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

8 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

  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

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

Hauskunft holds a strong market position as a trusted government-backed advisory service focused on sustainable building renovations and energy transition in Vienna. Its business model is non-profit, funded by the city, and aims to facilitate energy-efficient upgrades through expert advice and promotion of subsidies. The service has demonstrated growth with over 18,000 consultations and 1,500 initiated projects since 2020. Partnerships with the City of Vienna, klimaaktiv-gebaut.at, and local energy initiatives enhance its ecosystem. The website supports customer engagement via newsletters, events, and training for property managers, indicating a comprehensive outreach strategy. The clear branding and consistent messaging reinforce its credibility and public trust.

Security posture

The website exhibits a solid security maturity level with enforced HTTPS, presence of key security headers (HSTS, CSP, X-Frame-Options, X-Content-Type-Options), and secure handling of user input via forms with mandatory consent checkboxes. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of explicit incident response contacts and vulnerability disclosure mechanisms represents a minor compliance gap. The use of Matomo analytics aligns with privacy-conscious practices. Overall, the security posture is robust for a public-facing government service, minimizing risks related to data breaches or misuse.

Recommendations

  1. Publish explicit incident response contact information and procedures on the website.
  2. Implement and publicize a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  3. Consider appointing and listing a Data Protection Officer contact to enhance GDPR compliance transparency.
  4. Maintain regular security audits and update third-party libraries to mitigate emerging vulnerabilities.
  5. Enhance user awareness about data retention policies and cookie usage for improved privacy transparency.

Technical notes

Notes

The website employs a modern and clean technical infrastructure with responsive design, SVG-based logos, and interactive carousels powered by Swiper.js. It uses Matomo for analytics, which respects user privacy better than many alternatives. The site is well optimized for mobile devices and accessibility, with semantic HTML and ARIA attributes. Performance is moderate, likely due to rich media content but remains user-friendly. No CMS was explicitly detected, suggesting a custom or proprietary platform. Hosting details are not disclosed. The technical setup supports a professional and secure user experience, though opportunities exist to enhance incident response and vulnerability management 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.
