Risk levelLow

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

The Burgtheater website represents a well-established cultural institution in Austria, offering a comprehensive program of theatrical performances, educational offerings, and subscription services. The site targets theatergoers, educational institutions, and cultural enthusiasts, positioning itself as a key player in Vienna's cultural landscape. Technically, the website is built on Drupal with Bootstrap theming and uses modern JavaScript libraries such as Swiper for carousels and Matomo for analytics, indicating a moderate level of digital maturity. The site is mobile-optimized and accessible, with a professional design and clear navigation. However, there are notable gaps in privacy and security compliance, including the absence of visible privacy and cookie policies, lack of security headers, and no incident response contacts, which could expose the organization to compliance risks and reduce user trust. Overall, the domain registration data aligns well with the website's claims, supporting its legitimacy. Strategic improvements in privacy compliance and security posture are recommended to enhance trust and regulatory adherence.

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

Burgtheater operates as a cultural institution with a focus on theatrical arts, offering ticket sales, subscriptions, and educational programs. Its market position is strong within Vienna's cultural sector, supported by a rich history and a diverse ensemble. The business model relies on audience engagement through performances and memberships. The website's integration with social media platforms enhances its outreach and audience interaction. There is no evidence of parent or subsidiary companies, indicating independent operation. The organization's digital presence is professional but could benefit from enhanced transparency in privacy and security policies to meet evolving regulatory standards and audience expectations.

Security posture

The current security posture of the Burgtheater website is moderate but has room for improvement. While HTTPS is presumably enabled (not explicitly confirmed in the data), there is no evidence of critical security headers such as Content-Security-Policy or X-Frame-Options, which are essential for mitigating common web vulnerabilities. The absence of visible privacy and cookie policies suggests potential GDPR compliance gaps. No dedicated security or incident response contact information is provided, which is a best practice for handling security incidents. The use of Matomo and Clickskeks for analytics indicates user tracking, but without clear privacy disclosures, this could pose compliance risks. Enhancing security headers, publishing comprehensive privacy and cookie policies, and providing incident response contacts would significantly strengthen the security posture.

Recommendations

  1. Publish comprehensive privacy and cookie policies prominently on the website to ensure GDPR compliance.
  2. Implement and configure essential security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Provide clear contact information for security incidents, including dedicated email addresses like security@ or abuse@.
  4. Conduct a security audit to identify and remediate any vulnerable libraries or exposed sensitive data.
  5. Enhance transparency about data collection and retention practices related to analytics and tracking tools.

Technical notes

Notes

The website is built on Drupal CMS with a Bootstrap-based theme, leveraging modern JavaScript libraries like Swiper for interactive carousels and Matomo for analytics tracking. The site uses SVG icons extensively for UI elements, contributing to a scalable and visually consistent design. Performance appears moderate, with responsive images and video content optimized for different screen sizes. Accessibility features such as skip links and ARIA labels are present, indicating attention to inclusive design. However, the lack of visible security headers and privacy disclosures points to technical debt in compliance and security best practices. Hosting details are not explicitly identified, and no CDN or cloud provider information is available from the provided data.
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.
