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

Tanlib operates as the public transportation network for the Niort Agglomeration in France, providing a free bus service across Niort and 45 surrounding communes. The website offers comprehensive information on routes, schedules, mobility services including bike rentals and carpooling, and real-time traffic alerts. The business is positioned as a key local transportation provider with partnerships including Niort Agglo and Transdev. Technically, the site is built on a PHP backend with modern JavaScript libraries and integrates third-party widgets such as Moovit for route planning and Matomo for privacy-conscious analytics. However, the lack of a valid SSL certificate and HTTPS implementation is a significant security shortfall. Privacy and cookie policies are well documented and include consent mechanisms, reflecting good GDPR compliance. Overall, the site is user-friendly, accessible, and professionally maintained but requires urgent improvements in security infrastructure.

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

8 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. 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

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

Tanlib's market position is that of a regional public transport provider offering free bus services, flexible transport options, and sustainable mobility solutions. Its competitive advantage lies in the free access model and integration with digital tools for route planning and mobility scoring. The target audience includes residents, commuters, students, and visitors within the Niort Agglomeration. Revenue streams are likely public funding and partnerships. The company maintains strategic partnerships with local government (Niort Agglo) and transport operators (Transdev). The website supports user engagement through personalized alerts and a newsletter. Growth indicators include recent service expansions and digital service enhancements.

Security posture

The website's security posture is currently weak due to the absence of HTTPS and a valid SSL certificate, exposing users to potential data interception risks. While some security best practices are observed, such as secure and HttpOnly cookies, the lack of HSTS, DNSSEC, DMARC, and other DNS security records increases exposure to DNS spoofing and email phishing risks. No explicit security or incident response policies are published, indicating limited transparency in security governance. The use of privacy-friendly analytics (Matomo) and cookie consent management is positive. Immediate remediation of SSL/TLS configuration and enhancement of security headers is recommended to improve trust and compliance.

Recommendations

  1. Acquire and deploy a valid SSL/TLS certificate to enable HTTPS across the entire site.
  2. Implement HTTP Strict Transport Security (HSTS) with includeSubDomains and preload directives.
  3. Configure DNSSEC, DMARC, and CAA DNS records to strengthen DNS and email security.
  4. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  5. Publish a clear security policy and incident response contact information to improve transparency.
  6. Regularly audit third-party scripts and libraries for vulnerabilities and update accordingly.
  7. Enhance session management with TLS session resumption and secure cookie attributes.

Notes

The website uses a custom PHP backend (version 8.2.28) served by nginx, with front-end technologies including jQuery, Flatpickr for date picking, Slim Select for enhanced select inputs, and integration of Moovit widgets for route planning. Analytics are handled by Matomo, a privacy-focused platform. The site is hosted on infrastructure managed by IPTWINS, as indicated by DNS and mail servers. Performance metrics are not provided but inferred as slow due to zero load time and resource count in the data. Accessibility features such as font size adjustment and audio reading are implemented, indicating good attention to inclusive design. SEO is supported by proper meta tags, Open Graph data, and structured JSON-LD organization data. The site lacks a known CMS, suggesting a custom development approach. Opportunities exist to improve performance and modernize security configurations.
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.
