Vex challenged Cybozu's security project, the Cybozu Bug Bounty Program, and received high marks for uncovering several vulnerabilities. This led to the decision to adopt Vex.

Cybozu focuses on cloud-based groupware and business improvement applications to support "teams delivering results" around the world. A diverse range of teams are currently using the products and services, from small projects such as students, NPOs, and home healthcare group to large corporations with global offices. In addition, the company launched the Cybozu Corporation CSIRT (abbreviated Cy-SIRT) to engage in the prevention of incidents, early detection, early resolution, and minimization of damage in cooperation with external organizations and experts. The assurance group of Quality Assurance Department Global Development Division organized a meeting body that examines all IT security policies within the organization. The group also supports the Cy-SIRT operation and manages the bug bounty programs.
