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

Transports publics lausannois (TL) operates as the primary public transportation provider in the Lausanne region of Switzerland, offering bus, metro (m1, m2), and train (LEB) services. The website serves residents and visitors by providing schedules, ticketing options, real-time traffic updates, and customer support. The company maintains a strong market position as a key regional mobility provider with a comprehensive digital presence including social media and news portals. Technically, the website is built on WordPress 6.6.1 with modern JavaScript libraries such as Alpine.js and jQuery. It integrates multiple analytics and marketing tools including Google Tag Manager, Facebook Pixel, and TikTok Pixel. The site is mobile-optimized, accessible, and SEO-friendly, reflecting a mature digital infrastructure. From a security perspective, the site enforces HTTPS and avoids exposing sensitive data. However, some security headers are not explicitly detected, and there is no published security policy or incident response contact. Privacy compliance is partially addressed with a privacy policy and terms of service, but lacks a clear cookie consent mechanism. Overall, the website is professional, trustworthy, and well-aligned with the business's public transportation mission. Strategic improvements in security headers, privacy consent, and incident response transparency would enhance the security posture and regulatory compliance.

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. 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';…

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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 Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • 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: Google Analytics, Facebook, Twitter, LinkedIn, YouTube

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

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

TL holds a dominant position in the Lausanne public transport market, leveraging a broad service portfolio including buses, metro lines, and regional trains. Their business model focuses on providing mobility solutions with ticket sales and subscriptions as revenue streams. The company targets local residents, commuters, and visitors, supported by a strong digital ecosystem including dedicated portals for ticketing, customer accounts, and news. Partnerships with related domains such as leb.ch and their own online shop indicate a well-integrated service offering. The presence of career and assistance services suggests organizational growth and customer-centric operations.

Security posture

The website demonstrates a good baseline security posture with enforced HTTPS and no visible exposure of credentials or vulnerable libraries. The use of secure cookies and modern JavaScript frameworks supports security best practices. However, the absence of explicit security headers like Content-Security-Policy and lack of published security or incident response policies represent gaps. The extensive use of third-party tracking pixels increases the attack surface and privacy risks. No vulnerabilities or malware indicators were detected in the content. Enhancing header policies and publishing security documentation would improve maturity.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web attacks.
  2. Deploy a clear cookie consent banner/mechanism to comply fully with GDPR and other privacy regulations.
  3. Publish a dedicated security policy and incident response contact information to improve transparency and readiness.
  4. Regularly audit and update third-party scripts and tracking pixels to minimize vulnerabilities and privacy risks.
  5. Consider adding a security.txt file to facilitate responsible vulnerability disclosure and improve trust.

Technical notes

Notes

The website is built on a modern WordPress CMS with up-to-date core and plugins, including Yoast SEO for optimization. It uses jQuery and Alpine.js for frontend interactivity and integrates Google Tag Manager for analytics and marketing. The site loads multiple external scripts asynchronously to optimize performance. Mobile responsiveness and accessibility are well addressed. However, some security headers are missing, and no explicit hosting provider information was found. Performance is moderate, likely due to multiple external dependencies. Overall, the technical implementation is solid with room for security hardening.
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.
