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

Most-katalog.cz is a regional online business directory focused on companies and services in the Most region of the Czech Republic. It operates as part of the larger Česko-Katalog.cz network, providing categorized listings and search functionality for businesses. The website targets both consumers and businesses seeking local company information and advertising opportunities. Technically, the site uses common web technologies such as jQuery, Google Analytics, and Facebook SDK, hosted likely via Czech providers consistent with its regional focus. The site is accessible via HTTPS and includes basic SEO and navigation features, though mobile optimization and accessibility are basic. Security posture is moderate with HTTPS enabled but lacks advanced security headers and cookie consent mechanisms. Privacy and terms of service pages are present, indicating some compliance with GDPR, but no explicit incident response or vulnerability disclosure information is found. Overall, the site is legitimate, stable, and safe for general audiences, but could improve in security and privacy compliance.

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

    • 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

    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 Strict-Transport-Security header

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

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 operates as a small-sized online directory serving the Most region and broader Czech market. Its competitive advantage lies in its integration within a national network of regional directories under Česko-Katalog.cz. Revenue likely derives from advertising and premium listings. The target customers include local businesses seeking visibility and consumers searching for company information. The partnership ecosystem includes related regional directories and external service providers linked in the footer. Growth indicators are limited from the data but the domain age and network presence suggest established operations. Strategic observations include the need to enhance privacy compliance and security posture to maintain trust and regulatory adherence.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enabled and no visible exposed sensitive data. However, it lacks important security headers such as Content-Security-Policy and HSTS, which are critical for mitigating common web attacks. There is no evidence of a formal security policy, incident response contacts, or vulnerability disclosure mechanisms. GDPR compliance is partially addressed via a privacy policy but cookie consent is missing. The absence of direct contact information and security framework references indicates limited security culture maturity. Business impact of these gaps includes potential regulatory risk and vulnerability to web-based attacks. Improvements in security headers, cookie consent, and incident response readiness are recommended.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and HSTS.
  2. Add a cookie consent banner/mechanism to comply with GDPR and ePrivacy regulations.
  3. Publish clear incident response and vulnerability disclosure information to enhance trust and readiness.
  4. Enhance mobile optimization and accessibility to improve user experience and SEO.
  5. Provide clear and accessible contact information for business and security inquiries.

Technical notes

Notes

The website uses a traditional web stack with jQuery and third-party scripts like Google Analytics and Facebook SDK. The HTML structure is basic but functional with multiple CSS stylesheets linked from the parent domain. Hosting is consistent with Czech providers, and HTTPS is properly configured. Performance is moderate with no explicit indicators of slow loading but no advanced optimization detected. The site lacks modern frameworks or CMS indications, suggesting a custom or legacy platform. Technical debt is moderate, with opportunities for modernization including responsive design improvements, accessibility enhancements, and security header implementation. These improvements would reduce technical risks and improve operational stability.
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.
