So what is protected DNS? Basically, it's a security technology that relies on taking a look at DNS traffic, and what this lets you do is to see where people are going, and lets you deflect them from going to bad places. You can detect outbound attacks in other words.

Sometimes people in your organization will get infected with a virus and they'll start participating in DDoS attacks or whatever you can detect that, and it lets you take the appropriate action.

So it's a technology for doing that and what it does is it rejects web pages and emails, and so forth that it knows are harmful before they even enter your network. So that's a big plus, DNS protective. 

DNS is a mandate by several governments in order to adhere to compliance issues like ITAR or just to keep your site safe. So Australia, Canada, Italy, they're all examples of countries that have mandated a certain amount of Protective DNS.

There's other DNS protection things like DNSSEC. We're not going to talk about them today, but you understand that it's part of it, and there's other people who claim that PDNS is an acronym for something else. You got to deal with that.
