How to Freeze-Lock Moible App Protection Templates for Android & iOS RCs in DevSecOps Build System

Last updated August 10, 2021 by Appdome

Learn how DevSecOps teams use Appdome’s Freeze Fusion Set feature to lock-in an approved set of security features for iOS and Android apps, which can be optionally tied to a specific Appdome version. This enables organizations to build and secure apps at DevSecOps speed, while simultaneously ensuring continuity and change control standards are met.

What is the Appdome Freeze Fusion Set Feature?

Appdome’s Freeze Fusion Set feature allows customers to lock (or ‘freeze’) the Fusion Set configuration/settings (ie: the security features included in your app) and/or the Appdome version associated with a mobile application secured using Appdome.

How Does Appdome’s Freeze Fusion Set Feature Work?

This Knowledge Base article covers how to use Appdome’s Freeze Fusion Set feature in order to “lock-in” a consistent security model comprised of their required security features, and standardize on a known Appdome build/release, as part of their change and version control practices.

For Appdome licensed customers, there are several options for using the Freeze Fusion Set feature:

  • Freeze Fusion Set – This option freezes the security features that will be built into the mobile application
  • Freeze Appdome Version  – This option freezes the Appdome version. (This option is licensed separately).
  • Freeze Fusion Set and Appdome Version – This option freezes both the security features as well as the Appdome version
