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

The website www.plzen28rijen.eu is an official municipal event site dedicated to the annual celebrations of the founding of the Czechoslovak Republic in Plzeň, Czech Republic. It provides detailed information about the event program, venues, accompanying activities, and photo galleries. The site targets local residents and visitors interested in cultural and historical events, positioning itself as a trusted source for event-related information organized by the city government. The business model is focused on public cultural engagement and event promotion without commercial sales or e-commerce components. Technically, the website uses modern web technologies including HTML5, CSS, JavaScript, and Google Analytics for visitor tracking. It is mobile optimized with good navigation and SEO practices. The site employs HTTPS with a valid SSL certificate ensuring secure communications. Cookie consent mechanisms are implemented to comply with EU regulations, although no explicit privacy policy or terms of service pages were found. No CMS or hosting provider details were identified from the content. From a security perspective, the site demonstrates a good baseline with HTTPS and cookie consent but lacks advanced security headers and explicit security policies. No vulnerabilities or exposed sensitive data were detected. The absence of a privacy policy and incident response contact points are notable gaps. WHOIS data is unavailable due to EURid privacy protection, which is common and justified for this type of municipal website. No WAF or blocking mechanisms were detected, and the site content is fully accessible. Overall, the website is professionally designed, trustworthy, and serves its purpose well. Strategic recommendations include adding a comprehensive privacy policy, implementing security headers, providing clear contact information for security incidents, and enhancing accessibility compliance to improve user experience and regulatory adherence.

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

5 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

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics

      What to do: Document all third-party data sharing in your privacy policy

  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. 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

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 represents a government entity (Město Plzeň) organizing a large-scale cultural event attracting approximately 45,000 visitors annually. Its market position is strong locally as a trusted municipal organizer. The business model is non-commercial, focusing on public engagement and cultural heritage promotion. Key services include event scheduling, venue information, and multimedia galleries. The site leverages partnerships with local institutions and event sponsors, as indicated by linked domains such as www.plzen.eu and the design agency www.benes-michl.cz. Growth indicators include consistent annual events and expanding program offerings. The absence of direct commercial activities simplifies compliance but limits revenue streams to public funding or sponsorships.

Security posture

The security posture is moderate with HTTPS enforced and cookie consent implemented, reflecting compliance with basic EU data protection requirements. However, the lack of security headers such as Content-Security-Policy and absence of a published privacy policy or incident response contacts reduce the overall maturity. No vulnerabilities or exposed sensitive data were found, and no WAF or blocking mechanisms interfere with accessibility. The site would benefit from formalizing security policies, adding a security.txt file for vulnerability reporting, and improving accessibility features. GDPR compliance is partially addressed through cookie consent but incomplete without a privacy policy. Incident response readiness is unclear due to missing contact information.

Recommendations

  1. Publish a comprehensive privacy policy detailing data processing and GDPR compliance.
  2. Implement security headers including Content-Security-Policy, X-Frame-Options, and Referrer-Policy.
  3. Add explicit contact information for security incidents and consider a security.txt file.
  4. Enhance accessibility features to meet WCAG standards for broader inclusivity.
  5. Regularly review and update cookie consent mechanisms and data retention policies.

Technical notes

Notes

The website uses a clean and modern front-end stack with CSS and JavaScript, including Google Analytics for visitor tracking. The site is mobile responsive and SEO optimized with proper meta tags and Open Graph data. No CMS or backend technologies were identified from the HTML content. Performance appears moderate with preloading of CSS assets and asynchronous loading of analytics scripts. No broken links or errors were detected. Hosting provider details are not disclosed. The site could improve by adopting additional modern security headers and providing structured data (JSON-LD) for enhanced SEO and accessibility.
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.
