Make your app the only trusted client of your APIs
Mobile APIs are abused from outside the app far more often than from inside it. SecIron ensures requests come from a genuine, untampered build on a trustworthy device, and shows you when they do not.
Your API is only as trusted as the app calling it
Once an attacker strips certificate pinning or scripts the app, your backend cannot tell a real session from a replayed or automated one. Rate limits and WAF rules see legitimate-looking traffic.
Hardening makes the protected app the only trusted client, and IronSKY shows you the moment someone tries to reach your APIs from anything else.
How mobile APIs get abused
Once an attacker understands how the app talks to your back-end, they no longer need the app at all.
Endpoint mapping
Reverse engineering reveals every route, parameter and auth header your API expects.
Pinning bypass
Stripped or hooked certificate pinning lets traffic be intercepted, read and modified in transit.
Stolen tokens and keys
Session tokens and API keys lifted from the app and replayed from scripts.
Bot and scripted traffic
Account creation, scraping, credential stuffing and promo abuse at machine speed.
Impersonating clients
Modified apps or custom clients that present themselves as your official app.
Business logic abuse
Legitimate calls made in illegitimate sequences to skip steps, limits or checks.
Trust the client, not just the credential
A valid token proves someone has a token. App integrity, device state and runtime signals prove the request came from your app, running as you shipped it.
Assess with IronSCAN
Find API weaknesses in the client before attackers do.
- Weak or missing certificate pinning
- Tokens stored or logged insecurely
- Sensitive endpoints exposed in code
Harden with IronWALL
Harden the client so calls can only come from an intact app.
- Hardened pinning that resists hooking
- Anti-tampering and integrity verification
- Root, emulator and instrumentation detection
Monitor with IronSKY
See which requests come from compromised clients.
- Device-risk signals to feed your API gateway
- Tampered-client and emulator telemetry
- Evidence for fraud and security teams
How teams like yours protect their apps with SecIron
See how an international bank made sure only its genuine, untampered app runs, on devices it can trust.
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 studyWhat changes once the app is protected
| Scenario | Before SecIron | With SecIron |
|---|---|---|
| Traffic intercepted on a rooted phone | Requests read and modified in transit | Hardened pinning holds; interception attempt detected |
| Session token replayed from a script | Back-end accepts it | Token bound to app integrity and device state; replay flagged |
| Custom client calls the API | Indistinguishable from the real app | Runtime signals show the request did not originate from an intact build |
| Emulator farm creates accounts | Bots scale freely | Emulators detected; sessions blocked before the API call |
| Logic abuse via call sequence | Steps skipped | Tampering needed to skip steps is detected and reported |
Frequently asked
Does SecIron replace an API gateway or WAF?
No. Those protect the server side. SecIron protects the client side and supplies device and app-integrity signals that make gateway and fraud decisions far more accurate.
Can device-risk signals feed our gateway or SIEM?
Yes. IronSKY exposes attack and device-risk events that can feed your API gateway, fraud engine and SIEM, so a flagged device can influence decisions in the tools you already use.
Do our developers need to change code?
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.
Will protection affect app performance?
Modern hardening is designed to provide strong security with minimal impact on performance. Implemented correctly, users experience little to no noticeable difference in launch time or responsiveness.
