A powerful tool for ensuring robust web application security
Web app penetration testing stress-tests the security of web applications with the purpose of finding vulnerabilities before they are exploited.
Web applications are increasingly used to handle sensitive data and are critical for effective business operations. Simulating the activities of an attacker is the best way to find and fix vulnerabilities before business security is compromised.

We guide you through the entire process
We work with you at every step of your cyber security journey.
Before any testing takes place, we consult with your team and scope the engagement. We exclude any applications you do not want to be tested, and define areas of particular focus, ensuring all parties are aware of the requirements.
Once the scope is agreed upon, the test is scheduled and key points of contact are designated.

Uncover vulnerabilities before they become an issue
Web application security testing proactively identifies security vulnerabilities in web applications.
Security vulnerabilities can exist in any part of the application, from the code to the user interface. The top web application security risks are:
- Broken access controls: Access controls ensure users cannot act outside of their permissions. Failure of these controls can lead to unauthorised access to sensitive data.
- Cryptographic failures: This covers a broad range of issues with data encryption in storage and transmission. Unsecured data is easier to access and expose.
- Injection: A vulnerability where user input is incorrectly handled and used to execute unintended actions. This can allow an attacker access to sensitive data or control of the web application.

Our web application penetration testing service simulates real-world attacks
Most malicious actors attempt to force access to web applications externally.
From a remote external location, we attempt to compromise your web application through a black box pen test. For example, we test if we can access the database behind the web apps in a way we shouldn’t be able to. We attempt to view, modify or delete data without the appropriate permissions.

Vulnerabilities in your web server could compromise your IT infrastructure
Your web server is a critical part of your IT infrastructure and should be secure against any attack.
We simulate a real-world attack on your server by attempting to install rogue code that would be executed in visitors’ web browsers to your website, potentially compromising them.
We then try to take control of the server hosting the website, which could give us the ability to delete or copy the entire site and all the data, or even connect to other machines it is attached to.
