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. 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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • 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 leverages a modern web technology stack including Next.js and React, complemented by Chakra UI for design consistency. Integration with marketing and analytics tools such as Google Analytics, Microsoft Clarity, and Cookiebot indicates a focus on user behavior insights and compliance with cookie regulations. The absence of explicit privacy and terms of service pages suggests an area for improvement in regulatory compliance. The platform's market position as the largest rental offer aggregator in the Czech Republic provides competitive advantages in user reach and data volume. However, the lack of publicly available WHOIS data limits transparency regarding domain ownership and age, which could impact trust perceptions.

Security posture

The website enforces HTTPS, ensuring encrypted communications, and employs cookie consent mechanisms to comply with privacy regulations. However, the absence of visible security headers and explicit security policies reduces the overall security maturity. No vulnerabilities or exposed sensitive data were detected in the HTML content. The use of third-party scripts necessitates ongoing monitoring to mitigate potential risks. The platform currently lacks dedicated incident response contact channels or security certifications, which are recommended for enhancing trust and readiness against security incidents.

Recommendations

  1. Implement and publish comprehensive privacy policy and terms of service pages to enhance compliance and user trust.
  2. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to strengthen security posture.
  3. Provide clear contact information including security incident response channels to improve transparency and readiness.
  4. Regularly audit and update third-party scripts to prevent vulnerabilities and ensure data protection.
  5. Enhance accessibility features to meet compliance standards and improve user experience for all visitors.

Technical notes

Notes

The website is built on a modern, performant technology stack with server-side rendering via Next.js and a component-based UI using React and Chakra UI. It integrates multiple analytics and marketing tools, including Google Tag Manager and Microsoft Clarity, to monitor user engagement and optimize marketing efforts. The site is mobile-optimized and demonstrates good SEO practices with appropriate meta tags and Open Graph data. Performance is moderate, with potential for improvement through optimization of third-party scripts and resource loading. The absence of a detected CMS suggests a custom or headless architecture. Overall, the technical infrastructure supports a scalable and user-friendly platform but would benefit from enhanced security configurations and compliance documentation.
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.
