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

Tadao operates as a regional public transportation network serving the Artois and Gohelle sectors in France, providing bus schedules, route planning, traffic updates, and on-demand transport services. The website reflects a medium-sized organization with a clear focus on user accessibility and service information, supported by a parent company, Transdev, a known global transport operator. The digital infrastructure is modern, leveraging JavaScript frameworks, cookie consent management, and analytics tools, with a CMS platform (ActiPAGE) generating the site content. Security posture is strong with HTTPS enforced and cookie consent mechanisms in place, though some security best practices like explicit security headers and incident response information could be improved. Privacy compliance is well addressed with accessible privacy and cookie policies in French, aligned with GDPR requirements. Overall, the site is professional, trustworthy, and well-positioned in its market niche.

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

6 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

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

    • High

      Third-party services without privacy policy

      Detected services: Facebook, Twitter, LinkedIn, YouTube

      What to do: Document all third-party data sharing in your privacy policy

  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

The company benefits from its association with Transdev and Artois Mobilités, enhancing its market credibility. Its business model centers on public transport services with additional revenue streams from e-commerce (ticketing and merchandise). The target audience includes local residents and commuters, with a loyalty program (O'Club) to enhance customer retention. The website's content and navigation are designed to facilitate easy access to schedules, routes, and customer support, indicating a customer-centric approach. Partnerships with regional mobility authorities and a strong social media presence support brand visibility and engagement.

Security posture

The website demonstrates a mature security posture with HTTPS and cookie consent management. No critical vulnerabilities or exposed sensitive data were detected. However, the absence of a published security policy, incident response contacts, and vulnerability disclosure mechanisms suggests room for improvement in transparency and readiness. The use of third-party analytics and callback services is managed with user consent, aligning with privacy regulations. Enhancing security headers and publishing security-related documentation would strengthen the overall security culture and compliance.

Recommendations

  1. Publish a dedicated security policy and incident response page to improve transparency and user trust.
  2. Implement and publicize a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  3. Enhance website security by adding HTTP security headers such as Content-Security-Policy and X-Content-Type-Options.
  4. Improve accessibility compliance to meet higher standards and broaden user inclusivity.
  5. Maintain and regularly audit third-party scripts and analytics tools to ensure ongoing privacy compliance.

Technical notes

Notes

The website is built using a modern JavaScript stack with jQuery and Bootstrap-like CSS classes, supported by ActiPAGE CMS. It integrates third-party services for cookie consent (tarteaucitron.io), analytics (ActiSTAT), and callback functionality (Freezcall). Performance is moderate with good mobile optimization and SEO practices. Accessibility is basic but could be improved. The site uses HTTPS exclusively, ensuring encrypted communication. No outdated or vulnerable libraries were detected in the provided HTML content. The technical infrastructure supports a professional and user-friendly experience but could benefit from enhanced security headers and accessibility improvements.
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.
