Senior🎓
Top SchoolSean Gallagher is a security research engineer at Cisco Talos with a decade of hands-on threat research and over 20 years of journalism experience translating complex national security and infosec topics into actionable analysis. He investigates cybercriminal TTPs, web- and social-media-based scams, malvertising and ransomware, blending telemetry-driven analysis (Python, SQL, Kibana) with clear, publishable storytelling honed at Ars Technica and Sophos. A former Navy officer, he pairs operational discipline and blue-team thinking with a lab-oriented, code-tinkering curiosity that surfaces subtle privacy and threat vectors others miss. Sean has led annual threat reporting, collaborated closely with incident response and AI teams, and routinely explains technical risks to both specialist and general audiences. Based in the Washington DC–Baltimore area, he brings a rare mix of editorial rigor, investigative instincts, and practical security engineering to threat intelligence.
