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

Stadtwerke Bonn operates as a regional public utility company in Germany, providing energy and transportation services. Their website, swb-karriere.de, serves as a comprehensive career portal targeting students, apprentices, professionals, and job seekers interested in joining the company. The portal offers detailed information on job openings, training programs, and employee testimonials, positioning the company as an attractive employer in the regional market. Technically, the website is built on TYPO3 CMS, leveraging modern JavaScript libraries and a cookie consent framework to ensure GDPR compliance. The site is mobile-optimized, accessible, and professionally designed, reflecting a mature digital presence. Security-wise, the site enforces HTTPS and employs cookie consent mechanisms, though it lacks explicit security headers and a public security policy or incident response contact. Overall, the website demonstrates a strong security posture with room for improvement in transparency and security best practices. The domain registration data aligns well with the company's business claims, supporting legitimacy and trustworthiness. Strategic recommendations include enhancing security headers, publishing a security policy, and providing clear incident response contacts 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 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 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 Bonn holds a solid market position as a regional energy and transportation provider with a focus on sustainable and community-oriented services. Their career portal reflects a strategic emphasis on talent acquisition and workforce development, targeting multiple audience segments including apprentices, students, and experienced professionals. The company leverages certifications and memberships such as BMBF, Open Company, Top Company, and Charta der Vielfalt to reinforce employer branding and social responsibility. The business model centers on public utility services combined with a strong internal culture and employee development programs. The website's integration with social media platforms and multimedia content supports engagement and brand visibility. No direct revenue streams from the website are evident, indicating its primary role as a recruitment and informational platform. The company appears to maintain a medium to large organizational size with a professional digital infrastructure.

Security posture

The website exhibits a good security posture with mandatory HTTPS encryption and a GDPR-compliant cookie consent mechanism that defaults to denying tracking until user consent is given. No sensitive data or credentials are exposed in the HTML content. The use of Google Tag Manager and Google Analytics is controlled via consent, minimizing privacy risks. However, the absence of explicit security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options represents an area for improvement. There is no visible security policy or incident response contact information, which could hinder timely vulnerability reporting and incident management. No known vulnerabilities or suspicious scripts were detected. Overall, the site is secure but could benefit from enhanced security transparency and header implementation.

Recommendations

  1. Implement and enforce security headers including CSP, HSTS, and X-Frame-Options to mitigate common web vulnerabilities.
  2. Publish a dedicated security policy page outlining security practices and compliance measures.
  3. Provide clear contact information for security incidents, including dedicated email addresses such as security@ or abuse@ domains.
  4. Introduce a security.txt file to facilitate responsible vulnerability disclosure.
  5. Regularly audit third-party scripts and dependencies to ensure no vulnerable libraries are included.

Technical notes

Notes

The website is powered by TYPO3 CMS, a robust and widely used open-source content management system, indicating a mature technical foundation. The frontend uses modern JavaScript libraries such as Owl Carousel for interactive sliders and Biscuit for cookie consent management. Google Tag Manager is integrated for analytics and marketing tag management, with Google Analytics disabled by default pending user consent, reflecting privacy-conscious implementation. The site is hosted on infrastructure associated with netcologne.de, a German hosting provider, supporting regional compliance and performance. The website is mobile-optimized and accessible, with good SEO practices including meta tags and structured data (JSON-LD). Performance is moderate, with potential for optimization in loading times and resource management. No critical technical debt or deprecated technologies were identified.
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.
