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

Janáčkova filharmonie Ostrava is a well-established symphony orchestra based in Ostrava, Czech Republic, providing a rich program of classical music concerts, educational activities, and cultural events. The organization targets classical music enthusiasts and the cultural community, operating primarily as a non-profit entity. The website reflects a professional and consistent brand image with comprehensive event listings and ticketing integration. Technically, the website is built on WordPress using common plugins such as Contact Form 7, Cookie Law Info, and Google Analytics. It employs modern JavaScript libraries like jQuery and jCarousel for interactive elements and uses Google reCAPTCHA v3 to protect forms. The site is mobile-optimized and SEO-friendly, though performance is moderate. From a security perspective, the site uses HTTPS and has implemented cookie consent mechanisms aligned with GDPR. However, it lacks visible security headers and published security policies or incident response contacts. No vulnerabilities or exposed sensitive data were detected in the content. The absence of WHOIS data reduces trust assessment confidence but does not detract from the professional presentation. Overall, the website presents a low-risk profile with good privacy compliance and a strong cultural mission. Strategic improvements in security headers, incident response transparency, and WHOIS data availability would enhance trust and security 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.

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, Facebook, Twitter, YouTube

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

  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 Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1
  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

Janáčkova filharmonie Ostrava holds a significant cultural position in the Czech Republic as a regional symphony orchestra with a long history. Its business model focuses on delivering live orchestral performances, educational concerts, and cultural programming, supported by ticket sales and merchandise. The organization maintains partnerships with local government and cultural entities, as evidenced by linked domains. The website's content and structure indicate a focus on audience engagement through event promotion and digital ticketing. Growth indicators include active social media presence and a modernized web platform. The lack of explicit financial or organizational data limits deeper business insights.

Security posture

The website demonstrates a moderate to good security posture with HTTPS enforced and use of Google reCAPTCHA to protect user input forms. Cookie consent is implemented with granular categories, supporting GDPR compliance. However, the absence of security headers such as Content Security Policy, HSTS, and X-Frame-Options is a gap. No published security or incident response policies were found, and no security.txt or vulnerability disclosure mechanisms are present. The site does not expose sensitive data or use outdated libraries visibly. Overall, the security maturity is adequate for a cultural organization but could be improved with standard best practices and transparency.

Recommendations

  1. Implement HTTP security headers including Content Security Policy (CSP), HSTS, X-Frame-Options, and X-XSS-Protection to enhance protection against common web attacks.
  2. Publish a clear security policy and incident response contact information on the website to improve transparency and readiness.
  3. Add a security.txt file to facilitate responsible vulnerability disclosure and improve trust with security researchers.
  4. Regularly audit and update WordPress core, themes, and plugins to mitigate risks from known vulnerabilities.
  5. Enhance accessibility features to meet recognized standards and improve user experience for all visitors.

Technical notes

Notes

The website is built on WordPress CMS with a modern front-end stack including jQuery, jCarousel, and SimpleLightbox for UI components. It uses Google reCAPTCHA v3 for spam protection and integrates Google Analytics for visitor tracking. The site employs a cookie consent plugin compliant with GDPR. Performance is moderate with some optimization potential. Mobile responsiveness is good, and SEO meta tags and structured data are properly implemented. Hosting provider details are not evident from the content. The technical setup is typical for a mid-sized cultural organization website with room for security and performance enhancements.
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.
