01 WHOAMI

AI-assisted reconnaissance. Manually verified offensive security.

GK Data LLC is a focused offensive security consultancy led by Garrett Kohlrusch, a security researcher with 5+ years of hands-on testing and 100+ validated vulnerabilities across major companies, government systems, and consumer-scale platforms.

The work is intentionally practical: web application and API penetration testing, mobile app security testing, network and external attack surface review, cloud configuration review, and WordPress-focused website security management for small businesses.

GK Data uses custom AI agents to accelerate reconnaissance, correlation, and documentation strategy. Those agents help organize signals and surface paths worth testing, but they do not replace validation. Findings are manually reproduced, reviewed, and impact-tested before they become deliverables.

No AI slop. No unverified scanner noise. The goal is clear evidence, real impact, and remediation guidance teams can use.
