Cloud Security FAQ – Cloud Platform Console Help

If you plan to evaluate the security of your Cloud Platform infrastructure with penetration testing, you are not required to contact us.  You will have to abide by the Cloud Platform Acceptable Use Policy and Terms of Service, and ensure that your tests only affect your projects (and not other customers’ applications).  If a vulnerability is found, please report it via the Vulnerability Reward Program.
