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

9 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

      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

    • 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 targets the energy and retail sectors, focusing on chimney and fireplace products. Its business model combines e-commerce sales with installation services, catering to residential and commercial customers in the Czech Republic. The website indicates a medium-sized enterprise with a consistent brand presence and trust signals such as a physical showroom and clear contact details. Marketing efforts include Google Ads and retargeting via Facebook and Google Analytics. The lack of WHOIS transparency is a concern but does not currently impact operational credibility. The company could benefit from publishing additional security and incident response information to enhance trust.

Security posture

The website demonstrates a mature security posture with HTTPS enforced, CSRF protection on forms, and cookie consent management. However, explicit security headers like Content-Security-Policy and X-Frame-Options are not evident, which could be improved to mitigate clickjacking and content injection risks. No vulnerabilities or exposed sensitive data were detected in the HTML content. The absence of a published security policy or incident response contact limits transparency. Overall, the security posture is good but could be enhanced with additional headers and formalized security disclosures.

Recommendations

  1. Implement and enforce security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  2. Publish a clear security policy and incident response contact information on the website.
  3. Verify and update WHOIS domain registration information to improve trust and transparency.
  4. Regularly update third-party libraries and scripts to mitigate potential vulnerabilities.
  5. Consider adding a security.txt file to facilitate vulnerability reporting and improve security culture.

Technical notes

Notes

The website is built on the Shoptet e-commerce platform, utilizing jQuery 1.11.3, Google Tag Manager, Google Analytics (GA4), Facebook SDK, and Tawk.to live chat. The site loads with moderate performance and is mobile optimized with good accessibility features. SEO is well addressed with proper meta tags and Open Graph data. The technical stack is modern but could benefit from updating jQuery to a more recent version to reduce security risks. Hosting provider details are not explicit. Overall, the technical infrastructure supports a professional e-commerce experience with room for modernization and enhanced security configurations.
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.
