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: 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

  2. 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
    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

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

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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 reputable position in the German media sector, focusing on book publishing and sales. Its business model revolves around publishing, author promotion, and direct book sales, supported by events such as readings. The company leverages digital marketing and tracking tools to engage its audience. The presence of structured data and clear contact information enhances its credibility. However, the absence of explicit privacy and security policies may affect compliance perception. The company appears to operate independently without visible parent or subsidiary affiliations in the provided data.

Security posture

The website employs HTTPS and a cookie consent mechanism, reflecting basic GDPR compliance efforts. However, the lack of security headers such as Content Security Policy, HSTS, and X-Frame-Options reduces its defense-in-depth. No vulnerabilities or exposed sensitive data were detected in the HTML content. The use of third-party scripts introduces potential risk vectors that require ongoing monitoring. The absence of a published security policy or incident response contacts suggests limited transparency in security governance. Enhancing these areas would improve the overall security maturity and trustworthiness.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service to improve compliance and user trust.
  2. Implement standard security headers (CSP, HSTS, X-Frame-Options) to strengthen security posture.
  3. Establish and disclose a security policy and incident response contact information.
  4. Regularly audit and update third-party scripts to mitigate potential vulnerabilities.
  5. Enhance accessibility features and mobile optimization for better user experience.

Technical notes

Notes

The website is built using Next.js, a modern React framework, indicating a contemporary technical stack. It integrates cloud-based image hosting (Cloudinary) and marketing tools such as Facebook Pixel and Sendinblue for analytics and email marketing. The site appears moderately performant with good mobile optimization and SEO practices. However, no explicit hosting provider or CMS was identified. The absence of security headers and limited accessibility features highlight areas for technical improvement. Overall, the infrastructure supports a professional publishing platform but could benefit from enhanced security and compliance configurations.
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.
