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

Mattoni 1873 a.s. is a well-established Czech beverage company specializing in premium natural mineral waters and a broad portfolio of internationally recognized beverage brands. Founded in 1873, the company has grown into a market leader in Central Europe with operations spanning eight countries and a diverse brand portfolio. The website reflects a mature digital presence with good content quality, clear navigation, and a focus on sustainability and corporate responsibility. Technically, the site employs modern web technologies including Google Analytics, Google Tag Manager, and responsive design elements, though some security headers are missing. The security posture is strong with HTTPS enforced and cookie consent mechanisms in place, but could be improved by adding explicit security policies and vulnerability disclosure information. WHOIS data is unavailable, which slightly impacts trust but is mitigated by the company's visible branding and social media presence. Overall, the site is professional, user-friendly, and compliant with GDPR requirements.

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

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

Mattoni 1873 holds a dominant position in the Central European beverage market, leveraging a long heritage and a wide brand portfolio to serve consumers and Horeka partners. The business model focuses on manufacturing and distributing mineral waters, juices, and snacks with a strong emphasis on sustainability and quality. The company targets a broad consumer base across multiple countries, supported by a large workforce and multiple production facilities. Partnerships with e-commerce and whistleblowing service providers indicate a mature operational ecosystem. The website content and structure support brand trust and customer engagement, with clear media contacts and career opportunities. The absence of WHOIS data suggests privacy protection or registry issues but does not detract significantly from the company's market credibility.

Security posture

The website demonstrates a solid security foundation with HTTPS enabled and a comprehensive cookie consent mechanism aligned with GDPR. However, the absence of visible security headers such as Content Security Policy, HSTS, and X-Frame-Options represents an area for improvement. No exposed sensitive data or vulnerable libraries were detected in the HTML content. The lack of a published security policy or incident response contact limits transparency in security governance. The site does not provide a security.txt file or vulnerability disclosure program, which could enhance trust and facilitate responsible reporting of security issues. Overall, the security posture is good but could benefit from enhanced header configurations and formalized security communications.

Recommendations

  1. Implement standard security headers including Content Security Policy, HSTS, and X-Frame-Options to strengthen defense-in-depth.
  2. Publish a dedicated security policy page and incident response contact information to improve transparency and trust.
  3. Establish and publicize a vulnerability disclosure program, including a security.txt file, to encourage responsible reporting.
  4. Enhance accessibility features to improve compliance and user experience for all visitors.
  5. Regularly audit third-party scripts and tracking tools to ensure they do not introduce vulnerabilities or privacy risks.

Technical notes

Notes

The website uses a modern technology stack with asynchronous loading of Google Analytics and Tag Manager scripts, Typekit fonts for typography, and Owl Carousel for interactive content display. The site is mobile responsive with good navigation clarity and SEO optimization through proper meta tags. Performance is moderate, with lazy loading implemented for images to improve load times. No CMS is explicitly detected, suggesting a custom or proprietary platform. Hosting provider details are not discernible from the content. The site includes cookie consent and GDPR compliance mechanisms implemented via JavaScript modals and banners. Technical debt appears low, but the absence of security headers and explicit CMS identification suggests opportunities for modernization and enhanced security hardening.
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.
