If you have questions about the security of your Zendesk instance, contact Zendesk directly. In case of a suspected security breach, submit a ticket with the subject “Security” along with the details. Alternatively, you can send an email to security@zendesk.com.
Important: Zendesk will never contact you by submitting a ticket to your account. If Zendesk needs to contact you, we'll use direct administrator email addresses, and it will always come from a @zendesk.com or @support.zendesk.com domain. Preventing spam General guidelines
