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

The ClusterDuck Protocol is an open-source initiative focused on empowering communities through resilient wireless IoT networks using LoRa technology. It primarily targets emergency communication and sensor networks, enabling civilians and responders to maintain connectivity during disasters. The project is community-driven, with resources and code hosted on GitHub and active engagement via Discord and Medium blogs. The website presents a professional and well-structured interface with good mobile optimization, though it lacks explicit privacy and cookie policies. Technically, it uses modern web standards and integrates Google Analytics for user tracking. Security posture is moderate, with HTTPS implied but lacking DNSSEC and security headers. The domain registration is transparent and consistent with the project's timeline, 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

9 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

  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 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

    • 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

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

ClusterDuck Protocol occupies a niche in the IoT and disaster relief market, leveraging open-source development to foster innovation and community participation. Its business model is non-commercial, focusing on technology enablement and community support rather than direct revenue. The project benefits from partnerships and mentions in reputable technology and disaster relief publications, enhancing its credibility. Target customers include developers, emergency responders, and communities seeking robust communication solutions. Growth potential lies in expanding hardware compatibility and increasing adoption in disaster-prone regions. The absence of formal business contact information and policies suggests a primarily volunteer-driven or non-profit orientation.

Security posture

The website demonstrates a basic security maturity level with HTTPS usage and domain transfer protection. However, it lacks DNSSEC, security headers, and published security policies or incident response contacts. No vulnerability disclosure or security.txt files are present, limiting transparency for security researchers. The use of Google Analytics without visible cookie consent may raise privacy compliance concerns under GDPR. No exposed sensitive data or vulnerable libraries were detected in the provided content. Overall, the security posture is adequate for an informational open-source project but would benefit from enhanced security controls and compliance documentation.

Recommendations

  1. Enable DNSSEC to strengthen DNS security and prevent spoofing.
  2. Implement and publish comprehensive privacy and cookie policies with consent mechanisms.
  3. Add security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  4. Provide a vulnerability disclosure policy and security.txt file to facilitate responsible reporting.
  5. Include clear contact information for business and security incident response to improve trust and compliance.

Technical notes

Notes

The website uses standard HTML5, CSS3, and JavaScript technologies with integration of Google Fonts and Google Analytics. The site is mobile-optimized and features a clean, modern design. Hosting and domain registration are managed by reputable providers. Performance is moderate, with no major issues detected in the content. The absence of a CMS suggests a custom or static site approach. Technical debt appears low, but the lack of advanced security configurations and privacy compliance features indicates areas for modernization. Overall, the technical infrastructure supports the project's goals but could be enhanced with improved security and compliance features.
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.
