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

The Open Source Initiative (OSI) is a well-established global non-profit organization dedicated to advocating, educating, and stewarding the Open Source software ecosystem. Founded in 1998, OSI plays a critical role in defining and maintaining the Open Source Definition and approving licenses, positioning itself as a trusted authority in the open source community. The website reflects a mature digital presence with professional design, clear navigation, and a focus on community engagement through programs, events, and partnerships. Technically, the site is built on WordPress with modern plugins and libraries, hosted behind Cloudflare DNS and CDN services, ensuring good performance and security. Security posture is solid with HTTPS enforced and clientTransferProhibited domain status, though DNSSEC is not enabled and explicit security policies are not published. Privacy compliance is partially addressed with a cookie consent mechanism but lacks a clearly accessible privacy policy or terms of service. Overall, OSI demonstrates high business credibility and trustworthiness, supported by consistent WHOIS data and a long domain history.

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

5 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"

    • 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 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

  4. DNS health

    DNS sends visitors and email to the right servers. Misconfigured records can cause outages or let someone redirect your traffic.

    • High

      Weak SPF Policy

      SPF record has permissive policy allowing any server to send email

      What to do: Use -all or ~all qualifier for better email security

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

OSI operates as a non-profit entity focused on the technology sector, specifically open source software advocacy and licensing. Its business model revolves around community membership, educational programs, events, and ecosystem support rather than commercial sales. The organization targets developers, companies, and open source communities worldwide, with over 5000 active members and representation in 100+ countries. OSI's market position is strong as a steward of open source licensing standards, supported by partnerships with major industry players and endorsements from recognized leaders. The website content and testimonials reinforce OSI's role as a thought leader and trusted authority. The presence of partner domains like members.opensource.org and endof10.org indicates a collaborative ecosystem. Revenue streams likely include memberships, donations, and sponsorships.

Security posture

The website enforces HTTPS and uses Cloudflare DNS, providing a secure transport layer and DNS infrastructure. The domain status clientTransferProhibited prevents unauthorized transfers, enhancing domain security. However, DNSSEC is not enabled, which could improve DNS integrity. No explicit security policy, incident response, or vulnerability disclosure pages were found, indicating room for improvement in transparency and readiness. The cookie consent mechanism complies with GDPR requirements to some extent, but the absence of a privacy policy page is a compliance gap. No vulnerabilities or exposed sensitive data were detected in the HTML content. Security headers are likely present but not explicitly confirmed. Overall, the security posture is good but could be enhanced by publishing security policies, enabling DNSSEC, and adding vulnerability disclosure mechanisms.

Recommendations

  1. Enable DNSSEC on the domain to strengthen DNS security and prevent spoofing.
  2. Publish a comprehensive privacy policy and terms of service pages accessible from the homepage.
  3. Create and publish a security policy and incident response page to improve transparency and readiness.
  4. Implement a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  5. Review and ensure all recommended security headers (CSP, X-Content-Type-Options, X-Frame-Options) are properly configured.

Technical notes

Notes

The website is built on a modern WordPress CMS platform using Gutenberg blocks, jQuery, and Swiper.js for interactive elements. It leverages Cloudflare for DNS and CDN services, enhancing performance and security. The site uses the Complianz GDPR plugin for cookie consent management and Jetpack for additional functionality. Performance is moderate with good mobile optimization and accessibility features. SEO is well addressed with proper meta tags and Open Graph data. The site design is professional and consistent with the organization's branding. Technical risks are minimal, but enabling DNSSEC and improving security headers would further reduce risk. The site does not expose sensitive data and uses secure forms where applicable.
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.
