How To Protect Mobile Apps with Enforce Forward Secrecy using AI

Last updated July 5, 2026 by Appdome

This Knowledge Base article describes how to use Appdome’s AI in your CI/CD pipeline to continuously deliver plugins that Use Enforce Forward Secrecy in Mobile apps.

What is Enforce Forward Secrecy?

Perfect Forward Secrecy (PFS) is a TLS security mechanism that generates a unique encryption key for every TLS session. Because session keys are created independently of the server’s long-term private key, previously recorded communications remain protected even if the server’s private key is compromised in the future.

Enforce Forward Secrecy, part of Pin to Host Identity, requires TLS connections to use PFS-capable handshake algorithms when establishing secure sessions with trusted hosts. This helps ensure that every session is protected with unique encryption keys, reducing the risk of historical traffic being decrypted after a future key compromise.

How Appdome Protects Mobile Apps with Enforce Forward Secrecy?

Appdome’s Enforce Forward Secrecy capability validates that TLS connections negotiate Perfect Forward Secrecy (PFS) handshake algorithms before establishing secure communication with trusted hosts. Connections that do not support approved PFS algorithms are rejected, helping ensure that each TLS session uses independently generated session keys. Combined with Pin to Host Identity, this strengthens communication security while reducing the impact of future server key compromise.

Note: To use Enforce Forward Secrecy, the backend server must be configured to support PFS-compatible TLS cipher suites. If the server does not support these cipher suites, secure connections cannot be established.

Prerequisites for Using Appdome's Enforce Forward Secrecy Plugins:

To use Appdome’s mobile app security build system to Use Enforce Forward Secrecy , you’ll need:

How to Implement Use Enforce Forward Secrecy in Mobile Apps Using Appdome

On Appdome, follow these 3 simple steps to create self-defending Mobile Apps that Use Enforce Forward Secrecy 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. Enforce Forward Secrecy is compatible with: Obj-C, Java, JS, C#, C++, Swift, Kotlin, Flutter, React Native, Unity, Xamarin, and more.
  2. Select the defense: Enforce Forward Secrecy.

      1. Create and name the Fusion Set (security template) that will contain the Enforce Forward Secrecy feature as shown below:
        fusion set that contains Enforce Forward Secrecy

        Figure 1: Fusion Set that will contain the Enforce Forward Secrecy feature

      2. Follow the steps in Sections 2.2-2.2.2 of this article to add the Enforce Forward Secrecy feature to your Fusion Set via the Appdome Console.

      3. When you enable Pin to Host Identity you'll notice that the Fusion Set you created in step 2.1 now bears the icon of the protection category that contains Enforce Forward Secrecy.

        Figure 2: Fusion Set that displays the newly added Enforce Forward Secrecy 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 Enforce Forward Secrecy feature to your security template.

      1. Navigate to Build > API & Bot Protection tab > Trusted Application Identity section in the Appdome Console.
      2. Toggle On Pin to Host Identity > Enforce Forward Secrecy.
        Enforce Forward Secrecy option

        Figure 4: Selecting Use Enforce Forward Secrecy

    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 Enforce Forward Secrecy protection is now added to the mobile app
  3. Certify the Enforce Forward Secrecy feature in Mobile Apps

    After building Enforce Forward Secrecy, Appdome generates a Certified Secure™ certificate to guarantee that the Enforce Forward Secrecy protection has been added and is protecting the app. To verify that the Enforce Forward Secrecy protection has been added to the mobile app, locate the protection in the Certified Secure™ certificate as shown below: Enforce Forward Secrecy 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 Enforce Forward Secrecy has been added to each Mobile app. Certified Secure provides instant and in-line DevSecOps compliance certification that Enforce Forward Secrecy and other mobile app security features are in each build of the mobile app.

Using Threat-Events™ for Enforce Forward Secrecy Intelligence and Control in Mobile Apps

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

The specifications and options for Threat-Events™ for Enforce Forward Secrecy are:

Threat-Event™ Elements Use Enforce Forward Secrecy Method Detail
Appdome Feature Name Enforce Forward Secrecy
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).
