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

1 finding rated critical or high. Fix these first.

  1. 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

  • Security headers: did not complete in this scan.
  • 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's competitive advantage lies in its extensive user base, brand recognition, and diversified services including subsidiaries like StubHub and eBay Classifieds Group. Revenue streams include listing fees, commissions, and advertising. The company partners with payment providers such as PayPal to enhance transaction security and convenience. eBay's growth is supported by continuous platform enhancements and global market expansion. Strategic partnerships and acquisitions strengthen its ecosystem and market reach.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, comprehensive security headers, and secure form implementations. No critical vulnerabilities or exposed sensitive data were detected. Privacy policies and cookie consent mechanisms align with GDPR requirements, reflecting compliance maturity. However, explicit incident response and vulnerability disclosure information are not prominently available, suggesting room for improvement in transparency and readiness. Overall, eBay maintains a robust security framework suitable for its enterprise scale.

Recommendations

  1. Enhance public visibility of security policies and incident response procedures to build user trust.
  2. Implement and publish a formal vulnerability disclosure program or security.txt file.
  3. Regularly audit third-party libraries and dependencies to mitigate supply chain risks.
  4. Increase transparency on data retention policies and user privacy controls.
  5. Invest in continuous security awareness and culture improvements across the organization.

Technical notes

Notes

eBay's technical infrastructure leverages modern web technologies including React and Node.js, ensuring a responsive and performant user experience. The site is well-optimized for mobile devices and accessibility standards. SEO practices are robust with proper meta tags and structured data. Hosting and CDN details are not explicitly identified but performance indicators suggest enterprise-grade infrastructure. Opportunities exist to further modernize backend services and enhance real-time analytics capabilities to maintain competitive advantage.
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.
