Risk levelMedium

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

Vinařství Sádek, affiliated with the Czech University of Life Sciences Prague, operates as a winery and hospitality provider located in the Moravian region of the Czech Republic. The business focuses on producing quality wines from local grape varieties and offers accommodation services near their vineyards, targeting wine enthusiasts and tourists. The website presents a professional image with clear navigation and relevant content, supporting their niche market position. Technically, the site is built on WordPress using Elementor and Yoast SEO, hosted on Websupport infrastructure, and includes modern tracking and consent management tools. Security posture is adequate with HTTPS and cookie consent implemented, but lacks published privacy policies and security headers. WHOIS data shows inconsistencies with a future domain creation date, which should be verified to ensure legitimacy. Overall, the site is mature and trustworthy for its business domain but would benefit from enhanced privacy and security documentation.

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

      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

  2. Security headers

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 leverages its university affiliation to establish credibility in the winemaking sector, focusing on quality and tradition. Its business model combines wine production with hospitality services, including accommodation at vineyard locations, appealing to tourists and wine lovers. The partnership with regional tourism platforms like kudyznudy.cz enhances its market reach. The website's content and structure support a small-sized enterprise with a clear regional focus. There is no evidence of large-scale commercial operations or subsidiaries. The business appears stable with a consistent brand presence and moderate digital marketing efforts via Google Analytics and Tag Manager.

Security posture

The website employs HTTPS ensuring encrypted communications and uses a cookie consent banner compliant with GDPR principles. However, it lacks explicit privacy policies, terms of service, and incident response contacts, which are critical for compliance and user trust. No advanced security headers were detected, and no vulnerability disclosures or security certifications are published. The use of third-party scripts like Google Analytics and CookieFirst introduces moderate tracking but no apparent vulnerabilities. The WHOIS inconsistency regarding domain registration date is a concern that may impact trustworthiness. Overall, the security posture is moderate but could be improved by formalizing policies and enhancing technical security controls.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service to improve legal compliance and user trust.
  2. Implement security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to harden the website against common attacks.
  3. Add an incident response or abuse contact email to facilitate security issue reporting.
  4. Verify and correct WHOIS domain registration data to align with business claims and improve legitimacy.
  5. Conduct regular security audits of third-party scripts and plugins to mitigate potential vulnerabilities.

Technical notes

Notes

The website is built on a modern WordPress CMS platform using Elementor for page building and Yoast SEO for search optimization. It integrates Google Tag Manager and Google Analytics for tracking and uses CookieFirst for cookie consent management. Hosting is provided by Websupport, inferred from nameservers. The site loads with moderate performance and is mobile optimized. Accessibility features are basic but present. The technical stack is current and well-supported, though some improvements in security headers and privacy documentation are recommended to reduce technical debt and enhance 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.
