Frequently Asked Questions

How do I allow Webex traffic?

If the client connects to Webex via the destination port that is received from the server, Webex will communicate with the server on that port. In order for these return connections to be allowed through a firewall, the firewall should be configured appropriately. A route-able IPv4 path must be established between the connecting device and the device with HTTPS encryption between the devices.

Is Webex traffic encrypted?

The transmission of data is encrypted, as well as the storage of data at rest. Before sending any of the user-generated content (such as messages, files, and whiteboards) over the TLS protocol, Webex App encrypts all of it. This encrypted content is stored in the Webex cloud on encrypted content servers, which are also hosted in the Webex cloud.
