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

The website wienwohntbesser.at is an official government platform operated by the City of Vienna (Stadt Wien) focused on providing information and updates about municipal housing initiatives, campaigns, and services. It serves residents and housing seekers in Vienna, offering news, event details, and service area information related to affordable and livable housing. The site is well-branded with consistent city imagery and messaging, reinforcing its authoritative position in the local housing sector. Technically, the website is built on TYPO3 CMS with Bootstrap for responsive design, ensuring good mobile optimization and accessibility. It employs Piwik analytics with a GDPR-compliant cookie consent mechanism, reflecting a mature approach to privacy and user tracking. Performance is moderate, with no critical technical issues detected. However, security headers are not explicitly visible, and no dedicated security or incident response policies are published. From a security perspective, the site uses HTTPS and has implemented cookie consent controls, but lacks visible advanced security headers and formal vulnerability disclosure mechanisms. No exposed sensitive data or vulnerable libraries were detected. The WHOIS data confirms the domain is legitimately registered to the City of Vienna, aligning with the website's governmental nature and enhancing trustworthiness. Overall, the website presents a professional, secure, and privacy-conscious platform suitable for its public service role. Strategic improvements could include publishing explicit security policies, enhancing security headers, and providing clearer contact information for incident response. These steps would further strengthen the site's security posture and user trust.

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

4 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. 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 website represents a government entity focused on housing in Vienna, positioning itself as the primary information source for municipal housing projects and services. Its business model is public service and information dissemination, targeting residents and housing seekers. The platform leverages official branding and partnerships with related city services (wohnservice-wien.at). The use of TYPO3 CMS and Piwik analytics indicates a preference for open-source and privacy-respecting technologies. The absence of commercial advertising or affiliate programs aligns with its government mandate. Growth indicators include active news updates and campaigns promoting housing initiatives. The partnership ecosystem is primarily internal to city services, with no commercial partners detected.

Security posture

The website demonstrates a solid baseline security posture with HTTPS enforced and a GDPR-compliant cookie consent mechanism. No critical vulnerabilities or exposed sensitive data were found in the HTML content. However, the absence of explicit security headers (e.g., Content-Security-Policy, X-Frame-Options) and lack of published security policies or incident response contacts indicate room for improvement. The use of Piwik analytics is privacy-conscious but requires ongoing monitoring to ensure compliance. The WHOIS data legitimacy supports trust in the domain. Overall, the site is secure for its informational purpose but would benefit from enhanced security best practices and transparency.

Recommendations

  1. Implement and configure security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  2. Publish a dedicated security policy page and provide incident response contact information (e.g., security@ or abuse@ email).
  3. Consider adding a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Enhance visibility of contact information for user support and security concerns.
  5. Regularly audit third-party scripts and analytics tools to maintain privacy compliance and reduce tracking risks.

Technical notes

Notes

The website is built on TYPO3 CMS with the Bootstrap package, providing a modern, responsive design framework. It uses compressed CSS and JavaScript assets for performance optimization. The inclusion of Piwik analytics demonstrates a commitment to privacy-friendly tracking. The site is mobile-optimized and accessible, with skip links and ARIA attributes present. No broken links or errors were detected in the provided content. Hosting details are not explicitly available, but the domain is secured with HTTPS. The technical stack is mature and appropriate for a government informational site, with opportunities to enhance security headers and incident response capabilities.
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.
