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.

Priority findings

7 findings rated critical or high. Fix these first.

  1. GDPR outside view

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

PSN holds a significant position in the Czech real estate market, leveraging direct ownership and development of properties to offer competitive sales and rental services. Their business model integrates property development, revitalization, and comprehensive client services, including legal and financing assistance. The company targets a broad audience of residential and commercial clients, supported by a strong digital presence and partnerships with multiple project-specific domains. The website's content and structure indicate a mature organization with a focus on quality and customer engagement. Their marketing strategy includes active social media channels and analytics-driven insights, positioning them well for sustained growth and market responsiveness.

Security posture

The website exhibits a solid security posture with HTTPS enabled, integration of Google reCAPTCHA v3 to protect forms, and a cookie consent mechanism aligned with GDPR requirements. However, the absence of explicit security policies, incident response contacts, and a security.txt file suggests room for improvement in transparency and readiness for vulnerability disclosures. The use of reputable third-party services like Cloudflare for DNS and CDN enhances security and performance. No vulnerabilities or exposed sensitive data were detected in the HTML content. To elevate their security maturity, PSN should consider publishing detailed security policies and implementing additional HTTP security headers.

Recommendations

  1. Publish a dedicated security policy page and provide clear incident response contact information.
  2. Implement and explicitly declare HTTP security headers such as X-Frame-Options, Referrer-Policy, and Content-Security-Policy.
  3. Establish a security.txt file to facilitate responsible vulnerability disclosures.
  4. Conduct regular audits of third-party scripts and dependencies to mitigate potential vulnerabilities.
  5. Enhance website accessibility features to meet broader compliance standards and improve user experience.

Technical notes

Notes

The website is built on a modern technology stack including Bootstrap 4.3.1, jQuery, and various UI libraries like Slick Carousel and LightGallery. It uses the Nette Framework for form handling and AJAX, indicating a robust backend framework. Hosting and DNS are managed via Cloudflare, providing CDN and security benefits. Performance is moderate with lazy loading and asynchronous script loading implemented. SEO is well addressed with proper meta tags, Open Graph data, and JSON-LD structured data for enhanced search engine understanding. Mobile optimization is good, though accessibility features are basic and could be improved. Overall, the technical infrastructure supports a professional and scalable web presence.
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.
