Mobile App VAPT · iOS & Android

Mobile app penetration testing from Sumrite for the app in every customer's pocket.

Mobile apps store tokens, call APIs, and run on devices you do not control. We test iOS and Android the way real attackers do — app, traffic, and server logic — so you ship updates with confidence.

What this helps you achieve

Keep on-device data safe

Find tokens and personal data left where other apps can read them.

Trust app-to-server connections

Validate encryption and whether traffic can be intercepted.

Meet enterprise and store requirements

Support security reviews from banks, healthcare, and global buyers.

Cover app and API together

One engagement tests the client and the backend it uses.

Sumrite’s testers run your mobile app VAPT by hand, and the report is issued through a CERT-In empanelled auditor. One team from scoping to sign-off, built for Indian regulators, enterprise buyers and government work.

  • Accepted where it is requiredRegulators, auditors and procurement teams that ask for a CERT-In empanelled auditor’s report, including SEBI-regulated entities and government and PSU contracts.
  • One team, one contractSumrite handles scoping, testing, the report and the retest. You do not manage a second vendor.
  • Real testing, not a scanManual exploitation with evidence for every finding, and a retest after your fixes.

Can Sumrite also arrange the formal step for me?

Yes. We run the full engagement for you and route the formal attestation through our network of CERT-In empanelled partner auditors, so you deal with one team from scoping to report.

What is mobile app VAPT?

Mobile app VAPT is an expert-led security assessment of an iOS or Android app together with the backend it talks to. The app runs on devices you do not control, so a tester looks at it the way an attacker with the installed app would: what it stores on the phone, which secrets are built into the binary, whether its traffic can be intercepted or altered, and whether deep links or exported components let other apps reach screens that should need a login. Because most real damage happens server-side, the APIs the app calls are tested in the same engagement. The work follows the OWASP Mobile Application Security Verification Standard (MASVS) and the OWASP Mobile Top 10. The report separates app-side and server-side findings, rates each one, and gives fixes for both mobile and backend developers, with re-testing included.

How Sumrite mobile testing maps to OWASP MASVS

MASVS groupWhat Sumrite tests
MASVS-STORAGETokens, personal data and keys stored on the device, logs, backups and caches
MASVS-CRYPTOWeak algorithms, hard-coded keys and misuse of the platform keystore
MASVS-AUTHLogin, session handling, biometrics and the server-side checks behind them
MASVS-NETWORKTLS configuration, certificate pinning and traffic interception
MASVS-PLATFORMDeep links, exported components, WebViews and inter-app communication
MASVS-CODEThird-party libraries, input handling and debug code left in release builds
MASVS-RESILIENCERoot and jailbreak detection, tamper and reverse-engineering protections
MASVS-PRIVACYData collected, permissions requested and what leaves the device

OWASP MASVS (Mobile Application Security Verification Standard) groups mobile security into eight control areas. Sumrite tests each one on real Android and iOS builds, together with the APIs behind the app.

What Mobile App VAPT covers

AreaWhat we checkExample finding
Local storageTokens, personal data and keys left on the deviceAn auth token in plain text in shared preferences
Network securityTLS, certificate validation and pinning, traffic tamperingThe app accepts an intercepting proxy's certificate
Platform interactionDeep links, intents, URL schemes, WebViewsA deep link opens the account screen without logging in
Binary and secretsHard-coded API keys, debug flags, obfuscationA third-party API secret extracted from the app package
Backend APIsThe same access and authentication checks as an API testOne user's app session reads another user's records

How an engagement runs

  1. Scope and NDA. Tell us what needs testing and why. You get a fixed-price quote and an NDA is signed before any technical detail changes hands.
  2. Rules of engagement. Targets, test windows, accounts, safety contacts and anything off-limits are agreed in writing before testing starts.
  3. Expert-led testing. A researcher tests by hand, using tools to speed up the routine parts. Every finding is reproduced and confirmed before it is reported.
  4. Report. An executive summary for leadership, then each finding with a CVSS severity, the evidence, steps to reproduce and a fix your team can apply.
  5. Re-test. Once fixes are in, we test them again and record the result, so the final report shows what was found and what is now closed.

Mobile App VAPT: common questions

What do you need for a mobile app test?

An IPA or APK build, or TestFlight and internal-track access, plus test accounts. A build without heavy obfuscation speeds up the work; release-build checks can be added if needed.

Read this in the FAQ →

Do you test iOS and Android separately?

They can be tested together or separately. Where both apps share a backend, the API is tested once and the platform-specific checks are done on each app.

Read this in the FAQ →

Does an app store review replace a security test?

No. Store review checks policy and obvious malware. It does not test your access control, data storage or backend APIs, which is where most real mobile breaches start.

The problem & our approach

Users assume your app is safe — one flaw can expose everyone.

Hardcoded keys, weak storage, and deeplinks that skip login are common and rarely caught by store scans alone.

Sumrite's Mobile App VAPT combines static review, runtime testing, and API assessment with proof-backed findings.

  • Clear report for product and engineering leaders
  • Re-test included before report
  • Accepted for compliance audits and vendor reviews worldwide
For engineering & security teams

Technical overview

Methodology, scope, and deliverables in plain terms.

How we test

OWASP MASVS and Mobile Top 10 themes: storage, network, platform interaction, and resilience.

  • iOS and Android (native, Flutter, React Native)
  • Permissions and local storage
  • Backend APIs used by the app

What you receive

Risk-rated findings, reproduction steps, and fix guidance. Report after verified remediation.

Your Mobile App VAPT journey

Every step from scope and NDA to a retested, final report, shown for Mobile App VAPT. No jargon, no surprises.

Step 1 of 6

Request your mobile test

Submit your scope so our team can plan the engagement and get started.

  • Share iOS and Android builds (IPA, APK) or store links
  • Backend and API scope, with test accounts
  • Confirm platforms and minimum OS versions
  • NDA and testing authorisation signed first
Step 2 of 6

Expert assessment: Mobile App VAPT

Every phase is run by a security expert, with tools used only to speed up the routine parts. Findings are reproduced and confirmed before they reach your report.

Static analysis

  • Decompile and review the binary, manifest and entitlements
  • Hard-coded secrets, keys and endpoints
  • Insecure storage design and third-party SDK risk

  • Local storage, keychain, keystore, logs and clipboard
  • Certificate pinning and root or jailbreak detection bypass
  • Deep links, intents and inter-app communication abuse

Network and backend

  • Traffic interception and TLS validation
  • API authorisation behind the app: token reuse, BOLA
  • Server-side checks the client wrongly enforces

OWASP MASVS coverage

  • Storage, crypto, authentication, network, platform, code and resilience requirements
Expert-only work: beyond scanners and AI
  • Reverse-engineering custom protections and bypassing them live

  • Judging real exploitability on a lost or stolen device
  • Chaining an app weakness with an API flaw
Step 3 of 6

Draft report in 48 hours

Findings are written for two readers at once: developers who need the exact fix and auditors or buyers who need confidence.

  • Executive summary for leadership and auditors
