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

6 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

The company holds a strong market position as a specialist publisher with a long history and a focused business model centered on niche sports and automotive content. Revenue streams likely include book and magazine sales, event organization, and media sales partnerships. The presence of a dedicated online shop and webreader platform indicates digital sales channels. Partnerships with media sales and corporate publishing firms, as well as a career portal, suggest a well-integrated ecosystem. The target customers are enthusiasts and professionals in watersports, cycling, and automotive sectors. The company benefits from consistent branding and a professional online presence, supporting growth and customer engagement.

Security posture

The website employs HTTPS with a valid SSL configuration, ensuring secure data transmission. It uses a consent management platform to comply with GDPR cookie regulations, indicating good privacy practices. However, explicit security headers such as Content Security Policy (CSP), HSTS, or X-Frame-Options are not visible in the HTML content, which could be improved. No security policy or incident response contact information is published, which is a gap in transparency. No vulnerabilities or exposed sensitive data were detected. The security posture is good but could be enhanced by adding security headers and a formal security policy.

Recommendations

  1. Implement and verify HTTP security headers including CSP, HSTS, and X-Frame-Options to enhance protection against common web attacks.
  2. Publish a clear security policy and incident response contact information to improve transparency and trust.
  3. Add a security.txt file to facilitate vulnerability disclosure and improve security communication.
  4. Regularly audit third-party scripts and libraries to ensure no vulnerabilities are introduced.
  5. Enhance accessibility features to improve compliance and user experience for all users.

Technical notes

Notes

The website is built using modern web technologies such as React and Next.js, indicating a contemporary and scalable infrastructure. It leverages Contentful as a CMS and Cloudinary for image hosting, supporting efficient content management and delivery. The site includes a consent management platform for GDPR compliance and integrates third-party tools like Marker.io for bug reporting. Performance is moderate with good mobile optimization and SEO practices. There is no explicit hosting provider identified from the HTML content. The technical implementation is solid with room for improvement in security headers and accessibility compliance.
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.
