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

Nemhandel.dk is a Danish government-operated platform managed by Erhvervsstyrelsen (Danish Business Authority) that facilitates electronic invoicing and e-commerce document exchange primarily for public sector entities and businesses in Denmark. The platform enjoys a strong market position with over 67,000 registered recipients and processes over 31 million e-commerce documents annually, reflecting high adoption and trust within its target audience. The website is well-branded, consistent, and professionally designed, supporting a good user experience and accessibility. Technically, the site is built on Drupal CMS with modern web technologies, offering good mobile optimization and SEO practices. Security posture is solid with HTTPS enforced and cookie consent mechanisms implemented, although some security headers and DNSSEC are missing. Privacy compliance is strong, with clear privacy and cookie policies aligned with GDPR requirements. No critical vulnerabilities or blocking mechanisms were detected, and the domain registration is consistent with the official government entity, enhancing legitimacy 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

4 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 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 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

  3. 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

Nemhandel.dk operates as an essential government service platform within the Danish public sector, providing critical infrastructure for e-invoicing and digital business transactions. Its competitive advantage lies in its official status and integration with public sector invoicing requirements, ensuring near-universal adoption for public invoices. The business model is service-oriented, focusing on enabling digital commerce rather than direct revenue generation. The platform targets businesses and public institutions in Denmark, supported by partnerships with other government digital initiatives. Growth indicators include a large volume of transactions and registered users. The ecosystem includes related government digital services, enhancing its strategic position in Denmark's digital transformation efforts.

Security posture

The website demonstrates a mature security posture with mandatory HTTPS, cookie consent, and privacy-conscious analytics via Piwik Pro. However, the absence of DNSSEC and security headers such as Content-Security-Policy and X-Frame-Options represents areas for improvement. No incident response or security policy information is published, which could hinder transparency and preparedness. No vulnerabilities or exposed sensitive data were detected in the analysis. Overall, the security posture is strong for a government service but could benefit from enhanced DNS security and published security policies.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS integrity and prevent spoofing.
  2. Implement and publish security headers like Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Publish a dedicated security policy and incident response contact information to improve transparency and readiness.
  4. Consider adding a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  5. Regularly review and update cookie and privacy policies to maintain GDPR compliance and user trust.

Technical notes

Notes

The website is built on Drupal CMS with a modern front-end stack including JavaScript and CSS3, using SVG for graphics. The site is mobile-optimized and accessible, with good SEO meta tags and structured navigation. Performance is moderate, with no major issues detected. The use of Piwik Pro analytics indicates a privacy-focused approach to user tracking. Hosting provider details are not explicitly identified. The site could improve by enabling DNSSEC and adding security headers. Overall, the technical infrastructure is solid and supports the business goals effectively.
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.
