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

12 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

The business model centers on an online directory service generating revenue likely through advertising and promotional listings. The site maintains a consistent brand presence across multiple Czech regional catalogs under the Česko-Katalog.cz umbrella. Its market position is that of a local/regional directory with a focus on Plzeň and surrounding areas. The platform's competitive advantage lies in its localized content and established domain age. However, the absence of direct contact information on the main page and limited advanced features may constrain user engagement. The partnership ecosystem includes related regional catalogs and external service providers linked in the footer.

Security posture

The website enforces HTTPS and includes Google site verification, indicating basic security hygiene. However, no explicit security headers such as Content-Security-Policy or HSTS were detected, and there is no visible security or incident response policy. The forms present are minimal and lack visible advanced security controls. Tracking scripts from Google Analytics and Facebook SDK are used without a clear cookie consent mechanism, which may pose compliance risks under GDPR. Overall, the security posture is moderate but could be improved by implementing security headers, explicit privacy controls, and incident response information.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and HSTS to enhance protection against common web attacks.
  2. Add a clear cookie consent banner/mechanism to comply with GDPR and improve user privacy transparency.
  3. Publish explicit security and incident response policies with contact channels for reporting security issues.
  4. Enhance contact information visibility to improve business credibility and user trust.
  5. Consider modernizing the technical stack and improving mobile responsiveness and accessibility for better user experience.

Technical notes

Notes

The website uses a traditional web stack with jQuery and multiple CSS stylesheets hosted on the parent domain. Google Analytics and Facebook SDK are integrated for analytics and social features. The domain is hosted under Czech registrar REG-INTERNET-CZ with DNS servers ns.forpsi.net and ns.forpsi.it, indicating local hosting. Performance is moderate with basic mobile optimization. The site lacks a known CMS, suggesting a custom or legacy platform. SEO is basic with meta tags present but no advanced structured data or Open Graph tags detected. Accessibility features are minimal but navigation is clear. There is room for modernization and technical improvements to enhance performance and security.
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.
