The models' case: The de facto standard for mobile app analysis — open-source, covers both iOS and Android, combines static analysis (source and compiled IPA/APK) with a. The models' main caveat: Its static engine is rule/pattern-based with meaningful false positives and shallow dataflow. The strongest alternative is NowSecure — The enterprise standard for continuous automated mobile pipeline security (near-tie with Oversecured on mobile vulnerability coverage and MASVS.
