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

deck.gl is an open source GPU-powered data visualization framework designed for large-scale data analysis and rendering. It is supported by the OpenJS Foundation and targets developers and data scientists who require high-performance visualization tools integrated with popular mapping platforms. The website reflects a mature project with a consistent brand and professional content focused on technical users. The technical infrastructure is modern, leveraging JavaScript, WebGL2, WebGPU, and React, and is built on the Docusaurus CMS framework, ensuring good performance, accessibility, and SEO. Security posture is adequate with HTTPS and domain transfer protection, but lacks DNSSEC and security headers. Privacy and compliance documentation are missing, which reduces trust and compliance scores. Overall, the site is trustworthy and professional 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

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 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 Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • 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

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

deck.gl occupies a strong niche in the technology sector as a specialized visualization framework. Its open source business model is supported by the OpenJS Foundation, indicating community and industry backing. The project benefits from integration with major base map providers, enhancing its utility and market reach. The absence of direct contact information and privacy policies suggests a focus on developer communities rather than direct commercial sales. The presence of a Slack workspace, GitHub repository, and blog indicates active community engagement and content marketing. The domain age and registration details align well with the project's timeline, supporting legitimacy. There are no indications of advertising or tracking, emphasizing a developer-centric approach.

Security posture

The website enforces HTTPS and has domain transfer protections, which are positive security indicators. However, the lack of DNSSEC and absence of common security headers such as Content-Security-Policy and X-Frame-Options represent areas for improvement. No explicit security policies, incident response contacts, or vulnerability disclosure mechanisms are published, which could hinder rapid response to security issues. No vulnerabilities or exposed sensitive data were detected in the analysis. The overall security maturity is moderate, suitable for an open source project but with room for enhancement to meet enterprise-grade standards.

Recommendations

  1. Publish a comprehensive privacy policy and cookie policy to improve compliance and user trust.
  2. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  3. Implement standard security headers (Content-Security-Policy, X-Frame-Options, etc.) to mitigate common web attacks.
  4. Provide explicit contact information for security incidents and consider publishing a vulnerability disclosure policy or security.txt file.
  5. Enhance transparency around data collection and tracking practices, even if minimal, to align with GDPR and other privacy regulations.

Technical notes

Notes

The website uses a modern technology stack including JavaScript, WebGL2, WebGPU, and React, supported by the Docusaurus CMS framework. The site is well-structured with proper meta tags for SEO and social sharing (Open Graph, Twitter cards). Performance is optimized with deferred script loading and prefetching of assets. Mobile optimization and accessibility features are good, ensuring a broad user reach. Hosting provider details are not explicit but the domain is registered with a reputable registrar. No technical debt or deprecated technologies were detected. The site lacks some security best practices such as DNSSEC and security headers, which should be addressed to reduce risk.
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.
