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. 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

  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 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
    • 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

Materii operates within the niche of Material You client applications, positioning itself as a developer-centric organization with a focus on open source projects. The organization benefits from GitHub's platform for distribution and collaboration, with a modest but engaged follower base. The lack of direct contact information and formal policies suggests a primarily community-driven approach rather than a commercial enterprise. The verified domain and GitHub verification enhance credibility. There is no evidence of partnerships or subsidiaries. The business model likely relies on community contributions and open source engagement rather than direct revenue streams.

Security posture

The website benefits from GitHub's robust security infrastructure, including HTTPS, security headers, and domain verification. No vulnerabilities or exposed sensitive data were detected in the HTML content. However, the absence of explicit security policies, incident response contacts, and vulnerability disclosure mechanisms indicates room for improvement in formal security governance. Compliance with GDPR or other privacy regulations is not evident due to missing privacy and cookie policies. Overall, the security posture is good technically but lacks documented governance and compliance artifacts.

Recommendations

  1. Publish a clear privacy policy and cookie policy to improve privacy compliance and user trust.
  2. Implement a vulnerability disclosure policy and security.txt file to formalize security incident handling.
  3. Provide contact information for security incidents and general inquiries to enhance transparency.
  4. Regularly review and update security headers and monitor dependencies for vulnerabilities.
  5. Consider adding business information and certifications to strengthen business credibility.

Technical notes

Notes

The website is hosted on GitHub and uses modern web technologies including React and GitHub's Primer design system. Performance is optimized with fast loading times and mobile responsiveness. Accessibility features are implemented to a good standard. The site uses multiple external domains primarily related to GitHub's asset delivery and CDN infrastructure. No CMS or third-party hosting providers outside GitHub were detected. The technical implementation is solid with minimal technical debt visible from the HTML content.
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.
