WEB APPLICATION PENETRATION TESTING
Identify and remediate your web app vulnerabilities
Certified testers attack your web apps the way real adversaries do, then Penarc turns every finding into a clear fix plan.
What is web application penetration testing?
Web application penetration testing is a controlled attack on your website or web app by security experts to find exploitable flaws, such as broken access control, injection and authentication weaknesses, before attackers do. Unlike automated scanners, testers also check business logic and chained attacks by hand.
Your web apps are the front door. We test the locks.
Customer portals, dashboards and admin panels hold your most sensitive data. Web application pentesting finds the flaws attackers can exploit and proves each one with evidence, so your team knows exactly what to fix first.
