Every organization faces an existential threat from the third parties they rely on - vendors, suppliers, and partners that can introduce uncontrollable risks to their security posture. These third and Nth parties expand attack surfaces in ways that traditional risk management cannot address, leaving even the largest enterprises vulnerable to breaches they cannot directly control. Tenchi Security exists to eliminate this blind spot with Zanshin, the only global Third-Party Cyber Risk Management (TPCRM) solution that systematically reduces these risks rather than simply measuring and accepting them.
Zanshin combines inside-out and outside-in visibility, linking external attack surface monitoring with automated, continuous, and non-intrusive assessments of cloud infrastructure (IaaS, PaaS, SaaS) and security controls across entire business ecosystems. This cooperative, remediation-first approach enables first-parties to invest in improving the security of critical third-parties, transforming third-party risk from a compliance exercise into a shared responsibility that actually reduces vulnerabilities. Backed by investors including Accenture Ventures, Bradesco, and L4 Venture Builder, Tenchi's team of security veterans from Apple, Google, and Verizon brings 25+ years of experience to protect the supply chains of major banks and enterprises worldwide.
