How to Detect Remote Proxies in Mobile Apps Using AI

Last updated March 6, 2025 by Appdome

This Knowledge Base article describes how to use Appdome’s AI/ML in your CI/CD pipeline to continuously deliver plugins that Detect Remote Proxies in Mobile apps.

What are Remote Proxies?

Remote proxies are intermediary servers that route a device’s internet traffic through an external network, masking the original IP address and modifying the data flow between a mobile app and its backend servers. While commonly used for privacy, content filtering, and performance optimization (e.g., corporate VPNs, CDN services, and proxy servers like Squid, SOCKS5, and Tor), remote proxies can also be exploited by attackers to intercept, manipulate, or reroute app traffic for malicious purposes.
Cybercriminals use remote proxies to perform Man-in-the-Middle (MitM) attacks, session hijacking, and fraudulent transactions by modifying requests and responses between a mobile app and its legitimate server.

Remote proxies can also bypass geo-restrictions, anonymize malicious activity, and evade security controls designed to detect unauthorized access. In mobile banking, fintech, and e-commerce apps, attackers use remote proxies to spoof locations, evade anti-fraud measures, or automate large-scale credential stuffing attacks. Detecting and blocking unauthorized remote proxies is critical to preventing traffic manipulation, securing encrypted communications, and ensuring compliance with regulations like PCI DSS, PSD2, and GDPR.

How Appdome Protects Against Remote Proxies?

Appdome’s dynamic Detect Remote Proxies plugin for Android and iOS apps prevents unauthorized proxy usage by identifying traffic routed through remote proxy servers like SOCKS5, Squid, and Tor. The plugin monitors anomalies in SSL/TLS connections, DNS resolutions, and traffic routes to detect proxy-based manipulation. When a remote proxy is identified, Appdome can block connections, terminate sessions, or trigger enforcement actions to secure app communications against fraud and interception. This protection ensures real-time defense against traffic manipulation and network-based attacks, all without requiring developer effort.

Prerequisites for Using Appdome's Detect Remote Proxies Plugins:

To use Appdome’s mobile app security build system to Detect Remote Proxies , you’ll need:

How to Implement Detect Remote Proxies in Mobile Apps Using Appdome

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

      1. Create and name the Fusion Set (security template) that will contain the Detect Remote Proxies feature as shown below:
        fusion set that contains Detect Remote Proxies

        Figure 1: Fusion Set that will contain the Detect Remote Proxies feature

      2. Follow the steps in Sections 2.2-2.2.2 of this article to add the Detect Remote Proxies feature to your Fusion Set via the Appdome Console.

      3. When you enable Proxy Detection you'll notice that the Fusion Set you created in step 2.1 now bears the icon of the protection category that contains Detect Remote Proxies.

        Figure 2: Fusion Set that displays the newly added Detect Remote Proxies 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 Detect Remote Proxies feature to your security template.

      1. Navigate to Build > Security tab > Secure Communication section in the Appdome Console.
      2. Toggle On Proxy Detection > Detect Remote Proxies.
        Note: The checkmark feature Detect Remote Proxies is enabled by default, as shown below.

        (a) Choose to monitor this attack vector by checking the Threat Events checkbox associated with Detect Remote Proxies 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 XDR.
        Detect Remote Proxies option

        Figure 4: Selecting Detect Remote Proxies

      3. Select the Threat-Event™ in-app mobile Threat Defense and Intelligence policy for Detect Remote Proxies:
        1. Threat-Events™ OFF > In-App Defense

          If the Threat-Events™ setting is not selected. Appdome will detect and defend the user and app by enforcing Remote Proxies.

        2. Threat-Events™ ON > In-App Detection

          When this setting is used, Appdome detects proxies 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™ to Detect Detect Remote Proxies Intelligence and Control in Mobile Apps.

        3. Threat-Events™ ON > In-App Defense

          When this setting is used, Appdome detects and defends against Remote Proxies (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 Detect Detect Remote Proxies Intelligence and Control in Mobile Apps.

    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 Detect Remote Proxies protection is now added to the mobile app
  3. Certify the Detect Remote Proxies feature in Mobile Apps

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

Using Threat-Events™ for Remote Proxies Intelligence and Control in Mobile Apps

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

The specifications and options for Threat-Events™ for Remote Proxies are:

With Threat-Events™ enabled (turned ON), Mobile developers can get detailed attack intelligence and granular defense control in Mobile applications and create amazing user experiences for all mobile end users when Remote Proxies are detected.


The following is a code sample for native Mobile apps, which uses all values in the specification above for Detect Remote Proxies:


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 Detect Remote Proxies. 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.
