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

9 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

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

  2. Security headers

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 leverages over 20 years of experience in real estate software to position RMIX MLS as a key tool for Czech real estate agents. Its business model focuses on SaaS offerings that enhance agent collaboration and portfolio management. The integration with RealityMIX.cz and related partner services creates a strong ecosystem, enhancing market reach and customer value. The platform's free access model with monetization through portfolio expansion fees and commissions indicates a sustainable revenue stream. The clear contact channels and detailed FAQ support customer engagement and trust. Strategic partnerships and a consistent brand identity reinforce market credibility.

Security posture

The website employs HTTPS and a comprehensive cookie consent system aligned with GDPR requirements, indicating a mature privacy approach. However, the absence of explicit security policies, incident response contacts, and security.txt files suggests room for improvement in transparency and readiness. The use of up-to-date libraries and no visible sensitive data exposure are positive indicators. Security headers are not explicitly detected, which could be enhanced to mitigate common web threats. Overall, the security posture is good but could benefit from formalized policies and additional technical controls.

Recommendations

  1. Implement standard HTTP security headers such as Content-Security-Policy, Strict-Transport-Security, X-Frame-Options, and X-XSS-Protection.
  2. Publish a clear security policy and provide dedicated incident response contact information on the website.
  3. Add a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Enhance accessibility features to improve compliance and user experience for all users.
  5. Regularly review and update third-party scripts and dependencies to minimize security risks.

Technical notes

Notes

The website uses a modern JavaScript stack including jQuery 3.6.0 and Google Tag Manager for analytics and marketing. It employs lazy loading for images and responsive design techniques, ensuring good mobile optimization. The site lacks a detected CMS, suggesting a custom or static site build. Performance is moderate with deferred script loading. SEO is supported by appropriate meta tags and structured navigation. Hosting provider details are not disclosed. Technical debt appears low, but security header implementation and accessibility improvements are recommended to enhance robustness and 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.
