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

7 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. 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 SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

  3. 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

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

Business profile

Crownd Estates GmbH is positioned in the luxury real estate market in Vienna, offering property sales, investment opportunities, and acquisition services. Their business model revolves around high-value real estate projects, targeting wealthy investors and buyers. The company leverages a modern web presence with video and image-rich content to attract and engage clients. The absence of privacy and terms policies suggests an area for compliance improvement. The company appears to be a small-sized entity with no visible parent or subsidiary companies. Their marketing ecosystem includes Microsoft Dynamics CRM and Usercentrics, indicating a focus on customer relationship management and privacy compliance. The website's clear project listings and professional branding support a high trust level in the market.

Security posture

The website demonstrates a strong security posture with enforced HTTPS, comprehensive security headers including CSP, and no exposed sensitive data. The use of Usercentrics for cookie consent shows attention to privacy compliance. However, the lack of a published privacy policy, terms of service, and vulnerability disclosure policy represents compliance gaps and potential risk areas. No incident response contacts or security@/abuse@ emails were found, which could hinder timely security incident handling. The site uses modern frameworks and CDNs, reducing attack surface and improving resilience. Overall, the security maturity is good but could be enhanced by formalizing policies and incident response mechanisms.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service to improve legal compliance and user trust.
  2. Implement and publicize a vulnerability disclosure policy or security.txt file to facilitate responsible security reporting.
  3. Add incident response contact information such as security@ or abuse@ email addresses.
  4. Enhance accessibility features to meet WCAG standards and improve inclusivity.
  5. Regularly review and audit third-party scripts and libraries to mitigate potential vulnerabilities.

Technical notes

Notes

The website is built using Next.js and React, leveraging server-side rendering and modern JavaScript modules for performance and SEO benefits. Hosting on Microsoft Azure with Imgix for image CDN ensures scalable and optimized content delivery. The integration of Usercentrics provides GDPR-compliant cookie consent management. Video content is embedded with autoplay and muted attributes, enhancing user engagement. The site uses Splide.js for carousels, providing smooth UI interactions. Performance is moderate with good mobile optimization and SEO meta tags. No standard CMS detected, indicating a custom or proprietary solution. Technical risks are minimal but include the need for continuous monitoring of third-party dependencies and compliance documentation.
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.
