Application Penetration Testing

Our talent leads the industry in web application penetration testing, identifying vulnerabilities in a range of programming languages and environments.
From web applications in highly scalable cloud environments to legacy apps in traditional infrastructure, we have helped secure data across the world.

Application Security

Applications are only becoming more relevant. Millions of people depend on web apps to handle their most sensitive information, whether it be for financial planning or medical care. With their growing complexity comes unforeseen security flaws and simple human error. This risk increases as web applications become more interconnected through the linking of APIs. Security researchers find new methods of making these applications bend and break every day.

The best defence is a good offense. By hiring a knowledgeable team of penetration testers to assess your application, you will be made aware of every security hole that could lead to compromised applications and data breaches. This provides you with the foresight needed to fortify your web application and keep your most sensitive assets where they belong.

How We Test


OWASP Web Application Penetration Test

Our proven methodology is based on the industry-recognised Open Web Application Security Project (OWASP) guidelines to assess every aspect of the application’s security – from authentication mechanisms through to business logic and beyond.


Leading Expertise

Our experienced consultants analyse the security of your applications from all user role perspectives. Typical vulnerabilities include SQL injection, Cross Site Scripting, Session fixation, Privilege Escalation and Cross-Site request forgery (CSRF).


Attack Vectors

Depending on the purpose of your application, we determine what threat vectors are applicable. This provides a tailored assessment that applies to your business and relevant threats, not a generic assessment of theoretical risks.


Regular Updates

Regular debriefs will be performed through the assessment. Further to this, a clear report which prioritises the risks relevant risks to your organisation will be provided so you can easily remediate any vulnerabilities.


Complimentary Retesting

We provide complimentary retesting following project completion. This allows you to verify your remediation work has been implemented securely and the identified security risks have been closed.
