App shielding usually describes products that combine code hardening with runtime checks. RASP focuses on security decisions made while the application is running.
Evaluation approach
Vendors may use the same term differently. Comparisons should identify the code being protected, the event that triggers a check and the available response, rather than relying on a product label.
Application example
In an iOS project, assess Swift code, Objective-C bridges and native libraries separately. A single box marked as supporting iOS does not explain that scope.
Limits and considerations
The presence of obfuscation does not establish that integrity checks exist. Integrity checks, in turn, do not establish that the server enforces their results.
Four areas to separate in a proposal
A product proposal should distinguish transformations that make code harder to read, runtime detections, local responses and data sent to the server. These categories expose both the integration work and the areas left outside protection.
The same commercial package may apply different methods to Android bytecode and iOS native code. Ask which modules are excluded and how support is maintained as build tools change. One checkmark in a feature table cannot explain platform-specific behavior.
Checks and decisions
- Separate protection layers
- Verify platform coverage
- Record excluded code
