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

The website visitzlin.eu serves as the official tourist information portal for the city of Zlín, Czech Republic. It provides comprehensive information about the city, including cultural events, historical background, practical visitor information, and local attractions. The portal targets tourists, local residents, and visitors interested in exploring Zlín and its surroundings. The business model is a government-operated informational service aimed at promoting tourism and local culture. Technically, the site employs a custom CMS with a modern JavaScript technology stack including jQuery and various UI libraries such as Slick Carousel and FullCalendar. It integrates Google services like Maps API, Analytics, Tag Manager, and reCAPTCHA for security and tracking. The site is hosted by Media4web, s.r.o., a Czech hosting provider, and uses HTTPS with a Content-Security-Policy header, indicating a good security baseline. From a security perspective, the site demonstrates good practices such as HTTPS enforcement and CAPTCHA protection on forms. However, it lacks some additional security headers and a visible cookie consent mechanism, which are important for GDPR compliance. No vulnerabilities or exposed sensitive data were detected in the provided content. The WHOIS data is transparent and consistent with the website's official city affiliation, supporting its legitimacy. Overall, the website is a well-maintained, regionally focused government portal with good content quality and technical implementation. It could improve privacy compliance and security posture by adding cookie consent, security policies, and additional headers. The risk level is low, with no critical issues detected.

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

11 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

  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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • 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

The portal positions itself as the primary digital gateway for tourism in Zlín, leveraging partnerships with local cultural institutions, the city government, and regional organizations. Its competitive advantage lies in official backing and comprehensive local content. Revenue streams are likely public funding and city budget allocations rather than direct monetization. The target customers include tourists, event attendees, and local citizens seeking information. Growth indicators include active event calendars and social media engagement. The partnership ecosystem is robust, linking to multiple regional and cultural sites, enhancing the portal's reach and credibility.

Security posture

The security maturity of the website is moderate to good. HTTPS is properly implemented, and a Content-Security-Policy header is present, reducing risks of mixed content and some injection attacks. The use of Google reCAPTCHA on subscription forms mitigates automated abuse. However, the absence of other security headers like X-Frame-Options and HSTS reduces defense-in-depth. No incident response or security policy pages were found, which limits transparency and preparedness. GDPR compliance is partial due to missing cookie consent mechanisms. No vulnerabilities or sensitive data leaks were observed, indicating a secure baseline but room for improvement in formal security governance.

Recommendations

  1. Implement a visible cookie consent banner to comply with EU cookie laws and improve privacy compliance.
  2. Add additional security headers such as X-Frame-Options, X-Content-Type-Options, Referrer-Policy, and Strict-Transport-Security.
  3. Publish a clear security policy and incident response contact information to enhance transparency and trust.
  4. Consider creating a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  5. Regularly audit third-party libraries and update them to mitigate potential vulnerabilities.

Technical notes

Notes

The website uses a custom CMS with a rich JavaScript ecosystem including jQuery and multiple UI plugins for calendars, sliders, modals, and maps. Google services are integrated for analytics, tag management, maps, and CAPTCHA. The site is hosted by a Czech provider Media4web, s.r.o., which aligns with the regional focus. Performance is moderate with some heavy slider images but generally good mobile responsiveness. SEO is supported by proper meta tags and Open Graph data. Accessibility is basic but could be enhanced. The technical stack is modern but could benefit from further optimization and security hardening.
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.
