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

The website rostislavova4.cz represents a newly launched residential real estate project by PSN in the Nusle district of Prague. It offers detailed information about the property, including unit availability, pricing, financing options, and local amenities. The site is professionally designed with a modern tech stack including Bootstrap, Swiper, and Google services, ensuring a good user experience and mobile responsiveness. Security measures such as HTTPS and Google reCAPTCHA v3 are implemented, though some security headers and privacy compliance documents are missing. The domain registration data aligns well with the website content, indicating legitimacy and consistency. Overall, the site serves its business purpose effectively but should improve privacy and security documentation to enhance compliance and trust.

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

7 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. 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 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

PSN positions itself as a direct property owner and developer offering residential units with flexible financing and renovation options. The project targets families, couples, and investors interested in Prague's growing Nusle area. The business model focuses on direct sales without commission fees and leverages partnerships with financial institutions for mortgage facilitation. The website supports this with downloadable unit cards and detailed floor plans, enhancing buyer confidence. The presence of a partner domain and administrative backend indicates a structured operational ecosystem. The project is recent, consistent with the domain creation date, and reflects a medium-sized real estate development business.

Security posture

The website demonstrates a moderate to good security posture with HTTPS enforced and Google reCAPTCHA protecting forms. However, it lacks explicit privacy policies, terms of service, and some recommended security headers like Content-Security-Policy and X-Content-Type-Options. No vulnerabilities or exposed sensitive data were detected in the HTML content. The absence of a security.txt file or incident response contacts limits transparency for vulnerability reporting. Overall, the security measures are adequate for a marketing site but could be enhanced to meet higher compliance standards such as GDPR and NIS2.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service to improve legal compliance.
  2. Implement additional security headers including Content-Security-Policy and X-Content-Type-Options.
  3. Add a security.txt file to facilitate responsible vulnerability disclosure.
  4. Enhance accessibility features to improve compliance and user experience.
  5. Provide explicit incident response contact information for security issues.

Technical notes

Notes

The site uses a modern and stable technology stack with Bootstrap 5, Swiper for galleries, LightGallery for images, and Google APIs for maps and analytics. Hosting is via Websupport.cz, consistent with the domain's nameservers. Performance is moderate with asynchronous loading of scripts and responsive design. The site lacks a detectable CMS, suggesting a custom or static site approach. SEO is supported by proper meta tags and Open Graph data, though no JSON-LD structured data was found. Technical debt appears low, but improvements in accessibility and security headers are recommended to future-proof the platform.
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.
