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

The website viennacitycard.at serves as the official platform for the Vienna City Card, a tourism product offering public transport access and discounts in Vienna. It is operated by WienTourismus and targets tourists seeking convenient mobility and sightseeing benefits. The site features a modern TYPO3 CMS infrastructure with Alpine.js for interactivity, hosted behind Cloudflare. While the site is content-rich, well-branded, and professionally designed with good mobile optimization and accessibility, it suffers from a critical security issue: the SSL certificate is invalid or missing, and no modern TLS protocols are enabled, which significantly impacts the security posture. Privacy compliance is strong, with a clear privacy policy, cookie consent via Usercentrics, and GDPR adherence. The site integrates Matomo analytics and Google Tag Manager for tracking, balanced with user privacy controls. Overall, the site is trustworthy and professional but requires urgent SSL/TLS remediation to ensure secure user interactions.

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

5 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 Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • 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

Vienna City Card is positioned as an essential tourism product in Vienna, offering multiple ticket durations and optional add-ons like airport transfer and hop-on hop-off tours. The business model is e-commerce focused, selling tickets and vouchers online and via apps. The company leverages partnerships with Vienna Sightseeing and environmental certification bodies to enhance credibility. The target audience includes international tourists, supported by multilingual content and app integration. The site’s ecosystem includes official apps and social media channels, reinforcing brand presence. Revenue streams are primarily ticket sales and optional service add-ons. The business shows maturity in digital marketing and customer engagement but should strengthen security to maintain customer trust.

Security posture

The website demonstrates moderate security maturity with several HTTP security headers implemented, including HSTS, X-XSS-Protection, and X-Content-Type-Options. However, the absence of a valid SSL certificate and disabled TLS protocols represent critical vulnerabilities that expose users to potential interception and downgrade attacks. The lack of DMARC DNS records weakens email security posture. No incident response or vulnerability disclosure policies are publicly available, indicating limited transparency in security governance. The site uses secure cookie flags and avoids known vulnerable libraries. Overall, the security posture is compromised by missing SSL/TLS, which should be prioritized to protect user data and maintain compliance.

Recommendations

  1. Obtain and deploy a valid SSL/TLS certificate immediately to enable HTTPS and protect user data.
  2. Enable and configure modern TLS protocols (TLS 1.2 and TLS 1.3) to ensure secure communications.
  3. Implement OCSP stapling to improve certificate validation performance and security.
  4. Add DMARC DNS records to enhance email authentication and reduce phishing risks.
  5. Publish a security policy and vulnerability disclosure program to improve transparency and incident response readiness.

Technical notes

Notes

The website is built on TYPO3 CMS with Alpine.js for frontend interactivity, hosted behind Cloudflare CDN. It uses Google Tag Manager and Matomo for analytics and Usercentrics for consent management, indicating a modern and privacy-aware tech stack. Performance is moderate with deferred JavaScript loading and preloading of fonts. The site is mobile-optimized and accessible with ARIA roles and keyboard navigation support. SEO is supported by meta tags, Open Graph, and hreflang attributes for multilingual support. However, the lack of a valid SSL certificate and disabled TLS protocols represent significant technical debt and risk. The DNS setup is standard with Cloudflare nameservers and SPF records configured, but no DNSSEC or CAA records are present. Overall, the technical infrastructure is solid but requires urgent security upgrades.
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.
