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 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 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

Cults3D operates on a marketplace business model, generating revenue through sales commissions, advertising, and affiliate partnerships. Its target market includes hobbyists, professionals, and DIY enthusiasts interested in digital fabrication. The platform's competitive advantage lies in its extensive community features, curated content, and broad file format support. Partnerships with filament suppliers, 3D scanner manufacturers, and filament brands enhance its ecosystem. The company maintains a consistent brand presence and leverages social media channels to engage its audience. Growth indicators include active contests, trending model features, and a large searchable database of over 2.7 million designs.

Security posture

The website enforces HTTPS with good SSL configuration and implements standard security headers such as HSTS, X-Frame-Options, and Content-Security-Policy. CSRF protection is evident via authenticity tokens in forms. Cookie consent mechanisms comply with GDPR requirements, indicating a privacy-conscious approach. However, the absence of published security policies, incident response contacts, and vulnerability disclosure programs suggests room for improvement in transparency and readiness. No critical vulnerabilities or exposed sensitive data were detected in the content. The lack of DNSSEC is a minor security gap. Overall, the security posture is solid but could benefit from enhanced documentation and proactive disclosure.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  2. Publish a dedicated security policy and incident response plan accessible to users and researchers.
  3. Implement and publicize a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  4. Provide explicit contact information for security incidents, such as security@ or abuse@ email addresses.
  5. Regularly audit and update third-party scripts and advertising integrations to minimize risk exposure.

Technical notes

Notes

The website is built on a robust Ruby on Rails framework with modern frontend technologies and integrates advanced search via Typesense. It uses multiple third-party advertising and analytics services, including Google Tag Manager, Amazon Ads, and InMobi CMP, indicating a mature marketing infrastructure. The site is well-optimized for performance and mobile responsiveness, with good SEO practices and accessibility features. Hosting is managed by OVH sas with Cloudflare DNS, providing reliable infrastructure. The use of modulepreload and async script loading enhances page load speed. There is no evidence of technical debt or deprecated technologies, suggesting ongoing maintenance and modernization.
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.
