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.

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

    • 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. 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"

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

STONE holds a strong market position as one of Europe's oldest importers and a key player in the international natural stone project market. Their business model combines manufacturing, supply, and international trading, targeting professional sectors such as architecture and construction. The company leverages partnerships and a broad product portfolio to maintain competitive advantages. Their digital presence supports multiple languages and showcases extensive project references, indicating a growth-oriented and internationally active business. The absence of detailed privacy policies and security disclosures suggests room for maturity in compliance and security transparency.

Security posture

The website demonstrates a solid security baseline with HTTPS and no exposed sensitive data. However, the lack of explicit security headers (e.g., CSP, HSTS) and absence of a vulnerability disclosure policy or security.txt file indicate opportunities for improvement. No incident response contacts or security policies are published, which could affect readiness and trust in case of security events. The use of Google Tag Manager introduces moderate user tracking, which is managed via cookie consent. Overall, the security posture is good but could be enhanced by adopting best practices and transparency measures.

Recommendations

  1. Implement and publish a comprehensive privacy policy and terms of service to improve compliance and user trust.
  2. Add security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options to strengthen site security.
  3. Publish a vulnerability disclosure policy or security.txt file to facilitate responsible reporting and incident response.
  4. Enhance transparency around data collection and retention policies to align with GDPR and privacy best practices.
  5. Regularly audit third-party scripts and tracking tools to minimize privacy risks and improve performance.

Technical notes

Notes

The website is built on Drupal 11, a modern and supported CMS, indicating good technical infrastructure. It uses Google Tag Manager for analytics and Google Fonts for typography, along with Slick Slider for interactive content. The site is mobile-optimized and accessible, with good SEO metadata and structured data (JSON-LD) for enhanced search engine understanding. Performance is moderate, likely due to rich media content and sliders. There is no indication of outdated or vulnerable libraries. Opportunities exist to optimize security headers and improve privacy disclosures. Overall, the technical implementation supports a professional and scalable web presence.
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.
