This probably wipes out 90% of all classes of vulnerabilities that can be exploited on a device. Its crazy engineering. No other phones on earth have this protection.
Android phones have something called MTE that is a basic version of this, but due to performance issues, isnt really feasible to have enabled all the time unlike MIE.
