0–100, higher is better. How it is calculated

The website sperkyakameny.cz operates as an e-commerce platform specializing in the sale of jewelry made from semi-precious stones, minerals, and pearls. It targets consumers interested in unique and quality jewelry pieces, offering a wide range of products categorized by stone types and jewelry styles. The site is well-structured and provides comprehensive product information, care instructions, and customer support channels, positioning itself as a niche retailer in the Czech market. Technically, the website utilizes a proprietary e-commerce platform (eshop-rychle.cz) and integrates modern analytics and marketing tools such as Google Tag Manager, Matomo, and Sklik retargeting. The site is served over HTTPS, ensuring encrypted communications, and is optimized for mobile devices with good navigation clarity. However, it lacks some security best practices such as security headers and a visible cookie consent mechanism. From a security perspective, the site demonstrates a moderate posture with HTTPS enabled and consent settings restricting analytics and ad storage by default. The absence of WHOIS data for the domain raises concerns about domain registration transparency and trustworthiness. No critical vulnerabilities or exposed sensitive data were detected in the provided content. Privacy policies and terms of service are present and appear comprehensive, supporting GDPR compliance. Overall, the website presents a professional and trustworthy front for its business, but the lack of domain registration data and some missing security headers suggest areas for improvement. Strategic recommendations include enhancing security headers, implementing a cookie consent banner, and verifying domain registration details to bolster trust and compliance.

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.

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

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

Sperkyakameny.cz occupies a specialized niche in the retail jewelry market, focusing on semi-precious stones and unique handcrafted pieces. Its business model is direct-to-consumer e-commerce, leveraging detailed product categorization and educational content to attract and retain customers. The site’s extensive product taxonomy indicates a broad inventory and expertise in mineralogy and jewelry craftsmanship. Revenue streams are primarily from online sales, supported by marketing via Google Ads and local Czech ad networks like Sklik. The presence of certifications and care instructions enhances customer confidence. The company appears small in size, targeting Czech consumers with potential for growth through expanded marketing and partnerships. The lack of visible parent or subsidiary companies suggests an independent operation. The platform’s integration with eshop-rychle.cz indicates reliance on a third-party e-commerce solution, which may influence operational scalability and technical flexibility.

Security posture

The security maturity of sperkyakameny.cz is moderate. The website enforces HTTPS, ensuring secure data transmission. It employs consent management to restrict analytics and advertising cookies by default, aligning with privacy best practices. However, the absence of key security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options reduces protection against common web attacks like clickjacking and MIME sniffing. No evidence of exposed sensitive data or vulnerable libraries was found in the HTML content. The lack of a visible cookie consent banner may be a compliance gap under GDPR. Incident response and security policy information are not publicly available, which could hinder rapid response to security events. The missing WHOIS data for the domain is a significant concern, as it impairs domain legitimacy verification and may indicate privacy protection or registration issues. Overall, the site should improve its security headers and transparency to enhance its security posture.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web vulnerabilities.
  2. Deploy a visible cookie consent banner to comply fully with GDPR and enhance user trust regarding data privacy.
  3. Verify and publish domain registration details to improve transparency and domain legitimacy trustworthiness.
  4. Regularly audit third-party scripts and analytics tools to ensure no vulnerabilities or privacy issues are introduced.
  5. Develop and publish a security policy and incident response plan accessible to users to demonstrate security commitment.

Technical notes

Notes

The website is built on the eshop-rychle.cz platform, a specialized e-commerce solution tailored for retail businesses. It uses modern web technologies including asynchronous JavaScript loading, CSS preloading, and integration with multiple analytics and advertising services. The site is mobile-optimized with responsive design elements and clear navigation menus. Performance is moderate, with some reliance on external static content delivery from golemos.com and third-party analytics domains. SEO is supported by proper meta tags and Open Graph data, enhancing social media sharing and search engine visibility. Accessibility features are basic but present. The technical stack is stable but could benefit from enhanced security configurations and performance optimizations such as security headers and cookie consent mechanisms. Hosting provider details are not explicitly identified from the content.
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.
