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 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

    • 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

The company operates in the manufacturing and retail sectors of construction materials, targeting contractors, retailers, and end consumers. Its business model revolves around product manufacturing, sales, and value-added services such as mixing and technical support. The presence of multiple regional partner domains suggests a broad market reach in Central and Eastern Europe. The website content and structure indicate a focus on product education, customer support, and brand trust. The company leverages social media channels for marketing and customer engagement. No direct revenue or financial data is available, but the comprehensive product catalog and service offerings imply a stable market position.

Security posture

The website demonstrates a good security baseline with HTTPS and a consent management platform controlling tracking scripts and reCAPTCHA usage. No sensitive data leakage or vulnerable libraries were detected in the HTML content. However, the absence of explicit security policies, incident response information, and security.txt files indicates room for improvement in transparency and preparedness. Security headers like Content-Security-Policy and X-Frame-Options are not evident, which could enhance protection against common web attacks. Overall, the security posture is adequate for the business type but could be strengthened with additional best practices and documentation.

Recommendations

  1. Implement comprehensive security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance web security.
  2. Publish a dedicated security policy and incident response page to improve transparency and readiness.
  3. Add a vulnerability disclosure policy or security.txt file to facilitate responsible reporting of security issues.
  4. Enhance accessibility features to meet higher compliance standards and improve user experience for all visitors.
  5. Consider exposing verified company contact emails for security and support purposes while maintaining spam protection.

Technical notes

Notes

The website uses a modern tech stack including jQuery 3.7.1, Moment.js, Bootstrap framework, and Usercentrics for consent management. Google Tag Manager is employed for analytics and marketing tracking. The site appears to be built on Kentico Xperience CMS, inferred from URL patterns and structure. Performance is moderate with responsive design and mobile optimization. SEO practices are good with proper meta tags and structured navigation. Some technical debt may exist due to reliance on older libraries like jQuery, but overall the infrastructure supports a professional and functional user experience.
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.
