The Problem

Your App Store Review Checks Policy, Not Whether It Is Secure

Passing app store review means your app follows the store's rules. It says nothing about whether an attacker can read its data, copy its secrets, or tamper with it.

  1. Local data

    Tokens or personal data sit in readable local storage.

    Local data

    We test what the app stores and prove whether it is protected.

  2. Hard-coded keys

    An API key or secret is baked into the app binary.

    Hard-coded keys

    We decompile the build and find secrets before an attacker does.

  3. No pinning

    Traffic can be read on shared Wi-Fi without pinning.

    No pinning

    We test the network layer and confirm pinning holds.

  4. Backend trust

    The app is checked but the API behind it is not.

    Backend trust

    We test the backend API the app calls, with the same rigor.

Your app shipped, it passed store review, and the backend sits behind HTTPS. Still, nobody has looked at what happens once your app is on a real phone in the wrong hands. Does it leave tokens or personal data in storage that any file browser can read? Is an API key baked into the binary where a decompiler finds it in minutes? Can someone on the same Wi-Fi read the traffic because pinning was skipped? A web scan does not see your app, and your QA team tests features, not attackers. The gaps live in the parts nobody tested.

We test your app the way an attacker with the phone would. We install your real iOS and Android builds on test devices, including rooted and jailbroken ones, and check them against the OWASP MASVS. We look at what your app stores, how it encrypts, how it handles tokens and deep links, what secrets sit in the binary, and whether it resists tampering. Then we test your backend API. You get proof for each finding and a fix your developers can apply.

  • Tested on real devices

    We install the iOS and Android builds on test phones, including rooted and jailbroken ones, the way an attacker would.

  • Checked against the MASVS

    We test your app across the OWASP MASVS control groups, from storage and crypto to resilience, so nothing is skipped.

  • App and backend together

    We test your app and the backend API it talks to, because the worst findings usually cross between the two.

Our Mobile App Penetration Testing Process

From Test Build to a Fix List in Five Steps

You approve the scope and give us the builds. You watch each finding proven on a device, then get a report mapped to the MASVS, with a fix for every issue.

  1. You tell us your apps, the platforms, and the backend they use. We agree whether one or both platforms and the API are in scope, and the testing window. You sign an authorization form, and we lock a fixed price. We test only apps and systems you own or are authorized to test.

What's Included

What You Get With Mobile Application Penetration Testing

You get testing on real iOS and Android devices, a check against the MASVS, storage and crypto review, binary and tamper testing, backend API testing, and a retest.

  • On-device testing

    Your real iOS and Android builds tested on physical devices, including rooted and jailbroken phones.

  • MASVS coverage

    Your app is checked across the OWASP MASVS control groups, so your storage, crypto, network, and resilience are all covered.

  • Data and token review

    A review of what your app stores, how it encrypts data, and how it handles your tokens, sessions, and deep links.

  • Binary and tamper testing

    Your build is decompiled to find hard-coded secrets, and tested for whether it resists tampering and running on a rooted device.

  • Backend API testing

    We test the API your app calls for broken access, weak tokens, and logic flaws, since both share one attack surface.

  • MASVS-mapped report

    Every finding mapped to its MASVS group with proof, a severity score, and the exact fix your developers apply.

Projects We've Built

We design and ship native and cross-platform mobile apps, so we know where tokens, storage, and backend calls usually leak on a real device.

What Our Clients Say

What Clients Say After Launch

Feedback from teams we have built and shipped mobile apps for.

We had a pretty specific idea of what we wanted our website to become, but I wasn’t sure how easily we could explain all of it to a development team. There were quite a few moving parts, and we were working toward a deadline, so I expected a few things to get lost along the way. That never really happened. They understood what we were trying to achieve, kept us updated throughout the process, and got everything ready within the agreed timeline. The final site feels much easier to navigate, works beautifully on mobile, and is noticeably smoother for our customers. It was a huge relief seeing the original idea actually turn into the website we had in mind.

Work Culture

Why App Teams Trust Us With a Mobile Pen Test

Testing a mobile app means working on the device and in the backend at once. These habits keep the test thorough and the report easy for your developers to act on.

  • We test on real devices

    Your build runs on physical phones, including rooted and jailbroken ones. An attacker holds a real device, so that is where your app is tested, not only in a simulator.

