Is it possible to setup firewall rules in Tableau online to ban user by ip list? (only allow user access from ip whitelist)
The main concern behind this question is security issue, which means some of our users may pass their account/pwd to others. But we don't want those people who are not from specific ip range to access our dashboard and data.
Tableau Online is hosted by Tableau directly, so it isn't possible to add custom ip safelists as part of authentication. You can see user activity in the Admin views on Tableau Online, which will let you see when each user is accessing your Tableau Online site. You might also consider implementing SAML for your Tableau Online site.
