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

7 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

  2. 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';…

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

Delius Klasing Verlag GmbH operates this niche media platform focusing on mountain biking, serving a specialized audience in Germany. The company leverages digital subscriptions and e-commerce to diversify revenue streams. The website's integration with Shopify and use of advanced frontend frameworks indicate a strategic investment in digital transformation. Social media channels are actively linked, enhancing brand reach. The absence of explicit privacy and cookie policies suggests a potential compliance gap. The market position is strong within the cycling media sector, with clear branding and consistent content quality.

Security posture

The website employs HTTPS and modern web technologies, which is positive for secure communications and performance. However, the lack of visible security headers such as Content-Security-Policy and X-Frame-Options reduces defense-in-depth. No incident response or vulnerability disclosure information is published, limiting transparency. No contact emails or phone numbers for security or general inquiries were found in the HTML snapshot, which may hinder user trust and support. The site uses third-party scripts including Marker.io and Stroer ads, which should be regularly audited for security risks. Overall, the security posture is moderate but can be enhanced by implementing recommended headers and policies.

Recommendations

  1. Publish a comprehensive privacy policy and cookie policy with clear GDPR compliance statements.
  2. Implement security headers like Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Add visible contact information including emails and phone numbers for general and security inquiries.
  4. Establish and publish an incident response and vulnerability disclosure policy.
  5. Regularly review and audit third-party scripts and advertising networks for security and privacy compliance.

Technical notes

Notes

The website uses a modern React and Next.js frontend framework with server-side rendering capabilities, enhancing SEO and performance. Shopify is used as the e-commerce backend, indicating a hybrid platform approach. The site is mobile-optimized with responsive design and includes progressive web app features. Performance is moderate, with multiple deferred scripts and preloaded CSS. Accessibility features appear adequate but could be further improved with ARIA roles and landmarks. SEO is supported by structured data (JSON-LD) and Open Graph tags. Technical debt is low, but the absence of security headers and explicit privacy mechanisms are notable gaps.
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.
