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

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 operates within the real estate and government sectors, focusing on social housing in Vienna. It leverages partnerships with related service providers such as wohnberatung-wien.at and mieterhilfe.at to extend its service offerings. The business model is service-oriented, funded likely through public means, aiming to support residents with housing needs and legal tenant advice. The presence of a newsletter and detailed service links indicates active engagement with its audience. The site’s market position is strong locally, supported by consistent branding and official contact details. Growth indicators include ongoing campaigns and updates about housing projects. The partnership ecosystem is well integrated, enhancing service delivery and community outreach.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and use of hCaptcha to mitigate spam and abuse on forms. Cookie consent is implemented with granular categories, aligning with GDPR requirements. However, the absence of security headers such as Content-Security-Policy and lack of published security or incident response policies represent areas for improvement. No vulnerabilities or exposed sensitive data were detected in the HTML content. The site does not publish a vulnerability disclosure policy or security.txt file, which could enhance transparency and trust. Overall, the security measures are adequate for a public service website but could be strengthened to meet higher standards.

Recommendations

  1. Implement HTTP security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Publish a dedicated security policy page and provide clear incident response contact information to improve transparency and user trust.
  3. Consider adding a vulnerability disclosure policy or security.txt file to encourage responsible reporting of security issues.
  4. Regularly review and update third-party libraries and CMS components to mitigate potential vulnerabilities.
  5. Enhance monitoring and logging capabilities to detect and respond to security incidents promptly.

Notes

The website is built on TYPO3 CMS, a robust and widely used content management system, combined with Bootstrap for responsive design. It integrates hCaptcha for bot protection and Piwik (Matomo) for privacy-focused analytics. The site is mobile optimized with good accessibility features and SEO practices, including proper meta tags and structured navigation. Performance is moderate, with compressed CSS and JS assets loaded. No major technical debt or outdated technologies were detected. Opportunities exist to improve security headers and possibly enhance hosting provider transparency. Overall, the technical infrastructure supports a stable and user-friendly experience aligned with the site's public service mission.
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.
