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

lua-users.org is a niche community-driven website dedicated to users and developers of the Lua programming language. It provides collaborative resources such as a wiki, mailing list archives, and informational pages to support the Lua user community. The site is small in scale and primarily serves as an informational hub rather than a commercial entity. Technically, the website is basic, using simple HTML and CSS without modern frameworks or CMS. It is hosted by pair Networks, a reputable hosting provider, and the domain has been active since 2001, indicating a stable presence in the Lua community. However, the site lacks modern security features such as HTTPS and security headers, and no privacy or cookie policies are present, which limits its compliance with current web standards and regulations. There are no forms or contact details available, which reduces user engagement and support capabilities. Overall, the website is functional but could benefit from modernization and improved security and privacy practices.

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

9 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.

    • Critical

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

  2. 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

  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.

    • Critical

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

  4. 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"

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 website operates as a community resource for Lua programming language users, targeting developers and enthusiasts. Its business model is non-commercial, focusing on collaborative content and archival services. The site holds a niche market position within the Lua programming ecosystem but lacks monetization or partnership indicators. The absence of contact information and formal business details suggests it is maintained by volunteers or a small group rather than a formal company. The long domain age supports its credibility within the community. There are no visible revenue streams or strategic partnerships. Growth potential may be limited without modernization and enhanced user engagement features.

Security posture

The security posture of lua-users.org is weak. The absence of HTTPS is a critical issue, exposing users to potential data interception risks. No security headers are detected, and there is no evidence of security policies or incident response mechanisms. The lack of privacy and cookie policies indicates non-compliance with GDPR and other privacy regulations. No vulnerability disclosure or security.txt files are present. The site does not collect user data via forms, which reduces some risk but also limits user interaction. Overall, the site is vulnerable to common web threats and lacks a security culture or framework.

Recommendations

  1. Enable HTTPS with a valid SSL/TLS certificate to secure user connections.
  2. Implement standard security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Publish privacy and cookie policies to improve transparency and compliance with GDPR.
  4. Add clear contact information and a security incident response contact to enhance trust and readiness.
  5. Consider adding a vulnerability disclosure policy or security.txt file to encourage responsible reporting.

Technical notes

Notes

The website uses basic HTML and CSS without modern JavaScript frameworks or CMS platforms. Hosting is provided by pair Networks, a known registrar and hosting provider. The site performance is likely moderate given the simple content and lack of heavy resources. Mobile optimization and accessibility are basic, with no explicit features detected. SEO optimization is minimal, with only basic meta tags present. There is no evidence of analytics or tracking technologies, indicating minimal data collection. The technical debt is low but modernization opportunities exist to improve security, performance, and user experience.
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.
