Vulnerability Disclosure Program


At Sonder, one of our founding principles is to “Improve Continuously” which directly translates into our information security program enabling the protection of our guests and customer data as a top priority.

The Sonder Security Team acknowledges the valuable role that honest, independent security researchers and bug reporters play in the overall security of connected systems. As a result, we encourage the responsible reporting of any vulnerability that may be present in our guest properties, mobile application, or company website and services. Sonder is committed to working with security researchers to verify and address potential vulnerabilities that are reported to us.

Please review these terms before you test and/or report a vulnerability to Sonder. We will provide a safe harbor to security researchers as long as they adhere to this policy and are acting in good faith.
