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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • 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

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.

Business context

Business profile

Chorus One operates in the technology and finance sectors, focusing on crypto staking infrastructure and services. Their business model revolves around providing staking integrations, validator infrastructure, and rewards reporting to institutional clients. The company has a medium size footprint with a global reach, evidenced by its support for 50+ networks and partnerships with industry leaders. Revenue streams likely include staking fees, infrastructure services, and investment fund management. The target customers are institutional investors and digital asset companies seeking reliable staking solutions. Growth indicators include active research publications, a dedicated ventures fund, and expanding network support. The partnership ecosystem includes major crypto platforms and service providers, enhancing their market credibility and reach.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and a comprehensive cookie consent mechanism aligned with GDPR. No exposed sensitive data or vulnerable libraries were detected. However, the absence of a dedicated security policy page, incident response contacts, and vulnerability disclosure policy are gaps that could be addressed to enhance transparency and readiness. Security headers are not explicitly visible in the HTML but may be configured at the server level. The use of privacy protection in WHOIS is standard for the industry and does not raise concerns. Overall, the security maturity is good but can be improved by publishing explicit security documentation and policies.

Recommendations

  1. Implement and publicly document security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  2. Publish a dedicated security policy page including incident response procedures and contact channels.
  3. Establish and publish a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Regularly audit third-party scripts and dependencies to ensure no vulnerabilities are introduced.
  5. Enhance transparency on GDPR compliance by providing detailed data protection officer contact information and data retention policies.

Notes

The website is built using Webflow CMS, leveraging modern JavaScript libraries such as jQuery, Swiper.js, and Finsweet Attributes for enhanced UI/UX. It integrates analytics tools including Google Analytics, Microsoft Clarity, and Twitter conversion tracking, managed via Google Tag Manager. Hosting and DNS are managed through Cloudflare, providing performance and security benefits. The site is mobile-optimized with responsive design and accessibility considerations. Performance is fast with efficient resource loading. Technical risks are minimal, though reliance on multiple third-party scripts requires ongoing monitoring. The site demonstrates a modern, scalable infrastructure suitable for its institutional audience.
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.
