Summary
🤩
RockstarMichael Henriksen is a Senior Vulnerability Research Engineer at GitLab with 11 years of hands-on experience in security engineering and tooling. Based in Copenhagen, he combines deep vulnerability research with pragmatic tool-building—authoring enhancements to popular open-source reconnaissance tooling like aquatone to add tagging, notes, and domain takeover detection. His work spans backend development, automation, and detection engineering, with a knack for improving reporting, Chromium screenshots, and user-agent handling to make reconnaissance outputs more actionable. Michael blends internet sleuthing instincts with disciplined engineering practices to turn investigative findings into reproducible tooling and mitigations. He’s equally comfortable diving into low-level exploit details and shipping reliable features that scale across security teams. An active open-source contributor, he quietly drives practical improvements that bridge research and production security.
