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

The website webnem.cz is operated by DALTEN media s.r.o., a Czech company specializing in providing custom web presentation services for real estate properties. The service enables real estate agents and property sellers to create dedicated websites for their listings, enhancing marketing and SEO capabilities. The business model is subscription-based, charging monthly fees for property websites and annual fees for domain registration. The company leverages over 20 years of experience and partnerships with multiple real estate platforms, positioning itself as a trusted provider in the Czech real estate market. Technically, the website uses modern JavaScript libraries including jQuery and Google Analytics for tracking, with a responsive design optimized for mobile devices. Cookie consent management is implemented with granular user controls, ensuring GDPR compliance. Hosting and domain registration are consistent with the registrar REG-WEBGLOBE, and the domain age aligns with the company's founding date. From a security perspective, the site enforces HTTPS and includes cookie consent mechanisms, but lacks explicit security headers such as CSP or HSTS. No incident response or security policy information is published, representing an area for improvement. No vulnerabilities or exposed sensitive data were detected in the provided content. Overall, the website presents a professional and trustworthy front with good content quality and business credibility. The main risks relate to the absence of published security policies and some missing security headers. Strategic improvements in these areas would enhance the security posture and compliance maturity.

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

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

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

DALTEN media s.r.o. operates in the real estate sector, focusing on digital marketing services for property listings. Their competitive advantage lies in offering individualized property websites with SEO and marketing features, integrated with established real estate portals like realitymix.cz. Revenue streams include monthly subscription fees and domain registration charges. The target customers are real estate agents and property sellers seeking to differentiate their listings. The company maintains a strong partnership ecosystem with multiple real estate platforms and related services, enhancing market reach. The business shows growth potential through digital service expansion and leveraging its 20+ years of experience.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforced and GDPR-compliant cookie consent. However, the absence of explicit security headers such as Content-Security-Policy, X-Frame-Options, and HSTS reduces defense-in-depth. No incident response contacts or security policies are published, which limits transparency and preparedness. Data collection via forms includes required consent, but no advanced security controls are evident. Overall, the security posture is adequate for the business type but could be improved by adopting best practices in HTTP headers and publishing security documentation.

Recommendations

  1. Implement security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Publish a clear security policy and incident response contact information to improve transparency and readiness.
  3. Regularly audit and update third-party libraries to avoid vulnerabilities.
  4. Enhance accessibility features to improve compliance and user experience.
  5. Maintain and document data retention policies and privacy compliance measures.

Technical notes

Notes

The website uses a modern JavaScript stack with jQuery and Google Analytics, combined with responsive design techniques likely based on Bootstrap. Hosting is managed via REG-WEBGLOBE, consistent with the registrar data. Performance is moderate with some lazy loading of images, but some images show loading errors which could be optimized. SEO is supported by proper meta tags and structured navigation. No CMS was detected, indicating a custom or static site build. Accessibility is basic and could be improved. Overall, the technical infrastructure is solid but could benefit from performance tuning and enhanced accessibility.
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.
