We actively block a large list of domains that are primarily focused on financial websites but not limited to only financial websites. Any URL that includes "bank" will be blocked.
While we don't keep this article up to date with every host that we pro-actively block below is a relatively recent list of domains.
It's rare for us to unblock these for users however if you have an excellent use case we'll review your request.
We also actively resolve each of these hosts from 140+ countries and block their corresponding IP addresses in case the domain has GEO DNS resolving.
In addition to blocking specific domains below we also pro-actively block access to .gov websites.
