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

Hotelstars Union operates as a European organisation dedicated to harmonising hotel classification standards across 21 member countries. The website serves both hotel guests and hoteliers by providing a transparent and reliable rating system, digital classification tools, and comprehensive information about the classification criteria. The organisation positions itself as a trusted authority in the hospitality sector, promoting quality assurance and legal security of official hotel stars across Europe. Technically, the website is built on the TYPO3 CMS platform, enhanced with Bootstrap for responsive design, and integrates Google Maps API for hotel search functionality. The use of Weglot translation services indicates a focus on multilingual accessibility. Security-wise, the site enforces HTTPS and includes a cookie consent mechanism, though it lacks some advanced security headers and explicit privacy or security policies. The domain WHOIS data is privacy protected under EURid policies, which is typical for .eu domains and does not raise immediate concerns. Overall, the website demonstrates a mature digital presence with good content quality and security posture, though improvements in privacy transparency and security documentation are recommended.

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.

Priority findings

5 findings rated critical or high. Fix these first.

  1. 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"

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

  2. 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
    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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 Hotelstars Union holds a significant market position as a pan-European standardisation body for hotel classification, leveraging a network of 21 member countries. Its business model is non-profit and focused on providing harmonised classification criteria, digital tools for hotels, and information resources for guests. The organisation benefits from partnerships with national hotel associations and uses its website as a central portal for hotel search and classification services. The multilingual support and integration of digital classification tests indicate a strategic approach to accessibility and user engagement. The absence of direct contact emails or phone numbers on the main portal suggests a controlled communication channel, possibly directing users to member associations or dedicated contact pages. The organisation's growth is supported by its expanding membership and the increasing adoption of its classification scheme across Europe.

Security posture

The website exhibits a solid security foundation with enforced HTTPS and a cookie consent banner compliant with GDPR requirements. The absence of exposed sensitive data and use of secure form submission methods are positive indicators. However, the lack of comprehensive security headers such as Content-Security-Policy and absence of published security policies or incident response information represent areas for enhancement. No vulnerabilities or outdated libraries were detected in the provided content. The domain's privacy-protected WHOIS registration aligns with privacy best practices for EU entities. To strengthen security posture, the organisation should consider publishing explicit privacy and security policies, implementing additional HTTP security headers, and establishing a vulnerability disclosure program.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service accessible from the main navigation.
  2. Implement additional HTTP security headers including Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options.
  3. Establish and publish a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  4. Provide clear contact information for data protection officers or security incident response teams.
  5. Enhance transparency around data retention and user privacy practices to improve GDPR compliance.

Technical notes

Notes

The website is built on TYPO3 CMS, a robust and widely used content management system, combined with Bootstrap for responsive design and Select2 for enhanced form controls. Integration with Google Maps API enables interactive hotel search functionality. The use of Weglot translation service supports multilingual content delivery. The site demonstrates good mobile optimization and accessibility features such as skip links and ARIA labels. Performance appears moderate with multiple CSS and JS assets loaded, but no critical performance bottlenecks were identified. The technical stack is modern and well-maintained, though opportunities exist to optimize loading times and implement advanced security headers. Hosting provider details were not discernible from the content.
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.
