No. Unlike other mail protection solutions, you don’t need to change your DNS records or make other public, disruptive changes to protect yourself with INKY Phish Fence. We use the latest Microsoft technologies to vastly simplify setup and deployment; most customers are up and running in under an hour. And unlike other solutions, INKY Phish Fence supports a staged roll-out to groups of users at a time, rather than requiring a single “big bang” cut-over.
