Security > NHN AppGuard > Console Guide

NHN AppGuard is provided in two versions: Android and iOS.

For Android users, NHN AppGuard is applied when apk files built on SDK integration (optional) go through application protection process (required) on a web console or command line interface(CLI). For iOS users, it is applied when the application files are created with SDK integration (required) and no further protection process is required.

Following diagram shows the NHN AppGuard application process.
