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

Gulli.fr is a French media website focused on providing free streaming of cartoons, series, films, and children's shows. It targets a young audience and families, offering video content, games, news, and mobile applications. The site is well-branded and consistent with the Gulli media brand, a known player in French children's entertainment. Technically, the site uses modern web technologies including Next.js and React, with mobile optimization and integration of Google Tag Manager for analytics and a privacy consent SDK for cookie management. Security posture is moderate with HTTPS enabled but lacks explicit security headers and published privacy or terms of service pages. WHOIS data is not publicly available, typical for French domains managed by AFNIC, but the domain appears legitimate and consistent with the business. Overall, the site is professional and safe for its target audience but could improve transparency and security practices.

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

5 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: Google Analytics, Facebook, Twitter, YouTube

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

  2. 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.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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

Gulli.fr operates in the media sector, specifically children's entertainment in France. It leverages free streaming content supported likely by advertising and brand promotion of its mobile apps. The site links heavily to M6.fr, a major French media group, indicating a partnership or content sharing relationship. The business model focuses on engaging children and families with branded content and interactive features like games and news. The platform's market position is strong within French children's media, supported by a large content library and mobile presence. Growth opportunities include expanding content offerings and improving compliance and security transparency. The partnership ecosystem includes major French media players and app stores.

Security posture

The website enforces HTTPS and uses a privacy consent SDK, which are positive security indicators. However, it lacks visible security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options, which are recommended to mitigate common web attacks. No contact information for incident response or vulnerability disclosure is published, limiting transparency in security management. No exposed sensitive data or vulnerable libraries were detected in the HTML content. The site should enhance its security posture by implementing recommended headers, publishing privacy and terms policies, and providing clear security contact channels to improve trust and compliance.

Recommendations

  1. Implement and publish a comprehensive privacy policy and terms of service pages accessible from the homepage.
  2. Add security headers including CSP, HSTS, and X-Frame-Options to enhance protection against common web vulnerabilities.
  3. Provide clear contact information for general inquiries and security incident reporting, including a dedicated security or abuse email.
  4. Establish and publish a vulnerability disclosure policy or security.txt file to encourage responsible reporting of security issues.
  5. Improve accessibility features to ensure compliance with standards and enhance user experience for all visitors.

Technical notes

Notes

The website is built using Next.js, a React framework, indicating a modern and scalable infrastructure. It uses JavaScript and CSS with optimized image loading and responsive design for mobile devices. Google Tag Manager is integrated for analytics, and a privacy consent SDK manages cookie consent. The site performance is moderate with preloading and prefetching techniques observed. No CMS or hosting provider details were detected in the HTML snippet. The technical implementation is solid but could benefit from enhanced security headers and improved accessibility compliance to reduce technical debt and risks.
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.
