PreEmptive JSDefender is a commercial mobile app security tool by preemptive. PreEmptive DashO is a commercial mobile app security tool by preemptive. Compare features, ratings, integrations, and community reviews side by side to find the best mobile app security fit for your security stack.
CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
Startups and mid-market teams shipping JavaScript-heavy web and mobile apps need PreEmptive JSDefender to stop reverse engineering of client-side code before it becomes a support nightmare. The tool handles React, Angular, Vue, and Node.js natively while maintaining application functionality through code renaming and source transformation, eliminating the rebuild-and-test cycle that kills adoption. Skip this if your threat model doesn't include client-side IP theft or you're building server-only backends; obfuscation is defense-in-depth, not a perimeter control.
Mobile app teams shipping Java, Android, or Kotlin code should pick PreEmptive DashO when reverse engineering and tampering are genuine threats to your IP or user security, not hypothetical ones; the 11-layer obfuscation stack plus runtime tamper detection catches attacks that static analysis misses entirely. The tool's RASP capability and debug prevention give you active defense during execution, which matters more than pre-release hardening alone for apps handling sensitive transactions or authentication. Skip this if your threat model centers on network-layer attacks or you need protection across web and mobile simultaneously; DashO is deliberately mobile-first and won't replace your API security strategy.
