A cloned app is your brand, your UI and your customers’ trust, in an attacker’s hands. SecIron stops repackaged copies from running and tells you where they are being tried.

A cloned app looks identical to the real one. It is distributed through phishing links and third-party stores, and it harvests logins and OTPs from customers who believe they are talking to you.
Integrity checks built into the hardened release mean a repackaged copy fails on first launch, and the attempt is reported to IronSKY with the device and region it came from.
Cloning needs no exploit. It needs your public APK, a decompiler and a channel to distribute the result.
Your app plus a credential stealer, re-signed and pushed through third-party stores and chat groups.
Fake apps advertised on social media and search, harvesting logins, OTPs and card numbers.
Builds with ads, licence checks or in-app purchases removed, costing revenue and support effort.
Smishing campaigns that convince users to install a cloned update outside the store.
Losses attributed to your app, regulator questions and takedown costs long after the fact.
Most organisations learn about a clone from a customer complaint, weeks after it went live.
Integrity protection makes a modified build refuse to start. Monitoring turns every refused launch into intelligence about the campaign behind it.
Identify what makes your current build easy to repackage.
Bind the build to its signature and contents.

International bankCase study · BankingHow SecIron helped an international bank meet its mobile security mandatesA central regulatory mandate required every banking app to be protected, within weeks. IronWALL was deployed on-premise for iOS and Android, with no SDK and no source code changes, so the bank could harden its app without slowing a single release.2 weeksto the first protected appMinutesto harden every update0source code changesRead the case study| Scenario | Before SecIron | With SecIron |
|---|---|---|
| Clone pushed through a third-party store | Runs and harvests credentials | Integrity check fails; the clone will not start |
| Smishing update campaign | Users install the fake | Fake refuses to run; attempts reported to IronSKY by region |
| Ad-free modified build | Revenue loss | Modified build will not run |
| Takedown prioritisation | Guesswork | Launch telemetry shows which clone campaigns are active |
| Regulator asks what happened | Reconstruction after the fact | Timestamped evidence of attempts and responses |
On its first launch. The hardened app verifies its own signature and integrity before it runs, so a modified copy fails immediately and the attempt is reported.
Yes, protection cannot stop someone uploading a file. It stops that file from working and gives you the evidence to request a takedown.
No. IronWALL protection is codeless: you upload the compiled APK, AAB or IPA, select the protection modules and receive a hardened build. There is no SDK to wire in and no source code access required.
Yes. SecIron protects native Android and iOS apps as well as Flutter, React Native, HarmonyOS and HarmonyOS Next, because protection is applied to the compiled app rather than the source.
