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

5 findings rated critical or high. Fix these first.

  1. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • 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 Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

    • High

      Third-party services without privacy policy

      Detected services: Facebook, LinkedIn

      What to do: Document all third-party data sharing in your privacy policy

  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 SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

SMHI holds a strong market position as Sweden's official meteorological authority, providing essential weather and climate services. Its competitive advantage lies in government backing, authoritative data, and comprehensive service offerings including forecasts, warnings, and research publications. The target customers range from the general public to specialized professionals and researchers. The website reflects a mature digital presence with integration of analytics and consent management tools. Partnerships with video platforms like YouTube and Vimeo are used for embedded content. Growth indicators include continuous content updates and professional services. The ecosystem is primarily government and public sector focused, with no evident commercial partnerships or subsidiaries.

Security posture

The website exhibits a mature security posture with HTTPS enforced and standard security headers likely in place. The use of nonce attributes in scripts and a robust cookie consent mechanism indicate attention to security and privacy. However, the absence of a published security policy, incident response contacts, or vulnerability disclosure mechanisms suggests room for improvement in transparency and incident readiness. No vulnerabilities or exposed sensitive data were detected in the analyzed content. Compliance with GDPR is evident through privacy and cookie policies. The site would benefit from publishing explicit security documentation and incident response procedures to enhance trust and preparedness.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and commitments.
  2. Provide clear incident response contact information, such as a security or abuse email address.
  3. Implement and publish a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Review and enhance Content-Security-Policy headers to mitigate script injection risks.
  5. Regularly audit third-party scripts and dependencies to ensure no vulnerable libraries are in use.

Technical notes

Notes

The website is built on the SiteVision CMS platform and uses React 17.0.2 for frontend components. It integrates Matomo analytics for user tracking and CookieYes for cookie consent management. The site loads multiple CSS and JavaScript resources asynchronously, indicating a modern approach to performance optimization. Mobile responsiveness and accessibility features are well implemented, including ARIA attributes and assistive text. The site uses nonce attributes in inline scripts to enhance security. Performance is moderate, with potential for further optimization. No hosting provider details were found in the provided data. Overall, the technical infrastructure supports a professional and user-friendly experience with scope for incremental improvements in security headers and performance tuning.
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.
