We take the security of our systems seriously, and we also value the developer community. Our responsible disclosure policy promotes the discovery and reporting of security vulnerabilities to help us ensure the security and privacy of our users. If you’re a security researcher, please follow the guidelines and steps below to report vulnerabilities.


We require all security researchers to:

  • Avoid privacy violations, degradation of user experience, disruption to production systems, and destruction of data during security testing;
  • Perform research only within the scope set out below;
  • Use the identified communication channels to report vulnerability information to us; and
  • Keep information about any vulnerabilities you’ve discovered confidential between yourself and Cloud2Voice until we’ve had 90 days to resolve the issue.

If you follow these guidelines when reporting an issue to us, we will commit to:

  • Not pursue or support any legal action related to your research;
  • Work with you to understand and resolve the issue quickly (including an initial confirmation within 72 hours of submission that your report has been received);
  • Recognize your contribution on our Security Researcher Hall of Fame, if you are the first to report the issue and we make a code or configuration change based on the issue;
  • Award you Cloud2Voice credits that you can use however you like.
