Web Application Penetration Testing

Web applications are among the primary targets for cyberattacks.

A Web Application Penetration Test thoroughly examines the security posture of your application—from internal logic and source code to interfaces and communication with users and external systems.

Its purpose is to identify vulnerabilities, misconfigurations, privilege issues, or any weaknesses that could allow unauthorized access or data leakage.

Expose Security Weaknesses with a Web Application Penetration Test

Compromised web applications can lead to severe consequences—user data theft, account takeover, information leakage, or injection of malicious code.

A Web Application Penetration Test helps identify these weaknesses before attackers exploit them.

At RedEntry, we provide in-depth penetration testing for web applications based on OWASP methodologies and additional international security standards, ensuring your system meets the highest level of protection.

Our testing combines automated tools with extensive manual analysis to identify even subtle vulnerabilities—those often overlooked by organizations but capable of causing real damage.

Examples of critical vulnerabilities our testing can uncover:

What We Offer

We provide a comprehensive approach to Web Application Penetration Testing aimed at identifying and addressing security vulnerabilities before malicious actors can exploit them.

RedEntry’s experts deliver a realistic, risk-based evaluation of your applications, tailored to your organization’s business and technological needs.

We combine proven cybersecurity methodologies with personalized assessment, ensuring each test is designed according to your environment, architecture, and unique risk profile.

Alongside industry-standard methods, we apply a focused and precise approach to eliminate unnecessary “noise” and highlight the findings that truly matter.

This ensures you receive the most accurate, actionable insights for securing your application—while also maintaining full coverage of all relevant security checks.

The result: practical insights, prioritized remediation recommendations, and a testing process that delivers real value to your organization.

We contractually guarantee that our reports meet the requirements of leading standards such as ISO, SOC 2, GDPR, and more.

Chief Information Security Officer (CISO) at CHEQ

“We worked with RedEntry on a large-scale Web Application Penetration Test, and the team exceeded all our expectations.

Even before the project began, they invested time in understanding our needs, analyzed the systems in depth, and presented a clear and accurate picture of the risks.
The tests were conducted thoroughly, transparently, and precisely—with detailed reports and practical recommendations we could apply immediately.

I highly recommend RedEntry to any organization that wants to ensure its security posture meets the highest standards.”

Benefits of Web Application Penetration Testing

Web penetration tests provide your organization not only with a security snapshot but with real business value—through early risk detection, compliance alignment, and continuous security improvement.

Real-time vulnerability identification

Deep analysis of code and system architecture to expose critical weaknesses

Regulatory & compliance requirements

Including ISO 27001, PCI DSS, SOC 2, GDPR and more

Prevent data breaches & account takeovers

Simulated real-world attacks from an adversarial perspective

Increase user & customer trust

Strengthen reputation and avoid damaging business impact

Types of Web Application Penetration Tests

We offer three primary types of Web Application Penetration Tests, varying in the amount of information provided to the testers. Each type offers a unique perspective and contributes to a comprehensive understanding of your application’s security posture.

Black Box Testing

Testers perform the assessment without any prior knowledge of the system. This approach simulates a real-world cyberattack from an external attacker, identifying the exploitable weaknesses they might encounter.

Execution time: up to 14 business days

Grey Box Testing
Most Popular

Testers receive partial access or limited information about the system. This method enables effective focus on critical areas, evaluation of user permissions, and analysis of complex data flows—while maintaining an attacker’s mindset.

Execution time: up to 14 business days

White Box Testing

Testers operate with full access to the source code, databases, and administrative interfaces. This provides deep insight into application logic, internal failures, and vulnerabilities that cannot be detected through external-only testing.

Execution time: up to 18 business days

Tools We Use

Our Approach to
Web Application Penetration Testing

01

Preparation & Scoping

We hold a kickoff meeting with key stakeholders, review the system architecture, and define testing boundaries and objectives.
Access to development or production environments is provided as needed, including IP ranges, test users, and relevant API endpoints.

02

Mapping & Information Gathering

We perform technological fingerprinting, identify entry points, key API endpoints, and configuration details that may indicate potential risks.

This phase includes automated scanning combined with manual exploration to build a structured target list for controlled exploitation attempts.

03

Controlled Exploitation

Testers simulate realistic attack scenarios based on the testing plan.
This includes SQL Injection, XSS, authorization testing, input validation checks, business logic abuse, and API security testing.
Every action is documented for reproducibility and assessment.

04

Findings Report & Remediation Guidance

We convert technical findings into clear, actionable insights.
The report includes risk ratings, technical documentation and screenshots, code-level and configuration-level remediation recommendations, and a prioritized action plan based on business impact.

We also support the remediation process and provide a re-test with a final compliance certificate.
