Isn't it some sort of security app pre-installed on Samsung phones?

As belodion said, it's preloaded on Samsung devices as a security app. It can be used if you use a work phone to separate work stuff from private stuff..
Nothing to worry about here

Here is a little bit more information. Yes it is built in security and it comes pre-installed on Samsung phones now. I think it probably came pre-installed on the S4, but if it didn't, it would have been added in an update.

This also will tell Samsung if you have rooted a phone. You might hear people talk about "tripping Knox" in regards to rooting. If you root and trip Knox (some rooting methods on some Samsung phones, do not trip Knox) then that also voids your phone warranty.

Here is some info about Knox:


If someone roots a phone and doesn't trip Knox, then unroot the phone when they send it in, Samsung won't know it is rooted before.

A Knox Counter of 0x1 means it has been tripped once.
