Desktop applications require a different level of security testing
Unlike web applications, desktop applications interact directly with operating systems, local files, memory, installers, and device resources, creating unique attack surfaces that automated scanners often miss. Rhymetec performs comprehensive manual penetration testing to evaluate how your application handles authentication, stores sensitive information, communicates with backend services, and protects against client-side attacks.
A proven methodology for secure desktop applications
Every engagement follows a structured, risk-focused approach tailored to your application, platform, and deployment model.
Planning and preparation
Define scope, review application architecture, establish testing objectives, and gather installers, credentials, licensing requirements, and supporting documentation.
Environment setup and discovery
Our team installs and analyzes the application, identifying entry points, local resources, backend communications, user workflows, and operating system interactions to establish the application's attack surface.
Penetration testing and exploitation
Using a combination of manual testing and specialized security tools, we evaluate authentication, authorization, local data storage, encryption, installer security, binary protections, runtime behavior, operating system integrations, and application-triggered backend requests. Where appropriate, both black box and grey box testing methodologies are supported.
Analysis and reporting
Every validated finding is documented with business impact, technical evidence, remediation guidance, and developer-ready recommendations. Critical findings are communicated immediately so remediation can begin without waiting for the final report.
Security insights that support every deployment
Desktop application assessments focus on installed client software and application-triggered backend communications.

What is desktop application penetration testing?
Desktop application penetration testing evaluates the security of installed software running on Windows, macOS, or other supported operating systems. Rhymetec simulates realistic attack scenarios to identify vulnerabilities in authentication, local storage, application binaries, operating system integrations, and backend communications that could allow unauthorized access or data exposure.
Do you perform black box and grey box testing?
Yes. Black box testing simulates an external attacker with little or no prior knowledge of the application, while grey box testing includes limited access such as user credentials or multiple permission levels. The appropriate approach depends on your objectives and application architecture.
What's the difference between desktop application testing and web application testing?
Desktop application testing focuses on software installed directly on user devices, including installers, binaries, local files, operating system permissions, runtime behavior, and application-generated network traffic. Web application testing evaluates browser-based applications and server-side functionality. Because each has different attack surfaces, they require different testing methodologies.
What types of vulnerabilities can desktop application testing identify?
Our assessments commonly uncover insecure local storage, authentication and authorization weaknesses, privilege escalation opportunities, insecure installer configurations, DLL hijacking risks, hardcoded secrets, weak encryption, insecure backend communications, weak
or bypassable binary protections, and other client-side security issues that could impact your application or users.
