0–100, higher is better. How it is calculated

Tcl3D is an open source software project providing 3D graphics capabilities to the Tcl scripting language by wrapping OpenGL and other 3D libraries using SWIG. The project is maintained by Paul Obermeier and has been active since 2005, positioning itself as a niche technology resource for developers interested in Tcl-based 3D programming. The website offers documentation, downloads, demos, and historical information, with source code hosted on SourceForge and additional builds available via BAWT. Technically, the site uses a modern Bootstrap framework with jQuery, delivering a responsive and user-friendly experience. However, the site lacks explicit privacy and cookie policies, which is a compliance gap. Security posture is moderate with HTTPS enabled but missing DNSSEC and security headers. No signs of tracking or advertising are present, indicating a privacy-respecting approach. Overall, the domain registration is consistent with the project's history, enhancing trustworthiness.

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

11 findings rated critical or high. Fix these first.

  1. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • Critical

      Critical Service Exposed: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

      What to do: Immediately restrict access to MySQL using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  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 Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

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 · found on this site
  • 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 project operates as a small-scale open source initiative targeting developers and enthusiasts in the Tcl and 3D graphics community. Its business model is non-commercial, focusing on software distribution under a permissive BSD license. The project leverages partnerships with SourceForge for hosting and BAWT for build automation. The lack of commercial activity and advertising suggests a community-driven approach. The website's clear structure and professional content support its credibility. Growth indicators are limited but consistent with a mature open source project. The absence of social media presence or extensive marketing tools indicates a focused, technical audience rather than mass market outreach.

Security posture

The website demonstrates a basic to moderate security maturity level. HTTPS is enabled, and domain transfer is protected, but DNSSEC is not implemented, and no security headers were detected in the provided data. There is no evidence of privacy policies, cookie consent mechanisms, or vulnerability disclosure processes, which are important for compliance and incident response readiness. The absence of exposed sensitive data and tracking scripts is positive. Overall, the security posture is adequate for a small open source project website but could be improved by adopting modern security headers, enabling DNSSEC, and publishing privacy and security policies.

Recommendations

  1. Enable DNSSEC to enhance domain name system security and prevent spoofing.
  2. Implement standard security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to mitigate common web attacks.
  3. Publish clear privacy and cookie policies to improve compliance with GDPR and other regulations.
  4. Add a vulnerability disclosure policy or security.txt file to facilitate responsible reporting of security issues.
  5. Consider adding contact emails or security contact channels explicitly on the website to improve incident response readiness.

Technical notes

Notes

The website is built using HTML5 with Bootstrap and jQuery frameworks, providing a responsive and modern user interface. The site structure is clear with well-organized navigation and content sections. Hosting is managed via RegistryGate GmbH with DNS servers at kasserver.com. Performance is moderate with no obvious technical debt or errors in the provided HTML. The absence of a CMS suggests a static or custom-generated site, likely maintained by the project owner. There is room for improvement in SEO and accessibility features. No analytics or tracking scripts were detected, aligning with the privacy-respecting stance of the site.
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.
