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

10 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 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';…

  3. 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

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

MapLibre operates in the technology sector with a focus on geospatial and mapping software. Its competitive advantage lies in GPU-accelerated rendering, multi-platform support, and active open-source community engagement. The organization leverages GitHub for code hosting and collaboration and maintains a presence on multiple social media platforms to engage with its user base. The project is relatively young, founded in 2020, and backed by the Open Source Collective, which provides legitimacy and governance. Revenue streams are likely indirect, through sponsorships, donations, and community support rather than direct sales.

Security posture

The website benefits from HTTPS and Cloudflare hosting, providing a solid baseline for transport security. However, it lacks explicit security headers and published security policies such as incident response or vulnerability disclosure. No forms or data collection mechanisms are present, reducing attack surface. The absence of DNSSEC is a minor security gap. Overall, the security posture is moderate but could be improved by publishing security policies, enabling DNSSEC, and adding security headers.

Recommendations

  1. Publish a comprehensive privacy policy and cookie policy to improve compliance and user trust.
  2. Implement and publish a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  3. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  4. Add standard security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  5. Provide clear incident response contact information to improve transparency and readiness.

Technical notes

Notes

The website uses a modern tech stack including Astro framework, TypeScript, Rust, and C++ for its projects. It is hosted on Cloudflare, ensuring good performance and security. The site is mobile-optimized and uses Bootstrap for responsive design. Preloading of fonts and map tiles indicates performance optimization. No CMS detected, indicating a custom or static site generation approach. The technical implementation is robust with good SEO and accessibility considerations, though some security best practices could be enhanced.
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.
