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

Luanti is an open source voxel game engine project with a strong community focus, offering multiple games, modding capabilities, and multiplayer support. The website serves gamers, developers, and educators by providing downloads, documentation, and community resources. The project is positioned as a niche open source alternative in the voxel gaming space with a consistent brand and active development presence. Technically, the website uses modern web technologies including HTML5, CSS3, JavaScript, and Lua for the game engine API. It supports multiple platforms including Windows, macOS, Linux variants, BSDs, and Android. The site is moderately performant, mobile-optimized, and SEO-friendly, though accessibility could be improved. Analytics are handled via Piwik/Matomo, indicating moderate user tracking. Security posture is good with HTTPS enforced and no visible vulnerabilities or sensitive data exposure. However, the site lacks important security headers and cookie consent mechanisms, which are recommended for improved security and privacy compliance. The absence of WHOIS data reduces domain trust verification, though the website content and community presence support legitimacy. Overall, the site is professional, trustworthy, and safe for general audiences. Strategic improvements in security headers, privacy compliance, and verified contact information would enhance trust and compliance.

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

5 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 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';…

  2. 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

    • 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

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

Luanti operates as a small, community-driven open source project in the technology sector, focusing on voxel game engine development. Its business model revolves around open source software distribution, community contributions, and mod ecosystem support. The project targets gamers, developers, and educators interested in voxel-based games and modding. The presence of a dedicated ContentDB and active forums indicates a strong community and partnership ecosystem. Growth is indicated by regular releases and active GitHub development. The lack of commercial advertising or payment processing suggests a non-commercial or donation-supported model.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and no exposed sensitive data. The use of Piwik/Matomo analytics is privacy-conscious compared to mainstream trackers. However, missing security headers such as Content-Security-Policy and X-Frame-Options reduce defense-in-depth. The absence of cookie consent and privacy compliance mechanisms is a gap, especially for GDPR. No incident response or security policy information is published, limiting transparency. The lack of WHOIS data reduces domain trust verification. Overall, the security posture is good but can be improved with standard headers, privacy enhancements, and published security policies.

Recommendations

  1. Implement standard security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  2. Add a cookie consent banner and cookie policy to comply with GDPR and other privacy regulations.
  3. Publish a dedicated security policy and incident response contact information to improve transparency and trust.
  4. Provide verified company contact information including emails and phone numbers for business and security inquiries.
  5. Verify and publish domain registration details or use registrar RDDS services to improve domain trustworthiness.

Technical notes

Notes

The website is built with modern web standards using HTML5, CSS3, and JavaScript. It integrates Lua scripting for the game engine API and uses Piwik/Matomo for analytics. The site is mobile-optimized and SEO-friendly with proper meta tags and Open Graph data. Performance is moderate with deferred script loading. No CMS detected, likely a static or custom-built site. Hosting provider is not identified. Technical debt is low, but accessibility features could be enhanced. The absence of security headers is a technical risk that should be addressed to improve security posture.
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.
