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

ARTE is a well-established European cultural public broadcaster offering a wide range of documentaries, films, series, and concerts through its streaming platform arte.tv. The website targets a general audience interested in cultural and educational content, positioning itself as a trusted source for high-quality media. Technically, the site leverages modern web technologies including React and Next.js, ensuring fast performance, mobile optimization, and good accessibility. Security-wise, the site enforces HTTPS, implements security headers, and blocks outdated browsers, reflecting a mature security posture. However, the absence of public WHOIS data suggests privacy protection, which is justified for this type of entity.

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

3 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 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

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

ARTE operates in the media sector as a public broadcaster with a focus on European cultural content. Its business model revolves around providing free, ad-free streaming services funded by public means. The platform's strong market position is supported by its extensive content library and multi-language support. The company maintains a professional digital presence with official apps and social media channels, indicating a mature digital strategy. Partnerships and external domains relate mainly to content delivery and analytics, with no suspicious affiliations detected. The lack of visible commercial advertising aligns with its public service mandate.

Security posture

The website demonstrates a strong security posture with enforced HTTPS, comprehensive security headers, and browser compatibility checks to prevent outdated or insecure browsers from accessing the site. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the site lacks publicly available security policies or incident response information, which could enhance transparency and trust. GDPR compliance is evident through detailed privacy and cookie policies and a clear data protection officer contact. Overall, the security maturity is high but could benefit from formalized vulnerability disclosure and incident response documentation.

Recommendations

  1. Publish a formal vulnerability disclosure policy and security.txt file to encourage responsible reporting.
  2. Provide publicly accessible security and incident response policies to improve transparency.
  3. Regularly audit and update third-party libraries to mitigate potential vulnerabilities.
  4. Enhance contact information with verified company phone numbers and physical addresses if applicable.
  5. Continue monitoring and improving privacy compliance, especially regarding data retention and user consent mechanisms.

Technical notes

Notes

The website is built on a modern React and Next.js framework, utilizing polyfills for broad browser compatibility and Bowser for browser detection. It employs CDN-hosted static assets for performance optimization and supports multiple platforms including iOS and Android apps. The site is mobile-optimized with responsive design and accessibility considerations. SEO is supported by comprehensive meta tags and Open Graph data. Hosting details are not explicitly found, but the use of multiple arte.tv subdomains and CDNs suggests a robust hosting infrastructure. Performance is fast with asynchronous script loading and preloading strategies. Technical risks are minimal, with opportunities to formalize security documentation and improve transparency.
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.
