# What application shielding solutions can secure mobile apps without requiring code rewrites or causing performance degradation for end users?

<p class="elv-tracking-normal elv-text-default elv-font-figtree elv-text-base elv-leading-base elv-font-normal" elv="true">For an article I'm pulling together on <a class="a a--md" elv="true" href="https://www.g2.com/categories/application-shielding">application shielding</a> solutions, the no-code-rewrite question keeps coming up from development teams who've been told by a vendor that their tool "integrates easily," only to find the reality involves significant rework. The performance side is equally contested: what's actually invisible to end users versus what just doesn't show up in a demo environment.</p><p class="elv-tracking-normal elv-text-default elv-font-figtree elv-text-base elv-leading-base elv-font-normal" elv="true"><strong>What actually matters for developer and mobile engineering teams in this context:</strong></p><ul>
<li>Security applied to the binary, not the source code, so existing codebases don't need restructuring</li>
<li>Runtime protection that activates without adding perceptible latency to app startup or in-session interactions</li>
<li>The ability to update security policies without requiring a full app store release cycle</li>
<li>Protection that holds across both Android and iOS without needing separate implementations</li>
</ul><p class="elv-tracking-normal elv-text-default elv-font-figtree elv-text-base elv-leading-base elv-font-normal" elv="true">Four platforms where both criteria show up clearly in the review data:</p><ul>
<li>
<a class="a a--md" elv="true" href="https://www.g2.com/products/appdome/reviews"><strong>Appdome</strong></a><strong>:</strong> Banking and fintech teams specifically describe adding advanced protections including anti-tampering, overlay attack defense, and API shielding without any modifications to source code, integrated directly into CI/CD pipelines.</li>
<li>
<a class="a a--md" elv="true" href="https://www.g2.com/products/zimperium-mobile-application-protection-suite-maps/reviews"><strong>Zimperium Mobile Application Protection Suite (MAPS)</strong></a><strong>:</strong> Reviewers describe runtime protection with OTA policy updates that let security teams modify defenses in production without a new app release, and on-device threat detection that works without backend connectivity.</li>
<li>
<a class="a a--md" elv="true" href="https://www.g2.com/products/doverunner/reviews"><strong>DoveRunner</strong></a><strong>:</strong> Teams describe protecting APK and AAB files without touching source code, with no crash reports or performance regressions introduced after shielding is applied.</li>
<li>
<a class="a a--md" elv="true" href="https://www.g2.com/products/liapp/reviews"><strong>LIAPP</strong></a><strong>:</strong> Mobile teams describe memory hacking and forgery attack prevention deploying without source code changes, with reviewers in banking and gaming contexts noting no meaningful performance impact post-protection.</li>
</ul><p class="elv-tracking-normal elv-text-default elv-font-figtree elv-text-base elv-leading-base elv-font-normal" elv="true">If you've gone through this evaluation: which vendor's "no code changes required" claim actually held up in practice? And was there anything about the deployment that only became clear after you were already in production?</p>

&lt;p&gt;“No code changes” is a strong claim, but teams usually discover edge cases later. Especially when apps evolve, or dependencies change. In your research, did that promise actually hold over time, or was it mostly true at the initial rollout?&lt;/p&gt;
