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

7 findings rated critical or high. Fix these first.

  1. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  2. 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • 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';…

  3. 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

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

The 3MF Consortium operates as an essential industry consortium focused on additive manufacturing technology standards. Its business model revolves around collaboration among major technology and manufacturing companies to develop open, standardized file formats that facilitate interoperability and innovation in 3D printing. The consortium's market position is strong, supported by ISO standardization and partnerships with leading industry players. Revenue streams likely include membership fees and sponsorships. The target customers include software developers, hardware manufacturers, and industrial users of additive manufacturing technologies. The consortium maintains a robust partnership ecosystem and actively promotes adoption through resources, specifications, and community engagement.

Security posture

The website exhibits a moderate to good security maturity level. HTTPS is properly implemented, and domain registration includes clientTransferProhibited status, reducing risk of unauthorized domain transfers. However, DNSSEC is not enabled, which is a recommended best practice for DNS security. The absence of a Content Security Policy and other security headers like X-Content-Type-Options and X-Frame-Options indicates room for improvement. No vulnerability disclosure or security policy pages were found, which could hinder incident response readiness. No exposed sensitive data or vulnerable libraries were detected. Overall, the security posture is adequate but could be enhanced to align with industry best practices and compliance requirements.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Implement a comprehensive Content Security Policy and additional security headers to mitigate common web vulnerabilities.
  3. Publish a dedicated security policy and vulnerability disclosure page to improve transparency and incident response.
  4. Add explicit cookie consent mechanisms and update privacy policies to reflect GDPR and other privacy regulations compliance.
  5. Enhance accessibility features to improve usability for all users and comply with accessibility standards.

JavaScript libraries include jQuery and New Relic for performance monitoring. The site loads external resources from trusted domains and uses Google Analytics for visitor tracking. Performance is moderate with good mobile responsiveness and SEO optimization. The technical infrastructure is modern but could benefit from improved security headers and DNS configurations. The hosting and domain registration are managed by reputable providers, ensuring stability and reliability. Overall, the technical implementation supports the business goals effectively with minor areas for 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.
