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

4 findings rated critical or high. Fix these first.

  1. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  2. 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';…

  3. 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

  4. 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.

Technical appendix

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

Business context

Business profile

The Open Visualization Collaboration Space operates as a governance and community platform under the OpenJS Foundation, focusing on open source visualization libraries for geospatial and big data applications. Its business model revolves around open source collaboration, industry engagement, and community-driven development rather than direct revenue generation. The project benefits from partnerships with major technology organizations such as Google, IBM, and Facebook, enhancing its market position. The target audience includes developers, data scientists, and organizations interested in advanced web visualization technologies. The presence of regular summits, community meetings, and active GitHub repositories indicates a healthy ecosystem and growth potential. The foundation affiliation adds credibility and stability to the initiative.

Security posture

The website exhibits a mature security posture with enforced HTTPS, comprehensive security headers, and no exposed sensitive information. However, it lacks explicit security policies, vulnerability disclosure programs, and incident response contact details, which are important for transparency and rapid response to security incidents. The absence of a security.txt file or dedicated security page is a gap. Privacy policies and cookie policies are well documented and linked to foundation-wide resources, supporting GDPR compliance. No signs of malware, phishing, or other malicious activity were detected. The site’s security practices align well with industry standards for open source foundation projects but could be improved by adding dedicated security governance documentation.

Recommendations

  1. Implement a dedicated security policy page including incident response contacts and procedures.
  2. Publish a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  3. Add a cookie consent mechanism to enhance GDPR compliance and user transparency.
  4. Provide clear contact information for security and privacy inquiries on the website.
  5. Regularly review and update third-party dependencies and scripts to mitigate potential vulnerabilities.

Technical notes

Notes

The website is built using a modern tech stack including React and Next.js frameworks, leveraging server-side rendering and static site generation for performance. It uses Prismic as a headless CMS for content management and is hosted on Vercel, ensuring fast global delivery. The site integrates advanced web technologies such as WebGL and WebGPU for visualization capabilities. Performance is optimized with lazy loading of images and scripts, and mobile responsiveness is excellent. Accessibility features are implemented to a good standard. SEO is well addressed with comprehensive meta tags and Open Graph data. The technical infrastructure is robust, scalable, and aligned with best practices for modern web applications.
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.
