How to Block Mobile App Permission to External Messaging Apps

Appdome is a no-code mobile app security platform designed to add security features in mobile apps.

Appdome’s no-code mobile app security platform offers mobile developers, DevSec and security professionals a convenient and reliable way to protect Android and iOS apps without coding. When a user clicks “Build My App”, Appdome leverages a microservice architecture filled with 1000s of security plugins, and an adaptive code generation engine that matches the correct required plugins to the development environment, frameworks, and methods in each app.

Using Appdome, there are no development or coding prerequisites to build secured apps. There is no SDK and no library to manually code or implement in the app. The Appdome technology adds the relevant standards, frameworks, stores, and logic to the app automatically, with no manual development work at all.

Block mobile app permission to external messaging apps is part of Mobile Permission Control which can be found in the Appdome Mobility Suite under the Management tab.

When you Add Ability to Use In-App Messages Only to Mobile Apps, the app can not display alternate messaging apps when contact is clicked within the app. For more information on these types of controls, check out this blog.
