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

9 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

    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';…

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 cluster operates as an essential entity within the transportation and manufacturing sectors, focusing on aviation. It leverages partnerships and certifications such as TCI Network membership to bolster credibility. The business model revolves around cluster facilitation, project management, and promotional activities to support member companies. The website content and structure reflect a medium-sized organization with a regional focus and growing international outreach. The absence of direct contact emails or phone numbers on the homepage suggests controlled communication channels, likely centralized via contact forms. The presence of multiple language versions indicates an intent to engage broader European and international audiences.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforced and no visible sensitive data exposure. However, the lack of advanced security headers (e.g., CSP, X-Frame-Options) and absence of a security policy or incident response contacts indicate room for improvement. No vulnerability disclosures or security.txt files were found, which could hinder responsible vulnerability reporting. The use of third-party scripts and analytics is standard but should be monitored for privacy compliance. Overall, the security posture is adequate for the business type but would benefit from enhanced policies and technical controls.

Recommendations

  1. Implement comprehensive security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web attacks.
  2. Publish a security policy and incident response contact information to improve transparency and readiness.
  3. Add a security.txt file to facilitate responsible vulnerability disclosure.
  4. Enhance accessibility features to improve compliance and user experience for all visitors.
  5. Regularly review third-party scripts and tracking tools to ensure ongoing privacy compliance and minimize user tracking.

Technical notes

Notes

The website uses a modern technology stack including Bootstrap 5 and jQuery 3.6, ensuring responsive design and interactive features. Google Analytics and Tag Manager are integrated for traffic analysis, alongside MailerLite for marketing automation. The site loads external resources asynchronously to optimize performance, though hosting details are not explicitly available. SEO is supported by appropriate meta tags and Open Graph data. The site is mobile optimized with good navigation clarity. Technical debt appears low, but opportunities exist to improve security headers and accessibility compliance to reduce risks and enhance user experience.
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.
