Protecting Your Digital Assets with Expert Penetration Testing

FQRS specializes in vulnerability assessment and penetration testing for mobile applications, web applications, and APIs. We help protect your digital assets from various cyber threats.

Every FQRS engagement includes three commitments: a free remediation re-test within 90 days, a version-locked test completion certificate documenting exactly what was tested, and Critical Miss Protection — if we miss a proven Critical (CVSS 9.0+) vulnerability in your tested build, you choose either a 100% fee refund or a free full re-engagement.

Submit a detailed Proof of Concept (POC) demonstrating the missed Critical (CVSS 9.0+) vulnerability within 90 days of your completion certificate. We will validate it against our version records. If confirmed as an FQRS oversight, you may choose a 100% fee refund or a free full re-engagement — processed within 7 working days.

No. Protection applies only to the exact version documented on your FQRS completion certificate. Any vulnerabilities from code changes, new features, or infrastructure updates made after testing are not covered — we recommend using the included free remediation re-test after you apply fixes.

Yes. Claims must be submitted within 90 days of your completion certificate date. The free remediation re-test is also available within the same 90-day window after your original report is delivered.

Yes. The FQRS Assurance Package — including the free re-test, version certificate, and Critical Miss Protection — applies to all penetration testing engagements: API-only, mobile application, and web application testing. Full application tests cover associated APIs and client-side data handling within scope.

Our core philosophy is to test your applications from the perspective of an external, public user or a determined attacker. This means that, for publicly accessible assets and functionalities (e.g., publicly available websites, mobile apps downloadable from app stores where account registration is open), we typically require nothing more than a signed contract. We pride ourselves on independently understanding and exploring your application's business flow to uncover vulnerabilities that might be missed by internal teams.

However, for specific scenarios such as testing features behind a login where public registration is not available, or for non-public API endpoints, we would arrange with you to gain the necessary access. Our goal is always to minimize disruption to your team while maximizing the effectiveness of our assessment.

After completing our comprehensive penetration testing, FQRS provides a detailed, actionable report. This report includes a clear description of each identified vulnerability, its severity (based on industry standards like CVSS), potential impact, and step-by-step instructions for remediation. We offer a debriefing session to walk through the findings and answer any questions. While our primary service is vulnerability identification, we are available for follow-up discussions and re-testing to help validate that vulnerabilities have been successfully remediated.

We conduct our testing from the perspective of a public user, without any internal knowledge or engagement from your team. We believe that true security can only be tested by understanding your application's business flow as an external consumer and then performing a real-world assessment. As independent engineers, we first thoroughly understand the application as a consumer to gain full context. After this deep understanding, we then perform real-world testing to identify critical vulnerabilities that might be missed by internal teams, thus preventing potential financial and reputational damage.

In most companies, a product is developed by multiple teams, and many developers work on a specific task, module, or feature without having the full context of the application. This makes it harder for them to identify broader vulnerabilities. However, each module, service, or feature can be interdependent, and a vulnerability in one area can affect others. Since most attacks are carried out through publicly available assets, such as public APIs, and a consumer interacts with these same assets, our approach gives us crucial context into why and how specific APIs are used and consumed by both users and the application's frontend, allowing for a more comprehensive and realistic assessment.

Yes, apart from security vulnerabilities, we also report on any wrong practices that lead to unnecessary financial loss for companies. For example, if we identify duplicated actions like double invoice creation or sending multiple OTPs for a single transaction, these lead to unnecessary costs. While such issues might be outside the strict scope of security vulnerabilities, we still report them as part of our commitment to improving overall application quality and efficiency for our clients.

Yes, FQRS offers flexible reporting options tailored to your contract. While some clients prefer reports focused on high-impact vulnerabilities (based on severity and criticality), we can also provide comprehensive reports covering all API endpoints and flows. We meticulously scan and perform automated and manual tests on each API endpoint to generate a detailed report, even if no vulnerabilities are found.

Yes, regular penetration testing is a critical component of ISO 27001, an internationally recognized standard for information security management systems. Our comprehensive testing helps organizations align with industry best practices and maintain compliance. Absolutely, we also offer options to perform API security tests at regular intervals. This ensures that even as new APIs are added or removed, or existing ones are modified, your security posture remains continuously validated. Regular third-party assessments are often a requirement for certifications like ISO 27001, and we provide updated reports reflecting the latest state of your application's security.

Our unique value proposition lies in our dual focus on critical security vulnerabilities and overlooked operational flaws. We don't just find typical security issues; we also identify and report on "wrong practices" that lead to unnecessary financial losses, such as duplicate invoice creation or redundant OTPs. By immersing ourselves in your application's flow like a consumer, we gain a comprehensive understanding that allows us to spot both technical vulnerabilities and inefficient processes that impact your bottom line. This holistic approach ensures a more secure and cost-effective digital operation for your business.

Based on our extensive experience across various platforms, we commonly identify high-impact vulnerabilities such as account takeover (e.g., authentication bypasses, session management flaws), coin crediting vulnerabilities (e.g., unauthorized virtual currency manipulation, free coin generation), bulk account creation flaws (e.g., registration bypasses leading to bot networks), and payment bypasses (e.g., payment gateway manipulation, premium feature access without payment).
