How Appdome SiteTrust Prevents Unauthorized Access to Your PWA

Last updated August 28, 2023 by Appdome

Appdome SiteTrust is a Secure PWA feature that protects non-public resources by restricting access/navigation to the home domain only, preventing unauthorized access to the mobile app’s backend and sensitive systems. When enabled, your SecurePWA app will only be able to access trusted domains and sites.

About Appdome SecurePWA

Appdome SecurePWA is a no-code mobile development tool that enables anyone to build secure Android and iOS progressive web apps (PWAs) that run as native or cross-platform Android and iOS apps on any mobile device – instantly, with no code or coding. The only requirement needed to create a Secure PWA is the URL of any existing website, web app, or cloud app. Developers or non-developers use Appdome’s simple ‘click to create’ user interface to build a progressive web application from any responsive website and add a wide variety of mobile security, SDKs, and APIs to their newly created Android and iOS apps in minutes – also with no code or coding.

The end result is a brand new iOS, Android or cross-platform app built entirely from scratch in seconds. Once the new app is created, customers instantly secure the app by selecting their choice of Appdome Mobile App Security features to build-in the required security model directly into the app – all within the same no-code workflow.

Appdome offers SecurePWA as part of Appdome-DEV.  SecurePWA dramatically accelerates enterprise mobile strategies. Organizations build true mobile apps from websites in minutes and offer users easy and persistent mobile app access to digital resources, offline use and more, all with the confidence of the enterprise security model chosen by the organization.

After Building Your PWA

After you have converted your website to a PWA, you need to move your PWA through the Appdome workflow. Just like with any other app that you build and secure using Appdome, click on the newly created PWA in your account, then select the services and security features you wish to implement in your PWA. Then click Build My App.

The minimum set of services required to secure your PWA is ONEShield by Appdome.  (Appdome’s no-code App shielding/hardening solution).  ONEShield prevents tampering,  malicious reverse engineering, debugging and any other unauthorized changes to your new PWA.  After building ONEShield into your app, you will now have a Secure PWA.

After you finish building your SecurePWA on Appdome, there are a few additional steps needed to complete your project, including signing your app.
