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

DuMont Buchverlag GmbH & Co. KG is a German book publishing company with a well-established market presence in the media sector. The website serves as a digital storefront and informational portal showcasing their book catalog, authors, and events. The target audience primarily consists of German-speaking book readers and literary enthusiasts. The business model focuses on publishing and selling books, promoting authors, and organizing literary events. The company maintains a consistent brand image and provides clear contact information, enhancing trust and credibility. Technically, the website is built using modern web technologies including Next.js (React framework), Cloudinary for image hosting, and integrates marketing and tracking tools such as Facebook Pixel and Sendinblue. The site is mobile-optimized with good SEO practices and basic accessibility features. Performance is moderate, with room for improvement in accessibility and security headers. From a security perspective, the website enforces HTTPS and implements a cookie consent mechanism aligned with GDPR requirements. However, it lacks explicit privacy policy and terms of service pages in the analyzed content, as well as a security policy or incident response contact. No critical vulnerabilities or exposed sensitive data were detected. The WHOIS data confirms the legitimacy of the domain with consistent registrant information matching the business location and sector. Overall, the website demonstrates a solid digital presence with good business credibility and technical implementation. Strategic improvements in security policies, privacy disclosures, and accessibility would enhance compliance and user trust. The risk profile is low, with no indications of malicious activity or content safety concerns.

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. GDPR outside view

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

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

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

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326

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

DuMont Buchverlag holds a strong position in the German publishing market, focusing on literary works including novels, non-fiction, and bestsellers. Their business model revolves around traditional publishing complemented by digital marketing and event promotion. The company targets readers in Germany, Austria, and Switzerland, leveraging a multi-channel approach including online sales and author events. The presence of structured data and marketing integrations indicates a mature digital marketing strategy. No parent or subsidiary companies were identified in the provided data. The company’s reputation is supported by clear contact details and consistent branding, positioning it as a trusted publisher in the media industry.

Security posture

The website exhibits a moderate security posture with HTTPS enforced and cookie consent implemented, reflecting awareness of GDPR compliance. However, the absence of security headers such as Content-Security-Policy and lack of a published security policy or incident response contacts represent gaps in security maturity. No vulnerabilities or exposed sensitive data were found in the HTML content. The use of third-party marketing and tracking scripts is standard but should be monitored for privacy compliance. The WHOIS data supports domain legitimacy, reducing risk of phishing or spoofing. Overall, the security posture is adequate for the business type but could be improved by adopting additional security best practices and transparency measures.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service pages accessible from the website footer.
  2. Implement and configure security headers including Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options.
  3. Create and publish a security policy and incident response contact information to improve transparency and readiness.
  4. Add a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  5. Enhance website accessibility to meet recognized standards and improve user experience for all visitors.

Technical notes

Notes

The website is built on a modern React-based framework (Next.js) with server-side rendering capabilities, enhancing SEO and performance. Images are served via Cloudinary, optimizing delivery. Marketing and analytics integrations include Facebook Pixel, Sendinblue, and Adobe DTM, indicating a sophisticated marketing stack. The site is mobile responsive and well-structured with semantic HTML and JSON-LD structured data for SEO. However, no explicit CMS was detected, suggesting a custom or headless CMS solution. Performance is moderate with potential for optimization in loading speed and accessibility compliance. Security headers are missing, representing a technical risk that should be addressed. Overall, the technical infrastructure supports the business needs but has room for security and accessibility improvements.
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.
