SECURE MISSION CRITICAL APPS
THICK CLIENT PENETRATION TESTING
Thick client applications have become increasingly attractive targets for hackers in today’s hybrid infrastructure architecture models. Their extensive use across organizations, often involving critical and sensitive data processing, presents significant security challenges. Thick Client penetration testing is an ethical hacking security assessment carried out to uncover vulnerabilities in the thick client software application, network traffic, and backend interface and prioritize remediation efforts to mitigate cyber risks.

SECURE YOUR THICK CLIENTS
What is Thick Client Penetration Testing?
Thick client application testing is generally more complicated and customized, involves both local and server-side processing, and often uses proprietary protocols for communication aimed at detecting and identifying loopholes and vulnerabilities before they are exploited for malicious gain. Simple automated scanning is not sufficient and testing thick client applications requires a lot of patience and a methodical approach.
At Secragon, we specialize in predominantly manual penetration tests, conducted by experienced ethical hackers. Along with leveraging industry standard methodologies to ensure a thorough security assessment is conducted under safe and controlled conditions, our expert team utilizes an advanced mix of public and in-house developed exploits and in-depth analysis to discover complex vulnerabilities not yet published and often, not yet discovered. The objective is to penetrate the target application, document the threat profile, and provide a clear risk mitigation strategy.
We don’t just point out security holes; we help you solve them and comply with standards and regulations.
Identifies security weaknesses within the client application, network communication, and backend interactions.
Ensures that critical and confidential data processed by the application is safeguarded against unauthorized access or breaches.
Helps in meeting industry-specific security regulations and standards, reducing the risk of legal and compliance issues.
Builds confidence among users and stakeholders by demonstrating a commitment to security, especially in environments with sensitive data transactions.
Avoids the costly consequences of security breaches, including financial losses, customer trust erosion, and damage to brand reputation.
Keeps pace with the changing landscape of cybersecurity threats, particularly important with the increasing sophistication of hacker techniques.
Why Conduct a Thick Client Penetration Test?
Conducting a Thick Client Penetration Test is vital to ensure the security and integrity of desktop-based applications, particularly as they become more susceptible to sophisticated cyber threats in today’s hybrid work environments.
PROTECT AGAINST THE LATEST THREATS
When Should You Perform Thick
Client Application Penetration Testing?
Penetration Testing should be performed as frequently as required by the organizational security policy. In addition to the regular schedule, penetration testing is particularly advisable in the following instances:
Before
Launching a New Application
To identify and rectify any security vulnerabilities before the application is deployed to users.
Following a
Security Breach or Incident
To thoroughly understand the scope of a breach and to ensure all vulnerabilities are addressed post-incident.
After Significant
Updates or Changes
To ensure new or modified features haven’t introduced vulnerabilities.
In Response to
New Threats or Vulnerabilities
Whenever new threats that could potentially affect the application are identified.
Regularly as
Part of Security Audits
Conduct these tests periodically, such as annually, as part of an ongoing security maintenance program.
When Integrating with
New Systems or Technologies
To ensure that new integrations or technology upgrades do not introduce security flaws.

What Will Be Assessed During a Thick Client Penetration Test?
During a Thick Client Penetration Test, several key areas are typically assessed to ensure the security of the application:
Local Data Storage
and Encryption
Examining how data is stored locally and whether encryption methods are used effectively to protect sensitive information.
Communication with
Server and Network
Security
Assessing the security of data transmission between the client and the server, including the inspection of network protocols and encryption used.
Authentication and
Authorization Mechanisms
Testing the robustness of mechanisms for
user verification and access control within
the application.
Error Handling and
Logging
Evaluating how the application handles errors and whether it inadvertently exposes sensitive information or logs in an insecure manner.
Input
Validation
Evaluating the security of data in transit, focusing on the implementation of SSL/TLS encryption.
Dependency
Security
Reviewing third-party libraries and dependencies used in the application for known vulnerabilities.

Frequently Asked Questions
Couldn’t find the information you were looking for?
To prepare for a thick client penetration test, ensure you have gathered comprehensive documentation on the application’s architecture, arrange access to a testing environment (if needed), and appoint a dedicated point of contact to facilitate smooth communication with our testing team. We work closely with our clients to understand these perspectives to accurately scope and complete API penetration tests.
A test can typically be scheduled within 5-10 days following a scoping call. If you need an urgent one, reach out to us immediately—we’re ready to assist. Connect with us now to secure your spot!
Vulnerability scans are automated and look for known vulnerabilities, while penetration testing is a more comprehensive approach that involves simulating actual cyberattacks to find vulnerabilities.
In most cases, no specific access is required for the test, as the goal is to replicate a real-world attack scenario. However, depending on the features available on the thick client or the specific goals of the test, some level of access or permissions may be necessary. This will be determined in collaboration with our team, ensuring that the test is tailored to your application and security objectives while maintaining a realistic approach.
Thick Client penetration testing is an integral part of your overall application security strategy, more particularly for mission-critical apps, as it helps you identify & fix vulnerabilities to ensure your end users have a secure environment to share sensitive data and conduct their daily operations.
Client data protection is our priority. We use non-destructive methods during our assessments and maintain strict confidentiality.
