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

The Sustainable Development Solutions Network (SDSN) is a globally recognized non-profit organization operating under the auspices of the United Nations Secretary-General. It mobilizes a vast network of over 2,000 universities, think tanks, and research institutions worldwide to promote and implement solutions aligned with the Sustainable Development Goals (SDGs) and the Paris Agreement. The organization focuses on education, research, policy analysis, and fostering global cooperation to address critical sustainable development challenges. Its market position is strong, supported by a large membership base and clear UN affiliation. Technically, the SDSN website is built using modern technologies such as Astro and is hosted on Cloudflare Pages, ensuring fast performance and excellent mobile optimization. The site employs Google Tag Manager and Google Analytics for tracking and marketing purposes, reflecting a mature digital infrastructure. The website is well-designed, accessible, and SEO optimized, providing a professional user experience. From a security perspective, the site enforces HTTPS, uses multiple security headers, and shows no signs of vulnerabilities or exposed sensitive data. However, it lacks a visible cookie consent mechanism and dedicated security or incident response policies, which are areas for improvement. The WHOIS data is unavailable due to privacy protection, which is justified given the organization's nature. Overall, the security posture is strong but could benefit from enhanced privacy compliance features. The overall risk assessment is low, with the website demonstrating high professionalism, trustworthiness, and compliance with best practices. Strategic recommendations include implementing cookie consent, publishing security policies, and adding vulnerability disclosure information to further enhance trust and compliance.

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

6 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • 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 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

  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

SDSN operates as a non-profit knowledge network with a clear focus on sustainable development and global cooperation. Its competitive advantage lies in its UN affiliation and extensive global network of academic and research institutions. The business model centers on collaboration, education, and policy advocacy rather than commercial revenue generation. Target customers include universities, policymakers, and development practitioners. Growth indicators include expanding membership and active engagement in global forums such as the UN High-Level Political Forum. The partnership ecosystem includes academic institutions and UN bodies. The organization's operations reflect a mature and well-established presence in the sustainable development sector.

Security posture

The SDSN website demonstrates a mature security posture with enforced HTTPS, comprehensive security headers, and no visible vulnerabilities or sensitive data exposure. However, the absence of a cookie consent mechanism and published security or incident response policies indicates gaps in privacy compliance and transparency. There is no evidence of a dedicated data protection officer contact or vulnerability disclosure program, which are recommended for organizations handling global stakeholder engagement. Overall, the security culture appears strong but could be enhanced by formalizing privacy and incident response communications.

Recommendations

  1. Implement a clear and user-friendly cookie consent banner to comply with privacy regulations.
  2. Publish a dedicated security policy and incident response plan accessible to users.
  3. Add a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Provide contact information for a Data Protection Officer or privacy contact to enhance GDPR compliance.
  5. Maintain transparency in WHOIS data or provide justification for privacy protection to improve trust.

Technical notes

Notes

The website leverages Astro framework version 5.5.6, indicating a modern static site generation approach. Hosting on Cloudflare Pages provides robust CDN and security features, contributing to fast load times and global availability. The use of Google Tag Manager and Google Analytics reflects advanced marketing and analytics capabilities. The site is mobile-optimized with responsive design and accessibility features, supporting a broad user base. No CMS is explicitly detected, suggesting a custom or static site approach. The technical infrastructure is modern, performant, and well-maintained, with opportunities to enhance privacy compliance and security transparency.
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.
