Most penetration testing follows a 6-step lifecycle:

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 web apps and sites in the remit.

Vulnerability analysis

This is where our website penetration testers get testing. Using the latest tools and sector knowledge, we’ll uncover what’s making your critical assets vulnerable and at risk from attack.


Using a range of custom-made exploits and existing software, our mobile app penetration testers will test all core infrastructure and components of the mobile app without disrupting 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.

Frequently asked questions

What is mobile application penetration testing?

A mobile application penetration test is a comprehensive security review where a qualified tester takes on the role of a hacker. They’ll attempt to uncover and exploit security vulnerabilities or misconfigurations specific to your mobile application. Mobile application penetration testing provides vital information on how to secure your app and, ultimately, helps keep your organisation and its customers secure online.

What vulnerabilities do you look for in a mobile application?

Bulletproof believes in working to the very best standards, so all our mobile application tests include the Open Web Application Security Project (OWASP) mobile Top 10 vulnerabilities as a minimum. We use a blend of advanced automated tools and manual expertise to uncover security weaknesses. This includes but is not limited to:

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

Bulletproof recommends a blend of all three testing types to get the most value from your penetration testing engagement and understand all the risks.

How long does a test normally take?

  • 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.

Will my business be disrupted during the test?

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.

Do you offer free retests?

Whilst we do not offer free retesting, we do offer 12-month vulnerability scanning.

Do you recommend other tests to complement certain pen tests?

Regular and comprehensive assessments of your cyber security are always recommended. The ramifications of security breaches can result in severe financial and reputational losses. We would always advise the safest approach for a company is to regard your cyber security holistically, weaknesses in one area may undermine security implemented elsewhere.
