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

eBay Inc. operates one of the world's largest online marketplaces, connecting millions of buyers and sellers globally. The platform offers a diverse range of products including electronics, fashion, collectibles, and more, supporting both auction-style and fixed-price sales. eBay holds a strong market position as a trusted e-commerce leader with a well-established brand since 1995. The website is professionally designed, mobile-optimized, and provides a seamless user experience for a general audience. Technically, eBay's website leverages modern web technologies such as React and Node.js, ensuring fast performance and good accessibility. The site employs robust security measures including HTTPS, comprehensive security headers, and secure form handling. Privacy compliance is well addressed with detailed privacy and cookie policies, including GDPR adherence and user consent mechanisms. The security posture is strong with no evident vulnerabilities or exposed sensitive data. However, the WHOIS data is not publicly available due to privacy protection, which is justified given the enterprise nature of the business.

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 market positioning as a leading global e-commerce platform is supported by its extensive product offerings and strong brand recognition. The business model focuses on facilitating consumer-to-consumer and business-to-consumer transactions, generating revenue through listing fees, commissions, and payment processing partnerships such as with PayPal. Target customers range broadly from individual consumers to small businesses worldwide. The company has strategic subsidiaries like StubHub and a broad partnership ecosystem. Growth indicators include continuous platform enhancements and global market expansion. eBay's operations reflect a mature and scalable e-commerce ecosystem with a focus on trust and user protection.

Security posture

The website exhibits a high level of security maturity with enforced HTTPS, strong security headers including Content Security Policy, and secure handling of user inputs in forms.

Technical notes

Notes

eBay's technical infrastructure is built on modern web technologies including React and Node.js, supporting a responsive and performant user experience. The site is well-optimized for mobile devices and accessibility standards. SEO practices are comprehensive with proper meta tags and structured data. Hosting details are not explicitly disclosed but performance indicators suggest a robust hosting environment. The website uses multiple external domains for content delivery and analytics, including trusted partners like PayPal and Google Analytics. Technical risks are minimal, with opportunities for modernization focused on enhanced security transparency and incident response capabilities.
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.
