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

Athletic Club operates a comprehensive official website serving as the primary digital presence for the historic football club based in Bilbao, Spain. The site offers extensive content including latest news, team rosters, ticket sales for matches and tours, official merchandise stores, and membership information. It targets football fans, club members, and tourists interested in the club's activities and heritage. The business model revolves around fan engagement, ticketing, merchandising, and exclusive experiences, positioning Athletic Club as a prominent sports entity with a large and loyal audience. Technically, the website leverages modern web technologies such as the Astro framework, Google Tag Manager, Microsoft Clarity, and Cookiebot for analytics and privacy compliance. The site is well-optimized for mobile devices, features good accessibility practices, and maintains strong SEO fundamentals. Performance is fast, and the site structure supports multilingual content in Spanish, Basque, and English, enhancing its reach. From a security perspective, the site enforces HTTPS with excellent SSL configuration and implements multiple security headers to protect users. Privacy compliance is robust with clear cookie consent mechanisms and a comprehensive privacy policy. However, there is a lack of publicly available security policies or incident response contacts, which could be improved to enhance transparency and trust. Overall, Athletic Club's website demonstrates a mature digital presence with strong business credibility and security posture. The domain is privacy protected, which is typical and justified for this type of organization. The site is trustworthy, professional, and well-maintained, supporting the club's brand and operational goals effectively.

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

4 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 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

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook, Twitter, LinkedIn, YouTube

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

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

Athletic Club holds a strong market position as a historic and regionally significant football club with a large fanbase. Its competitive advantage lies in its unique cultural identity and loyal supporters. The business model focuses on multiple revenue streams including ticket sales, merchandise, memberships, and VIP experiences. The target customers are sports fans, local and international tourists, and club members. Growth indicators include active content updates, expansion of digital services like nutrition apps and football experiences, and partnerships with related domains. The club maintains a broad partnership ecosystem with official stores, foundation, and stadium-related services, reflecting a well-integrated operational structure.

Security posture

The website exhibits a high level of security maturity with enforced HTTPS, comprehensive security headers, and no visible exposure of sensitive data. Privacy compliance is well addressed through cookie consent and privacy policies aligned with GDPR. However, the absence of a dedicated security policy page and incident response contact information indicates room for improvement in transparency and readiness. No vulnerabilities or outdated libraries were detected in the analysis. The site’s security posture supports business continuity and user trust effectively but would benefit from formalizing vulnerability disclosure and incident response mechanisms.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and user protections.
  2. Provide clear incident response contact information to facilitate reporting of security issues.
  3. Implement a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  4. Enhance contact information availability, including official emails and phone numbers for support.
  5. Continue monitoring and updating third-party scripts and libraries to mitigate emerging vulnerabilities.

Technical notes

Notes

The website is built using the Astro framework, which supports modern, performant web applications. It integrates Google Tag Manager and Microsoft Clarity for analytics and user behavior tracking, alongside Cookiebot for cookie consent management. The site is mobile-optimized with responsive design and accessibility features. SEO is supported by proper meta tags, Open Graph, and Twitter cards. The hosting provider is not explicitly identified, but the site uses HTTPS with strong SSL configuration. Performance is fast with efficient resource loading. There is no detected CMS, suggesting a custom or static site generation approach. Technical risks are minimal, but continuous updates and monitoring of third-party scripts are recommended to maintain security and performance.
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.
