Security testing as part of quality assurance

Why security testing belongs in every test strategy

Security vulnerabilities are quality defects. An application that works but can be attacked does not meet its requirements. That is why we treat security testing not as a separate add-on but as an integral part of quality assurance.

Most vulnerabilities are not caused by exotic attacks but by known, avoidable mistakes: missing input validation, insecure authentication, overly broad access rights. Structured testing finds exactly these mistakes early – long before they become a risk in production. That is safer and cheaper than any fix after go-live.

What we test

  • Vulnerability analysis: systematic checks for known security flaws, based on the OWASP Top 10.
  • Input and validation tests: injection vulnerabilities, faulty input validation and insecure data processing.
  • Authentication and access control: login, session handling and authorisation concepts.
  • Security regression: so that closed vulnerabilities do not reopen with new releases.
  • CI/CD integration: automated security checks in your development pipeline.

Security and quality from a single source

When security testing and functional testing go hand in hand, we already know your application and where its critical points are. Instead of isolated audits, you get a complete picture of quality: functional, stable and secure.

We document all results transparently, prioritised by criticality and with concrete recommendations.

Frequently asked questions

What is security testing?

Security testing checks software specifically for vulnerabilities, for example in input handling, authentication and access rights. It is part of quality assurance and accompanies development instead of coming only at the end.

Is security testing the same as a penetration test?

No. Security testing within quality assurance checks continuously and systematically for known vulnerabilities. A penetration test simulates a targeted attack by specialised pentesters. The two complement each other – for a penetration test we recommend specialised providers.

What standards do your tests follow?

The OWASP Top 10, the most common security risks for web applications, and the principles of the ISTQB.

Services

More focus areas

Secure software must also be usable by everyone – and AI features bring their own risks. These two areas are often part of the picture.

  1. Accessibility testing

    WCAG 2.2, EN 301 549 and BITV 2.0. BFSG-compliant audits with an action plan and a template for your accessibility statement.

  2. AI & GenAI testing

    Testing AI systems for reliability and robustness – and using generative AI for more efficient testing.
