ZLIN.CZ is a regional news and information portal serving the Zlín region in the Czech Republic. It provides up-to-date news, cultural events, sports coverage, and local information for residents and visitors. The website operates on a WordPress CMS platform, leveraging modern web technologies such as Bootstrap for responsive design and integrates advertising networks like Google AdSense and DoubleClick for revenue generation. The site employs cookie consent mechanisms to comply with privacy regulations, although explicit privacy and terms of service pages are not detected in the scanned content.

Overall, the website is professional, content-rich, and well-positioned as a local media outlet.

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

3 findings rated critical or high. Fix these first.

  1. 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 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';…
  2. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048
  3. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security

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 website targets local residents and visitors interested in regional news and events in the Zlín area. Its business model relies primarily on advertising revenue, supported by multiple ad slots from Google networks. The site maintains a consistent brand presence and offers a variety of content categories including news, culture, sports, and police/fire reports. The domain's long registration history since 1997 supports its credibility and market presence. The use of popular CMS and SEO tools indicates a focus on digital maturity and audience reach. However, the absence of direct contact information and formal policies may limit trust and compliance perception among users.

Security posture

The site enforces HTTPS and uses Google Tag Manager to control script loading, which is positive for security. Cookie consent is implemented, indicating awareness of privacy regulations. However, the lack of explicit security policies, incident response contacts, and vulnerability disclosure mechanisms represents gaps in security maturity. No vulnerable libraries or exposed sensitive data were detected. Security headers beyond basic ones are missing, which could be improved to harden the site against common web attacks. Overall, the security posture is moderate with room for enhancement in transparency and technical controls.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service pages accessible from the homepage.
  2. Add security headers such as Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to improve protection.
  3. Provide clear contact information including emails and phone numbers for general and security-related inquiries.
  4. Implement a security.txt file or vulnerability disclosure policy to facilitate responsible reporting.
  5. Regularly audit third-party scripts and advertising integrations to minimize privacy and security risks.

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.
