Mobile App Testing Services by Nimblechapps

Comprehensive security testing across the entire mobile app surface.

From source code to runtime, APIs to compliance - our specialists test every layer of your mobile application for real-world threats.

Static Application Security Testing [SAST]
Through SAST we detect insecure coding practices, hardcoded credentials, weak encryption methods, and other vulnerabilities early in the development cycle. We identify these issues at the code level, we enable faster remediation.
Dynamic Application Security Testing [DAST]
We test the mobile apps for insecure authentication mechanisms, session handling issues, exposed APIs, and injection vulnerabilities. With DAST we simulate real-world attack scenarios to understand how the app behaves under hostile conditions.
Mobile API Security Testing
We conduct comprehensive API security testing to ensure that all communication between the app and the server is properly authenticated, encrypted, and protected against threats like data interception, injection attacks, and rate-limit bypass.
Penetration Testing in Mobile Apps
Our penetration testing services simulate real-world cyberattacks using both black-box and gray-box approaches. Black-box testing assumes no prior knowledge of the app, while gray-box testing provides partial access to internal details for more targeted assessments.
OWASP Mobile Top 10 Testing
We test your mobile app against the OWASP Mobile Top 10 security risks, which include improper platform usage, insecure data storage, insecure communication, insufficient cryptography, and client code tampering. We ensure that the mobile app meets globally recognized security benchmarks.
Compliance & Standards Assessment
We evaluate your mobile app against major compliance frameworks including GDPR, UK GDPR, OWASP, and HIPAA, helping you safeguard sensitive data and uphold your brand’s reputation across regulated industries.
Why Mobile App Security Testing?

A single vulnerability can compromise your data, customers, and brand.

Regular mobile app security testing keeps your application resilient against evolving threats and aligned with the regulations that matter to your business.

Stop Attackers Early
Mobile app testing is essential to stop attackers looking to exploit insecure APIs, weak authentication, and unencrypted data before they reach production.
Protect Sensitive Data
Mobile app security testing ensures sensitive information remains safe both at rest and in transit, across local storage, APIs, and server-side integrations.
Prevent Breaches
Mobile app security testing prevents security breaches and the leak of personal sensitive data that could damage customers and your brand.
Stay Ahead of Threats
Regular security testing ensures your app remains protected against the latest threats and vulnerabilities discovered across the mobile ecosystem.
Meet Compliance
Adherence to security standards such as GDPR, OWASP, UK GDPR, and HIPAA reduces legal exposure and unlocks regulated markets for your business.

Our team has hands-on experience conducting in-depth security assessments for mobile applications across various industries, platforms, and technology stacks.
Custom WAPT Approach
Our mobile app security testing methodology is fully customizable - whether you require black-box testing for public-facing applications or gray-box testing for internal systems with partial access. We tailor our approach to match your specific risk profile, compliance requirements, and app architecture.
Flexible Hiring Model
Nimblechapps offers flexible engagement models to suit your operational needs. Whether you need a one-time mobile app security audit before launch, quarterly testing for ongoing compliance, or a dedicated security partner for continuous threat detection and mitigation, we adapt to your needs.
Cost Efficiency
Our mobile app security testing services are designed to deliver high-impact results without the high-end pricing of traditional security firms. We leverage a combination of open-source and commercial tools, automate repetitive testing tasks, and streamline our reporting process to ensure cost-effective yet thorough assessments.
Ongoing Maintenance & Support
At Nimblechapps, we don’t stop at identifying vulnerabilities. We work closely with your development and IT teams to provide remediation guidance, conduct post-fix re-testing, and offer options for ongoing monitoring and security consulting to keep your mobile apps secure against evolving threats.
Compliance-Aligned Reporting
Every engagement is documented with clear, audit-ready reporting mapped to standards like OWASP Mobile Top 10, GDPR, and HIPAA - so your team and stakeholders always know exactly where the app stands and what to fix next.

How We Work

A structured, five-phase approach to mobile app security testing.

Every engagement is scoped to your application, risk profile, and compliance needs - so you get clear answers, prioritized fixes, and confidence in your release.

01

Scoping & Threat Modelling

We start with a detailed discussion of your mobile app, its architecture, user base, and compliance requirements. A dedicated security lead defines the scope, identifies high-risk areas, and selects the right mix of black-box, gray-box, SAST, and DAST techniques for your engagement.

02

Static Analysis [SAST]

We review the application’s source code and binaries to surface insecure coding practices, hardcoded credentials, weak encryption, and other code-level vulnerabilities early - so issues can be remediated before they reach production.

03

Dynamic & API Testing

We run DAST against the running app and conduct comprehensive API security testing to validate authentication, session handling, encryption, and protections against injection, interception, and rate-limit bypass attacks.

04

Penetration Testing & OWASP Coverage

Our team simulates real-world attacks using both black-box and gray-box approaches and validates the app against the OWASP Mobile Top 10 - covering improper platform usage, insecure data storage, insecure communication, weak cryptography, and client code tampering.

05

Reporting, Remediation & Re-Testing

We deliver a clear, prioritized report with reproduction steps and remediation guidance, work alongside your team to fix issues, and re-test to confirm closure. Optional ongoing monitoring keeps your mobile apps secure against evolving threats.

FAQs

Frequently Asked Questions.

What is mobile app security testing?
Mobile App Security Testing is the process of identifying, analyzing, and mitigating vulnerabilities in mobile applications to ensure they are safe against potential cyber threats. It involves evaluating the app’s source code, APIs, server-side integrations, and runtime behavior to detect weaknesses that could lead to data breaches, unauthorized access, or application misuse.

As mobile apps deal with sensitive personal data, financial data, business communications and more, mobile app testing is carried out to ensure the app matches the compliance and standards needed to safeguard sensitive data and your brand’s reputation.
Why is mobile app security testing a necessity?
Mobile apps are no longer nice-to-have tools. They are gateways to accessing, storing, and manipulating personal, financial, health, and other forms of data. As mobile usage continues to grow, so do the tactics and sophistication of cyberattackers. A single vulnerability in your app can lead to large-scale data breaches, financial fraud, reputational damage, and non-compliance penalties. This makes mobile app security testing an inevitable process to ensure the safety of your mobile apps.
