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

Gnosis Chain is a community-driven Ethereum sidechain project focused on providing a decentralized, low-cost, and stable blockchain environment for developers, validators, and DAO participants. The platform emphasizes credible neutrality and resilience, supported by a geographically diverse validator set and a strong community governance model via the GnosisDAO. The website reflects a mature ecosystem with developer tools, staking opportunities, and active governance proposals, positioning Gnosis Chain as a significant player in the blockchain infrastructure space. Technically, the website is built on Webflow CMS with modern web technologies including Google Fonts, jQuery, and Google Analytics for tracking. It leverages CDN hosting for performance and includes dynamic data fetching from trusted APIs to display real-time token prices and governance metrics. The site is mobile optimized and SEO friendly, providing a good user experience. From a security perspective, the site enforces HTTPS and uses cookie consent mechanisms, but lacks explicit security headers and published security policies or incident response information. No vulnerabilities or exposed sensitive data were detected in the HTML content. The WHOIS data is missing, which slightly reduces trust but is not uncommon in blockchain projects. Overall, the security posture is solid but could be improved with additional transparency and security best practices. The overall risk assessment is moderate-low with recommendations to enhance security headers, publish security policies, and provide clear contact channels for incident response. The website is professional, trustworthy, and safe for general audiences, with no adult or questionable content detected.

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

2 findings 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
    • 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

Gnosis Chain operates in the blockchain technology sector, targeting developers, validators, and decentralized autonomous organization (DAO) participants. Its competitive advantage lies in its community ownership model, credible neutrality, and early mover status as one of the first Ethereum sidechains. The business model revolves around providing blockchain infrastructure, staking services, and governance via the GNO token. Revenue streams likely include staking fees, ecosystem partnerships, and developer tool integrations. The company maintains a strong partnership ecosystem with wallet providers, swap platforms, and payment card services. Growth indicators include active governance proposals, a vibrant community forum, and continuous ecosystem expansion. The website content and linked domains reflect a well-established operation with strategic partnerships and a clear market position.

Security posture

The website demonstrates a good security maturity level with HTTPS enforced and no visible sensitive data exposure. The use of cookie consent with opt-in aligns with privacy best practices. However, the absence of explicit security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options is a gap. There is no published security policy or incident response information, which limits transparency and readiness perception. No vulnerability disclosure or security.txt file is present. The WHOIS data absence is a minor concern but common in privacy-conscious blockchain projects. Overall, the security posture is solid but could benefit from enhanced transparency, formal policies, and improved HTTP security headers to mitigate risks and build trust.

Recommendations

  1. Implement and publish a comprehensive security policy and incident response plan on the website.
  2. Add standard security HTTP headers including CSP, HSTS, and X-Frame-Options to enhance protection.
  3. Establish a vulnerability disclosure program and publish a security.txt file to facilitate responsible reporting.
  4. Provide clear security contact information or dedicated channels for incident reporting and response.
  5. Regularly audit third-party scripts and dependencies to ensure no vulnerable libraries are used.

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.
