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

4 findings rated critical or high. Fix these first.

  1. 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';…

  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 Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

  3. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

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 targets property sellers, buyers, and renters in southern Germany and nationwide, leveraging over 30 years of market experience. Its business model focuses on personalized real estate brokerage services, including valuation, marketing, and transaction support. The website reflects a regional market position with a small-sized company profile. The use of immoprofessional software indicates a tailored digital infrastructure for real estate operations. No evident partnerships or subsidiaries are disclosed. The company maintains transparency through legal and contact information, supporting customer trust and regulatory compliance.

Security posture

The website enforces HTTPS and uses secure POST methods for login forms, indicating a baseline security standard. Cookie consent and privacy policies are present, supporting GDPR compliance. However, no advanced security headers (e.g., CSP, X-Frame-Options) were detected in the HTML content. There is no published security policy or vulnerability disclosure page, and no incident response contact emails were found. No vulnerabilities or exposed sensitive data were identified in the source. Overall, the security posture is adequate for a small real estate business but could be improved with additional security best practices and transparency.

Recommendations

  1. Implement HTTP security headers such as Content-Security-Policy, X-Frame-Options, and X-XSS-Protection to enhance protection against common web attacks.
  2. Publish a dedicated security policy and vulnerability disclosure page to improve transparency and encourage responsible reporting.
  3. Add explicit incident response contact channels (e.g., security@ or abuse@ email addresses) to facilitate security communication.
  4. Regularly audit third-party scripts and libraries to ensure no vulnerabilities or outdated components are present.
  5. Enhance accessibility features and SEO metadata for improved user experience and search engine ranking.

Technical notes

Notes

The website uses a custom real estate CMS platform (immoprofessional) with frontend technologies including jQuery, LayerSlider, Slick Slider, FontAwesome, and LazySizes for image optimization. The site is mobile responsive and includes cookie consent management scripts. Performance is moderate with asynchronous loading of some scripts. The HTML structure is valid and SEO-friendly with meta tags for description, keywords, and viewport settings. No major technical debt or deprecated technologies were detected. Hosting details are not explicit but name servers indicate professional hosting related to immoprofessional services. Opportunities exist to modernize by adopting newer JavaScript frameworks and enhancing accessibility compliance.
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.