  • We follow the MASVS

    Your app is tested against the OWASP MASVS, so coverage stays consistent and your report maps to a standard your auditors already know.

  • We confirm every finding

    Each issue is proven on a device or in the binary, with the steps to repeat it. You fix a confirmed problem, not a scanner's guess.

  • We test the backend too

    A secure app with a weak API is still exposed, so your backend is tested too. Many of the worst findings cross from your app into the backend it trusts.

  • We tell you what you need

    If functional QA or a web app test covers your case, we will say so before we quote. The test should match your real risk.

  • You own the results

    Every report, proof, and fix stays yours to keep and share with customers, auditors, or an app store review, during the engagement and after.

Good fit

  • Fintech and banking app teams

    You handle money or accounts in your app, and you need proof it protects tokens and data before a bank partner or auditor asks.

  • Health app teams

    Your app holds patient or health data, and you need to show it is stored and sent safely on the device and to the backend.

  • Teams facing a security review

    Your customer or partner asks for a recent mobile pen test, and you want a report mapped to the MASVS, not a scan export.

  • Apps with a public API

    Your app talks to an API that anyone can call, and you want the app and the backend tested as one attack surface.

  • Teams after a new release

    You just shipped a big update with new logins, payments, or deep links, and you want the new surfaces tested before users lean on them.

Not a fit

  • Functional QA

    You want crash, usability, and device testing, not security. Our Mobile App Testing page covers that kind of release testing.

  • Web app only

    Your product is a website or web app, not a mobile app. Our Web Application Penetration Testing Services page is the right fit.

  • Full code review

    You want a deep source code and design review, not a device test. Our Application Security Assessment page goes to that depth.

  • Budget under $1,300

    Your budget is under $1,300, or you only need a quick automated scan. A single-platform test is the smaller first step.

FAQ

Frequently Asked Questions

Straight answers on cost, timing, how the testing works, and the standard we test against.

  • Mobile app penetration testing services start at $1,300 for one platform tested on real devices against the MASVS. Testing both iOS and Android with the backend API runs $3,100. A full test with a backend cloud review and two retests starts at $5,800. You get a fixed quote after a free scoping call.

  • Most mobile tests take 1 to 2 weeks per platform, including hands-on work on real devices. Adding the backend API review takes up to 3 weeks, depending on how many platforms and backends are in scope. We retest once your team has shipped the fixes, usually within 60 days.

  • It is an authorized test of your iOS or Android app and its backend, run on real devices, to find weaknesses an attacker could use. Also called mobile application penetration testing or mobile app security testing, it checks what your app stores, how it protects data, and how it talks to its API. All of it maps to the OWASP MASVS.

  • We install your real build on test devices, including rooted and jailbroken ones, and work through the OWASP MASVS control groups. Our mobile application pentesting checks your storage, crypto, authentication, deep links, binary secrets, and tamper resistance. We decompile the app, read its traffic, and confirm each finding by hand, then test the backend API.

  • We treat your banking app as high-risk and test it harder. On top of the full MASVS checks, our mobile penetration testing looks at how tokens and session keys are stored and whether certificate pinning holds. We check whether it runs safely on a rooted phone, then test the banking backend API for access and logic flaws.

  • Yes. iOS and Android store data, pin certificates, and handle permissions differently, so a finding on one may not exist on the other. Our mobile app pen testing covers whichever platforms you ship, native or in React Native or Flutter. The two-platform plan tests both and shares one report.

  • Yes. A determined attacker will run your app on a rooted or jailbroken phone, so we test there too. We check whether the app detects the unsafe device, whether it still protects data and keys, and whether it can be tampered with. Penetration testing mobile applications without a rooted device misses a whole class of risk.

  • Yes, on the two-platform and full plans. A locked-down app is still exposed if its API is weak, so we test your backend for broken access between users, weak tokens, and logic flaws. You get the app and the API reviewed together, with findings in one ranked list.

  • We test against the OWASP Mobile Application Security Verification Standard (MASVS) and use its testing guide, the MASTG, for the method. Every finding is mapped to its MASVS control group, so your report lines up with a recognized standard. That makes it easy for your auditors and partners to read and trust.

  • You own the full report, the proofs, and the fix list, during the engagement and after it ends. Every plan includes at least one retest: once your developers apply the fixes, we retest each finding against its original proof and send an updated report. You can share that report with customers, auditors, or an app store review.
