How to Collect Threat-Event™ Meta-Data in Mobile Apps Using AI

Last updated August 7, 2025 by Appdome

This Knowledge Base article describes how to use Appdome’s AI in your CI/CD pipeline to continuously deliver plugins that Use Threat-Event Meta-Data in Mobile apps.

What is Threat-Event Meta-Data?

Threat-Event™ Meta-Data is an optional configuration in Mobile Device & Connection Risk that enriches mobile bot detection payloads with additional environmental context, including operating system, device model, manufacturer, and SSL certificate metadata. These metadata fields are used by WAFs to assess whether the mobile session originates from a legitimate safe or at risk endpoint. For example, a mismatch between the expected OS and actual manufacturer may indicate spoofing, emulation, or device tampering. Including Threat-Event™ Meta-Data enhances precision in bot detection by providing critical details needed to analyze and respond to suspicious sessions. This is especially useful in regulated industries like fintech or healthcare, where understanding device provenance and environment is key to securing app workflows, detecting anomalies, and enforcing zero-trust access controls.

How Appdome Adds Threat-Event™ Meta-Data to Mobile Apps

Appdome’s dynamic Threat-Event™ Meta-Data plugin for Android and iOS apps appends details including operating system, device name, and manufacturer to MobileBOT™ Defense session payloads. These securely embedded metadata fields are embedded into each connection request, giving backend systems the data needed to analyze the device’s context and make policy decisions. Developers can enable this option in CI/CD with no SDKs or server changes to improve visibility across mobile sessions and support advanced session analytics and WAF enforcement.

Prerequisites for Using Appdome's Threat-Event™ Meta-Data Plugins:

To use Appdome’s mobile app security build system to Use Threat-Event Meta-Data , you’ll need:

How to Implement Use Threat-Event Meta-Data in Mobile Apps Using Appdome

On Appdome, follow these 3 simple steps to create self-defending Mobile Apps that Use Threat-Event Meta-Data without an SDK or gateway:

  1. Designate the Mobile App to be protected.

    1. Upload an app via the Appdome Mobile Defense platform GUI or via Appdome’s DEV-API or CI/CD Plugins.

    2. Mobile App Formats: .ipa for iOS, or .apk or .aab for Android
    3. Threat-Event™ Meta-Data is compatible with: Obj-C, Java, JS, C#, C++, Swift, Kotlin, Flutter, React Native, Unity, Xamarin, and more.
  2. Select the defense: Threat-Event™ Meta-Data.

      1. Create and name the Fusion Set (security template) that will contain the Threat-Event™ Meta-Data feature as shown below:
        fusion set that contains Threat-Event™ Meta-Data

        Figure 1: Fusion Set that will contain the Threat-Event™ Meta-Data feature

      2. Follow the steps in Sections 2.2-2.2.2 of this article to add the Threat-Event™ Meta-Data feature to your Fusion Set via the Appdome Console.

      3. 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 Threat-Event™ Meta-Data.

        Fusion Set applied Threat-Event™ Meta-Data

        Figure 2: Fusion Set that displays the newly added Threat-Event™ Meta-Data protection
        Note: Annotating the Fusion Set to identify the protection(s) selected is optional only (not mandatory).

      4. 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): fusion Set Detail Summary image

        Figure 3: Fusion Set Detail Summary

      5. 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:
        1. Refer to the Appdome API Reference Guide for API building instructions.
        2. Look for sample APIs in Appdome’s GitHub Repository.
    1. Add the Threat-Event™ Meta-Data feature to your security template.

      1. Navigate to Build > Anti Bot tab > MobileBOT™ Defense section in the Appdome Console.
      2. Toggle On Session Risk > Threat-Event™ Meta-Data.
        Threat-Event™ Meta-Data option

        Figure 4: Selecting Use Threat-Event Meta-Data

    2. Initiate the build command either by clicking Build My App at the bottom of the Build Workflow (shown in Figure 4) or via your CI/CD as described in Section 2.1.4.
    Congratulations!  The Threat-Event™ Meta-Data protection is now added to the mobile app
  3. Certify the Threat-Event™ Meta-Data feature in Mobile Apps

    After building Threat-Event™ Meta-Data, Appdome generates a Certified Secure™ certificate to guarantee that the Threat-Event™ Meta-Data protection has been added and is protecting the app. To verify that the Threat-Event™ Meta-Data protection has been added to the mobile app, locate the protection in the Certified Secure™ certificate as shown below: Threat-Event™ Meta-Data shown in Certificate secure

    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 Threat-Event™ Meta-Data has been added to each Mobile app. Certified Secure provides instant and in-line DevSecOps compliance certification that Threat-Event™ Meta-Data and other mobile app security features are in each build of the mobile app.

Using Threat-Events™ for Threat-Event Meta-Data Intelligence and Control in Mobile Apps

Appdome Threat-Events™ provides consumable in-app mobile app attack intelligence and defense control when Threat-Event Meta-Data is detected. To consume and use Threat-Events™ for Threat-Event Meta-Data in Mobile Apps, use AddObserverForName in Notification Center, and the code samples for Threat-Events™ for Threat-Event Meta-Data shown below.

The specifications and options for Threat-Events™ for Threat-Event Meta-Data are:

Threat-Event™ Elements Use Threat-Event Meta-Data Method Detail
Appdome Feature Name Threat-Event™ Meta-Data
Threat-Event Mode

The following is a code sample for native Mobile apps, which uses all values in the specification above for Threat-Event™ Meta-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.



Using Appdome, there are no development or coding prerequisites to build secured Mobile Apps by using Threat-Event™ Meta-Data. 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.

Device Binding in the Age of AI

For years, fraud prevention solutions have tried to use Device IDs to bind (or link) a user’s account or session to a specific device to prevent unauthorized access from other devices. However, until recently, Device IDs lacked persistence and the broad threat context needed to stop fraud and ATOs …
