Risk levelMedium

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

Stadtwerke Sonneberg GmbH operates as a municipal service provider in Sonneberg, Germany, focusing on culture, sports, and tourism services such as Sonnebad, Gesellschaftshaus, and tourism information. The website is built on the Wix platform, indicating a moderate level of digital maturity with standard Wix hosting and JavaScript technologies. While the site includes basic content and some operational monitoring via Sentry, it lacks critical privacy and cookie policies, as well as explicit contact information, which impacts its privacy compliance and user trust. Security posture is moderate with HTTPS implied but missing explicit security headers and incident response contacts. Overall, the website serves its informational purpose but requires improvements in privacy, security, and contact transparency to enhance 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

6 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 Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

  2. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  3. 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';…

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

The company is positioned as a local municipal service provider with a focus on energy-related services and community amenities in tourism and culture. Its business model revolves around providing public services to residents and visitors. The website's use of Wix suggests a cost-effective digital presence suitable for small to medium-sized enterprises. There is no evidence of extensive marketing, affiliate programs, or advanced analytics, indicating a straightforward service approach. The lack of detailed business data such as founding year or subsidiaries limits deeper business intelligence insights.

Security posture

The website demonstrates a basic security posture with HTTPS usage and integration of Sentry for error monitoring. However, the absence of security headers like Content-Security-Policy and lack of published security policies or incident response contacts indicate gaps in security best practices. No vulnerabilities or exposed sensitive data were detected in the provided content. The site would benefit from enhanced security configurations and transparency to meet modern compliance standards such as GDPR and NIS2.

Recommendations

  1. Publish a comprehensive privacy policy and cookie policy with GDPR compliance details.
  2. Implement security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Provide clear contact information including emails and phone numbers for general and security-related inquiries.
  4. Regularly audit and update third-party scripts to mitigate potential vulnerabilities.
  5. Enhance website accessibility and SEO metadata to improve user experience and search visibility.

Technical notes

Notes

The website is hosted on Wix, utilizing Wix's proprietary CMS and JavaScript libraries, including polyfills for browser compatibility and Sentry for error tracking. The site shows moderate performance and good mobile optimization typical of Wix sites. However, there is limited evidence of advanced frameworks or custom backend technologies. The technical implementation is standard for small business websites but could be improved with better SEO, accessibility, and security configurations.
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.
