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

10 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

  2. 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

      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

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

The club operates in the sports sector as a small-sized entity focused on basketball activities in the local French community. Its competitive advantage lies in community engagement and providing up-to-date information on matches and team activities. The business model is non-commercial or community-based, with revenue likely from memberships or local sponsorships. The website supports growth by maintaining social media presence on Facebook and Instagram, enhancing outreach. No partnerships or subsidiaries were identified. The club appears newly established or recently digitalized, as indicated by the recent domain registration. Strategic observations include the need for formalized privacy and security policies to build trust and comply with regulations.

Security posture

The website demonstrates a basic security posture with HTTPS enabled and domain registration protections such as clientTransferProhibited and clientDeleteProhibited status flags. However, the absence of security headers like Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security reduces its defense-in-depth. No vulnerabilities or exposed sensitive data were detected in the provided content. The lack of privacy and cookie policies indicates compliance gaps with GDPR and related regulations. Incident response and vulnerability disclosure mechanisms are not present, limiting readiness for security incidents. Overall, the security maturity is moderate but can be significantly improved by implementing recommended headers, policies, and incident response contacts.

Recommendations

  1. Implement comprehensive privacy and cookie policies with clear GDPR compliance statements.
  2. Add security headers including Content-Security-Policy, X-Content-Type-Options, X-Frame-Options, and Strict-Transport-Security to enhance protection.
  3. Establish an incident response contact channel and publish vulnerability disclosure information.
  4. Conduct regular security audits of third-party scripts and dependencies to identify and mitigate vulnerabilities.
  5. Enhance accessibility features and SEO optimization to improve user experience and search visibility.

Technical notes

Notes

The website is built on Angular 20.3.1 framework, utilizing Material Design components and Google Fonts for typography. Google Maps API is integrated for location services. The hosting provider is OVH, a reputable European hosting company. The site uses modern CSS with Tailwind utility classes and is mobile responsive. Performance is moderate, with no explicit performance optimization scripts detected. No CMS is identified, suggesting a custom or SPA architecture. The site lacks analytics or tracking scripts, indicating minimal user data collection. Technical debt appears low, but the absence of security headers and privacy mechanisms indicates areas for modernization and compliance improvements.
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.
