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

The Linux Foundation is a prominent non-profit organization dedicated to supporting and protecting the Linux trademark and fostering open source technology projects. Their website provides comprehensive information about the Linux trademark sublicensing program, legal guidelines, and contact channels for trademark queries and abuse reporting. The organization targets technology companies, developers, and the broader Linux user community, positioning itself as a trusted authority in open source governance and trademark management. Technically, the website is built on the HubSpot CMS platform, utilizing modern web technologies such as jQuery, Font Awesome, and Google Tag Manager. The site is mobile-optimized, accessible, and well-structured, reflecting a mature digital presence. Security measures include HTTPS enforcement and privacy consent mechanisms, although explicit security headers could be more visible. From a security perspective, the site demonstrates good practices with secure forms, privacy compliance, and no visible vulnerabilities. However, the absence of WHOIS data limits the ability to fully verify domain registration legitimacy, which slightly impacts trust assessment. Overall, the site is professional, secure, and compliant with privacy regulations, serving its audience effectively. The risk assessment is low given the organization's reputation and website quality, but improving transparency on domain registration and enhancing security headers would strengthen trust further. Strategic recommendations include implementing explicit security headers, maintaining up-to-date WHOIS information, and expanding incident response disclosures.

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

3 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"

  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

  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.

    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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 Linux Foundation operates as a leading non-profit in the open source ecosystem, managing trademarks and providing infrastructure for open source projects. Its business model revolves around trademark licensing, education, events, and research, targeting technology companies and developers globally. The foundation's competitive advantage lies in its authoritative control over the Linux trademark and its extensive ecosystem of projects and partners. Revenue streams likely include sponsorships, training, and event fees. The organization maintains a strong partnership network and a consistent brand presence, reinforcing its market leadership and trustworthiness.

Security posture

The website exhibits a mature security posture with enforced HTTPS, secure form handling, and privacy consent mechanisms. No critical vulnerabilities or exposed sensitive data were detected. However, the lack of explicit security headers such as Content-Security-Policy and X-Frame-Options suggests room for improvement. Incident response contact is available via trademark abuse reporting emails, but a formal security policy or vulnerability disclosure program is not evident. Compliance with GDPR is indicated through privacy policies and cookie consent. Overall, the security maturity is good but could benefit from enhanced header policies and clearer incident response documentation.

Recommendations

  1. Implement and explicitly declare security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Ensure WHOIS domain registration data is complete and publicly accessible to improve transparency and trustworthiness.
  3. Develop and publish a formal security policy and vulnerability disclosure program to improve incident response readiness and community trust.
  4. Maintain and regularly update privacy and cookie policies to stay compliant with evolving regulations such as GDPR and CCPA.
  5. Enhance monitoring of third-party scripts and tracking tools to minimize potential security risks and improve user privacy.

Technical notes

Notes

The website is built on the HubSpot CMS platform, leveraging modern web technologies including jQuery and Font Awesome for UI components, and Google Tag Manager for analytics and marketing integration. The site is mobile responsive with good accessibility features and SEO optimization. Performance is moderate, with deferred loading of scripts and use of CDN-hosted libraries. The technical infrastructure is robust for a content-driven site, though explicit hosting provider details are not disclosed. Opportunities exist to optimize security headers and streamline third-party script usage to reduce attack surface and improve load times.
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.
