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

Freifunk.net is a well-established community-driven platform dedicated to promoting free and open communication networks in digital data networks. Founded in 2003, it operates as a decentralized non-commercial initiative primarily targeting technology enthusiasts and local community groups in Germany. The website offers a variety of services including community news aggregation, mailing lists, collaborative tools, and event calendars, supporting the growth and maintenance of free wireless mesh networks. The platform maintains a consistent brand presence and provides multilingual support with a focus on German and English audiences. Technically, the website is built on WordPress 6.8.1 with a robust set of plugins for SEO, GDPR compliance, event management, and multilingual content. It employs Matomo analytics, emphasizing privacy-conscious data collection. The site is mobile-optimized with good navigation and accessibility features, although some accessibility aspects could be enhanced. Hosting details are partially known, with domain registration through INWX GmbH and no DNSSEC enabled, representing a minor security gap. From a security perspective, the site enforces HTTPS and uses domain transfer protection, but lacks advanced security headers and published security policies. No vulnerabilities or exposed sensitive data were detected in the content. Privacy compliance is strong with a clear privacy policy and cookie consent mechanism. However, incident response and vulnerability disclosure policies are not publicly available, which could be improved to enhance trust and readiness. Overall, Freifunk.net presents a trustworthy, professional, and community-focused platform with a solid technical foundation and good privacy practices. Strategic improvements in DNS security, security policy transparency, and accessibility would further strengthen its security posture and user trust.

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

4 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 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

Freifunk.net occupies a unique niche as a decentralized community network initiative in Germany, leveraging grassroots participation to build free wireless infrastructure. Its competitive advantage lies in its open, non-commercial model and strong community engagement through multiple communication channels and collaborative tools. The business model is based on volunteer contributions and donations, with no direct revenue streams evident. The target audience includes local communities, technology hobbyists, and advocates for open networks. Growth indicators include active event promotion, frequent community news updates, and multilingual content. The ecosystem includes partnerships with local Freifunk communities and integration with social media platforms. Operationally, the platform demonstrates maturity with a stable domain history and consistent branding, though it could benefit from enhanced formalization of security and compliance processes.

Security posture

The security maturity of Freifunk.net is moderate to good. The site enforces HTTPS and uses domain transfer lock to prevent unauthorized changes. However, the absence of DNSSEC and security headers such as Content Security Policy or HSTS reduces its defense-in-depth. No direct contact channels for security incidents or vulnerability disclosures are published, which limits incident response readiness. The use of Matomo analytics reflects a privacy-conscious approach, aligning with GDPR compliance. No exposed credentials or sensitive data were found, and the WordPress installation appears up-to-date. To elevate security posture, the organization should implement DNSSEC, publish a security policy, and establish clear incident response contacts. Overall, the platform shows a positive security culture but with room for improvement in formal security governance.

Recommendations

  1. Enable DNSSEC on the freifunk.net domain to enhance DNS security and prevent spoofing.
  2. Implement and configure security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), X-Frame-Options, and X-Content-Type-Options.
  3. Publish a dedicated security policy page including incident response procedures and security contact information (e.g., security@freifunk.net or abuse@freifunk.net).
  4. Establish a vulnerability disclosure program and consider adding a security.txt file at the root domain.
  5. Improve website accessibility features to meet higher standards and enhance user experience for all visitors.

Technical notes

Notes

The website is powered by WordPress 6.8.1 with a comprehensive set of plugins supporting SEO (Yoast), GDPR compliance, event aggregation, multilingual content (WPML), and community collaboration tools. The tech stack includes jQuery, Bootstrap, and Podlove Web Player for multimedia content. Hosting details are not fully disclosed but domain registration is stable with INWX GmbH. Performance is moderate with good mobile optimization and SEO meta tags properly configured. The site uses Matomo analytics, which is privacy-focused and self-hosted. There is no evidence of outdated or vulnerable libraries in the HTML content. The site could benefit from modern security enhancements and improved accessibility compliance to reduce technical debt and improve resilience.
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.
