How to Create and Manage Appdome Mobile App Protection Templates for Android & iOS Apps

Last updated September 27, 2023 by Appdome

Appdome users can create mobile app security templates, known as Fusion Sets, to speed up and repeat mobile app security projects. Fusion Sets can include validated, approved, required or known combinations of features, services, and configurations for your app. You can reuse Fusion Sets across different builds and releases, or share them with different teams, or subscribe Fusion Sets to multiple mobile apps at one time.

This Knowledge Base article provides step-by-step instructions on how to create, use, and manage Fusion Sets in Android and iOS apps.

Appdome is a mobile application Cyber Defense Automation platform to add security protections to mobile apps. When a user clicks Build My App or builds an app via CI/CD, Appdome leverages a microservice architecture of 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 Android and iOS apps. There is no SDK or library to manually code or implement in the app. The Appdome technology adds the relevant standards, frameworks, and logic to the app automatically, with no manual development work at all.

What are Appdome Fusion Sets?

Fusion Sets are pre-built, reusable, sharable mobile app security templates that contain all the selected security features, settings, options, and configurations that Appdome builds into your iOS and Android apps whenever you build your app. Fusion Sets accelerate and automate mobile security implementations, ensure implementation consistency, and reduce integration time for each build or release of your mobile apps.

Prerequisites for using Appdome Fusion Sets

In order to use Appdome Fusion Sets features, you will need:

Default Playground Fusion Set

A default Playground Fusion Set is created for each app whenever you upload a mobile app to Appdome. The Playground Fusion Set cannot be released to Team Workspaces and, therefore, cannot be shared between apps in your workspace and will only affect the app for which it was created. In addition, unlike all other Fusion Sets, the Playground Fusion Set cannot have a versioning history and cannot be modified in any of the following ways:

Nevertheless, it is possible to duplicate the Playground Fusion Set, with all its settings, by clicking the Copy icon as shown below.

How to Create and Use Fusion Sets for Android and iOS Apps 

You can either use the default Playground Fusion Set or Create a new Fusion Set.

Creating a New Fusion Set

As a best practice, you are strongly advised to create a new blank fusion set and populate it with different security features.

To create a new Fusion Set:

  1. Open the Fusion Set drop-down list by clicking the arrow icon on the right.
    Fs My App 2
  2. Click Create New Fusion Set to create a new blank Fusion Set.
    Fs Create My App 5
  3. Enter a name in the text box.
    Fs My App 2
  4. Click Save.
    Note: You must assign a unique name, as there cannot be two Fusion Sets that have the same name.

Reviewing the Fusion Set List

The Fusion Sets list allows viewing at a glance multiple details about each of the Fusion Sets.

The selected Fusion Set is indicated by the green checkmark on the left.

To view and edit details about a specific Fusion Set:

  1. Select the requested Fusion Set by clicking the check box on the left.
  2. Click the Details button on the right.
    My Fs 7
  3. Use the Fusion Set Details tab to change one or more details about the selected Fusion Set.
    fs details
  4. Click the icon to the right of the Fusion Set Name field to rename the Fusion Set, and click Save when done.

Clicking a Fusion Set name allows renaming the Fusion Set, as seen below.


The Services section in each row allows viewing the services assigned to each Fusion Set.

The Fusion Set row displayed the time and date when the last modification took place. If the Fusion Set was imported, the row displays from which team it was imported.


Modified Fusion Sets

The Fusion Set row can also be used for performing the following operations:

  • Copying (duplicating) an existing Fusion Set by clicking Copy.
    Fs Copy
  • Subscribing all Android/iOS apps to the selected template (Fusion Set).
    Subscribe Fs
  • Deleting the Fusion Set (if the Fusion Set is frozen, you should unfreeze it prior to deleting).
    Fs Delete
    Deleting a Fusion Set affects all apps that are subscribed to the Fusion Set at the time of the deletion. After the deletion operation is confirmed, all subscribed apps will revert to be subscribed to the Playground Fusion Set.

You can now add to your mobile security template by adding features and services to the Fusion Set and creating custom implementations to suit specific use cases. You can also subscribe to new apps or remove apps from this Fusion Set to complete multiple projects in parallel.

Reviewing the Fusion Set Details

You can review the Fusion Set details by clicking the Details button.
Details button
The Details dialog box opens now.

Saving and Annotating a Fusion Set

On the platform footer near the Build my App and Annotate Changes buttons, you can see the data when your fusion set was modified last time and by whom. When you perform one or more modifications in the Fusion Set, the button Annotate Changes becomes enabled at the bottom of the screen.

The annotation is meant to provide Appdome users with enhanced transparency and control over their security services selections.
The time and date of the modification are visible below the annotation, and you need to use the annotation field to specify what the modification was and what were the reasons for the modification.

Toggle Annotate Changes

To annotate a fusion set:

  1. Click Annotate Changes.
    The dialog box Add Fusion Set Annotation opens.
    add fusion set annotaition
  2. Set Fusion Set version, including numbers and dots (optional).
    Enter the requested text for the annotation (up to 250 characters).
    Ensure that you enter meaningful, helpful text, ideally with the following information:
    Meaningful description; for example, the purpose of the modification, the targeted group (QA, development, and so on), and the month of the release.
    Fusion Set Annotaiton applied
  3. Click Save.
    Now your Fusion Set is saved and annotated.
    When you produce a Certified Secure certificate, the certificate displays the annotation.
    Certificate My AppCert With Annotation V1

If you do not click the Annotate Changes button but instead click Build My App, an annotation will automatically be added.
Automatic annotations also will be added when the following operations take place:

  • Building (when there are changes in the Fusion Set)
  • Freezing an Appdome Version
  • Unfreezing an Appdome Version
  • Unfreezing a Fusion Set
  • Session Time Out
  • Selecting to save signing credentials when prompted to
  • Renaming a Fusion Set
  • Adding OS Coverage
