Desktop Application Penetration Testing
Identify vulnerabilities in your desktop applications before attackers do.
What this assessment covers.
Desktop applications handle sensitive data and often run with elevated privileges, making them an attractive target for attackers. DERISK’s Desktop Application Penetration Testing service provides a deep, expert-led assessment of your desktop application’s security posture, simulating real-world attacker techniques to uncover vulnerabilities that automated scanning alone cannot detect.
Our assessments go beyond surface-level checks. We analyse authentication flows, local data storage, memory handling, inter-process communication, update mechanisms, and business logic flaws that could allow privilege escalation, data exposure, or unauthorised access. Every finding is manually validated to ensure zero false positives and delivered with clear, developer-ready remediation guidance.
How we test.
A structured, expert-led methodology from initial reconnaissance through to real-time reporting and remediation guidance.
- 01
Reconnaissance and mapping of the application surface
We begin by mapping your desktop application’s full attack surface — installed components, network communication, local storage, and hidden functionality — to understand how the app behaves and where it might be vulnerable.
- 02
Authentication, session, and access control testing
We rigorously test login mechanisms, session tokens, and role-based access controls to ensure users can’t escalate privileges, hijack sessions, or access data they shouldn’t see.
- 03
Local storage and memory analysis
We examine how the application stores sensitive data locally and in memory, identifying credentials, tokens, or confidential information that could be extracted by an attacker or another process.
- 04
Inter-process communication and update mechanism testing
We probe IPC channels, custom protocol handlers, and auto-update mechanisms for injection, hijacking, and man-in-the-middle risks that could allow code execution or tampering.
- 05
Real-time findings published to the DERISK PTaaS portal
As vulnerabilities are confirmed, they are immediately published to the PTaaS portal with proof-of-concept evidence so your team can start remediation without waiting for the final report.
- 06
Report and recommendations with remediation guidance
You receive a comprehensive report with risk-rated findings, CVSS scores, and developer-ready remediation steps prioritised by business impact.

Desktop App Pentest questions.
What is tested in a desktop application assessment?
Local data storage and credential handling, binary protections and tampering resistance, inter-process communication, privilege and installer behaviour, update mechanisms, and the server-side services the client depends on.
Why do thick clients need separate testing?
Desktop applications run on hardware the attacker controls. Assumptions that hold in a browser — that the client cannot be modified, that validation happens before the request — simply do not apply, and that is where the findings are.
What do you need to begin?
An installer or build, test credentials for each role, and details of the backend services in scope. Source code is optional and deepens coverage.
How quickly will we see results?
Initial confirmed findings appear on the DERISK platform within 8 hours of kickoff, critical issues are validated and published within 2 hours of discovery, remediation retests complete within 24 hours, and the full report lands within 2 business days of engagement close.
