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

8 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.

Add-on

Leaked records that mention openmaptiles.org, from OffSeq Breach.

No leaked records found

Breach holds no records for openmaptiles.org right now. New leaks arrive continuously, so monitoring on Breach alerts you if that changes.

Technical appendix

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

Business context

Business profile

The business model combines open-source software distribution with commercial cloud-based map hosting and data services. This hybrid approach leverages community contributions and broad adoption while generating revenue from hosting and API usage. The company benefits from strong brand recognition and trust signals, including endorsements from major technology firms and an active GitHub presence. The partnership with MapTiler enhances their market reach and service offerings. Growth potential lies in expanding cloud services and catering to enterprise GIS needs.

Security posture

The website employs HTTPS and Cloudflare DNS services, providing a solid baseline for transport security. However, DNSSEC is not enabled, which could improve DNS integrity. No explicit security policies, incident response contacts, or vulnerability disclosure mechanisms are published, indicating room for maturity in security governance. The absence of privacy and cookie policies suggests compliance gaps with GDPR and related regulations. Tracking via Google Tag Manager is present without visible consent mechanisms, which may pose privacy risks. Overall, the security posture is moderate but would benefit from enhanced transparency and policy publication.

Recommendations

  1. Enable DNSSEC to strengthen DNS security and prevent spoofing.
  2. Publish comprehensive privacy and cookie policies to improve GDPR compliance and user trust.
  3. Implement a cookie consent mechanism to comply with privacy regulations.
  4. Provide clear contact information for security incidents and vulnerability reporting.
  5. Add security headers such as Content-Security-Policy and X-Frame-Options to harden the website.

Technical notes

Notes

The website uses modern JavaScript technologies and integrates Google Tag Manager for analytics. It is hosted behind Cloudflare, ensuring good performance and availability. The site is mobile-optimized with responsive design and clear navigation. However, no CMS or major frameworks are detected, indicating a custom or lightweight implementation. SEO is supported by proper meta tags and Open Graph data. Accessibility is basic but could be improved with additional ARIA attributes and semantic markup. Overall, the technical infrastructure is solid but could benefit from enhanced security headers and privacy controls.
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.
