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

Tameteo.com, operated by Meteored, is a well-established online weather forecasting platform targeting French-speaking users primarily in France and its overseas territories. The site offers comprehensive 14-day weather forecasts, hourly updates, radar and satellite imagery, and weather-related news. It supports multiple platforms including web and mobile apps for Android, iOS, Huawei, and Windows, enhancing accessibility and user engagement. The business model relies on free content supported by advertising and additional services such as widgets and plugins for third-party integration. Technically, the website employs modern JavaScript frameworks and libraries, integrates Google Tag Manager and Google Ads for analytics and advertising, and uses a Consent Management Platform to comply with GDPR. The site is mobile-optimized with good SEO practices and moderate performance. Security posture is solid with HTTPS enforced and GDPR compliance evident, though some security headers could be improved. Despite the professional appearance and comprehensive content, the absence of WHOIS registration data raises concerns about domain legitimacy and transparency. No direct company contact emails or phone numbers are publicly available, which may impact business credibility. Overall, the site is trustworthy and functional but would benefit from improved domain registration transparency and enhanced security headers. Strategic recommendations include implementing additional security headers, enhancing accessibility features, and providing clearer business contact information to strengthen trust and 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

5 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 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

  3. 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 SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

Tameteo.com holds a strong market position as a media company specializing in weather forecasting for France and francophone audiences. Its competitive advantage lies in detailed, reliable forecasts combined with rich multimedia content and multi-platform availability. Revenue streams are primarily advertising-based, supplemented by app downloads and widget/plugin offerings. The target customers are general public users interested in weather information, including outdoor enthusiasts and professionals needing accurate forecasts. The company maintains an active social media presence and partners with sister sites in other languages and regions, indicating a broad partnership ecosystem. Growth indicators include continuous content updates, app availability, and GDPR compliance, reflecting operational maturity and market awareness.

Security posture

The website demonstrates a mature security posture with mandatory HTTPS encryption and a robust GDPR consent mechanism. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the lack of explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options suggests room for improvement. Incident response and security policy information are not publicly disclosed, which may limit transparency. The site uses multiple third-party scripts for advertising and analytics, necessitating regular security audits to mitigate supply chain risks. Overall, the security maturity is good but could be enhanced by adopting additional best practices and publishing security policies.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web attacks.
  2. Publish a clear security policy and incident response contact information to improve transparency and trust.
  3. Enhance accessibility compliance to meet WCAG standards for broader user inclusivity.
  4. Provide verified company contact emails and phone numbers on the website to strengthen business credibility.
  5. Investigate and resolve the missing WHOIS registration data to ensure domain legitimacy and reduce suspicion.

Technical notes

Notes

The website uses a modern JavaScript-based front-end with asynchronous loading of scripts and stylesheets to optimize performance. It integrates Google Tag Manager and Google Ads GPT for advertising and analytics, along with Prebid.js for header bidding. Leaflet.js is used for interactive maps. The site is served over HTTPS with Cloudflare Insights for performance monitoring. Mobile optimization is good with responsive design and app availability across major platforms. No CMS was explicitly detected, suggesting a custom or proprietary platform. Performance is moderate, with potential improvements in script loading and caching. The technical infrastructure supports a rich user experience but requires ongoing maintenance to manage third-party dependencies and security.
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.
