What is Web Application penetration testing?
Web application penetration testing is a manual security assessment that tests authentication, authorization, business logic, and data handling for vulnerabilities that automated tools structurally miss. Including access control flaws, insecure direct object references, and abuse of application-specific workflows.
Context-driven and realistic. Web application penetration testing that goes beyond OWASP checklists and automated scanners. We analyse application logic, flows, and abuse scenarios to uncover vulnerabilities before real attackers do.
What is the testing scope?
How do we approach testing?
Code Analysis
We combine manual testing with targeted tooling and analyse how the application behaves in practice, not just how it was designed.
Data Testing
We assess how sensitive data is processed, stored, and transmitted, and whether it is adequately protected against misuse or leakage.
Access Control
We test authentication, roles, and permissions to verify whether access can be bypassed or privileges escalated beyond intended limits.
Why do scanners miss the most dangerous vulnerabilities?
Automated scanners detect known CVEs and common misconfigurations. The most impactful vulnerabilities in your application are specific to your code, your logic, and your data model.
Business logic flaws are invisible to scanners
Business logic vulnerabilities occur when an application's own workflows can be abused in ways the developer did not intend. A scanner does not know that your checkout process is supposed to require payment before order confirmation, or that a discount code should only apply once. Manual testers understand context. Scanners do not.
Authentication complexity requires human judgment
Multi-step authentication flows, OAuth implementations, SSO configurations, and session management logic contain abuse scenarios that cannot be expressed in scanner signatures. A tester who understands how the flow is supposed to work can identify every place where it can be broken.
IDOR exposes data across accounts
Insecure Direct Object References allow attackers to access other users' data by manipulating identifiers in requests. Sequential IDs, predictable tokens, and missing authorization checks are the root causes. Scanners miss IDOR almost entirely because identifying the flaw requires understanding the relationship between users, objects, and permissions in context.
What do you receive after the Web App pentesting?
Every web application pentest delivers a complete evidence package. Not just a list of vulnerabilities, but the proof your team and your stakeholders need.
Executive summary
A risk overview for leadership that translates technical findings into business impact. Findings ranked by risk, key vulnerabilities explained in plain language, and clear priorities for remediation investment.
Technical report with OWASP mapping
Full technical detail per finding: description, exploitation proof, OWASP mapping, CVSS score, root cause, and reproduction steps. Structured so your development team can understand and fix each issue independently.
Remediation roadmap
Prioritized fix guidance that distinguishes quick wins from architectural changes. Not just a list of problems but a practical action plan your team can follow in sequence without guesswork.
Retest included
After you fix the findings, we retest to confirm each vulnerability is effectively resolved. You receive written retest confirmation: the documentation your auditors, clients, and insurers expect.
How does web application testing support NIS2?
NIS2 Article 21(1) requires security of network and information systems. Web application testing is the primary validation method for systems that process data or enable business-critical functions.
NIS2 Article 21 covers web application security
NIS2 Article 21(1) requires appropriate technical measures to manage cybersecurity risks, including the security of network and information systems. Web applications that process sensitive data or support critical services fall directly in scope. An annual web application penetration test is the most direct way to demonstrate active validation of these controls.
OWASP-mapped findings for audit documentation
Our deliverable maps each finding to OWASP Top 10 categories and NIS2 requirements. Your compliance team and supervisory authority receive a structured record that your application security is actively tested, vulnerabilities are identified and remediated, and the methodology follows recognized standards.
