The website reflects a mature digital presence with professional design, clear navigation, and comprehensive service information. Technically, the site uses modern frameworks like React and integrates consent management and analytics tools, indicating a good level of digital maturity.

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. 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 Policy found

      GDPR requires clear information about cookie usage

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

    • 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

HanseWerk AG holds a strong position in the northern German energy market, leveraging diversified energy solutions and telecommunications services. Its business model centers on utility services, infrastructure management, and technical support, targeting residential, commercial, and municipal customers. The company’s ecosystem includes several subsidiaries, enhancing its market reach and service capabilities. The website’s integration with partner domains related to grid management and APIs suggests a well-connected operational infrastructure. Growth indicators include focus on renewable energy, electric mobility, and digital services. The company maintains a professional online presence with clear contact channels and compliance with privacy regulations, supporting customer trust and regulatory adherence.

Security posture

The website demonstrates a good security posture with HTTPS enforced and use of security headers such as CSP. Consent management is implemented via Usercentrics, supporting GDPR compliance. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of published security policies, incident response plans, and vulnerability disclosure mechanisms represents a compliance gap and potential risk area. The lack of a security.txt file limits external vulnerability reporting. Recommendations include publishing explicit security and incident response policies, implementing a vulnerability disclosure program, and enhancing security headers for defense in depth. Overall, the security maturity is moderate to good but can be improved to meet best practices and regulatory expectations.

Recommendations

  1. Publish a dedicated security policy and incident response information on the website.
  2. Implement and publicize a vulnerability disclosure policy and security.txt file.
  3. Enhance HTTP security headers with additional directives such as X-Frame-Options and X-XSS-Protection.
  4. Regularly audit and update third-party scripts and libraries to mitigate vulnerabilities.
  5. Maintain transparency on data retention policies and improve user privacy controls.

Technical notes

Notes

The website is built on a modern technology stack including React and Adobe Experience Manager CMS, with integration of Usercentrics for consent management and Matomo and Google Tag Manager for analytics. The site is mobile optimized with good accessibility and SEO practices. Performance is moderate, with asynchronous loading of scripts and use of CDN-hosted resources. The technical infrastructure supports a professional user experience and compliance with privacy regulations. Opportunities exist to optimize performance further and enhance security configurations. The integration with partner domains indicates a complex backend ecosystem supporting energy grid and customer management services.
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.
