What is mobile app penetration testing?

Mobile app penetration tests uncover and exploit security vulnerabilities or misconfigurations in apps built for Android, iOS and other platforms. By revealing security flaws affecting mobile app architecture, mobile app pen tests give you actionable insights for building security by design features into your SDLC. Mobile application penetration testing is the best way to make sure you’re safeguarding end user data and protecting your reputation.

Benefits of Mobile App Testing

  • Find Security Flaws

    Pinpoint vulnerabilities such as insecure data storage, input validation issues, and authentication weaknesses

  • Comply with Regulations

    Meet regulatory requirements related to mobile app security, such as GDPR, HIPAA, or industry-specific standards

  • Improve User Trust

    Demonstrating a commitment to security enhances user trust in your mobile application and your organisation in general

How does mobile app pen testing work? How does mobile app pen testing work?

How does mobile app pen testing work?

During a mobile app pen test a qualified Bulletproof penetration tester takes on the role of a hacker and attempts to exploit a mobile application using the latest tools and technologies. The goal is to discover, document and prioritise all security flaws so that they can be remediated before cyber criminals exploit them.

We do this by using all methods available, including dynamic and static application security testing, DAST and SAST. SAST source-code reviews are insightful ways to uncover coding errors that could introduce security vulnerabilities. SAST can also help secure the software development lifecycle (SDLC), protecting data and preventing breaches at the earliest stages.

Benefits of Mobile Application Penetration Testing

The omnipresent nature of mobile apps makes them an attractive opportunity for cyber criminals. Releasing a mobile application with cyber security risks could have a massive impact on your reputation and finances. Mobile penetration testing helps you understand the risks of your mobile application, with minimal disruption to your business.

There are also compliance considerations – if your app collects or processes data for UK or EU citizens, you need mobile application penetration testing to maintain compliance with the GDPR. Regular mobile app pen testing is also an essential part of a secure software development lifecycle (SDLC).

  • Uncover vulnerabilities and poor security strategies
  • Exploit mobile application security flaws
  • Expose insecure functionality in your mobile app
  • Help improve security throughout your software development lifecycle

We know the threat landscape is dynamic and constantly evolving which is why we offer 12-months of free vulnerability scanning with every penetration test package.

Bulletproof mobile app pen testing methodology

Bulletproof follows industry standard best practices for our penetration testing methodology

Scope definition & pre-engagement interactions

Based on your defined goals, we’ll work with you to develop a tailored testing strategy.

Intelligence gathering & threat modelling

In this reconnaissance stage, our experts use the latest groundbreaking techniques to gather as much security information as possible about the mobile apps in the scope.

Vulnerability analysis

This is the stage where our penetration testers use industry leading tools and sector knowledge to find out what is leaving your cloud assets open to attack.


Using a combination of pre-existing software and custom-made exploits, our cloud pen testers will attempt to infiltrate your remote infrastructure and cloud-based technologies without causing any real-world disruption to your business.


The team will determine the risks and pivot to other systems and networks if within the scope of the test. All compromised systems will be thoroughly cleaned of any scripts.


Our security team will produce a comprehensive report with their findings. Once received, we’ll invite you for a collaborative read through. You’ll have the opportunity to ask questions and request further information on key aspects of your test.

Mobile app testing FAQs

Bulletproof mobile app tests use a blend of advanced automated tools and manual expertise to uncover security weaknesses, including OWASP Top 10 mobile vulnerabilities:

  • Improper Platform Usage
  • Insecure Data Storage
  • Insecure Communication
  • Insecure Authentication
  • Insufficient Cryptography
  • Insecure Authorization
  • Client Code Quality
  • Code Tampering
  • Reverse Engineering
  • Extraneous Functionality

Testing can be performed against a non-production replica of your live environment, such as a UAT/QA environment, to ensure no risk to your live services. If testing against production is unavoidable, we can coordinate our testing activities to minimise the impact. You can also specify things like no denial of service (DoS), meaning tests will have a negligible impact on your day-to-day operations.

  • Small apps, networks, cloud systems: 2-3 days
  • Medium apps, networks, cloud systems: 5-10 days
  • Larger apps, networks, cloud systems: 10 days+

All tests are tailored to you so use this as a guide.

Integrating mobile app pen testing into your SDLC is the best way to ensure continuous security. As a minimum, it’s recommended to pen test your mobile app during its development and additionally just before you launch the app. It’s also recommended that mobile applications are tested at least once a year as well as after any significant UI or software updates.
