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

2 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.

    • 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. 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

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 Burgtheater operates as a cultural and hospitality entity with a business model centered on ticket sales, subscriptions, and educational offerings. It maintains a strong social media presence across Instagram, Facebook, TikTok, and YouTube, enhancing audience engagement. The partnership with tickets.burgtheater.at for ticketing services indicates a well-structured operational ecosystem. The institution likely benefits from public funding and private sponsorships, typical for large cultural organizations. Its market position is solidified by its historical significance and comprehensive programming. Growth opportunities may include expanding digital engagement and enhancing online ticketing experiences.

Security posture

The website exhibits a mature security posture with enforced HTTPS, presence of key security headers, and secure handling of user inputs in forms. No exposed sensitive data or vulnerable libraries were detected. However, the absence of a public security policy or incident response contact limits transparency in security governance. The site could improve by publishing a security.txt file and enhancing incident response visibility. Privacy practices align with GDPR requirements, supported by a dedicated data protection officer contact. Overall, the security maturity is good with room for formalizing policies and disclosure mechanisms.

Recommendations

  1. Publish a dedicated security policy and incident response contact information on the website.
  2. Implement and publish a security.txt file to facilitate vulnerability disclosure.
  3. Regularly audit and update third-party scripts and tracking tools to mitigate vulnerabilities.
  4. Enhance transparency around data retention policies and user privacy controls.
  5. Maintain and improve accessibility and SEO best practices to broaden audience reach.

Technical notes

Notes

The website is built on Drupal CMS with a Bootstrap-based theme, ensuring responsive design and accessibility. It integrates Matomo for analytics and Clickskeks for marketing and tracking. The site uses modern HTML5 video elements and SVG icons for performance and scalability. Performance is moderate, with potential optimization in media delivery and script loading. The hosting provider is not explicitly identified. SEO is supported by canonical links, Open Graph tags, and structured navigation. Accessibility features such as skip links and ARIA labels are implemented, contributing to a good user experience. Technical risks are minimal but should be monitored through regular updates and security assessments.
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.
