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

Kancelare.cz operates as a leading Czech online platform specializing in office and coworking space rentals primarily in Prague, Brno, and Ostrava. The website offers a comprehensive listing service for commercial real estate, supplemented by relevant news and articles targeting businesses and individuals seeking workspace solutions. The platform maintains a strong market position within the Czech Republic's real estate sector, supported by a professional and user-friendly website design. Technically, the site employs modern JavaScript frameworks and integrates multiple third-party services such as Google Analytics, Google Tag Manager, Mailchimp, and Cookiebot, indicating a mature digital infrastructure. Security posture is solid with HTTPS enforced and cookie consent mechanisms in place, although explicit security headers and incident response information are absent. Overall, the site demonstrates good compliance with privacy regulations including GDPR. However, the absence of WHOIS data limits domain trust verification, suggesting a need for improved transparency. Strategic recommendations include enhancing security headers, publishing security policies, and providing clear contact information for security incidents.

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

5 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

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook, LinkedIn, Google APIs

      What to do: Document all third-party data sharing in your privacy policy

  2. 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';…
  3. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security

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 platform targets the commercial real estate market in the Czech Republic, focusing on office and coworking space rentals. Its business model revolves around providing a marketplace and informational resource for tenants and landlords, generating revenue likely through advertising and listing fees. The presence of social media channels and regular content updates indicates active engagement with its audience. The company appears to be medium-sized with a specialized niche in real estate. No parent or subsidiary companies were identified. The platform's competitive advantage lies in its localized focus and comprehensive service offering. Growth indicators include frequent news updates and integration of modern marketing tools. Partnerships with advertising and analytics providers support its operational ecosystem.

Security posture

The website enforces HTTPS, uses cookie consent banners, and integrates monitoring tools like New Relic, reflecting a baseline security maturity. However, the lack of explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options represents an area for improvement. No security policy or incident response contact information is published, which could hinder effective vulnerability management and incident handling. No vulnerabilities or exposed sensitive data were detected in the HTML content. The site would benefit from formalizing its security posture through documented policies and enhanced header configurations. Compliance with GDPR is evident through privacy and cookie policies. Overall, the security posture is good but could be elevated to excellent with additional measures.

Recommendations

  1. Implement comprehensive security headers including CSP, X-Frame-Options, and X-Content-Type-Options to mitigate common web vulnerabilities.
  2. Publish a clear security policy and incident response plan accessible to users and security researchers.
  3. Provide explicit contact channels for reporting security incidents or vulnerabilities, such as security@ or abuse@ email addresses.
  4. Regularly audit and update third-party scripts to minimize risks from external dependencies.
  5. Enhance WHOIS transparency to improve domain trustworthiness and legitimacy perception.

Technical notes

Notes

The website uses a modern JavaScript-based frontend with asynchronous loading of analytics and marketing scripts. Integration with Google Tag Manager, Google Analytics, Mailchimp, and Cookiebot indicates a sophisticated approach to user tracking and consent management. The site loads Google Maps API for location services and uses slick slider for content presentation. Performance is moderate with some optimization potential. Mobile responsiveness is good, but accessibility features are basic. No CMS was explicitly detected, suggesting a custom or proprietary platform. Hosting provider details are not evident from the HTML content. Overall, the technical infrastructure supports a professional user experience but could benefit from enhanced accessibility 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.
