signageOS Bug Bounty Program Policy

For Professional Security Researchers

Bug Bounty Policy

Software security researchers are increasingly engaging with Internet companies to hunt down vulnerabilities. signageOS works with security experts across the globe to stay up-to-date with the latest security techniques. If you've discovered a security issue that you believe we should know about, we'd love to work with you. Our bug bounty program provides a monetary reward for these efforts.

The signageOS's Bug Bounty Program applies to security vulnerabilities found within signageOS's public-facing online environment. This includes, but is not limited to, signageOS's websites, exposed APIs, mobile applications, and devices. For the protection of our customers, we do not disclose, discuss or confirm security matters until comprehensively investigating, diagnosing and fixing any known issues.

How to Participate

Highly skilled security researchers can participate in signageOS's Bug Bounty Program.

To submit a Bug Report, fill in this form: Bug Bounty Report Form.

You may be eligible to receive a monetary reward if:

  • That vulnerability is determined to be a valid security issue by signageOS's security team
  • You have complied with all Program Terms

All bounty amounts will be determined at the discretion of the "signageOS s.r.o" Bug Bounty team who will evaluate each report for severity, impact, and quality. Rewards amounts vary depending upon the severity of the vulnerability reported. There could be submissions that we determine have an acceptable level of risk such that we do not make changes.

The minimum bounty amount for a validated bug submission is $50 USD and the maximum bounty for a validated bug submission is $5.000 USD. signageOS's Bug Bounty team retains the right to determine if the bug submitted to the Bug Bounty Program is eligible. All determinations as to the amount of a bounty made by the signageOS Bug Bounty team are final.

Type of Bug Reported Reward Range
Level 0 - Informational $ 0 - $ 0
Level 1 - Low $ 50 - $ 150
Level 2 - Medium $ 150 - $ 450
Level 3 - High $ 500 - $ 3.000
Level 4 - Critical $ 1.500 - $ 5.000
