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

Národní Realitní Holding is a Czech Republic-based real estate holding company focused on elevating the quality and reputation of the local real estate market. The company provides a portfolio of brands, broker training, unique real estate tools, and advisory services aimed at real estate agencies and brokers. Their market position is supported by strategic partnerships with key industry bodies such as the Realitní komora České republiky and the Realitní Akademie České Republiky. The website content is professionally presented, targeting real estate professionals and property clients within the Czech market. Technically, the website employs a modern JavaScript stack including jQuery, Google Maps API, and Fancybox for media display. The site is mobile optimized with good SEO practices but lacks some advanced accessibility features. Security posture is moderate with HTTPS enabled and cookie consent implemented; however, no security headers were detected and no published security or privacy policies were found, which are areas for improvement. The absence of WHOIS data for the domain reduces the ability to fully verify domain legitimacy and registration details, which impacts trust assessment. Despite this, the website's professional presentation, clear contact information, and strategic partnerships indicate a legitimate business operation. Overall, the site scores well on content quality and business credibility but should improve privacy compliance and security practices to enhance trust and reduce risk.

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

  2. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  3. 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • 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';…

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 in the Czech Republic, offering services that include brokerage support, broker training, and proprietary real estate software tools. Their business model leverages a portfolio of brands and strategic partnerships to provide comprehensive services to real estate professionals and clients. The target customers are real estate agencies, brokers, and property buyers/sellers. The company demonstrates growth potential through active recruitment of leaders and expansion of unique tools. Partnerships with industry bodies enhance credibility and market reach. Revenue streams likely include training fees, software licensing, and brokerage commissions. The company maintains a professional online presence with clear branding and service descriptions, positioning itself as a key player in the Czech real estate market.

Security posture

The website employs HTTPS ensuring encrypted communication, which is a fundamental security requirement. Cookie consent mechanisms are implemented, indicating awareness of privacy regulations. However, the absence of security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options represents a security gap that could expose the site to clickjacking, MIME sniffing, and other attacks. No forms were detected, reducing risk of input-based vulnerabilities, but third-party scripts like Google Analytics and advertising pixels introduce potential privacy and security considerations. The lack of published security policies or incident response contacts limits transparency and preparedness. Overall, the security posture is moderate but would benefit from enhanced HTTP headers, documented policies, and regular security audits.

Recommendations

  1. Implement comprehensive privacy and cookie policies accessible from the website footer or dedicated pages.
  2. Add security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to harden the site against common web attacks.
  3. Publish a security policy and incident response contact information to improve transparency and readiness.
  4. Conduct regular audits of third-party scripts and dependencies to identify and mitigate vulnerabilities.
  5. Improve accessibility features to meet recognized standards and enhance user experience for all visitors.

Technical notes

Notes

The website uses a combination of jQuery, jQuery UI, Underscore.js, Google Maps API, and Fancybox for interactive and media features. CSS is modularized with reset, grid, and style sheets. The site is responsive and mobile optimized with viewport meta tags and adaptive navigation menus. Google Analytics and Google Tag Manager are used for analytics, alongside Google Ads and Seznam retargeting for marketing. The site lacks a detected CMS, suggesting a custom or static site architecture. Performance is moderate with some potential for optimization. No hosting provider information was found. The technical stack is modern but could benefit from updated security configurations and enhanced 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.
