Blocking policy can be set for tampering trials of code, memory or speed, while NHN AppGuard is running, and blocking conditions can set for 'Block by Condition' based on threshold.


When it is detected by policy set as Block All, guide for NHN AppGuard shows and the app is closed. When the conditions set in Block by Condition are met, the user is blacklisted, and if the user launches the app, the NHN AppGuard guide window appears and the app is ended.

For further details on the policy, please refer to "NHN AppGuard Developer's Guide" document included in the SDK.

Introduction to Block Features

  • NHN AppGuard > Policy > Block All
    • If set to Block Allin the NHN AppGuard Policy screen, the app will be ended as soon as the behavior is detected.
    • Even if the app is shut down due to a policy, you can use the app normally if you relaunch the app without any abnormal behavior.
    • If you change the policy to Block All or Detect, it will be applied to the app that has restarted after about a minute.
  • NHN AppGuard > Policy > Block by Condition
    • If you set it to Block by Conditionon the NHN AppGuard policy screen, it will blacklist users who meet the condition at 00:00 every day.
    • Whether the conditions are met is determined based on detection logs that occurred between 00:00:00 and 23:59:59 in the last day, and each condition works independently by type.
    • You can check the blacklist registered as conditional blocking on the NHN AppGuard Blacklist tab.
    • Users blocked due to blacklisting registered as conditional blocking are not exposed to the NHN AppGuard dashboard tab.
    • Users blacklisted with conditional blocking will not be able to use the app for the block period you set, even if they launch the app without any abnormal behavior.
    • If you change a setting or condition with conditional blocking, it will take effect for all users after about 10 minutes.
  • Block through NHN AppGuard > Blacklist
    • If you blacklist a user on the NHN AppGuard Blacklist screen and the user launches an app, the app will be ended.
    • It takes effect when the app is re-launched, starting immediately after blacklisting.
