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

The website brno-katalog.cz serves as a regional online business directory focused on companies and services in Brno and the broader Czech Republic. It provides categorized listings across multiple sectors, facilitating users to find firms and services locally. The platform is part of a larger network of regional catalogs under the parent domain cesko-katalog.cz, indicating a structured approach to regional business listings. The business model centers on offering promotional and listing services to companies, targeting both businesses and consumers seeking local service providers. Technically, the site employs a traditional web stack with jQuery, Google Analytics, and Facebook SDK integrations. The site is hosted under Czech domain registrars with appropriate HTTPS configuration, though it lacks advanced security headers and cookie consent mechanisms. The design and content quality are basic but functional, with moderate mobile optimization and SEO practices. Navigation is clear, and the site includes essential legal pages such as privacy policy and terms of service, though contact information is sparse on the main page. From a security perspective, the site benefits from HTTPS and asynchronous loading of tracking scripts but lacks explicit security headers like CSP or HSTS. No vulnerabilities or exposed sensitive data were detected in the provided content. Privacy compliance is partial, with GDPR-related pages present but no visible cookie consent. Incident response and security policy details are absent, indicating room for improvement in security governance. Overall, the website presents a moderately credible and functional business directory with basic technical and security implementations. Strategic enhancements in security headers, privacy compliance, and contact transparency would improve trust and compliance posture.

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.

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

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

Brno-katalog.cz operates as a niche regional business directory under the umbrella of cesko-katalog.cz, leveraging a networked approach to cover multiple Czech cities. Its competitive advantage lies in localized listings and categorization, appealing to SMEs and local consumers. The revenue model likely includes paid listings and advertising. The target customers are local businesses seeking visibility and consumers searching for services. The presence of multiple partner domains in the footer suggests a partnership ecosystem supporting cross-promotion. Growth indicators include domain age and network expansion. However, limited direct contact information and basic content quality may constrain user engagement and trust.

Security posture

The website demonstrates a foundational security posture with HTTPS enabled and no visible sensitive data leaks. However, the absence of key security headers such as Content-Security-Policy, X-Frame-Options, and HSTS reduces protection against common web attacks. The lack of a cookie consent mechanism and incident response contact points indicates gaps in GDPR compliance and security readiness. Tracking via Google Analytics and Facebook SDK is implemented but without transparent user consent. Overall, the security maturity is basic, suitable for a directory site but requiring enhancements to meet modern compliance and security standards.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and HSTS to strengthen web security.
  2. Add a cookie consent banner and detailed cookie policy to comply with GDPR and enhance user privacy transparency.
  3. Publish explicit incident response and security contact information to improve trust and readiness.
  4. Enhance contact information visibility on the website to improve business credibility and user trust.
  5. Regularly audit third-party scripts and tracking tools to ensure privacy compliance and minimize security risks.

Technical notes

Notes

The website uses a classic web technology stack with jQuery and asynchronous loading of Google Analytics and Facebook SDK scripts. CSS is loaded from a centralized parent domain, indicating shared styling resources across the network. The site is hosted under Czech registrars with stable DNS configuration. Performance is moderate with basic mobile optimization and accessibility features. SEO is basic with meta tags present but no structured data like JSON-LD or Open Graph tags detected. The site could benefit from modernization including responsive design improvements, enhanced accessibility, and adoption of modern JavaScript frameworks or CMS platforms for better maintainability.
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.
