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. 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
    • 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

eBay España benefits from the global brand strength of eBay Inc., operating in the e-commerce sector with a marketplace business model that connects buyers and sellers. Its competitive advantage lies in its extensive user base, secure transaction mechanisms, and integrated payment partnerships such as PayPal. Revenue streams include listing fees, final value fees, and advertising. The platform serves a wide demographic, from individual consumers to small businesses. Strategic partnerships and a comprehensive digital marketing ecosystem support growth and customer engagement. The company maintains consistent branding and content quality, reinforcing its market leadership in Spain's online retail space.

Security posture

The website exhibits a strong security posture with enforced HTTPS, comprehensive security headers including CSP and HSTS, and secure input handling in forms. No exposed sensitive data or vulnerable libraries were detected. However, the absence of a publicly visible vulnerability disclosure program and limited incident response contact information suggest areas for improvement. The presence of a data protection officer contact indicates compliance with data protection regulations. Overall, the security maturity is high, suitable for an enterprise-level e-commerce platform, but could benefit from enhanced transparency and proactive vulnerability management.

Recommendations

  1. Establish and publicize a formal vulnerability disclosure program to encourage responsible reporting.
  2. Enhance visibility and accessibility of incident response and abuse contact channels.
  3. Regularly audit and update third-party libraries to mitigate emerging vulnerabilities.
  4. Expand security policy documentation and make it easily accessible to users.
  5. Implement continuous security awareness and training programs to strengthen security culture.

Technical notes

Notes

The website is built on a modern technology stack including React and Node.js, with integration of popular analytics and marketing tools. The site is well-optimized for performance and mobile responsiveness, providing a seamless user experience. Accessibility features are present but could be further enhanced to meet higher standards. SEO practices are good with proper meta tags and structured data usage. Hosting details are not explicitly identified but the site benefits from robust infrastructure supporting fast load times and high availability. Technical risks are minimal, with opportunities for modernization focused on accessibility and security 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.
