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

Datatilsynet is the central independent Danish authority responsible for supervising compliance with data protection regulations, including GDPR. The organization provides guidance, handles complaints, and conducts oversight of public authorities and businesses. Positioned as a government regulatory body, Datatilsynet serves a broad audience including companies, citizens, and youth, emphasizing responsible data use in a digital society. The website reflects a professional and authoritative presence with comprehensive content tailored to various stakeholders. Technically, the site is built on a custom ASP.NET platform with jQuery and modern web standards, delivering good performance and accessibility. Security posture is solid with HTTPS usage and no visible vulnerabilities, though security headers and explicit incident response policies could be improved. Overall, the site demonstrates strong business credibility and compliance focus, with minor gaps in cookie consent mechanisms and vulnerability disclosure. The WHOIS data is unavailable, likely due to privacy protection common in .dk domains, but the domain and content strongly indicate legitimacy. Strategic recommendations include enhancing security headers, publishing security policies, and implementing cookie consent to further strengthen compliance and trust.

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: 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 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

Datatilsynet operates as a government regulatory authority in Denmark, focusing on data protection and GDPR enforcement. Its market position is authoritative and central within the Danish public sector. The business model revolves around regulatory oversight, public guidance, and complaint resolution rather than commercial revenue. The target customers include businesses processing personal data, citizens seeking information on their rights, and educational institutions. The organization maintains partnerships with national and international data protection bodies, as evidenced by linked domains like whistleblower.dk. Growth indicators include active publication of news, guidance, and thematic content on emerging technologies such as AI and cloud computing. The website's professional design and comprehensive content support its role as a trusted public institution.

Security posture

The website demonstrates a mature security posture with enforced HTTPS and no visible exposure of sensitive data or vulnerable libraries. However, the absence of security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options suggests room for improvement. No explicit incident response or security policy documentation is found, and no vulnerability disclosure or security.txt file is published. The site does not appear to use tracking or advertising scripts, reducing privacy risks. Overall, the security posture is good but could be enhanced by adopting additional HTTP security headers, publishing clear security policies, and implementing a vulnerability disclosure program to improve transparency and incident readiness.

Recommendations

  1. Implement comprehensive HTTP security headers including CSP, HSTS, and X-Frame-Options.
  2. Add a cookie consent mechanism to comply fully with GDPR requirements.
  3. Publish a detailed security policy and incident response plan accessible on the website.
  4. Establish and publicize a vulnerability disclosure program or security.txt file.
  5. Regularly audit third-party scripts and dependencies to ensure no vulnerabilities are introduced.

Technical notes

Notes

The website is built on a custom ASP.NET Web Forms platform using jQuery and modern CSS techniques. It employs a proprietary CMS framework (GoBasic) for content management. The site is mobile responsive and accessible, with good SEO practices including meta tags and Open Graph data. Performance is moderate, with no major issues detected. The absence of common analytics or tracking scripts suggests a privacy-focused approach. Technical risks include potential outdated dependencies and lack of advanced security headers. Opportunities exist to modernize the tech stack and enhance security configurations to align with best practices for government websites.
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.
