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

Valtické Podzemí is a hospitality and wine tourism business based in the Czech Republic, specializing in historic wine cellar tours, wine tastings, and cultural events. The company operates a unique project connecting 13 historic wine cellars dating back to the 13th century, offering individual visits, group programs, and private events. The business holds a prestigious award, CHAMPION TOP VINAŘSKÝ CÍL ČR, underscoring its quality and reputation in the local market. The website is professionally designed, mobile-optimized, and rich in relevant content targeting wine enthusiasts, tourists, and corporate clients. Technically, the website is built on WordPress with modern JavaScript libraries such as Swiper.js and AOS for animations. It employs performance optimization tools like WP Rocket and SEO enhancements via Yoast SEO. The site uses Google Tag Manager and Microsoft Clarity for analytics and tracking, with a GDPR-compliant cookie consent mechanism in place. Social media integration and partner links further enhance its digital presence. From a security perspective, the site enforces HTTPS and implements cookie consent, but lacks explicit security policy and incident response information. No critical vulnerabilities or exposed sensitive data were detected. The absence of WHOIS data limits domain trust verification, but the presence of clear contact information and business details supports legitimacy. Overall, the site demonstrates a strong security posture with room for improvement in transparency and formal security documentation. Strategically, the business should focus on publishing a security policy, establishing incident response contacts, and enhancing domain registration transparency to improve trust. Continued monitoring of third-party scripts and regular security audits will help maintain a robust security posture. The website's excellent content quality and user experience position it well for growth in the wine tourism sector.

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

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

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

Business profile

Valtické Podzemí occupies a niche in the hospitality and wine tourism market, leveraging its historic wine cellars and cultural events to attract a mature audience interested in wine and regional heritage. Its business model combines direct consumer services such as individual visits and group programs with event hosting and archival wine storage. The company benefits from strategic partnerships with local wineries, tourism boards, and cultural organizations, enhancing its market reach and credibility. Revenue streams likely include ticket sales, event bookings, wine sales via an e-shop, and hospitality services. The website's integration with partner domains and social media channels indicates a well-developed ecosystem supporting customer engagement and marketing. Growth indicators include the launch of a 2025 event calendar and active social media presence. The business demonstrates competitive advantages through its award-winning status and unique historic offering, positioning it as a leader in regional wine tourism.

Security posture

The website exhibits a mature security posture with HTTPS enforced and cookie consent mechanisms aligned with GDPR requirements. The use of modern plugins and scripts appears secure, with no visible outdated or vulnerable libraries. However, the absence of a published security policy, incident response contacts, and vulnerability disclosure channels represents gaps in transparency and preparedness. No security.txt file or dedicated security framework references were found. The site could improve by explicitly publishing security policies, providing contact channels for security incidents, and implementing additional HTTP security headers. Overall, the risk of exploitation appears low, but formalizing security governance and incident response would enhance resilience and stakeholder trust.

Recommendations

  1. Publish a comprehensive security policy and incident response contact information on the website.
  2. Implement and document a vulnerability disclosure program, including a security.txt file.
  3. Enhance HTTP security headers such as X-Frame-Options and X-Content-Type-Options if not already present.
  4. Regularly audit and update third-party scripts and plugins to mitigate vulnerabilities.
  5. Increase domain registration transparency by ensuring WHOIS data is complete and publicly accessible.

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.
