ATP is already in use by a few early adopters right now, and it'll be more broadly available later in 2016. You probably won't see how this works unless you're managing a network, but it could make a big difference in your life if you've ever been notified of a compromised bank account or health care file. Instead of waiting months for the company to even realize that there was a problem (long after fraudsters have a field day), you could get a heads-up much sooner. That, in turn, could speed up the fix and reduce the chances that someone raids your sensitive info.
