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

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

    • 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

  2. Security headers

    • High

      Missing Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

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 company operates in the Real Estate sector focusing on landscape architecture services. Their business model is service-oriented, providing design, planning, consulting, and project management. The firm targets a diverse client base including investors, urban planners, and private clients. Their market position is that of an established medium-sized firm with a creative and international team. The website's social media presence on Facebook and Xing supports their professional network and client engagement. No direct revenue streams or parent/subsidiary relationships are evident from the data. The company appears to maintain a strong brand consistency and trust through professional content and clear contact information.

Security posture

The website demonstrates a moderate security posture with HTTPS enforced and email address obfuscation to reduce spam. However, it lacks important security headers such as Content-Security-Policy and X-Frame-Options, which could improve protection against common web attacks. There is no visible security policy or incident response contact information, which limits transparency in case of security incidents. No vulnerabilities or exposed sensitive data were detected in the HTML content. The absence of a cookie consent mechanism is a compliance gap under GDPR. Overall, the security maturity is moderate but could be improved with additional headers, policies, and user consent mechanisms.

Recommendations

  1. Implement a GDPR-compliant cookie consent banner and policy to enhance privacy compliance.
  2. Add security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to strengthen web security.
  3. Publish a clear security policy and incident response contact information to improve transparency and trust.
  4. Consider adding a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  5. Regularly audit and update third-party libraries and CMS components to mitigate potential vulnerabilities.

Technical notes

Notes

The website is built on TYPO3 CMS, a robust and widely used content management system, indicating a stable technical foundation. The use of Modernizr and JavaScript enhances compatibility and user experience across browsers. Hosting is provided via rzone.de, as indicated by the nameservers. The site is mobile optimized with responsive images and navigation. Performance is moderate with no obvious issues but could benefit from further optimization. SEO is supported by proper meta tags and structured data in JSON-LD format. Accessibility is basic but could be improved with additional ARIA attributes and semantic markup. No analytics or tracking scripts were detected, indicating minimal user tracking and a privacy-conscious approach.
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.
