Thick Client Security Testing

Find vulnerabilities in client logic and data flows

Attackers target thick client desktops and rich client apps because they frequently manage important business logic and data processing locally. The goal of our Thick Client Security Testing is to find security problems specific to these applications, such as weak communication channels, client-side logic errors, and unsafe local storage.

Experts in Thick Client Security Testing

Our team uses manual testing, protocol analysis, and reverse engineering techniques to find vulnerabilities such as weak authentication, unsecured local storage, and problems with client-server communication. Whether your application is a contemporary rich client platform or a legacy desktop client, we customize our testing to fit its architecture.

Comprehensive Testing Scope for Thick Clients

Reverse Engineering & Decompilation
We analyze binaries to uncover hidden logic, hardcoded secrets, and potential attack vectors. .NET, Java, C++, or Electron - we adapt to your tech stack.
Authentication & Session Handling
We test for weak login mechanisms, insecure session management, and credential storage flaws. Local auth should be just as strong as your backend.
Insecure Local Storage
Sensitive data in plain text? We detect and report unprotected files, registry keys, and config leaks. Your data deserves proper encryption and access control.
Client-Server Communication Analysis
We inspect network protocols, intercept traffic, and test for weak encryption, replay attacks, and logic flaws. All traffic should be tamper-resistant and encrypted.
Tampering & Debugging Protections
We check if the app resists tampering, debugging, memory manipulation, or code injection attempts. Properly hardened apps reduce reverse engineering and runtime abuse.
Third-Party Libraries & Dependencies
We analyze bundled libraries, DLLs, and third-party components for known vulnerabilities and outdated versions. A single vulnerable dependency can quickly expose the entire app.
Clear Reporting & Safe PoCs
You get reproducible steps, clear risk ratings, and developer-friendly remediation guidance. Our reports are built for action, not just audits or compliance.
Business Logic & Privilege Escalation
We simulate real-world abuse scenarios from bypassing user roles to misusing local functionality and business workflows. Security must align with actual use cases.

Specialized Expertise in Thick Client Security

We contribute extensive technical knowledge in examining assembled software, comprehending unique protocols, and identifying security flaws that conventional testing techniques frequently overlook. To find real-world threats including tampering, privilege escalation, insecure storage, and authentication bypasses, our method integrates client-server traffic inspection, static and dynamic analysis, and reverse engineering.

Secure What Runs on the Desktop

Although they manage sensitive data, important business logic, and direct server contacts, thick client apps are frequently disregarded in security initiatives. These systems are carefully evaluated, strengthened, and prepared to resist threats in the real world thanks to our Thick Client Security Testing.

We assist you in addressing security flaws in your app before hackers discover them, regardless of whether it is compiled or hybrid, legacy or current. Join forces with us to improve data security, build trust, and make your desktop apps future-proof.
