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

Neviditelná výstava is a Czech-based exhibition website offering cultural experiences, ticket sales, and gift vouchers. The site targets a general audience interested in sensory and cultural exhibitions. The business appears to be small-sized and established since 2010, with a consistent domain registration and hosting aligned with its Czech origin. Technically, the website is built on WordPress using popular plugins such as WPBakery Page Builder and WPML for multilingual support. It employs Google Analytics and Tag Manager for tracking and uses Google reCAPTCHA for form security. However, the site lacks explicit privacy and cookie policies, which impacts its privacy compliance score. Security headers are not evident, suggesting room for improvement in security hardening. Overall, the website is professionally designed with good user experience and mobile optimization but needs enhancements in privacy and security disclosures.

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. 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"

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 operates in the cultural exhibition sector, focusing on immersive sensory experiences. Its business model revolves around ticket sales and gift vouchers, targeting visitors and cultural enthusiasts primarily in the Czech Republic. The presence of multilingual support indicates an intent to reach international visitors. The domain age and registration data support a stable market presence. The site does not display explicit trust indicators such as certifications or testimonials, which could be areas for growth. Marketing relies on Google services, and no affiliate or advertising networks are detected. The business ecosystem appears focused and niche, with no evident partnerships or subsidiaries.

Security posture

The website benefits from HTTPS encryption and uses Google reCAPTCHA to protect forms, indicating basic security awareness. However, the absence of security headers like Content-Security-Policy, X-Frame-Options, and others reduces its defense-in-depth posture. No vulnerability disclosure or security policy is published, limiting transparency and incident response readiness. The use of third-party scripts such as Google Analytics and Tag Manager introduces moderate tracking but no evident malicious or suspicious scripts. Overall, the security posture is moderate but could be significantly improved by implementing security headers, publishing security policies, and establishing vulnerability disclosure mechanisms.

Recommendations

  1. Publish a comprehensive privacy policy and cookie policy with GDPR compliance details.
  2. Implement and configure security headers to enhance protection against common web attacks.
  3. Add a security.txt file and a public vulnerability disclosure policy to improve transparency and incident response.
  4. Provide clear and accessible contact information including support and security contacts.
  5. Regularly audit and update all plugins and themes to mitigate vulnerabilities and maintain security.

Technical notes

Notes

The website is built on a mature WordPress platform with a modern tech stack including jQuery, WPBakery Page Builder, and WPML for multilingual content. It uses Google Fonts and Font Awesome for styling and icons. Performance is moderate with asynchronous loading of analytics scripts. Mobile optimization is good, and SEO meta tags are properly set. However, accessibility features are basic and could be enhanced. The hosting provider is consistent with the domain registrar and geographic location. No critical technical issues or errors were detected in the HTML content. Opportunities exist to improve security headers and privacy compliance to reduce technical debt and enhance trust.
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.
