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. 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. 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.

Dark web exposure

Add-on

Leaked records that mention zondax.ch, from OffSeq Breach.

No leaked records found

Breach holds no records for zondax.ch right now. New leaks arrive continuously, so monitoring on Breach alerts you if that changes.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

Zondax positions itself as an innovator in the blockchain technology sector, offering specialized software engineering services. Their business model revolves around delivering tailored blockchain solutions with a focus on quality and innovation. The company maintains an active presence on key social platforms such as GitHub, LinkedIn, and Twitter, which supports community engagement and credibility. While no explicit revenue streams or parent/subsidiary relationships are disclosed, the company's medium size and Swiss location suggest a stable operational base. The lack of visible certifications or vulnerability disclosure programs indicates areas for potential growth in trust and compliance.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and multiple security headers present, reducing common web vulnerabilities. The presence of a cookie consent banner indicates awareness of privacy regulations such as GDPR. However, the absence of a published security policy, incident response contacts, or vulnerability disclosure mechanisms suggests room for improvement in transparency and incident readiness. No vulnerabilities or exposed sensitive data were detected in the HTML content. Overall, the security posture is solid but could be enhanced by formalizing security governance documentation and communication channels.

Recommendations

  1. Publish a dedicated security policy page outlining security frameworks and practices.
  2. Implement and publicize a vulnerability disclosure program or security.txt file.
  3. Provide clear incident response contact information, such as security@ or abuse@ email addresses.
  4. Enhance advertising transparency by disclosing any third-party marketing or tracking tools if used.
  5. Continue to maintain and update privacy and cookie policies to ensure ongoing GDPR compliance.

Technical notes

Notes

The website leverages a modern React-based framework (Next.js) combined with Material UI for styling, resulting in a responsive and visually appealing design. Hosting appears to be on Vercel, which supports fast content delivery and scalability. The site includes proper meta tags for SEO and social sharing (Open Graph and Twitter cards). Accessibility features are present but could be further audited for compliance standards. No CMS was detected, indicating a custom or static site approach. Performance is optimized with preloading of fonts and images. No legacy or vulnerable libraries were identified in the provided scripts.
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.
