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 government and non-profit sectors, focusing on tenant rights and housing law advisory services in Vienna. Its business model is service-oriented, funded likely by municipal or public funds, offering free consultations and legal aid. The platform's market position is strong within its niche, supported by partnerships with related housing services and city agencies. The presence of multiple language options and comprehensive tools indicates a user-centric approach targeting diverse tenant demographics. The site’s branding and content quality reinforce its credibility and trustworthiness. No commercial or revenue-generating activities like advertising or affiliate marketing are evident, aligning with its public service mission.

Security posture

MieterHilfe.at exhibits a mature security posture with enforced HTTPS, use of hCaptcha to protect forms from automated abuse, and a cookie consent banner compliant with GDPR. The site uses Matomo analytics, which respects user privacy better than many alternatives. However, the absence of published security policies, incident response contacts, and advanced security headers (e.g., CSP, X-Frame-Options) suggests room for improvement in transparency and defense-in-depth. No vulnerabilities or exposed sensitive data were detected in the content. Overall, the site maintains a secure environment appropriate for a public advisory service but should enhance its security documentation and headers to strengthen trust and resilience.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and user data protection.
  2. Add incident response contact information such as security@ or abuse@ email addresses.
  3. Implement and configure security headers like Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  4. Regularly review and update third-party scripts and dependencies to mitigate vulnerabilities.
  5. Enhance transparency by providing terms of service and data retention policies.

Technical notes

Notes

The website is built on TYPO3 CMS with Bootstrap framework, ensuring a modern and responsive design. It integrates hCaptcha for bot protection and Matomo for privacy-focused analytics. The site loads a compressed and merged CSS and JS asset bundle, indicating optimization efforts. The presence of canonical tags and meta descriptions supports SEO. Accessibility features such as skip links and ARIA attributes are implemented, enhancing usability. Performance is moderate, with room for improvement in hosting and asset delivery. The technical stack is stable and appropriate for a government/non-profit service website, with opportunities to improve security headers and incident response readiness.
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.
