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

The Open Source Security Foundation (OpenSSF) is a Linux Foundation-hosted initiative focused on enhancing the security of open source software. It operates as a non-profit collaborative foundation, targeting open source developers, security professionals, and organizations relying on open source components. The foundation provides security best practices, tooling, community collaboration, and educational resources to improve open source security posture globally. The website reflects a professional and consistent brand aligned with its mission and parent organization, the Linux Foundation. Technically, the website is built on WordPress, leveraging modern web technologies and integrations with marketing and analytics platforms such as HubSpot and Google Analytics. The site is hosted with reputable providers and uses HTTPS, ensuring secure communications. Mobile optimization and SEO practices are adequately implemented, though accessibility features are basic. From a security perspective, the site enforces HTTPS and has domain transfer protections in place. However, DNSSEC is not enabled, and no explicit security headers or vulnerability disclosure policies are present. Privacy and cookie policies are not clearly linked, though a cookie consent mechanism is active via HubSpot scripts. No contact emails or phone numbers are directly found in the provided content, which limits direct communication channels. Overall, the website demonstrates a solid business credibility and technical foundation with room for improvement in privacy compliance and security best practices. Strategic enhancements in DNS security, policy transparency, and incident response readiness would further strengthen trust and security posture.

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.

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

Business profile

OpenSSF occupies a strategic position in the open source security ecosystem, leveraging the Linux Foundation's reputation and resources. Its collaborative model fosters partnerships across the technology sector, focusing on improving security standards and tooling for open source projects. Revenue streams are likely based on foundation memberships, sponsorships, and grants rather than commercial sales. The target audience includes developers, enterprises, and security teams invested in open source software integrity. The foundation's growth is supported by increasing industry focus on supply chain security and open source risk management. Partnerships with major technology companies and community engagement are key competitive advantages.

Security posture

The website's security posture is moderate. HTTPS is enforced, and domain transfer protections are active, reducing risks of domain hijacking. However, the absence of DNSSEC leaves DNS queries vulnerable to spoofing attacks. No security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), or X-Frame-Options were detected, which are recommended to mitigate common web attacks. The lack of a published vulnerability disclosure policy or security.txt file limits transparency and incident response readiness. Privacy policy and cookie disclosures are minimal, which may impact GDPR compliance. Overall, the site is secure for general use but would benefit from enhanced DNS security, security headers, and formalized incident response documentation.

Recommendations

  1. Enable DNSSEC to protect DNS integrity and prevent spoofing.
  2. Implement and configure security headers including CSP, HSTS, and X-Frame-Options.
  3. Publish a comprehensive privacy policy and cookie policy accessible from the website footer.
  4. Create and publish a vulnerability disclosure policy and security.txt file to improve transparency and incident response.
  5. Add explicit contact information for security incidents such as security@ or abuse@ email addresses.

Technical notes

Notes

The website is built on WordPress CMS with a modern theme and uses several plugins including Events Calendar Pro and HubSpot integrations. It employs external resources such as FontAwesome for icons and Google Fonts for typography. Analytics and marketing tools include Google Analytics, Google Tag Manager, HubSpot Ads Pixel, and LinkedIn Insight Tag, indicating a mature digital marketing setup. The site is hosted with DNS managed by DNSimple and domain registered via 1API GmbH. Performance is moderate with good mobile optimization. Accessibility features are basic and could be improved. The technical stack is stable but could benefit from enhanced security configurations and updated privacy compliance mechanisms.
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.
