Vulnerability Reporting Policy

At Sendible, trust is our #1 value and we take the protection of our customers’ data very seriously.

The Sendible security team acknowledges the valuable role that independent security researchers play in internet security. As a result, we encourage responsible reporting of any vulnerabilities that may be found on our site or applications. Sendible is committed to working with security researchers to verify and address any potential vulnerabilities that are reported to us. As a policy, Sendible does not offer compensation for reported issues.

Please review these terms before you test and/or report a vulnerability. Sendible pledges not to initiate legal action against researchers for penetrating or attempting to penetrate our systems as long as they adhere to this policy.


Testing for security vulnerabilities:

Whenever a test or trial account is available, please conduct all vulnerability testing against such instances. Always use test or trial accounts when testing our online services.
