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

  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

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 as a local real estate agent specializing in the island of Föhr, leveraging its founder's local roots and extensive experience since 1995. Its competitive advantage lies in deep local market knowledge, personalized service, and a strong reputation evidenced by numerous client testimonials. The business model is commission-based brokerage with additional advisory services such as property valuation and financing guidance. Target customers include local residents, second-home buyers, and investors interested in Föhr properties. The website's content and references indicate a stable, small-sized operation with a focus on quality and trust. No evidence of partnerships or subsidiaries was found, suggesting an independent business. Growth indicators include a well-maintained website and active social media presence on Facebook.

Security posture

The website employs HTTPS, ensuring encrypted communication. A captcha mechanism protects the contact form against automated abuse. No security.txt or incident response contacts are published, which is common for small businesses but could be improved. Security headers like Content-Security-Policy and X-Frame-Options are not explicitly detected, representing an area for enhancement. No vulnerable libraries or exposed credentials were found in the HTML content. Privacy policy is comprehensive and GDPR compliant, but cookie consent is missing, which may pose compliance risks. Overall, the security posture is adequate but could benefit from implementing additional HTTP security headers and formalizing incident response information.

Recommendations

  1. Implement comprehensive HTTP security headers including Content-Security-Policy, X-Frame-Options, X-Content-Type-Options, and Referrer-Policy.
  2. Add a cookie consent banner and mechanism to comply with EU cookie regulations and enhance privacy compliance.
  3. Publish a security policy and incident response contact information to improve transparency and readiness.
  4. Regularly audit third-party scripts and dependencies to ensure no vulnerable libraries are introduced.
  5. Enhance accessibility features to improve compliance with WCAG standards and broaden user inclusivity.

Technical notes

Notes

The website is powered by TYPO3 CMS, a robust and widely used open-source content management system. It uses modern web fonts, Font Awesome Pro icons, and Google Maps API for location services. The site loads CSS assets in compressed form and uses lazy loading for images, indicating performance optimization efforts. The contact form uses a custom captcha solution from lichtflut.eu to prevent spam. The site is mobile responsive with a clear navigation structure. Hosting appears to be managed via domaincontrol.com DNS servers, likely GoDaddy. No analytics or tracking scripts were detected, indicating minimal user tracking. The site could improve by adding more comprehensive SEO metadata and accessibility attributes. Overall, the technical infrastructure is solid and appropriate for a small real estate business website.
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.
