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

Plavírna is a hospitality business operating a historic renovated factory venue in Karlovy Vary, Czech Republic, specializing in weddings, events, and accommodation. The website presents a professional and visually appealing platform with clear navigation and comprehensive service descriptions. The technical infrastructure leverages modern JavaScript libraries, Google Tag Manager, Google Analytics, and Facebook Pixel for analytics and marketing. The site is hosted on a specialized platform (Previo) tailored for hospitality businesses. Security posture is generally good with HTTPS enforced and cookie consent implemented, but lacks visible security headers and published privacy or terms policies. The absence of WHOIS data limits domain trust transparency but is common for privacy-protected domains. Overall, the website is credible, safe, and well-positioned for its market niche.

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

  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 targets individuals and organizations seeking event venues and accommodation in the Karlovy Vary region. Its competitive advantage lies in the unique historic-industrial ambiance combined with modern amenities and a pet-friendly policy. Revenue streams include venue rental, accommodation bookings, and non-residential space leasing. The business maintains active social media channels to engage customers and uses marketing tools for targeted advertising. The website content and structure support a clear business model focused on hospitality and event services. Growth potential exists through enhanced digital presence and formalized privacy and security policies.

Security posture

The website demonstrates a moderate security maturity level with HTTPS and cookie consent mechanisms in place. However, it lacks published privacy policies, terms of service, and incident response contacts, which are important for compliance and user trust. No security headers were detected, which could improve protection against common web attacks. The use of third-party analytics and marketing scripts introduces moderate tracking but is managed with user consent. No vulnerabilities or exposed sensitive data were found in the content. The business should prioritize formalizing security policies and enhancing technical security controls to improve compliance and resilience.

Recommendations

  1. Publish a comprehensive privacy policy page detailing data collection and user rights.
  2. Add a terms of service page to clarify user agreements and liability.
  3. Implement security headers such as Content Security Policy, HSTS, and X-Frame-Options.
  4. Provide clear incident response and abuse contact information on the website.
  5. Regularly review and update third-party scripts to mitigate potential vulnerabilities.

Technical notes

Notes

The website uses a modern tech stack including jQuery, Leaflet.js for maps, and Google/Facebook analytics and marketing tools. It is built on the Previo CMS platform specialized for hospitality businesses. The site is hosted on staticsites.previo.cz, indicating a managed hosting environment. Performance is moderate with good mobile optimization and accessibility features. SEO is supported by proper meta tags and Open Graph data. The site uses asynchronous script loading to improve load times. Technical debt appears low, but the absence of security headers and formal privacy documentation indicates areas for modernization and compliance improvement.
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.
