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

      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

    • High

      Missing Strict-Transport-Security header

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

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 targets real estate agents in the Czech Republic, offering subscription-based personal website services integrated with RealityMIX.cz. Its competitive advantage lies in its long-standing experience, partnerships, and seamless integration with a leading real estate portal. Revenue likely derives from monthly subscriptions for website templates and hosting. The partnership ecosystem includes RealityMIX.cz and other real estate service providers. The business model focuses on ease of use, professional design, and domain/hosting management, appealing to agents seeking quick and credible online presence. Growth potential exists through expanding template offerings and deeper integrations. The company maintains a consistent brand and clear communication channels, supporting customer trust and retention.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and a comprehensive cookie consent mechanism supporting GDPR compliance. Form inputs require email and GDPR consent, reducing data privacy risks. However, the absence of explicit security headers like Content-Security-Policy and lack of published security or incident response policies represent areas for improvement. No vulnerabilities or exposed sensitive data were detected. The use of third-party scripts is controlled with integrity attributes where applicable. Overall, the security maturity is good but could be enhanced by adopting additional headers and publishing formal security policies and incident response contacts.

Recommendations

  1. Implement HTTP security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Publish a dedicated privacy and security policy page on the main domain to improve transparency and user trust.
  3. Provide clear incident response contact information (e.g., security@ or abuse@ email) to facilitate vulnerability reporting and response.
  4. Regularly audit and update third-party libraries and scripts to mitigate potential vulnerabilities.
  5. Enhance accessibility features and SEO metadata to improve user experience and search engine ranking.

Technical notes

Notes

The website employs a modern front-end stack including jQuery 3.6.0, Google Fonts, and Bootstrap-like responsive design. It uses deferred JavaScript loading and lazy loading for images, contributing to moderate performance. Google Analytics is integrated for user behavior tracking, complemented by a detailed cookie consent mechanism. The site lacks a detected CMS, suggesting a custom or static site build. Hosting provider details are not explicit. The site is mobile optimized with good navigation clarity. Technical debt appears low, but security header implementation and formal policy publication are opportunities for modernization. Overall, the technical infrastructure supports the business model effectively with room for incremental improvements.
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.
