Markham Daly
Cybersecurity Analyst | Email Security | IT Risk
Cybersecurity analyst with hands on experience across email security, DNS analysis, IT risk, vulnerability assessment, and infrastructure security. I am focused on continuing to learn across security domains, strengthening my technical foundation, and communicating clearly with both technical and nontechnical people.
My work has included DMARC, SPF, and DKIM analysis, customer support for DNS and deliverability issues, port security compliance exposure, penetration testing with ZAP and Nmap, and network segmentation through both enterprise observation and self hosted lab work. I am focused on growing into security consulting and engineering roles where technical depth, judgment, and communication matter.
