The company is an established real estate developer in the Czech Republic with a history dating back to 1991. The website targets potential home buyers interested in modern, comfortable living spaces with amenities such as private terraces, underground garages, and electric car charging. The business model focuses on property sales supported by financing partnerships, notably with Hypoasistent s.r.o. The site content is professionally presented, with clear navigation and comprehensive contact options, including forms and direct communication channels. Technically, the website employs modern front-end technologies including Bootstrap, jQuery, Swiper, and LightGallery, along with Google Maps integration. Hosting and domain registration are consistent and reliable, with SSL enabled ensuring secure connections. The site includes GDPR-compliant privacy and cookie policies with explicit user consent mechanisms. Analytics and marketing tools such as Google Tag Manager and Seznam tracking are used responsibly. Security posture is solid with HTTPS and secure form handling, though the absence of explicit security headers suggests room for improvement. No vulnerabilities or suspicious activities were detected. The domain WHOIS data aligns well with the business claims, indicating legitimacy and transparency.

Strategic enhancements in security headers and incident response disclosures could further strengthen the security posture and user 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

Business profile

PSN s.r.o. holds a strong market position as a reputable real estate developer in the Czech Republic, leveraging a long operational history since 1991. The Rezidence Maroldka project targets mid to upper-market residential buyers seeking modern urban living in Prague. The company benefits from strategic partnerships, such as with Hypoasistent s.r.o. for financing solutions, enhancing customer acquisition and satisfaction. The business model is primarily sales-driven, supported by digital marketing and direct client engagement through the website. The presence on major social media platforms and transparent contact information supports brand credibility and customer trust. Growth indicators include active property listings and financing options, while the website's technical infrastructure supports scalability and user engagement.

Security posture

The website demonstrates a mature security posture with mandatory HTTPS encryption and secure form validation practices. GDPR compliance is evident through explicit consent checkboxes and detailed privacy policy references. However, the lack of visible security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options represents a potential area of vulnerability that could be exploited in advanced attacks. No signs of malware, phishing, or exposed sensitive data were found. Incident response and vulnerability disclosure mechanisms are not publicly documented, which could delay mitigation in case of security incidents. Overall, the security culture appears adequate but would benefit from formalized policies and enhanced technical controls.

Recommendations

  1. Implement comprehensive HTTP security headers including CSP, HSTS, X-Frame-Options, and X-Content-Type-Options.
  2. Publish a security policy and incident response contact information to improve transparency and readiness.
  3. Establish a security.txt file to facilitate responsible vulnerability disclosure.
  4. Regularly audit and update third-party libraries to mitigate risks from known vulnerabilities.
  5. Enhance accessibility features to improve compliance and user experience for all visitors.

Technical notes

Notes

The website uses a modern and well-supported technology stack including Bootstrap 5.3.2 for responsive design, jQuery 3.6.1 for DOM manipulation, Swiper for interactive sliders, and LightGallery for image galleries. Google Maps API integration provides location context. CookieConsent scripts ensure compliance with privacy regulations. Hosting appears stable with domain registration through Active24, a known Czech provider. Performance is moderate with potential for optimization in image loading and script management. SEO is supported by proper meta tags, Open Graph data, and JSON-LD structured data. The site is mobile-optimized and accessible at a basic level. Technical risks are minimal but could be reduced by adding security headers and improving 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.
