  • White-hat hacker’s vulnerability scanning was too costly for many companies.
  • Reports generated by foreign tools needed translation into Japanese.
  • Service release was delayed due to lack of security vendor resources.


  • Compared to other tools, Vex stands out for its minimal detection of false positives. The company no longer has to spend a lot of time and money verifying scan results.
  • Vex, a domestic tool, has good usability in view of the UI design familiar to the Japanese so it has succeeded in reducing the workload of engineers.
  • The company enabled clients to perform a certain level of scanning on their own, rather than relying solely on security vendors, thus strengthening their security management system.
