0–100, higher is better. How it is calculated

QuinBook, powered by WOIZZER AG, is a specialized SaaS platform offering comprehensive booking and management solutions tailored for the escape room industry. With over eight years of industry-specific expertise and two decades of IT experience, QuinBook positions itself as a leading solution for escape room operators worldwide. The platform provides features including escape game management, ticketing, staff coordination, and integrated payment processing, targeting small to medium-sized businesses primarily in Germany and internationally. The business model is subscription-based with flexible monthly billing and no long-term contracts, appealing to operators seeking scalable and professional management tools. Technically, the website employs a custom-built infrastructure leveraging established front-end libraries such as Bootstrap, FontAwesome, and jQuery, alongside modern UI components like Slider Revolution and hCaptcha for security. While the site is mobile-optimized and presents a professional user experience, some technical debt is evident with the use of an outdated jQuery version and lack of explicit security headers. Hosting is claimed to be German-based, supporting data sovereignty and compliance. From a security perspective, the site enforces HTTPS, uses encrypted communication, and integrates hCaptcha to mitigate spam on contact forms. Payment transactions are handled via external trusted providers, enhancing transactional security. However, the absence of explicit security headers and a cookie consent mechanism indicates areas for improvement in compliance and defense-in-depth. No incident response or vulnerability disclosure information is publicly available, which could be enhanced to build trust. Overall, QuinBook demonstrates a solid business and technical foundation with a high trustworthiness level. Strategic improvements in security headers, privacy compliance, and modernization of libraries would elevate its security posture and regulatory adherence, further strengthening its market position and customer confidence.

This scan rated NIS2 with an earlier keyword method that is no longer shown; rescan for the per-article view. Risk management, continuity, supply chain, training, MFA, management oversight (Art. 20) and incident reporting (Art. 23) need internal evidence, and Guard cannot tell whether NIS2 applies to this organisation.

Priority findings

7 findings rated critical or high. Fix these first.

  1. Security headers

    Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.

    • High

      Missing Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

Results by check

Each check with its score, findings and the evidence it collected.

How this score is calculated

The security score runs 0–100, higher is better. It is the plain average of the security checks that completed in this scan, each counted equally. A check that could not run is left out: it counts neither as a pass nor as a fail.

Not counted

  • NIS2 outside view: Re-weights evidence from the TLS, email, DNS, network and hygiene checks, so counting it would count that evidence twice. Shown on its own.
  • OffSeq Observations: An AI reading of the site, useful context but not reproducible evidence. Shown on its own.

Findings that cap the score at 49

Each of these is serious on its own, so while any is present the site cannot rate better than high risk, however good the other checks are.

  • The certificate is not trusted by browsers
  • The website is not served over HTTPS
  • A database, remote desktop, file-sharing or Telnet service is reachable from the internet
  • The page loads a script from a compromised source
  • The domain registration has expired
  • SPF authorises every server to send mail as the domain

Partial scans

When the site blocks Guard or most checks cannot run, the score covers only the checks that ran (usually DNS and email), is capped at 75 and is shown as partial, without a risk level.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

QuinBook operates in the niche market of escape room management software, leveraging deep industry knowledge to differentiate itself from generic booking systems. Its subscription SaaS model provides predictable revenue streams with flexibility for customers. The company maintains a strong partnership ecosystem with over 100 satisfied customers, including notable escape room operators across Europe and Australia. The platform's integration of affiliate programs and marketing tools like Google Analytics indicates a focus on growth and customer acquisition. The business targets small to medium-sized operators, emphasizing ease of use, comprehensive features, and localized support from its German base. The absence of long-term contracts and the provision of multiple language options (German and English) suggest a customer-centric approach aimed at international scalability.

Security posture

The website exhibits a moderate security maturity level with HTTPS enforced and encrypted communications. The use of hCaptcha on forms is a positive anti-spam measure. However, the lack of visible security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options reduces defense-in-depth. The outdated jQuery library version 1.11.2 presents a potential vulnerability vector. No public incident response or vulnerability disclosure policies are present, limiting transparency and preparedness. Payment processing is securely outsourced to external providers, mitigating direct PCI compliance burdens. GDPR compliance is partially addressed with a privacy policy but lacks cookie consent mechanisms. Overall, the security posture is adequate but would benefit from enhancements in headers, library updates, and formalized security policies.

Recommendations

  1. Implement comprehensive security headers including CSP, HSTS, X-Frame-Options, and X-Content-Type-Options to strengthen browser security.
  2. Upgrade all JavaScript libraries, especially jQuery, to supported and secure versions to mitigate known vulnerabilities.
  3. Introduce a cookie consent banner/mechanism to comply fully with GDPR and enhance user privacy transparency.
  4. Publish an incident response contact and vulnerability disclosure policy or security.txt file to improve transparency and trust.
  5. Conduct regular security audits and penetration testing to identify and remediate potential vulnerabilities proactively.

Technical notes

Notes

The website is built on a custom platform utilizing popular front-end frameworks and libraries such as Bootstrap, FontAwesome, and jQuery 1.11.2. It integrates advanced UI components like Slider Revolution and uses hCaptcha for form security. The site is mobile responsive and offers a good user experience with clear navigation and professional design. Hosting is claimed to be German-based, supporting data privacy compliance. However, the use of an outdated jQuery version and absence of security headers indicate technical debt and potential security risks. Performance is moderate with no explicit optimization indicators. SEO is basic with standard meta tags but no advanced structured data or Open Graph tags detected. Accessibility features are minimal but present. Overall, the technical implementation is solid but would benefit from modernization and enhanced security practices.
Standards and sources

Reference chips under each finding point to the standard, regulation or specification the finding relates to. They are taken from the official datasets below and mapped conservatively: a finding with no defensible link shows none. NIS2 and GDPR references mark where a finding is relevant evidence, not a compliance verdict. Implementing Regulation (EU) 2024/2690 binds digital infrastructure and digital service providers; for other entities it is the most detailed public reading of the Article 21 measures. WCAG, EN 301 549, European Accessibility Act and Web Accessibility Directive references name the requirement an automated accessibility rule relates to; they are not a conformance verdict.
