OpenMapTiles is an open-source mapping project operated by MapTiler AG, providing vector tiles and map hosting solutions primarily for developers and GIS professionals seeking self-hosted map infrastructure. The website demonstrates a solid market position with trusted partnerships and a strong community presence on GitHub. Technically, the site uses modern JavaScript libraries and Google Tag Manager for analytics, with good mobile optimization and SEO practices, though some accessibility features could be improved. Security posture is moderate with HTTPS implied but lacking explicit security headers and published policies. Privacy compliance is weak due to absence of privacy and cookie policies or consent mechanisms. Overall, the site is professional and trustworthy but would benefit from enhanced transparency and security documentation.

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.
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
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"
This scan found 26 issues across 6 checks. Monitoring re-runs those checks daily, emails you when something material changes and records each fix, so you can show progress.

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.

Breach holds no records for openmaptiles.org right now. New leaks arrive continuously, so monitoring on Breach alerts you if that changes.
Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.
Business context
Business profile
The business operates in the technology sector focusing on open-source geospatial data and map hosting services. Its competitive advantage lies in providing free vector tile schemas and maps with the option for paid hosting, appealing to developers and organizations needing customizable map solutions. The company leverages partnerships and community contributions to maintain and grow its offerings. Revenue likely derives from hosting services and enterprise support. The ecosystem includes major technology companies as clients or collaborators, enhancing credibility and market reach.
Security posture
The website shows a moderate security maturity level with HTTPS usage but lacks visible security headers and published security or incident response policies. No vulnerabilities or exposed sensitive data were detected in the HTML content. The absence of a vulnerability disclosure or security.txt file limits transparency for security researchers. Privacy compliance gaps exist, particularly regarding GDPR-related disclosures and cookie consent. Incident response readiness is unclear due to missing contact channels for security issues. Overall, the security posture is adequate but could be significantly improved with formal policies and headers.
Recommendations
Publish a comprehensive privacy policy and cookie policy with GDPR compliance details.
Implement and serve security headers such as Content-Security-Policy, Strict-Transport-Security, X-Frame-Options, and X-Content-Type-Options.
Add a vulnerability disclosure policy and security.txt file to facilitate responsible reporting.
Provide clear contact information including security incident response contacts.
Enhance accessibility features to improve inclusivity and compliance with standards.

Technical notes
Notes
The website uses a modern JavaScript-based front-end with asynchronous loading of Google Tag Manager scripts and integration with open-source mapping libraries. The HTML structure is valid and includes appropriate meta tags for SEO and social media sharing. Performance is moderate with room for optimization. Mobile responsiveness is good, and navigation is clear. However, no CMS or hosting provider details are evident. The site could benefit from improved accessibility and security header implementation to reduce technical risks.
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.
