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

The OpenJS Foundation, operated under The Linux Foundation, serves as a central hub for the collaborative development and widespread adoption of JavaScript and web technologies globally. It supports numerous key open source JavaScript projects, provides community collaboration spaces, and offers training and events to foster growth and innovation in the JavaScript ecosystem. The foundation enjoys strong backing from major technology companies, reflecting its significant market position in the open source and developer communities. Technically, the website is built on a modern stack including React and Next.js, hosted on Vercel, and managed with Prismic CMS. It demonstrates excellent performance, mobile optimization, and accessibility features, indicating a mature digital infrastructure. The site integrates analytics tools such as Google Analytics and Google Tag Manager for user insights while maintaining a professional and user-friendly design. From a security perspective, the site enforces HTTPS and maintains domain transfer protections, though it lacks DNSSEC and some advanced security headers. The presence of a dedicated security page and comprehensive legal policies reflects a commitment to security and compliance, although explicit incident response contacts and vulnerability disclosure mechanisms are absent. Privacy compliance is generally good, with clear privacy and cookie policies, but the lack of a cookie consent mechanism is a minor gap. Overall, the OpenJS Foundation website presents a high level of professionalism, trustworthiness, and technical maturity. It effectively supports its mission to promote JavaScript technologies while maintaining a secure and compliant online presence. Strategic improvements in DNS security and privacy consent mechanisms would further enhance its security posture and compliance standing.

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 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 Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  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 Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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.

Business context

Business profile

The OpenJS Foundation operates as a non-profit entity under The Linux Foundation, focusing on the JavaScript technology sector. It leverages a membership-based business model, engaging major industry players such as Google, IBM, Meta, and Microsoft. The foundation's revenue streams likely include membership fees, training programs, and event sponsorships. Its target customers are developers, enterprises, and open source communities invested in JavaScript technologies. The foundation's competitive advantage lies in its central role in uniting diverse JavaScript projects and fostering collaboration. Growth indicators include active project hosting, community engagement, and regular events like JSConf.

Operationally, the foundation maintains a strong digital presence with modern infrastructure and comprehensive governance.

Security posture

The OpenJS Foundation exhibits a mature security posture with enforced HTTPS, domain transfer protections, and a dedicated security information page. However, the absence of DNSSEC and certain security headers such as Content Security Policy and HSTS represents areas for improvement. No vulnerabilities or exposed sensitive data were detected in the website content. The lack of explicit incident response contacts and a security.txt file limits transparency in vulnerability management. Privacy policies are comprehensive and GDPR compliant, but cookie consent mechanisms are not implemented, which could pose compliance risks. Overall, the foundation demonstrates good security hygiene but should address these gaps to enhance resilience and compliance.

Recommendations

  1. Enable DNSSEC on the domain to strengthen DNS security and prevent spoofing.
  2. Implement security headers including Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options to mitigate common web vulnerabilities.
  3. Publish a security.txt file and provide explicit incident response contact information to improve vulnerability disclosure and response processes.
  4. Introduce a cookie consent banner or mechanism to comply fully with GDPR and other privacy regulations.
  5. Regularly audit third-party scripts and analytics tools to minimize privacy risks and ensure compliance.

Technical notes

Notes

The website is built using a modern React and Next.js framework, leveraging server-side rendering and static site generation for performance optimization. It uses Prismic as a headless CMS, enabling flexible content management. Hosting is provided by Vercel, known for fast global CDN delivery and scalability. The site includes Google Analytics and Google Tag Manager for tracking, integrated asynchronously to minimize performance impact. Mobile responsiveness and accessibility are well implemented, with semantic HTML and ARIA roles evident. The site uses optimized images with srcset for responsive loading. No technical debt or deprecated technologies were detected. Opportunities exist to enhance security headers and DNS configurations to further reduce risk.
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.
