QA Testing Services for SaaS Startups: How Vervali Works
How Vervali tests a SaaS startup's product: what to test first, when to outsource, manual or automation, the monthly cost at published rates, and how the free pilot…
Mobile Security Testing
for iOS and Android Apps
The app, its storage and what it sends, tested with MobSF and Frida, with 100% coverage of agreed in-scope builds. We find what your iOS and Android apps leak before attackers, app store reviewers or your customers do.

What We Test in Your Mobile App
Every OWASP Mobile Top 10 risk on the builds you name, tested on real devices, not by a scanner alone.
App Binary
Hard-coded secrets, debug flags left on, weak obfuscation and how easily the app can be reverse engineered.
Local Storage
Tokens in plain text, backups that leak data, and sensitive values kept outside the Keychain or Keystore.
Login and Sessions
Weak login flows, missing multi-factor checks, sessions that never expire and role checks enforced only on the device.
Network Traffic
Missing certificate pinning, weak TLS settings and personal data leaving the device unencrypted.
Mobile APIs
The backend endpoints your app calls, tested for broken authorisation and data leakage. Deeper work runs through API security testing.
Runtime Protection
Jailbreak and root detection, tamper resistance and hooking defences tested with Frida on real devices.
An app store approval is not a security review.
Free App CheckMobile Risks We Close
Four gaps behind most mobile breaches, and what closes each one.
Leaky App Data
Closed with static and dynamic analysis, secure coding fixes and runtime protections.
Weak Login and Access
Multi-factor login, OAuth 2.0 and role-based access verified from the app to the server.
Exposed Backends
API testing, encryption checks and server-side hardening behind every screen.
Compliance Gaps
Findings mapped to OWASP Mobile Top 10, GDPR, HIPAA and PCI DSS. See compliance testing.
How We Test and Retest
Staging builds, real devices and a retest that proves every fix.
Scope and Builds
Apps, platforms, roles and environments agreed in writing. We test staging builds, so live users are never affected.
Static and Dynamic
MobSF for code and binary analysis, Frida for runtime hooking, and traffic interception on real devices.
Risk-Ranked Report
Risk ratings, proof and step-by-step fixes written for your iOS and Android developers.
Retest After Fixes
Every finding revalidated on the new build. 100% coverage of agreed in-scope builds.
Apps and Frameworks We Cover
Native, hybrid or cross-platform, tested against recognised mobile security standards.
Native iOS and Android
Apps built in Swift, Objective-C, Kotlin or Java, tested on current and older OS versions your users run.
Cross-Platform and Hybrid
React Native, Flutter, Xamarin and web view apps, including the bridges between native and web code.
Recognised Standards
Testing mapped to the OWASP Mobile Top 10 and MASVS, with CWE references and NIST guidance in the report.
Five Recent Engagements
Security work anonymized by sector, including mobile testing with MobSF and Frida on a SaaS gaming platform.
Bank · VAPT and audit evidence
Before: vulnerability noise was burying the work that mattered, fixes took over 40 days and audit preparation took five days. After: 68% less vulnerability noise, time to fix under 16 days, audit preparation down from 5 days to 5 hours, and high-risk findings closed 3.5 times faster.

Infrastructure VAPT across the exposed surface of a digital recharge and payments platform, using Burp Suite, Metasploit, Tenable, OpenVAS and Wireshark.
Marine Technology
Web and infrastructure VAPT for a global marine technology organisation, tested against the OWASP Top 10 with risk-ranked findings.
Fintech Platform
API VAPT on a fintech platform, focused on authorisation between accounts, the flaw class automated tools most often miss.
SaaS Gaming
End-to-end VAPT across web, mobile, API, source code and infrastructure, with MobSF and Frida on mobile and one retest.

Fits Your Releases
A retest for each release before it ships, with hours overlapping 9am to 1pm Eastern and delivery from India.
Frequently Asked Questions
Most engagements are priced at $25 to $49 an hour and quoted in tester-days once the scope is written down. For mobile, the price follows the number of apps, whether iOS, Android or both are in scope, the user roles to test, whether backend APIs are included and whether you need an audit-ready report. A retest is always included.
The main types are vulnerability assessment, penetration testing, static and dynamic application security testing, API security testing, mobile security testing, network testing, cloud configuration review and compliance testing. Mobile security testing covers the app binary, local storage, authentication, network traffic and the APIs behind the app, mapped to the OWASP Mobile Top 10 and tested on real devices.
Pentesting is legal only with written permission from the owner of the app and every system it talks to. Testing someone else’s app without consent is illegal, even if you downloaded it from a public store. We agree builds, environments, backend endpoints and test windows in writing first, and test staging builds so your live users are never affected.
For mobile security, five tools do most of the work: MobSF for static and dynamic analysis, Frida for runtime hooking, Burp Suite for intercepting app traffic, Objection for runtime exploration and jadx for reverse engineering Android builds. Tools surface likely issues. A tester on a real device confirms which ones an attacker can actually exploit.
A penetration test should be quoted in tester-days against a written scope. At $25 to $49 an hour, a single app on one platform with a retest is a focused engagement, while iOS and Android together with their backend APIs take longer. Ask each vendor to quote the same builds and roles so the proposals compare fairly.
Rankings change every year and many are paid, so judge vendors on evidence. For mobile work, ask whether they test on real devices, cover the OWASP Mobile Top 10 and MASVS, test the backend APIs, share a sample report, include a retest and hold ISO/IEC 27001. Vervali meets each of these and will share a sample report before you sign.
No. AI now helps scan code, suggest test cases and triage findings, which speeds up mobile testing. It still cannot reliably bypass a custom jailbreak check, chain a storage flaw with a weak API into a real account takeover, or judge business impact. That needs an experienced tester with the app on a real device, and every finding is verified by hand.
It is an authorised attempt to break into a web application the way an attacker would, covering login, sessions, access control, injection and business logic. Many mobile apps share the same backend and APIs as the web app, so we often test both together. Each finding comes with proof, a recommended fix and a retest after your team ships it.
