Stará čistírna odpadních vod v Bubenči is a cultural heritage site located in Prague, Czech Republic, focusing on the historical wastewater treatment plant built between 1901 and 1906. The website serves to promote the site as a tourist attraction offering guided tours and event space rentals.

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

8 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

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 business targets visitors interested in historical and cultural experiences in Prague, leveraging its unique heritage site status. Revenue streams likely include event space rental and guided tours. The company maintains active social media channels on Facebook and Instagram to engage audiences. The website's business model is straightforward, focusing on cultural tourism and event hosting. There is no indication of large-scale operations or subsidiaries. The domain age aligns well with the business history, enhancing credibility. However, the absence of explicit privacy and terms policies may affect trust among privacy-conscious users.

Security posture

The website demonstrates a basic security maturity level with HTTPS enforced and a cookie consent mechanism in place, indicating GDPR awareness. However, the lack of security headers such as Content-Security-Policy and absence of a security policy or incident response information limits the security posture. No vulnerabilities or exposed sensitive data were detected in the provided content. The site would benefit from implementing security best practices and publishing vulnerability disclosure information to enhance trust and compliance.

Recommendations

  1. Implement comprehensive privacy and terms of service pages to improve GDPR compliance and user trust.
  2. Add security headers like Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  3. Publish a vulnerability disclosure policy or security.txt file to facilitate responsible reporting of security issues.
  4. Enhance accessibility features to improve usability for all users.
  5. Regularly audit and update third-party scripts and plugins to mitigate potential vulnerabilities.

Technical notes

Notes

The website uses a modern CMS (WordPress) with Elementor page builder and Yoast SEO plugin, indicating a mature digital infrastructure. It integrates Google Tag Manager and Facebook Pixel for analytics and marketing. The site is mobile optimized and has a clear navigation structure. Performance is moderate, with room for optimization. The absence of advanced security headers and limited accessibility features suggest areas for technical improvement. Hosting provider details are not explicitly identified. Overall, the technical setup supports the business needs but could be enhanced for security and performance.
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.
