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

Grayscale is a leading digital asset-focused investment platform, positioning itself as the largest in the world within this niche. The company offers investment products that allow investors to gain exposure to disruptive blockchain and cryptocurrency technologies. The website reflects a mature digital presence with a professional design, modern technology stack including React and Next.js, and integration of Google Tag Manager for analytics. However, the absence of WHOIS registration data raises concerns about domain registration transparency. Security posture is generally good with HTTPS enabled, but lacks visible security headers and explicit privacy or cookie policies. Contact information and incident response details are not clearly presented, which could impact user trust and compliance. Overall, the website is safe, well-designed, and targeted at investors interested in digital assets, but improvements in privacy compliance and domain transparency are recommended.

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

5 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • 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 Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • 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 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

Grayscale operates in the finance sector, specifically focusing on digital asset investments. Its market position as the largest platform in this space suggests significant market share and influence. The business model revolves around providing investment products that transform emerging technologies into accessible investment opportunities. The target audience includes institutional and retail investors seeking exposure to cryptocurrencies. The company leverages modern web technologies and analytics tools to optimize user experience and marketing efforts. However, the lack of publicly available WHOIS data and absence of detailed privacy and contact information may affect perceived credibility. Strategic partnerships and certifications are not explicitly listed, indicating potential areas for business development and trust enhancement.

Security posture

The website employs HTTPS, ensuring encrypted communications, which is a fundamental security requirement. However, no explicit security headers such as Content Security Policy (CSP), X-Frame-Options, or HSTS were detected, which are recommended to mitigate common web vulnerabilities. There is no evidence of exposed sensitive data or vulnerable libraries in the provided content. The absence of privacy and cookie policies, as well as incident response contacts, suggests gaps in compliance and security transparency. The use of Google Tag Manager indicates tracking capabilities, but privacy compliance appears weak. Overall, the security posture is moderate with room for improvement in headers, policies, and incident response readiness.

Recommendations

  1. Implement comprehensive privacy and cookie policies with clear GDPR compliance statements.
  2. Add and configure security headers such as CSP, HSTS, X-Frame-Options, and X-Content-Type-Options.
  3. Publish clear contact information including security incident response and data protection officer contacts.
  4. Verify and update WHOIS registration data to improve domain transparency and trustworthiness.
  5. Enhance privacy compliance by providing cookie consent mechanisms and detailed data retention policies.

Technical notes

Notes

The website is built using modern JavaScript frameworks including React and Next.js, supported by Material UI for UI components. It uses Google Tag Manager for analytics and tracking. The site appears mobile-optimized with responsive design and good accessibility features. Performance is moderate, likely due to rich content and fonts preloading. No CMS or hosting provider details were identified from the content. The technical infrastructure is modern and scalable but could benefit from enhanced security configurations and privacy compliance implementations to reduce technical debt and improve trust.
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.
