Greg Kras, our Chief Success Officer replied with:
"In doing some surveying of customers and folks that have constant interaction with customers it seems that strategies vary between sites but there are a few commonalities that I can share:
Safe link and link re-writing services are certainly something that we’ve seen adoption of by customers but we have found that those often serve to confuse the end user as now everything “goes to the same place”.
I’m personally not a fan of reducing the already limited information a user can glean from an email, particularly since the link re-writing is typically executed a technical control that should have blocked/caught the message before getting in front of the user. I prefer URL inspection on egress if feasible.
Ultimately we always find that user education is the answer that transcends the technical controls, the more isolated the user is from making awareness driven decisions the more likely they are to be taken advantage of when the inevitable threat emerges.
