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

Netkatalog.cz operates as the largest regional business directory in Eastern Bohemia, Czech Republic, providing a comprehensive database of over 660,000 Czech companies. The platform offers verified company listings, user ratings from Google and Facebook, and generates significant monthly inquiries, positioning itself as a trusted lead generation service. The business is owned by Netpromotion group s.r.o., with a history dating back to 2005, indicating a mature presence in the regional market. Technically, the website employs modern JavaScript and tracking technologies such as Google Tag Manager and Cloudflare Insights, hosted behind Cloudflare infrastructure, ensuring good performance and mobile optimization. Security posture is solid with HTTPS enforced and secure form handling, though it lacks advanced security headers and explicit incident response policies. Privacy compliance is basic with privacy and cookie policies present but missing a consent mechanism. The absence of WHOIS data for the domain is a notable concern impacting domain legitimacy verification. Overall, the website is professional, trustworthy, and well-positioned in its niche but would benefit from enhanced security and compliance transparency.

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

9 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. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  3. 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

      Forces HTTPS connections

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

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • 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

Netkatalog.cz targets regional businesses and consumers in the Czech Republic seeking verified company information. Its business model centers on providing a trusted directory service combined with lead generation, leveraging user ratings and advisor verification to build trust. The company benefits from a long operational history and a strong market position in the regional directory sector. Revenue likely derives from business listings and advertising. The parent company, Netpromotion group s.r.o., supports the platform and related services including a corporate blog. The ecosystem includes partnerships with Google services and Cloudflare for analytics and hosting. Strategic growth could focus on expanding digital marketing tools and enhancing compliance to attract more business clients.

Security posture

The website demonstrates a moderate to good security maturity level with HTTPS enforced and secure form inputs. However, the lack of security headers such as Content Security Policy, HSTS, and X-Frame-Options reduces defense-in-depth. No incident response or security policy pages are published, indicating limited transparency in security governance. Privacy policies exist but lack explicit cookie consent mechanisms, which may be a GDPR compliance gap. No vulnerabilities or exposed sensitive data were detected in the HTML content. The use of third-party scripts like Google Tag Manager and Cloudflare Insights introduces some risk that should be regularly audited. Overall, the security posture is adequate for the business type but could be improved with better headers, incident response readiness, and privacy controls.

Recommendations

  1. Implement comprehensive security headers including CSP, HSTS, and X-Frame-Options to enhance protection against common web attacks.
  2. Publish explicit incident response and security policy documentation to improve transparency and preparedness.
  3. Add a cookie consent banner/mechanism to ensure full GDPR compliance and user privacy control.
  4. Regularly audit third-party scripts and dependencies to mitigate supply chain risks.
  5. Enhance accessibility features to improve usability for all users and comply with standards.

Technical notes

Notes

The website uses modern JavaScript with asynchronous loading of Google Tag Manager and Cloudflare Insights scripts, indicating a focus on performance and analytics. The site is hosted behind Cloudflare, benefiting from CDN and security features. The HTML structure is valid and includes proper meta tags for SEO and social media sharing (Open Graph and Twitter cards). Mobile optimization is good with responsive images and viewport settings. However, no CMS or framework is explicitly detected, suggesting a custom or minimal platform. Performance is moderate with some room for improvement in accessibility and security headers. The technical stack supports the business model well but could be modernized further with enhanced security and compliance features.
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.
