Monitor and respond to
physical and cyber threats.
Building a platform that monitors and responds to both physical and cyber threats. Designed by an engineer who spans security and AI implementation end to end.
What We Provide
Security Diagnosis
Vulnerability assessment and penetration testing for web applications, APIs, and AI systems. Based on OWASP Top 10, OWASP LLM Top 10, and MITRE ATLAS.
Secure System Development
Zero Trust architecture design and implementation. From requirements definition to production — one engineer handles the full stack without handoffs.
DefTech Platform In Development
Building a platform that unifies cyber and physical threat monitoring, analysis, and response. The next frontier of Security × AI.
Free Diagnosis
Ask one security question. Free.

About
Green Tea LLC runs on one human, specialist networks, and countless AI agents. We build systems and service flows that scale without unnecessary headcount.
Former Nomura Research Institute consultant. Started in offensive security (GWAPT certified), built depth in machine learning — supervised, unsupervised, causal inference — and arrived at generative AI through that progression, not as a pivot to it. Now extending that stack toward the convergence of cyber and physical threat response.
