Zoom Contact Center admins can block consumers from sharing sensitive information in a web chat, in-app chat, or SMS engagement. You can block information by configuring regular expressions to detect certain strings or numbers. 

When consumers attempt to send a chat message that contains sensitive information, they will be notified with an automated message stating that their message couldn't be sent because it contains sensitive information. The assigned agent will also see this notification.

Notes:

• This feature blocks sensitive information in the actual chat conversation. You also mask consumers' information that's visible to agents.
• Learn more about controls that can minimize capture of payment card information.
