Penetration Testing
Secure Your Thick Client,
Protect Your Data Where It Lives.
Thick Client Penetration Tests identifies unique and critical vulnerabilities found in applications that run locally on a user’s machine. Unlike web applications that primarily process data on a server, thick clients perform a significant amount of processing and data storage on the client side, creating a larger and more complex attack surface. We perform our tests based on industry recognised standards, OWASP Top 10 Desktop Application Security Risks which covers the following risks:
Input Injections
Broken Authentication & Session Management
Sensitive Data Exposure
Improper Cryptography Usage
Improper Authorisation
Security Misconfiguration
Insecure Communication
Poor Code Quality
Using Components with Known Vulnerabilities
Insufficient Logging & Monitoring

Hardening Your Thick Client Applications Using Proven Security Frameworks
We perform thick-client application penetration testing based on industry recognised standards, OWASP Top 10 Desktop Application Security Risks.
Our testing uses a combination of tools, techniques, and custom approaches to determine whether it is possible for an attacker to:
Bypass Authentication
Circumvent authentication and authorisation mechanisms.
Privilege Escalation
Perform vertical or horizontal privilege escalation.
Access Control Exploitation
Bypass access controls or application restrictions.
Unauthorized Data Access
Access or modify unauthorised data.
Cryptographic Weaknesses Exploitation
Break or analyse cryptography used within user accessible components.
Actionable Recommendations You Can Bring To Stakeholders
We deliver comprehensive, cryptographically signed penetration testing reports that are both verifiable and tamper-proof. Each report includes detailed vulnerability backgrounds, clear impact assessments, and actionable recommendations. And because security is a global concern, our reports are available in 113 languages—ensuring your cross-border teams are always in the know.
Compliance Verification Reporting
The report clearly shows the specific standards the app complies to.
