Web Application Penetration Testing: Find and Fix Vulnerabilities Before Attackers Exploit Them

Protect your web apps from data breaches, fraud, and compliance risks — with penetration testing based on the OWASP Testing Guide (WSTG) and interactive security training for your team.

Why Web Application Security Is Critical

Web applications are the primary target of cyberattacks — with consequences such as:

✅ Data theft (e.g., SQL Injection, Broken Authentication)
✅ Financial losses (e.g., API abuse, session hijacking)
✅ Regulatory penalties (GDPR, PCI DSS, BSI KRITIS)
✅ Reputational damage (downtime, loss of customer trust, legal action)

Fact: 90% of all web apps contain at least one critical vulnerability (Source: OWASP Top 10, 2021)

Our Mission: Enterprise-Grade Web Security

We follow the OWASP Web Security Testing Guide (WSTG) and deliver:

✔ In-depth penetration testing (manual + automated)
✔ Full OWASP Top 10 coverage
✔ Audit-ready compliance evidence (GDPR, ISO 27001, PCI DSS)
✔ Gamified training using OWASP Juice Shop (CTF events & workshops)

All assessments are aligned with the OWASP WSTG — the global standard for web application security.

For Enterprises: Meet Compliance & Reduce Risk

The Challenges:

We need a pentest for GDPR / PCI DSS — with clear, actionable recommendations.”
“Our web apps are complex — how do we test all components (frontend, backend, APIs)?”
“Our developers need to take ownership of security — but how do we motivate them?

How We Help:

Regulatory-Compliant Penetration Tests

  • GDPR: Article 32 (Security of Processing)

  • PCI DSS: Requirements 6.1–6.6 (Secure Coding Practices)

  • BSI/KRITIS: For critical infrastructure operators

Tailored CTF Events

  • Team competitions using OWASP Juice Shop

  • Reward system: points, leaderboards, certificates

  • Long-term impact: security becomes part of team culture

Outcomes for Enterprises:

✅ Compliance documentation for audits (e.g., GDPR, ISO 27001)
✅ Risk reduction through proactive vulnerability mitigation
✅ Developers who are engaged and own security practices

For Developers: Integrate Security into the DevOps Process

The Challenges:

How do I catch security flaws in my code — before it goes live?”
“Our team needs hands-on security skills — dry trainings don’t work.”
“We want to embed security into CI/CD — but how?

How We Help:

Security Assessments for Developers

  • Code reviews (JavaScript, Python, Java, PHP...) based on OWASP ASVS

  • Automated scans (SAST/DAST) integrated into your pipeline (GitHub, GitLab, Azure DevOps)

Gamified Training with OWASP Juice Shop

  • 2–4 day workshops: hands-on hacking labs for your team

  • CTF events: competitive learning with reward systems (“Bug Bounty Light”)

Learning Outcomes:

  • Exploits: SQLi, XSS, CSRF, SSRF, IDOR

  • Secure API development (REST / GraphQL)

  • OWASP Top 10 in real-world practice

Developer-Friendly Reporting

  • Prioritized findings with fix examples and OWASP references

  • Seamless integration into Jira / ticketing systems

Outcomes for Dev Teams:

✅ Security embedded in your Definition of Done (DoD)
✅ Engaging learning through gamified challenges
✅ Certificates for participants (e.g., “OWASP Juice Shop Master”)

Frequently Asked Questions

For Developers:

Q: How long does a web app pentest take?
A: 1–3 weeks, depending on complexity (e.g., more time needed for multiple microservices and APIs)

Q: What does a pentest cost?
A: €5,000–€20,000 for standard apps (custom quotes for complex systems)

Q: Can you test Single-Page Applications (SPA)?
A: Yes! We test frameworks like React, Angular, Vue.js — and their backend APIs

Q: Do you offer training for our specific framework (e.g., Django, Spring Boot)?
A: Absolutely — our trainings are tailored to your tech stack

For Enterprises:

Q: Does the pentest meet GDPR requirements?
A: Yes. Our reports are aligned with GDPR Article 32 and BSI IT-Grundschutz

Q: How often should we conduct a pentest?
A: At least once per year — plus after major releases (e.g., new features)

Q: Can you test our vendor / third-party web apps too?
A: Yes. We provide comprehensive third-party risk assessments
