Web Application Penetration Testing

Web application penetration testing uses manual and automated approaches to identify security threats or vulnerabilities in your web application. The purpose of this type of pentest is to determine vulnerabilities – possible threats – and help identify ways to mitigate them across the whole application and its component parts (database, source code, back-end services). 

Our team of OSCE and OSCP certified ethical hackers use exploits – like SQL injections and XML External Entity (XXE) injections – to probe ways to gain control of your web application; so that you can prevent others from doing so. In other words… we help you fight fire, with fire.

Delivery Methods

We can provide penetration testing services for your website or application via several delivery methods. You can add penetration testing to your Testing Services Subscription or you could request ad hoc testing for a situation where you don’t test very frequently.  Find out more by clicking each ‘More Info’ button. If you find these all confusing get in touch with us at info@spritecloud.com or via our contact page so we can help you figure out the best solution. 

Remote Testing

Our software testers are very experienced at testing client applications remotely. The COVID-19 virus has forced a lot of organisation to work remotely but fortunately, our testers already have the skills to help remote teams. spriteCloud has been providing testing both remotely and on-site for over ten years. All of our software testing services can be executed remotely.

Ad Hoc Testing

Projects are fixed scope engagements of a predetermined time frame. In other words, we test only what you ask for. Projects can be delivered locally at your office alongside your team or carried out in a remote testing format from our headquarters in Amsterdam and other offices.


Contracting is a method engagement where a tester is contracted to join your organisation to deliver the required testing on a (near-)full-time basis. Contract-based work is typically delivered locally but can also be delivered remotely.

Software Testing Subscription

Our Software Testing Subscription is a monthly recurring package (a Test Stack) made up of a custom mixture of our software testing services. Here you can decide the exact software testing services you want, how much testing you need, and how long you want the subscription. Our Software Testing Subscription allows you to create the best quality products for the best customer experience because it facilitates consistent and high quality testing.

Reported with Calliope Pro

All test results are delivered to you via Calliope Pro, our proprietary test results dashboard. Calliope was designed to make it easy to share, compare, and monitor test results with all stakeholders in one central location. Create a company, upload results, and collaborate more effectively.

Calliope was created for testers, by testers. Give it a try today.

Testing Approaches

To help you ensure the security of your application, we offer three approaches to web application penetration testing that our ethical hackers can take:

black-box penetration testing

Black-box penetration testing

In this perspective of web application penetration testing, the tester is placed in the shoes of a normal internet user with no knowledge of how the application works or access to its source code. This method is closest to what a real hacker would face when trying to penetrate your application.

  • Closest scenarios to what a real hacker would face.
  • Tester acts as normal internet user during pen-testing (with no knowledge of application or source code).

Grey-box penetration testing

A combination of black and clear box testing, with grey box testing testers can create exhaustive tests while remaining close to realistic attack conditions. Testers are given knowledge of the internal workings and functionalities of the applications but without access to the source code. Testers use their knowledge of the system to test the application more thoroughly than if they did not know the architecture of system. This is the most commonly requested form of web application penetration testing.

  • A combination of black and clear box pen-testing.
  • Exhaustive pen-tests while remaining close to realistic attack conditions.
  • Testers are given knowledge of the workings of applications.
  • The tester has no access to the source code.
  • Tests are more thorough than black-box pen-testing.
clear-box testing

Clear-box penetration testing

This web application penetration testing approach requires the tester to have access to the source code of the application. This allows the tester to check the quality of the code within a larger scope normally provided by a developer. While not representative of real-life conditions, it does allow for the more effective securing of applications. This perspective on web application penetration testing makes this the most thorough form of penetration testing.

  • Testers have access to the source code.
  • Testers are able to check the quality of the code.
  • This method is not representative of real-life attack conditions.
  • More effective at securing application due to an in-depth look at source code.
