We use a combination of OpenDNS Umbrella and Threatstop as well as some internal filtering to accomplish this.

We don’t block URLs but we do manually dns sinkhole some domain names and send them to an information/warning page so 
we can track who clicks the links.

Subject: [SECURITY] Blocking phishing URL's

Greetings!

I’ve been asked to investigate what other institutions are doing to block access to URL’s at the edge (i.e. block 
connections when people click on a URL, despite virtual hosting or fastflux DNS).

Feel free to respond privately.  Thanks.

Best,
Cathy
