsoft’s email security operations by triaging L1/L2 alerts with Microsoft Defender for Office 365 and Exchange Online Protection. I investigate phishing and malware threats by analyzing email headers, URLs, attachments, and indicators of compromise.

I’ve authored detection rules and mail flow policies to block suspicious URLs and domains and reduce false positives. I also document incidents and escalate validated threats to senior analysts; my work is informed by MITRE ATT&CK and my Certified Ethical Hacker (CEH v13) training.
