Cloudstaff Bug Bounty

Cloudstaff Bug Bounty fosters collaboration amongst security professionals to help protect our customers’ personal information from malicious activity due to vulnerabilities against our networks, web and mobile applications and set security policies across our organization.

We treat the security and safety of our customers’ personal information with the utmost importance. For the protection of our customers, Cloudstaff does not disclose, discuss or confirm security matters until comprehensively investigating, diagnosing and fixing any known issues.

  • Do not intentionally harm the experience or usefulness of the service to others, including the degradation of services & denial of service attacks.
  • Do not attempt to view, modify, or damage data belonging to others
