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

2 findings rated critical or high. Fix these first.

  1. 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.

    • Critical

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

  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 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

STIB-MIVB holds a dominant position in Brussels' public transport sector, serving a large user base with extensive transit options. Their business model centers on providing transportation services funded by ticket sales and public funding. The website supports this by facilitating ticket purchases and providing travel information. The company maintains active engagement through social media and promotes related mobility services and partnerships, such as with Belgian national trains and local commercial ventures. The digital platform reflects a focus on user experience, accessibility, and compliance with privacy regulations, indicating strategic investment in customer satisfaction and regulatory adherence.

Security posture

The website demonstrates a good security baseline with HTTPS and cookie consent mechanisms. However, the absence of explicit security headers like Content-Security-Policy and X-Frame-Options suggests room for improvement. No vulnerabilities or exposed sensitive data were detected in the HTML content. The lack of a published security policy or incident response contact is a gap in transparency and readiness. GDPR compliance is evident through privacy policies and consent management. Overall, the security posture is solid but could be enhanced by adopting additional best practices and publishing security-related information.

Recommendations

  1. Implement and enforce security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to enhance protection against common web attacks.
  2. Publish a clear security policy and provide dedicated incident response contact information to improve transparency and trust.
  3. Consider creating and hosting a security.txt file or vulnerability disclosure program to encourage responsible reporting of security issues.
  4. Regularly audit third-party scripts and libraries to ensure no vulnerabilities are introduced via dependencies.
  5. Enhance WHOIS transparency if possible, or provide clear organizational information on the website to compensate for registry privacy.

Technical notes

Notes

The website is built on the Jahia CMS platform, utilizing Bootstrap 5 for responsive design and FontAwesome for icons. It integrates Mapbox for mapping services and Google Tag Manager for analytics. Cookiebot manages cookie consent, ensuring compliance with privacy regulations. The site is multilingual and optimized for accessibility, holding an AnySurfer accessibility certification. Performance is moderate with asynchronous loading of scripts and a clean HTML structure. There is no evidence of outdated or vulnerable libraries. The technical infrastructure supports a professional and user-friendly experience but could benefit from enhanced security headers and further performance tuning.
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.
