Our web app penetration testing services

Real-time protection

Authenticated tests

Analyze the security of your web app from a user perspective. Auditing the admin portal of your web application will reveal vulnerabilities including SQL injection, session fixation, privilege escalation and cross-site request forgery (CSRF).

Seamless security

Unauthenticated tests

This is the most common type of web application test. Our penetration testers will identify vulnerabilities in publicly-visible networks that could be exploited by users who do not have access credentials.

Rapid time-to-value

API pen tests

If your web app has an API then it is vital to check this for vulnerabilities as part of your penetration test. Our experts will work with you to ensure that this is covered as part of your test scope where applicable.


Identify web app security vulnerabilities

Identify web app security vulnerabilities

We will carefully analyze all aspects of your web app with advanced tools and manual expertise.

Your CREST-certified penetration tester will search for and expose a range of security weaknesses, including:

  • Vulnerabilities and misconfigurations
  • All critical security risks, including the OWASP Top 10
  • Insecure app functionality
  • Security design issues

If any web app vulnerabilities are found, your tester will provide details about how they were exploited, including actionable remediation advice to help you fix them.

Frequently Asked Questions

Whilst all web app penetration tests have the same goal of uncovering security weaknesses, there are different areas to consider:

  • Authenticated tests analyze the security of your web app from a privileged user perspective.
  • Unauthenticated tests mean that our penetration testers hunt for security weaknesses without access to user credentials.
  • API tests are a vital component to include if your web application has an API. Penetration testing a web app’s API uses slightly different tools, and techniques. It is often covered separately from the scope of a web app test.

We usually recommend a blend of all three testing types to get the most value from your penetration testing engagement and understand all of the possible risks to your web application.

To scope a web application penetration test and for you to get the most value out of it, the tester would first need to establish the rules of engagement and what the end goal is for the web app pen test.

A scope would include gathering as much information about the target as possible, identifying all the web applications that require testing, and whether the test will be authenticated or unauthenticated.

Your penetration tester will provide you with a detailed list of all vulnerabilities found during your web app pen test, including how they could be exploited.

Your web application pen test results will be hosted in our secure Defense.com™ platform and automatically sorted in order of criticality. You’ll then have a prioritized list of vulnerabilities to fix, along with actionable advice to help you remediate each threat.

The duration of a web application penetration test will be determined by the size and complexity of the scope. For example, the greater the number of applications to test, the longer the web app pen test will take. Once the pen tester has understood the business, the number of applications to be assessed, and the desired outcomes of the web app pen test, they will be able to assign a timeframe for the duration of the test.
