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

Divadlo Astorka Korzo '90 is a Slovak theatre company offering unique theatrical productions with a rich history. The website serves as a portal for program information, ticket sales, and contact details, targeting theatre enthusiasts and the general public in Slovakia. The business operates primarily in the hospitality and cultural sector, focusing on live performances and audience engagement. Technically, the website is built on modern frameworks such as React and Next.js, with Material UI for styling, providing a responsive and user-friendly experience. However, performance is moderate and accessibility features are basic, indicating room for improvement. Security posture is adequate with HTTPS enabled but lacks advanced security headers and incident response contacts, which could enhance trust and protection. Privacy compliance is addressed with visible privacy and cookie policies, though a consent mechanism is absent. Overall, the website is professional and trustworthy but could benefit from enhanced security and privacy features to align with best practices.

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

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

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 theatre holds a stable market position in Bratislava, Slovakia, serving a niche audience interested in cultural and theatrical events. Its business model revolves around live performances and online ticket sales, supported by clear contact channels and social media presence. The company demonstrates consistent branding and provides essential legal and privacy documentation, indicating operational maturity. Growth potential exists through improved digital marketing and enhanced user engagement features. Partnerships with ticketing platforms like entradio.sk are evident, supporting streamlined ticket sales. The absence of detailed financial or corporate structure data limits deeper business intelligence insights.

Security posture

The website maintains a basic security posture with HTTPS enabled, ensuring encrypted communications. However, the absence of key security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security reduces defense-in-depth. No dedicated security or incident response contact information is provided, which may hinder timely vulnerability reporting and mitigation. The site does not expose sensitive data or show signs of vulnerabilities in the analyzed content. Privacy policies are present but lack explicit cookie consent mechanisms, which is a compliance gap under GDPR. Overall, the security maturity is moderate but can be significantly improved with standard best practices and incident response readiness.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to enhance protection against common web attacks.
  2. Add a cookie consent banner or mechanism to comply fully with GDPR and improve user privacy transparency.
  3. Establish and publish a dedicated security policy and incident response contact (e.g., security@ or abuse@ email) to facilitate vulnerability reporting and response.
  4. Enhance accessibility features to meet recognized standards, improving usability for all users and compliance with legal requirements.
  5. Conduct regular security audits and dependency checks to identify and remediate potential vulnerabilities in third-party libraries and scripts.

Technical notes

Notes

The website leverages a modern React and Next.js framework combined with Material UI for styling, indicating a contemporary and maintainable tech stack. The site is mobile optimized with responsive design elements, though performance is moderate, suggesting potential optimization opportunities. SEO is basic with proper meta tags and Open Graph data but could be improved with structured data like JSON-LD for enhanced search visibility. No CMS or hosting provider details are explicitly detected. The absence of analytics or tracking scripts suggests minimal user tracking, aligning with privacy-conscious practices but limiting marketing insights. Overall, the technical infrastructure is solid but could benefit from performance tuning and enhanced SEO and accessibility implementations.
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.
