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

    • High

      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

    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

      • OWASP A04:2025
      • ASVS V3.4.1
    • High

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 business operates a traditional real estate brokerage model supplemented by value-added services such as legal consulting and property valuation. Its market positioning is strengthened by certifications and ethical codes, enhancing trustworthiness. The company leverages partnerships and uses a specialized real estate software platform (Softreal). The target customer segments include property buyers, sellers, and renters in the Czech market. The website content and structure support lead generation through multiple contact forms and calls to action.

Security posture

The website employs HTTPS and integrates Google Tag Manager for analytics, indicating a baseline security posture. However, the absence of visible security headers such as Content-Security-Policy and Strict-Transport-Security suggests room for improvement. No incident response or vulnerability disclosure information is provided, and cookie consent mechanisms are missing, which may impact GDPR compliance. The site uses standard web technologies with no apparent vulnerable libraries detected in the HTML content. Overall, the security posture is moderate but could benefit from enhanced security controls and compliance features.

Recommendations

  1. Implement comprehensive security headers including CSP, HSTS, X-Frame-Options, and X-Content-Type-Options to mitigate common web vulnerabilities.
  2. Add a cookie consent banner and detailed cookie policy to ensure compliance with EU GDPR and ePrivacy Directive requirements.
  3. Establish and publish an incident response policy and contact channels for security issues to improve transparency and readiness.
  4. Regularly update all JavaScript libraries and dependencies to their latest secure versions to reduce vulnerability risks.
  5. Enhance accessibility features and SEO metadata to improve user experience and search engine visibility.

Technical notes

Notes

The website is built using a combination of jQuery, Bootstrap, and custom JavaScript, hosted on an unspecified provider but leveraging Google services for fonts, translation, and analytics. The CMS platform Softreal is used, indicating specialized real estate software integration. The site is mobile optimized with responsive design and includes interactive elements such as carousels and search forms. Performance is moderate with no major issues detected. However, the lack of advanced security headers and cookie consent mechanisms indicates technical debt in security and compliance areas.
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.
