Risk levelMedium

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

Stockholm International Water Institute (SIWI) is a well-established non-profit organization focused on water governance and sustainable water management. Founded in 1997, SIWI operates globally to influence policy and decision-making in water-related sustainable development. The website reflects a professional and consistent brand presence targeting policymakers, researchers, and water sector professionals. Technically, the site is built on WordPress with modern frameworks like Bootstrap and hosted on Microsoft Azure DNS infrastructure, indicating a moderate to good level of digital maturity. Security posture is adequate with HTTPS and domain transfer protections, but lacks DNSSEC and explicit security policies. Privacy compliance is weak due to missing privacy and cookie policies. Overall, the site is trustworthy and content-rich but would benefit from enhanced privacy and security 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

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 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 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. 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
    • High

      Weak SSL Key Length

      SSL certificate uses 384-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

SIWI holds a strong market position as a global leader in water policy research and advocacy. Its business model is non-profit, focusing on knowledge dissemination, capacity building, and hosting flagship events like World Water Week. The organization targets international stakeholders including governments, NGOs, and research institutions. The website's content and structure support these objectives, though there is room for improvement in transparency around privacy and security. Partnerships and social media presence are evident, enhancing its ecosystem and outreach. The domain age and registration details align well with the organization's history, reinforcing credibility.

Security posture

The website demonstrates a baseline security posture with HTTPS and domain status protections. However, the absence of DNSSEC, security.txt, vulnerability disclosure, and incident response contacts indicates gaps in security maturity. No explicit security headers beyond standard HTTPS were confirmed. The lack of privacy and cookie policies also suggests compliance risks, especially under GDPR. No WAF or blocking mechanisms were detected, allowing full content access. Recommendations include enabling DNSSEC, publishing security policies, and improving header configurations to enhance defense-in-depth and compliance.

Recommendations

  1. Enable DNSSEC on the domain to protect against DNS spoofing and improve trust.
  2. Publish a comprehensive privacy policy and cookie consent mechanism to comply with GDPR and enhance user trust.
  3. Implement and link to a security.txt file and vulnerability disclosure policy to facilitate responsible security reporting.
  4. Add or strengthen HTTP security headers such as Content-Security-Policy and X-Frame-Options.
  5. Provide clear incident response contact information to improve transparency and readiness.

Technical notes

Notes

The website uses WordPress CMS with Bootstrap for responsive design, Select2 for enhanced form controls, and Swiper.js for interactive elements. Hosting on Azure DNS suggests reliable infrastructure. Performance is moderate with good mobile optimization and basic accessibility features. SEO optimization is basic with standard meta tags but no advanced structured data or rich snippets detected. The site lacks advanced analytics or tracking scripts, indicating minimal user tracking. Technical debt appears low but could be improved by adopting DNSSEC and enhancing security headers.
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.
