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

DMI is the Danish Meteorological Institute, a government agency providing comprehensive weather forecasts, climate data, and research services primarily for Denmark, Greenland, and the Faroe Islands. The website offers local weather forecasts, radar and satellite imagery, weather warnings, and climate-related information targeting the general public, researchers, and government entities. The business model is focused on public service and scientific data dissemination, positioning DMI as the authoritative national meteorological institute. Technically, the website is built on TYPO3 CMS with modern JavaScript frameworks such as React and jQuery, and uses Highcharts for data visualization. The site is well-optimized for mobile devices and accessibility, with good SEO practices and a moderate performance profile. The cookie consent mechanism is robust and GDPR compliant, reflecting a mature digital infrastructure. From a security perspective, the site enforces HTTPS and employs a detailed cookie consent banner with categorized cookies and third-party data processors. However, security headers are not explicitly detected in the provided data, and no vulnerability disclosure or security policy pages were found. There are no signs of blocking or WAF interference, and no exposed sensitive data was observed. Overall, the website is professional, trustworthy, and compliant with privacy regulations, though the absence of WHOIS data limits domain registration trust analysis. Strategic recommendations include enhancing security headers, publishing a security.txt file, and maintaining regular audits of third-party scripts to ensure ongoing security and compliance.

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

2 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

  2. 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

DMI holds a strong market position as Denmark's official meteorological institute, serving a broad audience including citizens, researchers, and governmental bodies. Its competitive advantage lies in authoritative data, comprehensive weather services, and free access to climate data. The business model is public service-oriented, funded by government resources, focusing on data accuracy and accessibility rather than commercial revenue. The website integrates with multiple third-party analytics and advertising platforms, indicating a balanced approach to user experience and operational funding. Growth indicators include active research publications and engagement with educational initiatives. The partnership ecosystem includes data processors like Microsoft, Adform, and Gemius, supporting technical and marketing functions. Strategic observations highlight the importance of maintaining data integrity and privacy compliance to uphold public trust.

Security posture

The security maturity level of the website is moderate to good. HTTPS is enforced, and a detailed cookie consent mechanism supports GDPR compliance. The site uses third-party analytics and advertising services with transparent disclosures. However, the absence of explicit security headers such as Content-Security-Policy and X-Frame-Options suggests room for improvement. No vulnerabilities or exposed sensitive data were detected in the HTML content. The lack of a published security policy or incident response contact reduces transparency in security governance. Compliance with GDPR is evident, but additional NIS2 or ISO 27001 framework references are not found. Incident response readiness and security culture indicators are not explicitly documented. Overall, the site demonstrates a responsible security posture suitable for a government entity but could enhance defenses and transparency.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web attacks.
  2. Publish a security policy and a security.txt file to provide clear vulnerability disclosure and incident response information.
  3. Regularly audit and update third-party scripts and libraries to prevent vulnerabilities from dependencies.
  4. Enhance transparency by providing explicit information about data protection officers and incident response contacts.
  5. Maintain and improve cookie consent mechanisms to ensure ongoing compliance with evolving privacy regulations.

Technical notes

Notes

The website is built on TYPO3 CMS, leveraging React and jQuery for dynamic content and user interface components. Highcharts is used for interactive data visualization, and proj4.js supports geospatial mapping features. The site includes a detailed cookie consent banner powered by Cookie Information, indicating a mature approach to privacy compliance. Performance is moderate, with deferred loading of JavaScript bundles and optimized CSS. Mobile optimization and accessibility features are well implemented, including ARIA roles and keyboard navigation support. SEO is supported by meta tags and Open Graph properties. Technical risks include reliance on multiple third-party analytics and advertising services, which require ongoing monitoring for privacy and security compliance. Hosting provider details are not explicitly identified in the content.
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.
