Tenchi Security

Tenchi Security builds Zanshin, a Third-Party Cyber Risk Management platform that targets a specific and persistent attack surface: your vendors' cloud infrastructure. The product combines external attack surface monitoring with automated, non-intrusive assessments of security controls across IaaS, PaaS, and SaaS environments. The threat model is direct - third and Nth parties represent an expanding, poorly understood perimeter, and Zanshin attempts to map it systematically. The technical stack operates across cloud security , attack surface monitoring , and risk assessment domains, linking outside-in visibility with inside-out data collection. The goal is continuous monitoring rather than point-in-time questionnaires, which means the engineering challenges involve scalable scanning, data correlation, and control validation across diverse cloud architectures. The platform serves industries where supply chain compromise carries material consequences: banking , enterprise , and broader supply chain security . The team includes security veterans from Apple, Google, and Verizon, bringing over 25 years of combined experience in the space. Tenchi Security is building for a problem that scales with every new SaaS dependency and cloud integration - an attack surface most organizations still measure with spreadsheets and annual attestations.
