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. 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

  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

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

21.co operates in the intersection of finance and blockchain technology, offering wrapped tokens that enable cross-chain liquidity access. Their business model leverages institutional custody and proprietary technology to mint and burn tokens backed 1:1 by underlying assets. The company collaborates with partners like 21Shares, Index Coop, and Alongside, integrating their tokens into broader crypto market products. Their target customers are institutional and sophisticated crypto users requiring secure, compliant token solutions. The company demonstrates growth potential through expanding token offerings and partnerships. The website content and structure indicate a focus on transparency, security, and regulatory compliance, which are critical in the financial services sector. The lack of public WHOIS data is mitigated by strong on-site trust indicators and professional presentation.

Security posture

The website exhibits a mature security posture with HTTPS enforced, comprehensive security headers, and no visible vulnerabilities. The mint and burn processes for tokens are centralized and controlled via the Onyx OS, adding a layer of operational security. Third-party audits by Halborn and Chainlink proof of reserves enhance trust. However, the absence of a published security policy, incident response plan, or vulnerability disclosure program limits transparency in security governance. No contact channels specifically for security incidents or abuse are provided. Privacy compliance is well managed with cookie consent and GDPR-aligned policies. Overall, the security posture is strong but could be improved by publishing formal security governance documents and incident response contacts.

Recommendations

  1. Publish a dedicated security policy and incident response plan on the website to enhance transparency and trust.
  2. Implement and publicize a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  3. Provide contact information for security incidents or abuse reporting to improve incident response readiness.
  4. Consider publishing data protection officer contact details to strengthen GDPR compliance signals.
  5. Continue expanding token offerings with ongoing security audits and maintain clear communication of security practices.

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.
