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

The website www.beer-coasters.eu is a niche hobbyist platform dedicated to the collection, exchange, and information sharing of beer coasters (beer mats) worldwide. Operated by Vladimir Gerlich since 2003, it serves a community of collectors with a focus on detailed images, brewery information, and exchange opportunities. The site is modest in scale, targeting enthusiasts and collectors primarily in the Czech Republic and internationally. Technically, the site uses classic web technologies such as jQuery and Floatbox, with integrations for Google Analytics and Tag Manager for visitor tracking. The infrastructure appears stable but basic, with moderate performance and limited mobile optimization. Security posture is adequate with HTTPS enabled but lacks advanced security headers and formal privacy or cookie policies, indicating room for improvement in compliance and user data protection. No WHOIS registrant data is available due to EURid privacy protections, but the domain age and content consistency support legitimacy. Overall, the site is functional and trustworthy for its niche audience but would benefit from enhanced security and privacy practices.

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.

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 · found on this site
  • 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 business operates as a small-scale, personal hobbyist website with a community focus on beer coaster collecting. Its market position is niche, serving collectors interested in beer memorabilia. The business model is informational and community-driven, with no evident commercial transactions or e-commerce. Revenue streams are likely minimal or non-existent, possibly supported by advertising via Toplist and tracking services. The target customers are hobbyists and collectors worldwide, with a particular emphasis on Czech and European beer coasters. The site maintains partnerships with related collector sites and hobbyist communities. Growth indicators are limited but steady, with regular updates on new coasters and active community engagement through guestbook and contact options. Strategic observations suggest potential for expansion by improving privacy compliance and enhancing mobile user experience.

Security posture

The website demonstrates a basic security maturity level with HTTPS enabled, protecting data in transit. However, it lacks critical security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options, which could mitigate common web attacks. No exposed sensitive data or vulnerable libraries were detected in the HTML content. The absence of privacy and cookie policies indicates compliance gaps with GDPR and related regulations. Incident response readiness is not evident, with no dedicated security contact or security.txt file. The use of third-party analytics and tracking scripts introduces moderate user tracking but without clear user consent mechanisms. Overall, the security posture is functional but requires enhancements to meet modern standards and regulatory requirements.

Recommendations

  1. Implement and publish a comprehensive privacy policy and cookie consent mechanism to improve GDPR compliance.
  2. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web vulnerabilities.
  3. Introduce a security.txt file and provide clear incident response contact information to improve transparency and readiness.
  4. Enhance mobile responsiveness and accessibility to improve user experience across devices.
  5. Review and minimize third-party tracking scripts or provide clear user opt-in options to align with privacy best practices.

Technical notes

Notes

The website uses a traditional web technology stack centered around jQuery and Floatbox for UI interactions and image galleries. It integrates Google Analytics and Tag Manager for visitor tracking and CompeteXL for additional analytics. The site is served over HTTPS, indicating basic encryption. Performance is moderate with some preloading of CSS and asynchronous loading of scripts. The HTML structure is valid and includes meta tags for SEO and Open Graph for social sharing. However, the site lacks modern frameworks or CMS platforms, which may limit scalability and ease of maintenance. Mobile optimization is basic, and accessibility features are minimal. There is an opportunity to modernize the tech stack, improve performance, and enhance compliance with web standards and security best practices.
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.
