How to Secure Mobile Apps with Pin to Host Identity Using AI

Last updated July 9, 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 Pin to Host Identity in Mobile apps.

What is Pin to Host Identity?

Pin to Host Identity secures communication between the protected mobile application and trusted backend services by validating the identity of the server during TLS establishment. By ensuring that connections are established only with trusted hosts whose identities match the configured pinning policy, Pin to Host Identity helps prevent Man-in-the-Middle (MitM) attacks and unauthorized server impersonation.

How Appdome Protects Mobile Apps with Pin to Host Identity

Appdome’s Pin to Host Identity validates the configured server identity using the selected pinning strategy before establishing secure communication. Connections that fail the configured pinning validation are rejected, preventing communication with unauthorized or impersonated servers.

By validating server identity before any protected communication occurs, Pin to Host Identity helps prevent Man-in-the-Middle (MitM) attacks while ensuring that mobile applications communicate only with trusted backend services. The selected pinning strategy determines whether validation is performed against the server’s public key, leaf certificate, or trusted Root Certificate Authority.

When Packet Filtering Authorization and the appropriate MobileBOT™ Defense payload options are enabled, Appdome can provide additional server certificate metadata—including certificate Common Names (CNs), issuers, and SHA1 fingerprints—to backend services or Web Application Firewalls (WAFs) for logging and policy enforcement.

Supported Pinning Schemes

Pin to Host Identity supports multiple certificate pinning strategies, allowing organizations to choose the approach that best matches their security and operational requirements.

Public Key (SPKI) Pinning (Recommended)
Pins the server’s public key rather than the entire certificate. This is the recommended approach because certificates can be renewed without requiring an application update, provided the same public/private key pair is retained.

Leaf Certificate Pinning
Pins the complete leaf certificate presented by the server. This provides the strictest validation but requires the application to be updated whenever the server certificate is renewed or replaced.

Root CA Pinning
Pins the trusted Root Certificate Authority instead of the leaf certificate. Leaf certificates may be renewed without requiring an application update, provided they continue to chain to the same trusted Root Certificate Authority. Using a different Root Certificate Authority requires updating the pinning configuration to avoid breaking secure connections.

Choosing the Appropriate Pinning Strategy

Public Key (SPKI) Pinning is the recommended approach for most deployments because it provides strong security while allowing seamless certificate renewals without application updates.

Leaf Certificate Pinning is recommended for highly controlled environments where maximum certificate validation is required. Be aware that every certificate renewal requires updating the application.

Root CA Pinning is recommended when operational flexibility is preferred over maximum strictness. Leaf certificates may be renewed without requiring an application update, provided they continue to chain to the same trusted Root Certificate Authority. Using a different Root Certificate Authority requires updating the pinning configuration to avoid breaking secure connections.

Protected Host Configuration

Pin to Host Identity is applied only to connections matching the configured Protected Host. Configure the Protected Host by specifying the hostname or backend API endpoint that should be protected.

Prerequisites for Using Appdome's Pin to Host Identity Plugins:

To use Appdome’s mobile app security build system to Use Pin to Host Identity , you’ll need:

Appdome account (create a free Appdome account here)
A license for Pin to Host Identity
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 Pin to Host Identity in Mobile Apps Using Appdome

On Appdome, follow these 3 simple steps to create self-defending Mobile Apps that Use Pin to Host Identity without an SDK or gateway:

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. Pin to Host Identity is compatible with: Obj-C, Java, JS, C#, C++, Swift, Kotlin, Flutter, React Native, Unity, Xamarin, and more.
Select the defense: Pin to Host Identity.

Create and name the Fusion Set (security template) that will contain the Pin to Host Identity feature as shown below:

Figure 1: Fusion Set that will contain the Pin to Host Identity feature

Follow the steps in Sections 2.2-2.2.2 of this article to add the Pin to Host Identity feature to your Fusion Set via the Appdome Console.

When you select the 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 Pin to Host Identity.

Figure 2: Fusion Set that displays the newly added Pin to Host Identity 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.

Add the Pin to Host Identity feature to your security template.

Navigate to Build > API & Bot Protection tab > MobileBOT™ Defense section in the Appdome Console.
Like all other options in ONEShield™, Pin to Host Identity is turned on by default, as shown below:
Figure 4: Selecting Pin to Host Identity
Note: The App Compromise Notification contains an easy to follow default remediation path for the mobile app end user. You can customize this message as required to achieve brand specific support, workflow or other messaging.

Toggle On > Pin to Host Identity.

(a) Choose to monitor this attack vector by checking the Threat Events checkbox associated with Pin to Host Identity as shown below.

(b) To receive mobile Threat Monitoring, check the ThreatScope™ box as shown below. For more details, see our knowledge base article on ThreatScope™ Mobile XTM.

Figure 4: Selecting Use Pin to Host Identity
Note: The Appdome Platform displays the Mobile Operation Systems supported by each defense in real-time. For more details, see our OS Support Policy KB.

Select the Threat-Event™ in-app mobile Threat Defense and Intelligence policy for Pin to Host Identity:

Threat-Events™ OFF > In-App Defense
If the Threat-Events™ setting is not selected. Appdome will detect and defend user and app by enforcing Pin to Host Identity.

Threat-Events™ ON > In-App Detection
When this setting is used, Appdome detects the Certificate Pinning has failed and passes Appdome’s Threat-Event™ attack intelligence to the app’s business logic for processing, enforcement, and user notification. For more information on consuming and using Appdome Threat-Events™ in the app, see section Using Threat-Events™ for Use Pin to Host Identity Intelligence and Control in Mobile Apps.

Threat-Events™ ON > In-App Defense
When this setting is used, Appdome detects and defends against Pin to Host Identity (same as Appdome Enforce) and passes Appdome’s Threat-Event™ attack intelligence to the app’s business logic for processing. For more information on consuming and using Appdome Threat-Events™ in the app, see section Using Threat-Events™ for Use Pin to Host Identity Intelligence and Control in Mobile Apps.

Configure the User Experience Options for Pin to Host Identity:
With Threat-Events™ OFF, Appdome provides several user experience options for mobile brands and developers.

App Compromise Notification: Customize the pop-up or toast Appdome uses to notify the user when a threat is present while using the protected mobile app.

Short message Option. This is available for mobile devices that allow a banner notification for security events.

Localized Message Option. Allows Appdome users to support global languages in security notifications.

Pin to Host Identity Threat Code™. Appdome uses AI to generate a unique code each time Pin to Host Identity is triggered by an active threat on the mobile device. Use the code in Appdome Threat Resolution Center™ to help end users identify, find and resolve active threats on the personal mobile devices.

Optional Configuration with Pin to Host Identity:

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 Pin to Host Identity protection is now added to the mobile app

Certify the Pin to Host Identity feature in Mobile Apps

After building Pin to Host Identity, Appdome generates a Certified Secure™ certificate to guarantee that the Pin to Host Identity protection has been added and is protecting the app. To verify that the Pin to Host Identity protection has been added to the mobile app, locate the protection in the Certified Secure™ certificate as shown below:

Figure 6: 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 Pin to Host Identity has been added to each Mobile app. Certified Secure provides instant and in-line DevSecOps compliance certification that Pin to Host Identity and other mobile app security features are in each build of the mobile app.

Using Appdome, there are no development or coding prerequisites to build secured Mobile Apps by using Pin to Host Identity. 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 Pin to Host Identity

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.
