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

Palác Akropolis is a well-established cultural venue and club based in Prague, Czech Republic, with a domain age dating back to 1999. The website serves as a platform to showcase a diverse range of cultural events including music concerts, theater performances, jazz sessions, and other artistic projects. It targets a broad audience interested in cultural and nightlife activities. The business model revolves around event hosting, ticket sales, and cultural programming, positioning itself as a key player in the local cultural scene. Technically, the website employs a modern tech stack including jQuery, Google Tag Manager, Google Analytics, and a cookie consent management tool, ensuring compliance with privacy regulations such as GDPR. The site is mobile optimized and offers a good user experience with clear navigation and professional design. While no major CMS is detected, the site appears to be custom-built or uses a proprietary system. From a security perspective, the site enforces HTTPS and implements a comprehensive cookie consent mechanism with granular categories. However, some security headers like X-Frame-Options and Content Security Policy are not explicitly present, which could be improved. No vulnerabilities or exposed sensitive data were detected. Privacy compliance is strong, with a detailed privacy policy and cookie consent banner. Overall, the website is trustworthy, professional, and compliant with relevant privacy laws. It effectively supports the business goals of Palác Akropolis by providing event information, ticketing options, and engaging content. Strategic recommendations include enhancing security headers, continuing to monitor third-party scripts, and possibly adding explicit contact emails and phone numbers for improved user trust and support.

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.

Priority findings

7 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

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

Palác Akropolis holds a strong market position as a cultural venue in Prague with a long operational history since 1999. Its competitive advantage lies in its diverse programming across multiple cultural genres and its established brand presence. Revenue streams primarily come from ticket sales and event hosting. The target customer segments include local and international cultural enthusiasts, music fans, and theatergoers. The website's partnership ecosystem includes social media platforms and advertising networks like Google Ads. The business shows indicators of growth through active event scheduling and marketing efforts. Operationally, the company maintains a professional digital presence with compliance to privacy regulations, supporting sustainable market engagement.

Security posture

The website demonstrates a moderate to good security maturity level. HTTPS is enforced, and cookie consent is managed with user choice and GDPR compliance in mind. The absence of critical vulnerabilities or exposed sensitive data is positive. However, the lack of some security headers such as X-Frame-Options and Content Security Policy represents a gap that could be exploited in certain attack scenarios. No incident response or security policy pages were found, indicating potential areas for improvement in security governance and transparency. Overall, the security posture is adequate for the business type but could be enhanced with additional best practices and documentation.

Recommendations

  1. Implement additional security headers including X-Frame-Options, X-Content-Type-Options, and Content Security Policy to mitigate clickjacking and content injection risks.
  2. Publish a dedicated security policy and incident response information to improve transparency and preparedness.
  3. Regularly audit and update third-party scripts and libraries to avoid vulnerabilities.
  4. Consider adding explicit company contact emails and phone numbers on the website to enhance user trust and support.
  5. Maintain and update privacy and cookie policies to reflect any changes in data processing or regulatory requirements.

Technical notes

Notes

The website uses a combination of jQuery, Google Tag Manager, Google Analytics, and a third-party cookie consent library (orestbida/cookieconsent). The HTML structure is valid and includes meta viewport tags for mobile responsiveness. Performance is moderate, with asynchronous loading of scripts to improve load times. The site does not appear to use a common CMS, suggesting a custom or proprietary platform. SEO is basic but functional, with appropriate meta tags and structured navigation. Accessibility features are minimal but present. The site is hosted on an HTTPS-enabled server, ensuring encrypted communications. Opportunities exist to modernize the tech stack by reducing reliance on older libraries like jQuery and enhancing accessibility and SEO features.
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.
