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.de's business intelligence reveals a well-established e-commerce marketplace model focused on facilitating transactions between consumers and businesses. The platform's competitive advantage lies in its global brand, extensive user base, and comprehensive service ecosystem including payment processing partnerships such as with PayPal. Revenue streams primarily derive from listing fees, final value fees, and advertising. The target customer segments include general consumers and small to medium-sized businesses in Germany. Growth indicators include continuous technological enhancements and strong market penetration. The partnership ecosystem is robust, involving payment processors and advertising networks. Strategic observations highlight eBay's focus on trust, security, and compliance to maintain market leadership and customer confidence.

Security posture

The security posture of eBay.de is strong, characterized by enforced HTTPS, comprehensive security headers, and secure form handling. No exposed sensitive data or vulnerable libraries were detected in the analysis. The site follows security best practices including content security policies and secure cookie usage. However, explicit incident response contact information and security policy documentation were not found publicly, which could be improved to enhance transparency and readiness. Compliance with GDPR is evident through privacy and cookie policies. Overall, the security maturity is high, suitable for an enterprise e-commerce platform handling sensitive user data and transactions.

Recommendations

  1. Publish a dedicated security policy and incident response page to improve transparency and user trust.
  2. Provide explicit security contact channels such as security@ or abuse@ email addresses.
  3. Regularly audit third-party scripts and dependencies to prevent vulnerabilities.
  4. Enhance user education on security best practices and phishing awareness.
  5. Maintain and update privacy and cookie consent mechanisms to align with evolving regulations.

Technical notes

Notes

The website infrastructure is modern and robust, utilizing React for frontend rendering and Node.js likely for backend services. DNS is managed via NS1 with multiple authoritative name servers, indicating high availability and resilience. The site is hosted on enterprise-grade infrastructure, likely eBay's own or contracted providers. Performance is optimized with CDN usage and efficient asset loading. Mobile optimization and accessibility features are well implemented, supporting a wide user base. SEO practices are evident with proper meta tags and structured data. Technical risks are minimal, but continuous monitoring and modernization are recommended to mitigate emerging threats and technical debt.
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.
