TrustONE Security Inc. is a cybersecurity software company with self-developed technology and its own brand in Taiwan, and is an affiliate invested by the listed company Zero One Technology Co., Ltd. The TrustONE Zero Trust Stealth Joint Defense Solution provides "Zero Trust Security Proxy" and "Stealth Zone Defense" mechanisms. Based on the technical concepts of "Zero Trust" and "Stealth", it adopts a proxy host architecture to perform two-factor authentication, establishing a stealth isolated protection zone outside the protected operational host. Inside the protected operational host, it utilizes proprietary stealth protection technology to hide and protect important local folders, providing anti-deletion and anti-writing security procedures through underlying protection mechanisms. By protecting operational hosts from both the inside and outside using two mechanisms—the security proxy host architecture and local protection—it protects the critical hosts of government agencies and enterprises through a two-pronged approach.

Numerous clients, including central government ministries, county and municipal governments, national research institutions, financial industries, and manufacturing industries, have already used TrustONE's "Zero Trust Stealth Joint Defense" product services to build and deepen core data security solutions.
