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

Ethereum.org is the official community-driven website providing comprehensive educational resources, developer tools, and ecosystem information for the Ethereum blockchain platform. It serves a broad audience including developers, crypto users, enterprises, and the general public interested in blockchain technology. The site is well-positioned as a leading platform in the blockchain and decentralized finance sectors, offering key services such as wallet finders, developer documentation, and ecosystem exploration. Technically, the website is built using modern technologies including React and Next.js, with a focus on performance, mobile optimization, and accessibility. The use of Matomo analytics reflects a privacy-conscious approach to user tracking. Security-wise, the site enforces HTTPS and has domain transfer protections, but lacks DNSSEC and explicit security or incident response policies. Privacy compliance is limited due to the absence of visible privacy and cookie policies. Overall, the website demonstrates a high level of professionalism and trustworthiness, with minor gaps in privacy and security policy disclosures.

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 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 Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  3. 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

Ethereum.org operates as an essential entity in the blockchain technology sector, focusing on open-source community engagement and education. Its business model revolves around providing free resources and tools to foster adoption and development of Ethereum-based applications. The platform benefits from a large and active developer community, strategic partnerships, and a strong brand presence. Revenue streams are indirect, likely supported by ecosystem growth and associated services. The target customer segments include developers, enterprises, and end-users of decentralized applications. Growth indicators include continuous content updates, community involvement, and ecosystem expansion. The partnership ecosystem includes events like Devconnect and links to official social channels, enhancing community engagement and collaboration.

Security posture

The security posture of ethereum.org is solid with HTTPS enforced and domain transfer protections in place. However, the absence of DNSSEC and lack of published security or incident response policies represent areas for improvement. No vulnerabilities or exposed sensitive data were detected in the content. The site uses Matomo for analytics, which is privacy-friendly compared to other trackers. The lack of a security.txt file or dedicated vulnerability disclosure page limits transparency for security researchers. Overall, the site shows a mature security approach but could enhance its compliance and incident readiness documentation.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Publish a comprehensive privacy policy and cookie policy with explicit consent mechanisms to improve GDPR compliance.
  3. Create and publish a security policy and incident response plan accessible to users and security researchers.
  4. Implement a security.txt file to facilitate responsible vulnerability disclosure.
  5. Add clear contact information for security incidents and general inquiries to improve trust and communication.

Notes

The website is built on a modern React and Next.js stack, ensuring fast performance and excellent mobile responsiveness. The use of preloaded fonts and optimized images contributes to efficient loading times. Accessibility features such as skip links and focus outlines are present, enhancing usability.

Hosting details are not explicit, but domain registration is stable and long-term. The site uses Matomo analytics, indicating a preference for privacy-respecting tools. No CMS is detected, suggesting a custom or static site generation approach. Overall, the technical infrastructure is robust with minor opportunities for security enhancements.
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.
