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

Sønderborg Kommune operates an official municipal website providing comprehensive information on culture, jobs, newcomer services, youth programs, and business opportunities within the Sonderborg region of Denmark. The website serves as a key digital portal for residents and visitors, positioning itself as a trusted source of local government information and community engagement. The business model is focused on public service and community support, with a medium-sized organizational footprint consistent with municipal operations. Technically, the website is built on WordPress using the Divi theme, integrating modern web technologies such as jQuery, Matomo analytics for privacy-conscious tracking, and Cookiebot for cookie consent management. The site demonstrates good SEO practices and mobile optimization, though accessibility features are basic. Performance is moderate, with room for optimization. From a security perspective, the site enforces HTTPS and uses cookie consent mechanisms, but lacks advanced security headers and published security policies or incident response information. No vulnerabilities or exposed sensitive data were detected in the analyzed content. The domain registration is consistent and longstanding, reinforcing trustworthiness. Overall, the website presents a professional and credible digital presence for the municipality, with recommendations to enhance security posture by enabling DNSSEC, adding security headers, and publishing security and vulnerability disclosure policies to further strengthen trust 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

3 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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • 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. 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

Sønderborg Kommune's website reflects a well-established local government entity focused on serving the community with cultural, employment, and newcomer information. The site targets residents, newcomers, youths, and local businesses, providing essential municipal services and information. The business model is non-commercial, centered on public service delivery. The website's market position is that of an authoritative government portal, supported by consistent branding and official contact details. The presence of a Facebook group indicates community engagement and social media integration. The lack of commercial advertising or affiliate programs aligns with its government nature. Growth indicators include active event calendars and job listings, supporting community development.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforced and cookie consent implemented via Cookiebot. However, it lacks several security best practices such as DNSSEC, security headers (CSP, HSTS, X-Frame-Options), and published security or incident response policies. No vulnerabilities or exposed sensitive data were found in the HTML content. The absence of a vulnerability disclosure policy or security.txt file suggests limited formal security communication channels. Overall, the security posture is adequate for a government informational site but could be improved to meet higher standards of security and compliance.

Recommendations

  1. Enable DNSSEC to protect against DNS spoofing and improve domain security.
  2. Implement security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options to enhance protection against common web attacks.
  3. Publish a clear security policy and incident response plan on the website to improve transparency and preparedness.
  4. Add a vulnerability disclosure policy or security.txt file to facilitate responsible reporting of security issues.
  5. Conduct regular security audits and update third-party libraries and plugins to mitigate potential vulnerabilities.

Technical notes

Notes

The website is built on a mature WordPress CMS platform using the Divi theme, supported by jQuery and integrated with Matomo analytics and Cookiebot for privacy compliance. The technical infrastructure is standard for government websites, offering good SEO and mobile responsiveness. Performance is moderate, with potential for optimization in loading speed and accessibility enhancements. The use of structured data (JSON-LD) improves search engine understanding and visibility. No hosting provider details were explicitly detected. The site uses external resources from trusted domains such as YouTube and Google Fonts. Overall, the technical implementation is solid but could benefit from modern security enhancements 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.
