Web Application Penetration Testing

Secure Your Web Apps Before Attackers Exploit Them

Since the web is the main entrance to your business, it is very likely that attackers are trying to break in. At Orasec, our web application penetration testing service is a method by which we install the same environment as the real attackers so they can try and see which points of authentication can be bypassed, which business logic is faulty, which means of injection can be abused, and what security issues are present that the commonly used automated scanners may not detect. Therefore, you can guard your digital resources by having a set of useful and clear instructions for fixing the problems complete with a list of priorities, along with the specialization and the trustworthiness of the certified web application penetration testers. In addition, by keeping the attackers at bay and having an understanding of your security level, you can make the most out of the situation.

Our Web Application Penetration Testing Services

Orasec provides comprehensive web application penetration testing services to identify vulnerabilities and secure every layer of your web ecosystem. Our sub-services include:

Authentication & Session Management Testing

Evaluate login flows, session handling, password resets, and multi factor authentication to prevent account takeover and session hijacking.

Input Validation & Injection Testing

Test all user inputs for SQL, NoSQL, command, and template injections to secure backend databases and application logic.

Business Logic & Workflow Testing

Analyze multi step processes, financial workflows, and critical operations to detect logic flaws that automated scanners miss.

Access Control & Authorization Testing

Verify role based access, horizontal and vertical privilege enforcement, and API endpoint authorization to prevent unauthorized data access.

API Security Assessment

Test REST, GraphQL, and gRPC APIs for authentication, authorization, BOLA/BFLA vulnerabilities, and sensitive data exposure.

Web Server & Infrastructure Testing

Assess web servers, hosting environments, and integrations for misconfigurations, outdated software, and exposure risks.

Mobile & Web App Integration Testing

Evaluate iOS/Android web app endpoints and backend integrations to ensure secure communication and data handling.

Automated & Manual Hybrid Testing

Combine automated scans with expert manual testing to cover known vulnerabilities, hidden flaws, and complex attack paths.

OWASP Top 10 & ASVS Compliance Testing

Map findings to OWASP Top 10 and ASVS Level 2 standards for compliance and actionable remediation guidance.

Continuous Web App Security Testing (Optional)

Ongoing monitoring and periodic testing to detect new vulnerabilities as applications evolve or receive updates.

Every Feature Is an Attack Vector

Web applications are the primary entry point for data breaches. They handle authentication, process payments, store sensitive data, and integrate with backend systems. A single vulnerability can expose your entire organization.

Think Like an Attacker, Test Like One

Secure Your Web Applications Before Attackers Do

Every feature of your web application is a potential attack vector. Every input field could be exploited, and every authentication flow is a possible bypass. Orasec’s web application penetration testing services simulate real world attacks, uncovering vulnerabilities, injection points, and misconfigurations before they become security incidents.

Black Box, Grey Box, and White Box Web Application Testing

Different types of web application testing require different initial conditions. OraSec conducts black box testings that simulate an external attacker who has no prior knowledge at all. The grey box testing enables the testers to work with few credentials and the architectural context. In the white box testing, the testers get the source code, documentation and the deepest vulnerability can be covered. The right strategy depends on your risk exposure, development phase, and compliance requirements and our staff will advise you on the most suitable testing model in your setting.

Web Application Penetration Testing for SaaS, Fintech, and ecommerce

Handling financial transactions, customer data, or subscription access through web applications involves risks that are inherently different from those associated with informational sites. Our testers possess the knowledge and skills to evaluate SaaS platforms to identify multi tenant access control failures, to check fintech applications for payment logic abuse and transaction manipulation, and to inspect ecommerce platforms for price tampering, account takeover chains, and checkout bypass vulnerabilities. We are guided by industry context in our testing methodology it's not only about what we test but also how we test.

How Attackers Exploit Web Applications

SQL injection for database access and data extraction

Authentication bypass through session handling flaws

Insecure Direct Object References (IDOR) to access other users' data

Server Side Request Forgery (SSRF) to reach internal systems

Business logic abuse to manipulate pricing, permissions, or workflows

Cross Site Scripting (XSS) for session hijacking and credential theft

Deserialization attacks for remote code execution

Beyond the OWASP Top 10

Manual Web Application Pen Testing to Find Real Risks

Automated scanners can identify common vulnerabilities, but Orasec’s web application penetration testing goes further. We examine your web apps through an attacker’s lens, testing business logic, authentication flows, authorization, and multi step processes that scanners miss.

Manual Testing Focus:

  • Session management flaws that allow hijacking or reuse
  • Multi step process bypasses and chained actions
  • Role escalation paths and privilege abuse
  • Second order injection attacks triggered later in the workflow
  • Business logic flaws requiring contextual understanding
  • Authentication bypass via parameter manipulation
  • Authorization failures dependent on valid sessions
  • Race conditions in payments, inventory, or transactional systems
  • Chained vulnerabilities combining multiple low severity issues

Orasec’s approach ensures that your web application is not just OWASP compliant, but resilient against real world attacks targeting your unique business logic, workflows, and user interactions.

Compliance Ready Web Application Security

Ensure your applications meet OWASP Top 10, ASVS Level 2, PCI DSS, ISO 27001, and GDPR standards. Orasec provides actionable reports with remediation guidance.

Our Web Application Penetration Testing Methodology

Structured Approach to Securing Your Web Applications

Orasec’s web application penetration testing services are based on a thorough methodology that helps reveal vulnerabilities and harden your applications against attacks from the outside. At each stage, the attacker's perspective is taken to probe, exploit, and find ways to break into your web defenses.

  1. 1

    Mapping

    List down all the endpoints, parameters, APIs, and authentication flows.

    Understanding the whole scenario of your application's web interfaces is crucial for recognizing potential attack surfaces.

  2. 2

    Authentication Testing

    Analyze login means, session handling, and password recovery options at depth.

    Uncover tracing routes to account takeovers and detecting lapses in authentication are the basic results of this phase.

  3. 3

    Authorization Testing

    Ensure proper functioning of permission systems by simulating different user roles.

    Unmasking privilege escalation opportunities and unauthorized access risks are the hallmarks of this activity.

  4. 4

    Injection Testing

    Evaluate all data entry nodes for exposure to SQL, NoSQL, command, and template injection attacks.

    One major outcome of injection testing is pinpointing a variety of ways that an attacker might gain control of the backend system.

  5. 5

    Business Logic Testing

    Evaluate the sequence of actions and multi step operations for potential misuse or exploitation by a malicious user.

    Business logic testing is a key activity to uncover issues that might lead to loss of financial data, disclosure of sensitive information, or disruption of operational integrity.

Orasec combines manual testing expertise with advanced penetration techniques to ensure your web applications are secure against both common vulnerabilities and complex, real world attack scenarios.
