Web Application Penetration Testing

Web applications are one of the most targeted assets in today’s threat landscape. At Patron Cyber Security, we specialize in manual, in-depth web application penetration testing to uncover the vulnerabilities scanners miss.

Our assessments go beyond automated tools to simulate real-world attacks, testing for everything from OWASP Top 10 issues to complex business logic flaws and insecure APIs.
