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

SIDN fonds is a Dutch non-profit organization dedicated to supporting innovative internet projects that contribute to a safer and more inclusive internet. With over 400 projects funded since 2015, it holds a strong position within the Dutch internet community, focusing on themes such as cybersecurity, digital accessibility, and public values. The website provides comprehensive information about its mission, funding opportunities, and supported projects, targeting innovators and organizations involved in internet initiatives. Technically, the website is hosted on Google Cloud infrastructure using OpenResty as the web server. It employs a robust Content Security Policy and integrates multiple analytics and marketing tools including Piwik PRO and Google Analytics. The site is mobile-optimized with good accessibility and SEO practices. However, a critical security gap is the absence of a valid SSL/TLS certificate, resulting in no HTTPS support, which significantly impacts the security posture. Security-wise, while several security headers are implemented, the lack of HTTPS and disabled TLS protocols expose the site to risks such as data interception and man-in-the-middle attacks. No explicit security or incident response policies are published, and no vulnerability disclosure mechanisms are evident. Privacy and cookie policies are present and appear comprehensive, supporting GDPR compliance. Overall, the site is professionally designed and content-rich but requires urgent improvements in SSL/TLS deployment to enhance security and trustworthiness. Strategic recommendations include obtaining a valid SSL certificate, enabling modern TLS protocols, and enhancing security headers to protect users and data effectively.

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, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

SIDN fonds operates as a specialized funding entity within the technology and non-profit sectors, focusing on internet-related projects with societal impact. Its business model revolves around grant-making and thematic calls to stimulate innovation in internet safety, digital skills, and public values. The organization leverages partnerships within the Dutch internet ecosystem and maintains a visible presence through its website and social media channels. The fund's competitive advantage lies in its established reputation and targeted support for pioneering projects. Growth indicators include active themacalls and a growing portfolio of supported initiatives. The website content and structure reflect a mature digital presence aimed at transparency and community engagement.

Security posture

The current security posture of the SIDN fonds website is moderate but with critical deficiencies. The presence of a strong Content Security Policy and multiple security headers indicates awareness of web security best practices. However, the absence of a valid SSL certificate and disabled TLS protocols represent significant vulnerabilities, exposing users to potential data interception and undermining trust. The disabled X-XSS-Protection header further weakens defenses against cross-site scripting attacks. No published security policy or incident response information limits transparency and preparedness. The site does not provide a vulnerability disclosure policy or security.txt file, which are recommended for responsible security management. Overall, the site requires immediate remediation of SSL/TLS issues and enhancement of security governance documentation.

Recommendations

  1. Obtain and deploy a valid SSL/TLS certificate to enable HTTPS across the entire site.
  2. Enable and configure modern TLS protocols (TLS 1.2 and TLS 1.3) to secure data in transit.
  3. Review and enable the X-XSS-Protection header or rely on CSP to mitigate cross-site scripting risks.
  4. Publish a clear security policy and incident response plan accessible to users and partners.
  5. Implement a vulnerability disclosure policy and consider adding a security.txt file for transparency.

Technical notes

Notes

The website is served by OpenResty on Google Cloud infrastructure, indicating a modern and scalable hosting environment. The tech stack includes JavaScript with inline and external scripts, SVG graphics for logos and icons, and integration with analytics platforms such as Piwik PRO and Google Analytics. The site uses a comprehensive Content Security Policy to restrict resource loading to trusted domains. Performance data is unavailable, but the site appears optimized for mobile devices and accessibility. No CMS is explicitly detected. The DNS setup uses SIDN name servers with no DNSSEC enabled. The SSL configuration is currently non-existent, which is a critical technical gap. Overall, the infrastructure is modern but requires SSL/TLS implementation to meet current security standards.
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.
