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

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"

      • OWASP A04:2025
      • ASVS V3.4.1
    • High

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

Hanse Haus operates in the real estate sector focusing on prefabricated homes, targeting families and investors in Germany and Switzerland. Their competitive advantages include a long history, multiple awards for fair pricing, and sustainability certifications. The business model combines product sales with consulting and planning services. The company leverages digital tools like virtual 360° tours and online configurators to enhance customer engagement. Partnerships include regional sites such as hanse-haus.ch for the Swiss market. The company demonstrates a mature digital presence and a strong brand reputation.

Security posture

The website enforces HTTPS and uses a reputable consent management platform (Usercentrics) to handle cookie policies, indicating good privacy compliance. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. However, the absence of explicit security headers and a public security policy or incident response contact reduces the overall security maturity. The site uses secure form frameworks and avoids common pitfalls. Recommendations include adding security headers and publishing a vulnerability disclosure policy to enhance trust and security readiness.

Recommendations

  1. Add and enforce security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  2. Publish a clear privacy policy and terms of service pages accessible from the homepage.
  3. Implement and publicize a vulnerability disclosure or security.txt file to facilitate responsible reporting.
  4. Provide explicit contact information for data protection officer or security incident response.
  5. Regularly audit third-party scripts and tracking tools to minimize privacy risks and improve compliance.

Technical notes

Notes

The website is built on TYPO3 CMS, a robust and widely used content management system, ensuring scalability and maintainability. It uses modern HTML5 features such as responsive images and video embedding for rich media content. The site integrates Usercentrics for GDPR-compliant cookie consent and Google Tag Manager for analytics. Performance is moderate with good mobile optimization and accessibility features. The technical stack is modern but could benefit from enhanced security headers and performance optimizations. Hosting details are not explicitly found but DNS name servers indicate professional DNS 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.
