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

    • High

      Third-party services without privacy policy

      Detected services: Facebook, LinkedIn, YouTube

      What to do: Document all third-party data sharing in your privacy policy

      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

The company holds a leadership position in the Czech industrial floor marking market, leveraging its long-standing experience and a dedicated quality team. Their business model focuses on B2B services, targeting industrial sectors requiring floor safety and maintenance solutions. The presence of localized domains in multiple countries indicates a regional expansion strategy. The company benefits from a strong brand presence supported by client testimonials and social media engagement. Revenue streams likely derive from service contracts for marking, cleaning, and floor reconstruction projects. The partnership ecosystem includes related localized domains and an online demand platform. Strategic observations suggest a stable medium-sized enterprise with growth potential through digital service offerings and regional market penetration.

Security posture

The website demonstrates a mature security posture with HTTPS enabled and CSRF protection implemented. However, the absence of key security headers such as Content-Security-Policy and X-Frame-Options represents an area for improvement. No vulnerabilities or exposed sensitive data were detected in the analysis. The lack of published security policies or incident response contacts limits transparency and preparedness perception. GDPR compliance is partially addressed through cookie consent and privacy policy, but no dedicated data protection officer or vulnerability disclosure information is available. Overall, the security maturity is good but could be enhanced by adopting additional best practices and transparency measures.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to enhance protection against common web attacks.
  2. Publish explicit security and incident response policies on the website to improve transparency and readiness.
  3. Regularly review and update third-party scripts and libraries to mitigate potential vulnerabilities.
  4. Enhance privacy compliance by providing clear data protection officer contact information and detailed GDPR compliance statements.
  5. Consider integrating automated security scanning and monitoring tools to proactively detect and address security issues.

Technical notes

Notes

The website is built on Joomla CMS with UIkit and jQuery libraries, reflecting a standard and maintainable technology stack. The use of modern JavaScript and CSS frameworks supports responsive design and good user experience across devices. Hosting is provided by Webglobe, s.r.o., a reputable Czech hosting provider. Performance is moderate with video content and multiple images, but no significant delays or errors were observed. Accessibility features are basic but present, including skip links and ARIA attributes. SEO optimization is basic with proper meta tags and structured navigation but could be improved with additional semantic markup and structured data. Overall, the technical infrastructure is solid with opportunities for modernization and enhanced performance optimization.
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.
