Responsible Disclosure Policy

ResponsibleDisclosure.com (operated by an independent third party, Synack, on behalf of Amex GBT).

This page is for security researchers interested in reporting application security vulnerabilities. This is intended for application security vulnerabilities only.

The details within your request form will be submitted to Synack. If you have reported an issue determined to be within program scope and to be a valid security issue, Synack will validate your finding and you will be allowed to disclose the vulnerability after a fix has been issued. This process is managed exclusively by Synack through their platform, accordingly you must accept the Synack terms of service if you wish to proceed. All queries are to be directed to Synack and managed exclusively through the ResponsibleDisclosure.com online portal.
