Thick Client Pentesting

Desktop applications can contain sensitive business logic, communicate with backend systems, and handle valuable information outside the traditional browser environment. Our Thick Client Penetration Testing service examines these applications for weaknesses that could be exploited through the application, its local environment, or its connections to backend services.

We assess Windows and other desktop-based applications, including application functionality, local data storage, authentication, configuration, communication with backend systems, access controls, and interactions with supporting services.

The engagement produces a detailed report with confirmed vulnerabilities, affected application components, evidence, severity, business impact, and prioritized remediation recommendations. An executive summary provides a clear overview of the risks for business stakeholders.

Testing helps organizations identify weaknesses that traditional web or network testing may overlook. It strengthens desktop applications, protects locally handled information, and helps prevent attackers from using vulnerable client software as a pathway into critical backend systems.
