I think Square Enix should look into possibly using Easy Anti Cheat for XIV

[KageTokage]

No security program is a proper replacement for a functional enforcement team (Which XIV is sorely lacking in, at least when it comes to cheaters who aren't painfully obvious).

The games I have played with anti-cheat programs were annoying as simply alt-tabbing out of the game was a potential trigger to make it shut down the client and people found ways to get around said programs regardless.

anti cheat software are often inadequate in doing anything. Those software often break the games they're supposed to protect. They mostly only affect legitimate users.

Anti cheat program would also have the side effect of probably preventing people who use Linux from playing FF14.
While Linux is an unsupported platform it is possible to play the game on it right now. (And pretty well at that)
It would be sad for those people to lose the ability to play the game they pay for in exchange for a program that doesn't really work.

Just my opinion ^^
