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 Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

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 operates in the manufacturing sector, focusing on industrial floor services including safety marking, cleaning, and repairs. Their business model targets industrial and commercial clients requiring specialized floor services. The presence of multiple regional partner domains indicates a broad geographic reach within Central Europe. The company leverages digital marketing tools and maintains active social media profiles to support brand presence. Testimonials and references enhance credibility. The business appears stable with a medium size and a clear market leadership position in their niche. No certifications were found on the site, suggesting potential for further trust-building through formal certifications.

Security posture

The website enforces HTTPS and uses CSRF tokens, indicating attention to basic web security. Cookie consent is implemented with granular user controls, supporting GDPR compliance. However, no explicit security policy or incident response contacts are published, which could be a gap for security transparency. No vulnerable libraries or exposed sensitive data were detected in the HTML content. The absence of security headers like Content-Security-Policy or X-Frame-Options is a minor concern. Overall, the security posture is good but could be enhanced with additional policies and headers.

Recommendations

  1. Add a dedicated security policy page detailing security practices and incident response procedures.
  2. Implement and configure HTTP security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Publish contact information for security incidents (e.g., security@ or abuse@ email addresses).
  4. Regularly audit third-party scripts and update Joomla and dependencies to mitigate vulnerabilities.
  5. Consider obtaining and displaying relevant industry certifications to enhance trust.

Technical notes

Notes

The website uses Joomla CMS with jQuery and UIkit framework, providing a modern and responsive design. Google Tag Manager and Google Analytics are integrated for marketing and analytics. The site loads a video background and uses lazy loading for images, indicating moderate performance optimization. Accessibility features are basic but present, such as skip links and ARIA roles. SEO is supported by meta tags and structured JSON-LD data. Hosting provider details are not explicit, but the domain uses stable name servers. The site is mobile-optimized and has a clear navigation structure. Technical debt appears low, but security header implementation and performance monitoring could be improved.
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.
