What Is Web Application Penetration Testing?

Web application penetration testing is a proactive way to uncover vulnerabilities in your applications that can lead to unauthorized access and data exposure. Depending on the engagement, pen testing can be used to assess the architecture, design, configuration and/or implementation of your apps. A pen test will look for critical risks in apps developed in-house or those from third party vendors, including injection flaws, authentication weaknesses, security misconfigurations and flaws in application logic.

OWASP Top 10 and Beyond: Web App Pen Testing Scalable to Your Needs

Kroll’s approach to web application pen testing starts with an understanding of the context of your apps: the business case and logic headlining the show. We take a manual, human-directed approach to uncover issues that scanners and tools alone can’t find. 

Our team provides coverage for OWASP Top 10 and digs deeper to understand your risk to develop a program customized to your priorities. From day one, you’ll work with our in-house team, including technical program managers and project leads who keep the testing schedule on time and on budget, and who can support in scaling and adjusting scope.

Context and quality are crucial for us. At the end of each testing phase, our team delivers a final assessment that has gone through QA, vetting and technical review to ensure findings have been validated and to give you a clear plan for action.

Agile Pen Testing: A New Paradigm for Application Security

Agile pen testing, or continuous pen testing, is a method for integrating regular testing into your software development lifecycle (SDLC), rather than testing at infrequent points in time.

Whereas, traditional pen testing impacts product release cycles, Agile pen testing works with your release schedule to ensure that new features are secure and don’t translate into risk for your customers.
