About Casey McDannald
I’m a security‑focused IT professional with hands‑on experience in security infrastructure, email security, vulnerability management, and endpoint and identity support, working toward a long‑term career in cybersecurity.Previously, I worked as a Security Infrastructure Engineer at Talkiatry, where I was part of the team responsible for deploying Proofpoint Email Protection across the organization. In this role, I designed and configured custom email security policies, including spam filtering and attachment inspection, created security documentation and user guidance, and monitored security alerts to identify and remediate malicious email threats. This experience strengthened my interest in blue‑team operations and threat defense.I also bring direct experience in vulnerability management, having worked as a Vulnerability Management Analyst at American Car Center. I used Rapid7 InsightVM to identify vulnerabilities tied to missing Patch Tuesday updates, manually remediated vulnerabilities by deploying operating system and application patches, and verified successful remediation through Rapid7 re‑scans. This role gave me hands‑on exposure to the full vulnerability lifecycle—from detection through validation.
