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

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

    • 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. 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

Business profile

DALTEN media s.r.o. operates webnem.cz as a specialized service offering custom websites for real estate properties, targeting real estate professionals in the Czech Republic. The company leverages a subscription revenue model with clear pricing for monthly website fees and annual domain registration. The business benefits from a strong partnership ecosystem including realitymix.cz and rmixmls.cz, enhancing its market reach. The website's clear branding, partner logos, and contact information support credibility and customer trust. The company appears to be a small-sized entity with a focused niche in real estate marketing technology. Growth potential exists through integration with MLS systems and expanding marketing tools. The absence of a public terms of service or incident response policy suggests areas for operational maturity improvement.

Security posture

The website demonstrates a baseline security posture with HTTPS enforced and GDPR-compliant cookie consent mechanisms. The contact form includes required fields and explicit user consent for personal data processing. However, the lack of visible security headers such as Content-Security-Policy, X-Frame-Options, and HSTS reduces the overall security robustness. No explicit security or incident response policies are published, which may impact user trust and regulatory compliance. The use of third-party scripts like Google Tag Manager is standard but requires ongoing monitoring for vulnerabilities. No exposed sensitive data or known vulnerabilities were detected in the provided content. Overall, the security posture is moderate but could be enhanced by implementing recommended headers and publishing security policies.

Recommendations

  1. Implement security headers including Content-Security-Policy, X-Frame-Options, and HSTS to improve protection against common web attacks.
  2. Publish a dedicated security policy and incident response plan page to enhance transparency and preparedness.
  3. Regularly audit and update third-party scripts and libraries to mitigate vulnerabilities.
  4. Enhance accessibility features to improve compliance and user experience for all users.
  5. Consider adding a terms of service page to clarify user rights and obligations.

Technical notes

Notes

The website uses a modern JavaScript-based front end with jQuery 3.6.0 and Google Tag Manager for analytics. It employs Google Fonts and Bootstrap-like CSS classes for responsive design. Hosting is managed via REG-WEBGLOBE and Webglobe name servers, indicating a Czech hosting provider. Performance is moderate with some lazy loading images, though some images failed to load properly, indicating minor technical debt. SEO is supported by meta viewport tags and structured navigation with anchor links. No CMS was detected, suggesting a custom or static site build. Accessibility is basic with room for improvement. Overall, the technical infrastructure is adequate for the business purpose but could benefit from performance optimizations and enhanced 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.
