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

Galerie Koruna spol. s r. o. is a small Czech art gallery established in 2000, specializing in exhibitions and sales of Czech and international fine arts from the 20th and 21st centuries. The website presents a professional and consistent brand image with clear navigation and relevant content targeting art enthusiasts and collectors. The business model focuses on hosting exhibitions and selling artworks, supported by artist profiles and event updates. The company maintains a local market presence with a physical gallery in Hradec Králové, Czech Republic. Technically, the website uses modern web technologies including JavaScript, CSS, and integrates Google Analytics and Google Tag Manager for visitor tracking. The site is mobile optimized and SEO friendly, though accessibility features are basic. HTTPS is properly implemented ensuring secure communications. However, the absence of security headers and privacy/cookie policies indicates room for improvement in security and compliance. From a security perspective, the website shows a moderate security posture with no visible vulnerabilities or exposed sensitive data. The lack of WHOIS data reduces domain trustworthiness, but the website content and contact information appear legitimate. No WAF or blocking mechanisms were detected, and the site is fully accessible. Privacy compliance is weak due to missing policies and consent mechanisms. Overall, the website is a good representation of a small art gallery business with professional content and moderate technical maturity. Strategic improvements in privacy compliance, security headers, and WHOIS transparency would enhance trust and security posture, supporting long-term business credibility and regulatory adherence.

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

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

Galerie Koruna operates in the niche art gallery sector within the Czech Republic, targeting art collectors and enthusiasts interested in Czech and international fine arts. The company leverages exhibitions and artwork sales as primary revenue streams. The website supports business operations by showcasing current and past exhibitions, artist medallions, and available artworks for sale. The presence of social media integration (Facebook) aids in community engagement and marketing. The business model is traditional with a physical gallery complemented by digital presence. Growth indicators are limited but the company maintains a consistent brand and local market position. No evident partnerships or subsidiaries were identified beyond a website development company mention. The company could benefit from enhanced digital marketing and compliance strategies to strengthen competitive advantage.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enabled and no visible sensitive data leaks. However, the absence of security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options is a notable gap that could expose the site to common web attacks. No vulnerability disclosure or incident response information is provided, limiting transparency and readiness. Privacy and cookie policies are missing, indicating compliance gaps with GDPR and related regulations. The use of Google Analytics and Tag Manager introduces moderate user tracking without clear consent mechanisms. Overall, the security culture appears basic, suitable for a small business but requiring improvements to meet higher standards and regulatory requirements.

Recommendations

  1. Implement comprehensive privacy and cookie policies with explicit user consent mechanisms to ensure GDPR compliance.
  2. Add essential security headers (Content-Security-Policy, X-Frame-Options, X-Content-Type-Options) to enhance protection against common web vulnerabilities.
  3. Publish a security.txt file or vulnerability disclosure policy to improve transparency and incident response readiness.
  4. Enhance accessibility features to improve compliance and user experience for all visitors.
  5. Regularly audit and update third-party scripts and tracking tools to minimize security risks and improve privacy compliance.

Technical notes

Notes

The website is built using standard web technologies including HTML5, CSS, and JavaScript, with integration of Google Analytics and Google Tag Manager for analytics and tracking. The site is mobile responsive and SEO optimized with proper meta tags and structured data (JSON-LD BreadcrumbList). No CMS or hosting provider information was detected. Performance is moderate with optimized images and lazy loading scripts. However, the lack of security headers and privacy compliance features indicates technical debt in security and regulatory adherence. The site could benefit from modernization efforts including enhanced accessibility, security hardening, and privacy-focused technical implementations.
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.
