Please follow the details below if you require trusting specific parts of the Ziflow platform:

  1. Allowing Ziflow platform in your network/VPN

  2. Allowing Ziflow emails to make sure they're not landing in the SPAM folder

  3. Allowing Ziflow if you're reviewing staging websites


Allow the entire Ziflow platform

If reviewers are unable to see proofs or comments, you need to allow HTTPS and WSS traffic through for the following domains:

NOTE: Web sockets are specifically used for the *.ziflow.io domain to communicate with the proof and send updates.


Allow Ziflow emails

Ziflow sends system and notification emails to inform users and reviewers of new proofs to review and when the activity occurred on a proof. If you don't receive these email notifications from Ziflow, you can adjust your spam filter settings and allow our domain and IP addresses.

Work with your IT team to make changes to your allowlist or "safe sender" list. The following is a list of our email server IP addresses and domain:
