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

Semantic MediaWiki is an established open-source software extension to MediaWiki that enables semantic data storage and querying within wiki pages, transforming wikis into powerful knowledge management systems. The project is supported by an active community and sponsorships, positioning it as a niche leader in semantic wiki technology. The website is professionally designed, well-structured, and provides comprehensive resources for users, developers, and administrators. Technically, it leverages MediaWiki 1.31.16, jQuery, Bootstrap, and Semantic Result Formats, indicating a mature but somewhat dated technology stack. Security posture is moderate with HTTPS usage implied but lacking explicit security headers and cookie consent mechanisms. WHOIS data is unavailable, likely due to privacy protection, but the website's legitimacy is supported by its community presence and sponsorships. Overall, the site is trustworthy and serves its target audience effectively.

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

6 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

    • High

      No SPF record found

      SPF helps prevent email spoofing

      What to do: Add SPF record: "v=spf1 include:_spf.yourmailprovider.com ~all"

  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 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

    • 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

Semantic MediaWiki operates as a small, community-driven open-source project focused on semantic wiki technology. Its business model relies on sponsorships and consulting services rather than direct sales. The target audience includes developers, knowledge managers, and organizations seeking semantic wiki solutions. The project maintains partnerships with several specialist companies providing consulting and customization services. The website's content and structure reflect a mature project with a clear focus on knowledge management and semantic web integration. Growth indicators include recent software releases and active community engagement. The ecosystem includes GitHub, social media, and mailing lists, supporting collaboration and support.

Security posture

The website demonstrates a moderate security maturity level. HTTPS is used, ensuring encrypted communications. However, the absence of security headers such as Content Security Policy, HSTS, and X-Frame-Options reduces protection against common web attacks. No incident response or vulnerability disclosure policies are published, limiting transparency in security management. No analytics or tracking scripts were detected, reducing privacy risks. The lack of cookie consent mechanisms may pose compliance challenges under GDPR. Overall, the site is secure for general use but could improve by implementing recommended security headers and publishing clear security policies.

Recommendations

  1. Implement comprehensive security headers including CSP, HSTS, and X-Frame-Options to enhance protection.
  2. Add a cookie consent banner and cookie policy to improve privacy compliance.
  3. Publish a clear security policy and vulnerability disclosure process to increase transparency and trust.
  4. Regularly update MediaWiki and extensions to the latest stable versions to mitigate vulnerabilities.
  5. Consider publishing contact information for security incidents and appointing a Data Protection Officer if applicable.

Technical notes

Notes

The website is built on MediaWiki 1.31.16 with Semantic MediaWiki and related extensions, using jQuery and Bootstrap for frontend components. The HTML is valid and well-structured, supporting good SEO and accessibility. Performance is moderate, with no heavy scripts detected in the provided HTML. Mobile optimization is good, with responsive design elements. The site lacks advanced analytics or tracking, indicating a privacy-conscious approach. Hosting provider details are not discernible from the HTML. Technical debt may exist due to the use of an older MediaWiki version, suggesting opportunities for modernization and security improvements.
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.
