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

Plzeňský Prazdroj, a. s. operates a comprehensive website promoting brewery tours, experiential programs, events, space rental, weddings, restaurants, and an e-shop for souvenirs. The company holds a strong market position in the Czech hospitality sector, leveraging its historic and modern brewery facilities to attract tourists and beer enthusiasts. The website is professionally designed with excellent content quality and clear navigation, targeting mature audiences interested in beer culture and related experiences. Technically, the site uses modern frameworks such as Next.js and React, with integrations for analytics and cookie consent, ensuring a good digital maturity level. Security posture is solid with HTTPS, security headers, and no visible vulnerabilities, though the absence of dedicated security and incident response pages is noted. Overall, the site is trustworthy and well-maintained, but the lack of WHOIS data reduces domain trustworthiness slightly.

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

7 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 Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

  2. Security headers

    Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.

    • High

      Missing Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

  3. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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.

Add-on

Leaked records that mention prazdrojvisit.cz, from OffSeq Breach.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

The business model focuses on experiential tourism and hospitality services centered around the Plzeňský Prazdroj brewery brand. Revenue streams include ticket sales for tours and experiences, event space rental, catering for weddings, and merchandise sales via the e-shop. The company targets tourists, local visitors, and corporate clients. The website's partnership ecosystem includes related domains for e-commerce and responsible drinking campaigns. The brand benefits from awards and strong recognition in the beer tourism market. Growth indicators include a diverse offering of tours and events, and a well-integrated digital presence.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, comprehensive security headers, and cookie consent mechanisms. No exposed sensitive data or vulnerable libraries were detected. However, the absence of a public security policy, incident response information, and vulnerability disclosure channels indicates room for improvement in transparency and readiness. The site does not publish a security.txt file or dedicated contact for security incidents, which could enhance trust and incident handling capabilities. Overall, the security risk is low but could be further mitigated by adding these elements.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and compliance.
  2. Establish and publicize an incident response and vulnerability disclosure process.
  3. Implement a security.txt file to facilitate responsible vulnerability reporting.
  4. Enhance WHOIS data availability and accuracy to improve domain trustworthiness.
  5. Continue monitoring and updating third-party scripts and tracking tools for security.

Technical notes

Notes

The website is built on a modern React and Next.js stack, ensuring server-side rendering and good SEO performance. It uses Toastify for notifications and integrates Google Tag Manager and Cookiebot for analytics and privacy compliance. The site is mobile-optimized with responsive design and accessibility considerations. Performance is moderate, with multiple CSS and JS chunks loaded asynchronously. No CMS is explicitly detected, suggesting a custom or headless CMS solution. Hosting provider details are not evident from the data. The technical implementation supports a professional user experience but could benefit from performance optimizations and enhanced accessibility features.
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.
