0–100, higher is better. How it is calculated

Realitní kancelář Dachi is a well-established real estate agency operating primarily in Olomouc and the surrounding Czech regions, boasting 34 years of experience. The company offers a broad portfolio of real estate services including sales, rentals, new development projects, and client advisory, positioning itself as a leading local player with a strong market presence. The website reflects a professional business with comprehensive property listings, a dedicated team, and client testimonials, supporting its credibility and trustworthiness. Technically, the site employs modern web technologies such as Google Analytics, Google Tag Manager, and CookieFirst for consent management, and is mobile optimized with good SEO practices. However, the absence of WHOIS data and privacy policy pages slightly detracts from transparency and compliance. Security posture is adequate with HTTPS and consent mechanisms but lacks visible security headers and formal security policies. Overall, the site is safe, professional, and user-friendly, serving a general audience interested in real estate.

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

8 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

    • 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. 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 Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

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 in the real estate sector, focusing on brokerage and property management in the Olomouc region. Its business model includes property sales, rentals, and development projects, supported by a team of 15 experts. The firm targets individuals and businesses seeking real estate solutions locally. The website content and client references indicate a strong reputation and consistent branding. The lack of WHOIS data and privacy policy is a minor concern but does not undermine the evident operational maturity. Marketing and analytics tools are used moderately to support business growth and client engagement. No partnerships or subsidiaries were identified from the data provided.

Security posture

The website uses HTTPS, ensuring encrypted communication. Cookie consent is implemented, indicating awareness of privacy regulations. However, no explicit security headers such as Content-Security-Policy or X-Frame-Options were detected, which could improve protection against common web attacks. There is no published security policy or incident response contact, and no vulnerability disclosure or security.txt file was found. Forms appear to have validation but CSRF protection details are not visible. No vulnerabilities or exposed sensitive data were identified in the HTML content. Overall, the security posture is moderate but could be enhanced by adopting additional best practices and transparency measures.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service to improve compliance and user trust.
  2. Implement and verify security headers (CSP, X-Frame-Options, X-Content-Type-Options) to strengthen web security.
  3. Provide a security policy and incident response contact information to enhance transparency and readiness.
  4. Consider publishing a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  5. Ensure all forms have robust CSRF protection and input sanitization to prevent injection attacks.

Technical notes

Notes

The website is built using a combination of jQuery, Bootstrap 3.3.7, Slick Carousel, and the Nette PHP framework, indicating a mature but somewhat dated tech stack. Google Analytics and Tag Manager are used for tracking, and CookieFirst manages cookie consent. The site is mobile responsive and SEO optimized with proper meta tags and structured navigation. Performance is moderate, with some large image assets and multiple scripts loaded asynchronously. Accessibility is basic but present. No CMS was explicitly detected. Hosting provider details are not available from the data. Overall, the technical infrastructure supports the business needs but could benefit from modernization and enhanced security configurations.
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.
