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. 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

  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
    • High

      SSL Certificate Expires Soon

      SSL certificate expires in 29 days

      What to do: Renew SSL certificate before expiration

      • NIS2 21(2)(h)
      • IR 2024/2690 9.2(c): Implementing Regulation (EU) 2024/2690, Annex point 9.2(c): Cryptography

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 operates in the energy sector focusing on geothermal solutions and district heating, a niche with growing importance in sustainable energy markets. Their business model revolves around utility services with bundled internet offerings, targeting local customers. The website content and structure suggest a medium-sized enterprise with consistent branding and a clear service portfolio. The absence of explicit contact emails or phone numbers on the homepage indicates a controlled customer interaction approach, likely via dedicated portals and service pages. The use of Matomo analytics and cookie consent reflects awareness of privacy regulations. No partnerships or subsidiaries are explicitly mentioned, indicating a focused operational scope.

Security posture

The website enforces HTTPS and uses cookie consent banners, indicating baseline security and privacy compliance. However, the lack of security headers such as Content-Security-Policy or X-Frame-Options reduces defense-in-depth. No incident response or vulnerability disclosure information is published, which could hinder transparency and trust in security matters. No vulnerabilities or exposed sensitive data were detected in the HTML content. The use of WordPress and plugins requires regular updates to mitigate risks. Overall, the security posture is moderate with room for improvement in headers and policy transparency.

Recommendations

  1. Implement and configure security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to enhance protection against common web attacks.
  2. Publish a clear security policy and incident response contact information to improve transparency and customer trust.
  3. Regularly audit and update WordPress core and plugins to minimize vulnerability exposure.
  4. Consider adding a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  5. Enhance accessibility features and SEO optimization to improve user experience and search engine visibility.

Technical notes

Notes

The website is built on WordPress 6.8.3 with jQuery and Bootstrap frameworks, supported by custom plugins for block management and cookie consent. The site loads moderate resources and is mobile optimized with responsive design. SEO is basic with proper meta tags but could be improved with structured data. No hosting provider details were found, but DNS name servers indicate German hosting consistent with the business location. Performance is moderate with no critical errors detected. The technical stack is modern but could benefit from enhanced 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.
