Web Application Penetration Testing

Web applications play an increasingly important part in our daily lives. Individuals, companies and organisations rely on them to carry out a wide range of tasks and processes. 

With this increased online activity comes an increased threat of cyber-crime. One way this can be addressed is through Web App pen testing.

What is Web App Pen Testing and Why is it Required?

Web application penetration testing is a simulated attack on a web application to identify vulnerabilities in the software. The aim of the testing is to expose any weaknesses in the application’s security system and help improve its resilience against potential cyber-attacks.

Web security penetration testing differs from mobile app testing in that it is targeted at potential vulnerabilities in web applications accessed through a web browser rather than applications installed on mobile devices.

What are the methods?

Web app testing can be carried out using a variety of methods, such as:

All of these methods can identify any potential vulnerabilities in an application’s security system.

Web application security penetration testing is essential if a company is to avoid a range of negative consequences such as data loss or theft and reduced revenue. Compromised security can also have a detrimental impact on an organisation’s reputation.

Certified by CREST and Offensive Security, our qualified testers employ real-world hacking techniques to uncover profound insights.

How Does Web App Pen Testing Differ from Bug Bounty?

Web app penetration testing is a proactive approach to identifying vulnerabilities in a web application, whereas bug bounty programs are reactive and rely on external individuals to report vulnerabilities.

It was a pleasure working with the Equilibrium team - they were very understanding of our needs, worked very well with my team, and most importantly were very patient and understanding of the limitations of my team to provide the information required when needed due to other priorities.
