Specific Concepts for App Developers (Mobile, Web, Desktop)

That SDK you just integrated or the API your app calls? Under the EU Cyber Resilience Act, you are now responsible for how it impacts your app's security. This act redefines your role as an app developer into that of a 'manufacturer', making you liable for the entire security posture of your product, whether it's a mobile app, desktop program, or PWA. Your responsibility extends to every component: the third-party libraries you use, the way you secure databases and user authentication, and the services you connect to. Relying on an app store's review process is not enough; you must conduct your own risk assessment and maintain your own compliance documentation. The biggest shift is that this is not a one-time check. The CRA demands continuous vulnerability management and security updates throughout your app's entire support period. This is the new baseline for shipping apps in the EU.
