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

      Missing X-Frame-Options header

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

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

Estemia operates in the niche market of mineral and gemstone jewelry, targeting eco-conscious consumers and gift buyers. Their business model combines retail sales with social responsibility by supporting whale conservation. The company leverages partnerships with well-known environmental organizations to enhance brand trust and market appeal. The website content and navigation are well structured, supporting a positive user experience. The presence of custom jewelry options and a wide product range indicates a focus on personalized customer service. The company appears to be small in size with no public parent or subsidiary companies. Their marketing ecosystem includes multiple tracking and retargeting tools, indicating active digital marketing efforts.

Security posture

The website demonstrates a mature security posture with mandatory HTTPS and secure login forms. Cookie consent and privacy policies indicate GDPR awareness. However, the absence of security headers such as Content Security Policy, HSTS, and X-Frame-Options suggests room for improvement. No vulnerabilities or exposed sensitive data were detected in the HTML content. The lack of a published security policy or incident response contact reduces transparency in security management. The use of multiple third-party scripts requires ongoing vigilance to prevent supply chain risks. Overall, the site is secure for typical e-commerce operations but could enhance defenses and transparency.

Recommendations

  1. Implement comprehensive HTTP security headers including CSP, HSTS, X-Frame-Options, and X-XSS-Protection.
  2. Publish a clear security policy and incident response contact information on the website.
  3. Add a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Regularly audit and update third-party scripts and tracking tools to mitigate supply chain risks.
  5. Enhance accessibility features and conduct periodic security and privacy compliance reviews.

Technical notes

Notes

The website is built on the eshop-rychle.cz platform, using modern web technologies including Google Tag Manager, Google Analytics, Facebook Pixel, Matomo, and Smartsupp chat. The site loads CSS and JS resources asynchronously and uses Google Fonts for typography. Performance is moderate with good mobile optimization and SEO practices. The site uses a cookie consent modal with granular controls, indicating attention to privacy. No CMS vulnerabilities or outdated libraries were detected in the HTML. Hosting provider details are not explicitly available. The site could improve by adding security headers and enhancing accessibility compliance.
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.
