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.

Priority findings

4 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 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 cooperative holds a strong market position as Duisburg's largest housing cooperative, targeting local residents and prospective tenants. Its business model focuses on cooperative housing rental and member services, with a clear emphasis on community and tenant support. The website's detailed navigation and content structure indicate a mature digital presence, supporting tenant applications, contact, and information dissemination. The presence of social media links and downloadable resources suggests active engagement and transparency. No parent or subsidiary companies are indicated, highlighting an independent cooperative structure. The cooperative's longevity and comprehensive service offerings position it well within the regional real estate sector.

Security posture

The website demonstrates a moderate to strong security posture with HTTPS enforced and a cookie consent mechanism aligned with GDPR. No security headers were explicitly detected in the HTML content, and no incident response or security policy pages were found, indicating room for improvement in transparency and formal security governance. No vulnerabilities or exposed sensitive data were observed. The use of modern CMS and scripts without known vulnerabilities supports a secure environment. Recommendations include publishing a security policy, adding security headers, and providing incident response contacts to enhance trust and compliance.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and controls.
  2. Provide clear incident response contact information for reporting security issues.
  3. Implement HTTP security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  4. Regularly review and update third-party scripts and libraries to mitigate vulnerabilities.
  5. Enhance transparency by detailing data retention policies and security certifications if applicable.

Technical notes

Notes

The website is powered by TYPO3 CMS, leveraging Bootstrap for responsive design and jQuery-based plugins for enhanced user interaction such as date pickers and form handling. The site loads compressed CSS and JS assets, indicating optimization efforts. The presence of a cookie consent modal and integration with Google Analytics shows compliance with privacy regulations and analytics usage. Performance is moderate with good mobile optimization and accessibility features. No hosting provider details were found in the HTML or WHOIS data, but the domain uses multiple German nameservers. The technical stack is modern and well-maintained, supporting a positive user experience and operational stability.
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.
