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

End of 10 is a non-profit campaign focused on encouraging users to transition from Windows 10 to Linux as Windows 10 support ends in 2025. The campaign promotes digital sustainability by extending the life of existing hardware, improving privacy, and reducing environmental impact. It leverages community support and partnerships with various open source and digital rights organizations to provide assistance and resources for Linux installation and computer repair. Technically, the website is built using the Hugo static site generator, with good performance and mobile optimization. However, it lacks explicit privacy and cookie policies, security headers, and incident response information, which are areas for improvement. The domain registration uses privacy protection, which is common for advocacy sites, but the WHOIS data shows an inconsistent creation date, possibly a data error. Overall, the site is trustworthy and serves a niche community with a clear mission but should enhance its privacy and security posture to improve compliance 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. 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 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

The campaign targets Windows 10 users with older hardware, environmentally conscious individuals, and open source communities. Its business model is non-profit and advocacy-based, relying on community engagement and partnerships with recognized organizations in the open source and digital rights space. The website features a network of supporters and repair collectives, indicating a collaborative ecosystem. The campaign's market position is niche but important in the context of digital sustainability and software freedom. Revenue streams are likely donation-based or volunteer-supported. Growth indicators include expanding language support and community events. Strategic observations suggest focusing on enhancing privacy compliance and security transparency to strengthen credibility.

Security posture

The website uses HTTPS and includes Subresource Integrity for CSS assets, indicating attention to content integrity. However, it lacks visible security headers such as Content-Security-Policy, X-Frame-Options, and others that enhance protection against common web attacks. No vulnerability disclosure or incident response policies are published, and no security contact emails are provided. The domain uses privacy protection, which is acceptable but reduces transparency. No analytics or tracking scripts were detected, minimizing privacy risks. Overall, the security maturity is moderate but can be improved by implementing security headers, publishing security policies, and enabling DNSSEC.

Recommendations

  1. Implement and publish a comprehensive privacy policy and cookie consent mechanism to improve GDPR compliance.
  2. Add security headers like Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance security posture.
  3. Publish a vulnerability disclosure policy and security.txt file to facilitate responsible reporting and incident response.
  4. Enable DNSSEC on the domain to improve DNS security and trustworthiness.
  5. Provide clear contact information including security and incident response contacts to enhance transparency and trust.

Technical notes

Notes

The website is built with Hugo, a modern static site generator, ensuring fast loading times and good performance. CSS assets use Subresource Integrity and crossorigin attributes, indicating security awareness. The site is mobile optimized and accessible with good SEO metadata including Open Graph tags and JSON-LD structured data. Hosting details are not explicit but DNS is managed via cloudns.net and domain registrar is NameCheap. No client-side analytics or tracking scripts were detected, reducing privacy concerns. The technical stack is modern and well implemented but could benefit from enhanced security configurations and explicit hosting information.
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.
