How to Collect ThreatScore™ in Mobile Apps Using AI
This Knowledge Base article describes how to use Appdome’s AI in your CI/CD pipeline to continuously deliver plugins that Use ThreatScore Data in Mobile apps.
What is ThreatScore?
ThreatScore is an optional configuration in Mobile Device & Connection Risk that adds a numeric risk score to each user and device session, helping backend systems quantify and respond to bot and automation threats. This score reflects the cumulative risk based on detected mobile threats—such as root, Magisk, emulators, or fake location—and provides a simplified value to inform automated policy decisions.
How Appdome Adds ThreatScore to Mobile Apps
Appdome’s dynamic Get ThreatScore™ plugin for Android and iOS apps calculates a numeric risk score in real time based on selected on-device detections and session risk factors. The ThreatScore™ is embedded into each app’s network payload, allowing backend systems and WAFs to quickly assess and enforce policies against high-risk sessions. The feature works automatically at runtime and requires no code, SDKs, or backend changes, making it easy to deliver advanced bot risk scoring as part of CI/CD pipelines.
Prerequisites for Using Appdome's Get ThreatScore™ Data Plugins:
To use Appdome’s mobile app security build system to Use ThreatScore Data , you’ll need:
- Appdome account (create a free Appdome account here)
- A license for Get ThreatScore™ Data
- Mobile App (.ipa for iOS, or .apk or .aab for Android)
- Signing Credentials (see Signing Secure Android apps and Signing Secure iOS apps)
How to Implement Use ThreatScore Data in Mobile Apps Using Appdome
On Appdome, follow these 3 simple steps to create self-defending Mobile Apps that Use ThreatScore Data without an SDK or gateway:
-
Designate the Mobile App to be protected.
-
Upload an app via the Appdome Mobile Defense platform GUI or via Appdome’s DEV-API or CI/CD Plugins.
-
Mobile App Formats: .ipa for iOS, or .apk or .aab for Android
-
Get ThreatScore™ Data is compatible with: Obj-C, Java, JS, C#, C++, Swift, Kotlin, Flutter, React Native, Unity, Xamarin, and more.
-
-
Select the defense: Get ThreatScore™ Data.
-
-
Follow the steps in Sections 2.2-2.2.2 of this article to add the Get ThreatScore™ Data feature to your Fusion Set via the Appdome Console.
-
When you enable Session Risk you'll notice that the Fusion Set you created in step 2.1 now bears the icon of the protection category that contains Get ThreatScore™ Data.
Figure 2: Fusion Set that displays the newly added Get ThreatScore™ Data protection
Note: Annotating the Fusion Set to identify the protection(s) selected is optional only (not mandatory). -
Open the Fusion Set Detail Summary by clicking the “...” symbol on the far-right corner of the Fusion Set. Copy the Fusion Set ID from the Fusion Set Detail Summary (as shown below):
Figure 3: Fusion Set Detail Summary
-
Follow the instructions below to use the Fusion Set ID inside any standard mobile DevOps or CI/CD toolkit like Bitrise, Jenkins, Travis, Team City, Circle CI or other system:
-
Refer to the Appdome API Reference Guide for API building instructions.
-
Look for sample APIs in Appdome’s GitHub Repository.
-
Create and name the Fusion Set (security template) that will contain the Get ThreatScore™ Data feature as shown below:
Figure 1: Fusion Set that will contain the Get ThreatScore™ Data feature
-
-
Add the Get ThreatScore™ Data feature to your security template.
-
Navigate to Build > Anti Bot tab > MobileBOT™ Defense section in the Appdome Console.
-
Toggle On Session Risk > Get ThreatScore™ Data.

-
Congratulations! The Get ThreatScore™ Data protection is now added to the mobile app -
-
Certify the Get ThreatScore™ Data feature in Mobile Apps
After building Get ThreatScore™ Data, Appdome generates a Certified Secure™ certificate to guarantee that the Get ThreatScore™ Data protection has been added and is protecting the app. To verify that the Get ThreatScore™ Data protection has been added to the mobile app, locate the protection in the Certified Secure™ certificate as shown below:
Figure 5: Certified Secure™ certificate
Each Certified Secure™ certificate provides DevOps and DevSecOps organizations the entire workflow summary, audit trail of each build, and proof of protection that Get ThreatScore™ Data has been added to each Mobile app. Certified Secure provides instant and in-line DevSecOps compliance certification that Get ThreatScore™ Data and other mobile app security features are in each build of the mobile app.
Using Threat-Events™ for ThreatScore Data Intelligence and Control in Mobile Apps
Appdome Threat-Events™ provides consumable in-app mobile app attack intelligence and defense control when ThreatScore Data is detected. To consume and use Threat-Events™ for ThreatScore Data in Mobile Apps, use AddObserverForName in Notification Center, and the code samples for Threat-Events™ for ThreatScore Data shown below.
The specifications and options for Threat-Events™ for ThreatScore Data are:
| Threat-Event™ Elements | Use ThreatScore Data Method Detail |
|---|---|
| Appdome Feature Name | Get ThreatScore™ Data |
| Threat-Event Mode | |
| OFF, IN-APP DEFENSE | Appdome detects, defends and notifies user (standard OS dialog) using customizable messaging. |
| ON, IN-APP DETECTION | Appdome detects the attack or threat and passes the event in a standard format to the app for processing (app chooses how and when to enforce). |
| ON, IN-APP DEFENSE | Uses Appdome Enforce mode for any attack or threat and passes the event in a standard format to the app for processing (gather intel on attacks and threats without losing any protection). |

The following is a code sample for native Mobile apps, which uses all values in the specification above for Get ThreatScore™ Data:
Important! Replace all placeholder instances of <Context Key> with the specific name of your threat event context key across all language examples. This is crucial to ensure your code functions correctly with the intended event data. For example, The <Context Key> could be the message, externalID, OS Version, reason code, etc.

There is no SDK and no library to code or implement in the app and no gateway to deploy in your network. All protections are built into each app and the resulting app is self-defending and self-protecting.
Releasing and Publishing Mobile Apps with Get ThreatScore™ Data
After successfully securing your app by using Appdome, there are several available options to complete your project, depending on your app lifecycle or workflow. These include:
- Customizing, Configuring & Branding Secure Mobile Apps.
- Deploying/Publishing Secure mobile apps to Public or Private app stores.
- Releasing Secured Android & iOS Apps built on Appdome.
