Risk levelMedium

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

Büchergilde Gutenberg is a well-established German book community and cooperative founded in 1924, offering curated book subscription boxes, an online bookshop, and literary events. The website reflects a professional and consistent brand presence targeting German-speaking book lovers and literature enthusiasts. Technically, the site uses modern frameworks such as Next.js and React, with good mobile optimization and SEO practices. Security posture is adequate with HTTPS enabled but lacks visible security headers and formal privacy or cookie policies. No incident response or vulnerability disclosure information is provided, which could be improved to enhance trust and compliance. Overall, the domain and website appear legitimate and consistent with the business history and sector.

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

5 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 Consent Banner found

      GDPR requires explicit consent for non-essential cookies

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

  3. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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 business operates in the retail sector focusing on books and literature, leveraging a subscription model and cooperative structure. It maintains partnerships with bookstores and has received industry recognition such as the Deutscher Verlagspreis 2025. The target audience is niche but loyal, consisting of readers interested in curated literary content. The website supports the business model with product showcases, subscription options, and community engagement. Growth potential lies in expanding digital presence and enhancing user engagement through events and exclusive content.

Security posture

The website employs HTTPS and modern web technologies, which is positive. However, the absence of security headers like CSP, HSTS, and X-Frame-Options reduces the security score. No security.txt or vulnerability disclosure policy is found, limiting transparency for security researchers. No contact emails or phone numbers related to security or incident response are visible. The site does not expose sensitive data or use vulnerable libraries based on the analysis. Overall, the security posture is moderate but could be strengthened by implementing best practices and clear policies.

Recommendations

  1. Publish comprehensive privacy and cookie policies with clear GDPR compliance statements.
  2. Implement and configure security headers such as Content Security Policy, HSTS, and X-Frame-Options.
  3. Add a security.txt file and provide clear contact channels for security incidents and vulnerability reporting.
  4. Enhance accessibility features to improve compliance and user experience for all users.
  5. Regularly audit third-party scripts and dependencies to ensure no vulnerabilities or privacy risks.

Technical notes

Notes

The website is built on Next.js and React, indicating a modern and scalable infrastructure. It uses Font Awesome for icons and Swiper.js for carousels. Hosting appears to be managed via your-server.de and related nameservers. Performance is moderate with deferred loading of scripts and responsive images. SEO is supported by proper meta tags and Open Graph data. Accessibility is basic but could be improved. No CMS is explicitly detected, suggesting a custom or headless CMS approach. Technical risks include missing security headers and lack of formal privacy and security disclosures.
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.
