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 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

Relai AG positions itself as a trusted Swiss Bitcoin app with over 80,000 users, leveraging its regulatory compliance and security certifications as competitive advantages. The business model revolves around fee-based Bitcoin transactions with discounted fees via invite codes and premium services for private and business clients. The company maintains a clear focus on Bitcoin-only services, appealing to users valuing self-custody and simplicity. Partnerships with regulated service providers and integration of marketing and analytics tools support growth and user engagement.

Security posture

The website and service demonstrate a strong security posture with HTTPS enforcement, ISO 27001 certification, and Swiss regulatory compliance. The self-custodial wallet model ensures users retain control over their Bitcoin, reducing custodial risk. Security headers and encryption practices are in place, and no vulnerabilities or exposed sensitive data were detected in the analysis. However, the absence of explicit privacy policies, terms of service, and incident response contacts on the website are areas for improvement to enhance transparency and compliance.

Recommendations

  1. Publish comprehensive privacy and cookie policies prominently linked on the website.
  2. Add clear terms of service and user agreements to clarify legal and operational terms.
  3. Provide explicit contact information for security incidents and data protection inquiries.
  4. Implement and publish a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  5. Regularly review and audit third-party scripts and tracking tools to minimize privacy risks.

Technical notes

Notes

The website is built on WordPress with a modern tech stack including jQuery, Google Tag Manager, and SEO plugins like Rank Math. It uses multilingual support via WPML and integrates marketing and analytics tools such as HubSpot, Intercom, and Ahrefs Analytics. The site is well-optimized for mobile devices and performance, with fast loading times and accessibility features. The use of HTTPS and security headers indicates good security hygiene. Hosting provider details are not explicit but the infrastructure supports a professional and scalable web presence.
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.
