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

21Shares is a leading issuer of crypto exchange-traded products (ETPs), offering a broad range of investment products for both institutional and retail investors. The company positions itself as the world's first and largest crypto ETP issuer, providing easy access to crypto assets through traditional brokerage and banking channels. Their product portfolio includes single asset ETPs, diversified index ETPs, smart index ETPs, staking products, and specialized categories such as 'Made in America' and 'Culture & Community'. The website is professionally designed, well-branded, and provides comprehensive product and market insights, targeting investors interested in regulated crypto investment vehicles. Technically, the website is built on the Webflow platform, utilizing modern web technologies including JavaScript frameworks, 3D animations via Spline, and third-party integrations such as Google Tag Manager, Hotjar, Cookiebot for consent management, and GeoTargetly for geolocation services. The site is mobile optimized with good SEO and accessibility features, although some security headers are missing. The SSL configuration is excellent, ensuring secure communications. From a security perspective, the site enforces HTTPS and implements cookie consent mechanisms aligned with GDPR requirements. However, explicit security policies, incident response contacts, and vulnerability disclosure mechanisms are not found, representing areas for improvement. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. The absence of WHOIS data for the domain raises some concerns about domain registration transparency, but the professional nature of the site and its market presence mitigate this risk. Overall, 21Shares presents a trustworthy and professional digital presence consistent with a reputable financial services company specializing in crypto investment products. Strategic recommendations include enhancing security headers, publishing explicit security and incident response policies, and improving domain registration transparency to strengthen trust further.

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 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

  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

  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

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

21Shares occupies a strong market position as a pioneer and leader in crypto ETP issuance, targeting both retail and institutional investors. Their diversified product range and partnerships with major exchanges like Nasdaq and Euronext provide competitive advantages. The business model focuses on regulated, physically-backed crypto investment products accessible via traditional financial channels, appealing to investors seeking compliant crypto exposure. The company demonstrates growth through new product launches and media presence. Their ecosystem includes partnerships with exchanges and media outlets, enhancing credibility and market reach. The website supports multiple languages and regions, indicating a global market approach. The lack of direct contact emails or phone numbers on the homepage suggests a controlled communication channel, likely via contact forms and official channels.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and cookie consent implemented, reflecting compliance with privacy regulations such as GDPR. The use of third-party consent management and analytics tools is transparent and controlled. However, the absence of explicit security headers like Content Security Policy (CSP), HSTS, and X-Frame-Options reduces the overall security hardening. No incident response or vulnerability disclosure information is provided, which is a gap in security transparency. No signs of exposed sensitive data or vulnerable libraries were found. The security score is good but could be improved by adopting best practices in HTTP headers and publishing security policies. The missing WHOIS data is a concern for domain trust but does not directly impact website security.

Recommendations

  1. Implement and publish comprehensive security headers including CSP, HSTS, and X-Frame-Options to enhance protection against common web attacks.
  2. Publish a dedicated security policy and incident response plan on the website to improve transparency and readiness.
  3. Establish a vulnerability disclosure program and provide a security.txt file to facilitate responsible reporting of security issues.
  4. Improve domain registration transparency by ensuring WHOIS data is available or clearly justified if privacy protection is used.
  5. Maintain and regularly audit third-party scripts and tracking tools to minimize privacy and security risks.

Technical notes

Notes

The website is built on the Webflow CMS platform, leveraging modern JavaScript libraries and frameworks such as Swiper.js for sliders and Spline for 3D animations. It integrates third-party services including Google Tag Manager for analytics, Hotjar for user behavior tracking, Cookiebot for cookie consent management, and GeoTargetly for geolocation-based content delivery. The site is responsive and optimized for mobile devices with fluid typography scaling. Performance is moderate, with some heavy assets like 3D scenes that may impact load times. Accessibility features are basic but present. SEO is well addressed with proper meta tags, Open Graph, and JSON-LD structured data. The technical stack is modern and suitable for a professional financial services website, though opportunities exist to optimize performance and security headers further.
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.
