How does Web App Pen Testing work?

Web App Penetration Testing works by simulating cyberattacks against web applications to identify vulnerabilities and weaknesses in their security defences. Web app pen-testing is mostly manual testing. Through thorough testing and analysis, the goal is to assess the resilience of web applications against potential threats and provide recommendations for remediation. Best performed with pen-testers who have extensive experience in development, like our team here! We test against the OWASP guidelines, and not just the 'top 10'.
