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

  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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

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 positions itself as a leading real estate agent in the Czech Republic with a focus on quality over quantity in property listings. The business leverages digital marketing and client testimonials to build trust and attract clients. Revenue streams likely include commissions from property sales and consulting services. The target audience is local property owners and buyers, with a focus on premium real estate. The website's marketing ecosystem includes multiple tracking and retargeting tools, indicating an active digital marketing strategy. No partnerships or subsidiaries were identified from the domain or website content.

Security posture

The website enforces HTTPS and uses several security and analytics scripts loaded asynchronously, which is good practice. However, explicit security headers like Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options are not detected, representing an area for improvement. No vulnerabilities or exposed sensitive data were found in the HTML content. The absence of published security policies or incident response contacts is a compliance gap. Overall, the security posture is moderate but could be enhanced with additional headers and transparency.

Recommendations

  1. Publish a comprehensive privacy policy and cookie policy to improve GDPR compliance and user trust.
  2. Implement explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Provide clear incident response and security contact information on the website.
  4. Review and optimize performance to improve loading speed and accessibility features.
  5. Enhance transparency about data collection and retention policies related to analytics and marketing tools.

Technical notes

Notes

The website is built on WordPress CMS, utilizing jQuery and several third-party analytics and marketing scripts including Google Analytics, Facebook Pixel, Smartlook, Foxentry, and Leady. The hosting provider is Wedos, a Czech-based registrar and hosting service, consistent with the business location. The site uses modern SEO meta tags and Open Graph tags for social media integration. The design is responsive and mobile-friendly, with good navigation clarity. Some CSS and JavaScript optimizations could improve performance. Accessibility is basic but could be improved with ARIA attributes and better semantic markup.
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.
