Android app protection.
iOS app protection.
Understand how to protect your code, data and critical transactions. Platform controls, security tools, testing methods and release decisions in one practical resource.
Three questions. A clearer security plan.
What are you protecting?
Code, personal data, sessions and financial transactions need different controls. Set priorities by concrete business impact.
Where is the decision made?
Connect device signals with server authorization. Distinguish client claims from verified evidence.
How do you know it works?
Measure detection, enforcement, performance and legitimate user experience in the same acceptance plan.
Understand how the layers fit together.
The Android application trust chain
From package signing to API decisions, assess protection as one workflow. Play Integrity, Keystore, component permissions and runtime defenses perform different jobs.
Start readingUnderstand the iOS platform boundaries
App Attest, Keychain, Secure Enclave and signing solve different problems. Examine where data resides and where transaction authority is enforced.
Start readingMatch the tool to the question
Compare protection products, analysis tools and testing methods by purpose, expected output and coverage. Understand what each result can establish.

An application protection threat model for Android and iOS
Prepare the threat model before assembling a product list. Identify the asset, the operation in which it needs protection and the capabilities of the attacker it must…
Read the guideComparing application protection, Play Integrity and App Attest
Runtime protection and platform attestation provide different trust sources.
Read the guideAn impartial guide to comparing application protection products
Compare products using the same package and tests. Marketing features are a starting point; security effects, user experience and operational work require observation.
Read the guideAndroid WebView security and RASP
WebView introduces a separate content and execution boundary inside an application.
Read the guideiOS file data protection
File protection extends beyond the main database. Previews, temporary files and sharing copies also form part of an iOS application's data surface.
Read the guideDefining success in an app protection proof of concept
A proof of concept tests security and operational expectations in your own application, rather than simply demonstrating a product.
Read the guideMore than a checklist.
Read the primary references, examine the assumptions and adapt each protection decision to your own application.
