Vulnerability Disclosure Program


To protect businesses and organizations worldwide, it is critical that the broader community of IT and security professionals report potential vulnerabilities as soon as they are recognized. This allows industry experts to take appropriate action to resolve any vulnerability that is discovered. If you are aware of a potential security vulnerability with any Zip product or service, we encourage you to contact us immediately at cybersecurity@zip.co. All reported vulnerabilities are investigated by the Zip Cybersecurity team. Throughout the investigation process, Zip Security makes every effort to work collaboratively with the incident reporter to investigate the vulnerability, gather required technical information, and to determine an appropriate action plan.

A security vulnerability is a flaw or weakness in the design, implementation, operation or management or a product or service that could be exploited to compromise the confidentiality, integrity, or availability of data.
