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

Stadtwerke Bochum is a well-established regional energy provider based in Bochum, Germany, with a history spanning approximately 170 years. The company offers a broad range of energy-related services including electricity (with green energy options), natural gas, district heating, water supply, solar energy solutions, heat pumps, and e-mobility services. Their target audience includes both private and business customers within the Bochum region. The website reflects a mature digital presence with comprehensive service information, customer support channels, and active social media engagement. Technically, the website is built on TYPO3 CMS and leverages modern web technologies such as jQuery, Bootstrap, and various UI libraries. It employs a consent management platform (Usercentrics) and integrates Google Tag Manager for analytics, indicating a focus on privacy compliance and user experience. The site is mobile-optimized and accessible, with good SEO practices. From a security perspective, the site uses HTTPS with good SSL configuration and incorporates consent-based script loading. It holds ISO 27001 certification and displays multiple trust badges, reinforcing its commitment to security and sustainability. No critical vulnerabilities or exposed sensitive data were detected.

Overall, Stadtwerke Bochum's website demonstrates a strong security posture, excellent content quality, and robust privacy compliance. It serves as a trustworthy digital front for a major regional utility provider. Strategic recommendations include enhancing security header implementation, publishing incident response information, and maintaining regular audits of third-party scripts.

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 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

  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

Stadtwerke Bochum holds a strong market position as a regional energy supplier with a diversified portfolio including electricity, gas, heating, water, and e-mobility. Their business model focuses on providing essential utility services to residential and commercial customers, supported by digital tools such as an online customer center and mobile apps. The company leverages partnerships with local government (e.g., Bochum city) and maintains certifications that enhance credibility. Growth indicators include new dynamic tariffs and sustainability initiatives. The company’s ecosystem includes bonus programs and customer engagement through apps and social media, reflecting a customer-centric approach.

Security posture

The website exhibits a mature security posture with HTTPS enforced, ISO 27001 certification, and use of a consent management platform. Security best practices such as consent-based loading of tracking scripts and absence of exposed sensitive data are evident. However, some security headers are not explicitly visible in the HTML, and no public incident response or vulnerability disclosure policy is found. The lack of a security.txt file is a minor gap. Overall, the site is secure for its business context but could improve transparency and header configurations.

Recommendations

  1. Explicitly implement and verify security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  2. Publish an incident response or abuse contact page to improve transparency and readiness.
  3. Add a security.txt file to facilitate vulnerability reporting.
  4. Regularly audit third-party scripts and dependencies for vulnerabilities.
  5. Maintain and update privacy and cookie policies in line with evolving regulations.

The site uses Usercentrics for GDPR-compliant consent management and Google Tag Manager for analytics. Hosting is managed via tmr.net nameservers, indicating professional hosting infrastructure. Performance is moderate with good mobile optimization and accessibility features. The site is SEO-optimized with proper meta tags and structured data (JSON-LD). Opportunities exist to enhance security headers and streamline third-party script management.
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.
