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

Das Kartenhaus is a small German ticketing service operating since 2021, providing event ticket sales at 8 physical locations and online via affiliate partnerships with platforms like eventim.de. The website is built on WordPress using the Vantage theme and includes standard cookie consent mechanisms compliant with GDPR. The technical infrastructure is moderate in performance with good mobile optimization but lacks advanced security headers and DNSSEC. Security posture is adequate with HTTPS enforced but could be improved with additional security controls. No explicit incident response or security policies are published. Overall, the business appears legitimate and trustworthy with clear contact phone information and transparent affiliate disclosures.

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.

GDPR is indicative only, based on publicly visible signals: Articles 7, 12, 13 and 32 of Regulation (EU) 2016/679 and Article 5(3) of the ePrivacy Directive. Not a certification or legal assessment.

Priority findings

4 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. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality

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

The company targets event attendees and organizers in Germany, offering ticket sales and distribution services. Its business model includes physical sales points and online affiliate marketing. The market position is regional with partnerships to major ticket platforms. The website content is professional and consistent with the business focus. No social media presence or additional certifications were found. The company is relatively new but domain registration details align with the business claims.

Security posture

The website enforces HTTPS and uses cookie consent banners, indicating awareness of privacy compliance. However, the absence of DNSSEC and security headers like Content-Security-Policy or X-Frame-Options represents a security gap. No vulnerability disclosure or incident response contacts are published, which limits transparency. No exposed sensitive data or vulnerable libraries were detected in the HTML content. Overall security maturity is moderate but could be enhanced with standard best practices.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security.
  2. Implement security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Publish a security policy and incident response contact information to improve transparency.
  4. Regularly update WordPress core, themes, and plugins to mitigate vulnerabilities.
  5. Consider adding verified contact email addresses for customer and security communications.

Technical notes

Notes

The website runs on WordPress CMS with the Vantage theme and uses jQuery and other standard JavaScript libraries. Hosting is provided by Cronon GmbH in Germany. The site uses HTTPS with a valid certificate but lacks DNSSEC. Performance is moderate with good mobile responsiveness. SEO and accessibility features are basic but functional. The cookie consent mechanism is implemented via the DSGVO All-in-One plugin with tarteaucitron.js for GDPR compliance. No advanced analytics or tracking services were detected.
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.
