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

8 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

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 positions itself as a niche retailer in the Czech Republic with an international reach through its English website. Its competitive advantage lies in specialized services such as authenticity assessments and expert consultations, which add value beyond simple retail. The business model is primarily e-commerce retail, targeting collectors and investors in numismatics and related antiques. Revenue streams likely come from sales of collectibles and related services. The presence of expert services and certification mediation suggests a focus on quality and trustworthiness. The company maintains a clear brand identity and consistent messaging, which supports customer confidence. There is no evidence of partnerships or subsidiaries from the provided data. Growth indicators are not explicitly available, but the use of modern e-commerce technology and multilingual support indicates digital maturity.

Security posture

The website demonstrates a good security posture with HTTPS enabled and no exposed sensitive data in the HTML content. However, the absence of security headers such as Content-Security-Policy and X-Frame-Options represents an area for improvement. No incident response or security policy information is published, which could be a gap in transparency and readiness. The site uses secure forms with validation, but lacks cookie consent banners, which may affect GDPR compliance. No known vulnerabilities or malware indicators were detected. Overall, the security maturity is moderate to good, suitable for a small retail business but with room for enhancement in privacy and security transparency.

Recommendations

  1. Implement a cookie consent banner to comply with GDPR and enhance user privacy transparency.
  2. Add essential security headers like Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to improve protection against common web attacks.
  3. Publish a clear security policy and incident response contact information to build trust and readiness.
  4. Consider making WHOIS registrant information more transparent if business legitimacy verification is a priority.
  5. Regularly audit third-party scripts and tracking tools to ensure no vulnerabilities or privacy issues arise.

Technical notes

Notes

The website is built on the Prestashop e-commerce platform, utilizing jQuery and Google Tag Manager for analytics and marketing. It uses Cloudfront CDN for content delivery and Google Fonts for typography. The site is mobile optimized with responsive design and uses modern CSS and JavaScript libraries. Performance is moderate, with potential improvements in loading speed by optimizing images and scripts. Accessibility is basic but could be enhanced with ARIA roles and better keyboard navigation support. SEO is supported by proper meta tags, Open Graph tags, and structured data in JSON-LD format, improving search engine visibility. No major technical debt or outdated technologies were detected.
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.
