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

The website bytysroubarenska.cz represents a new residential real estate development project in České Budějovice, Czech Republic, managed by RONDO obchodní a realitní společnost s.r.o. The project offers 22 modern apartments with terraces, parking, and storage, targeting individuals, couples, and families seeking quality urban living. The site is professionally designed with clear navigation and relevant content, supporting the sales and marketing of the development. Technically, the site uses a modern tech stack including Bootstrap and jQuery, hosted by WEDOS, and implements HTTPS with cookie consent mechanisms. However, it lacks explicit privacy policies, security headers, and incident response information, which are areas for improvement. Overall, the site is credible and functional, supporting the business goals effectively.

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

9 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

  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 Strict-Transport-Security header

      Forces HTTPS connections

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

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • 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

The company operates as a small real estate developer and agency focused on the South Bohemia region, particularly České Budějovice. Their business model centers on selling newly developed apartments with customization options. The website supports lead generation and customer engagement through detailed apartment listings, downloadable brochures, and direct contact information. The partnership with Realitní kancelář Rondo s.r.o. strengthens their market presence. The project timeline and domain registration align, indicating a legitimate and timely business initiative. The company leverages social media and retargeting advertising to reach potential buyers.

Security posture

The website demonstrates a basic security posture with HTTPS enabled and a cookie consent mechanism in place, indicating awareness of privacy regulations. However, the absence of security headers such as Content-Security-Policy and lack of published privacy or security policies reduce the overall security maturity. No forms collecting sensitive data are present on the homepage, minimizing immediate risk. The site does not provide incident response contacts or vulnerability disclosure information, which are recommended for enhanced security and trust. Overall, the security posture is adequate for a marketing site but could be improved to meet higher compliance and protection standards.

Recommendations

  1. Publish a comprehensive privacy policy page detailing data processing and GDPR compliance.
  2. Implement and configure security headers including Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options.
  3. Add a security.txt file or a vulnerability disclosure policy to facilitate responsible reporting.
  4. Provide clear incident response contact information, such as security@ or abuse@ email addresses.
  5. Regularly review and update cookie consent mechanisms and ensure transparency in data collection.

Technical notes

Notes

The website is built on a modern and widely supported technology stack including Bootstrap 4.5.2 and jQuery 3.5.1, ensuring responsive design and compatibility across devices. Hosting is provided by WEDOS, a reputable Czech hosting provider. The site loads a variety of CSS and JS assets for UI components, galleries, and carousels, contributing to a good user experience. SEO is supported by meta tags and canonical URLs. Performance is moderate, with room for optimization. Accessibility features are basic but present. No CMS is explicitly identified, but meta author indicates PolyWeb.cz, suggesting a custom or proprietary CMS. Overall, the technical infrastructure is solid but could benefit from enhanced security configurations and performance tuning.
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.
