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. 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 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';…

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

  3. 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
    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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 business is positioned as a multi-brand automotive dealer with a focus on customer service and comprehensive offerings including new and used cars, financing, and after-sales services. The integration with partner platforms like dasweltauto.at and sbo.porscheinformatik.com indicates a strategic ecosystem approach to vehicle sales and service bookings. The company targets local and regional customers in Austria, leveraging brand trust and customer reviews to maintain a competitive advantage. The business model is traditional dealership supplemented by digital tools for customer engagement and service management.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, presence of key security headers, and use of a reputable cookie consent management system (OneTrust). No sensitive data leakage or vulnerable libraries were detected in the HTML content. However, the absence of published security policies, incident response contacts, and vulnerability disclosure mechanisms represents a compliance and transparency gap. The site would benefit from publishing these documents to enhance trust and readiness for security incidents. Overall, the security posture is good but can be improved with formalized policies and disclosures.

Recommendations

  1. Publish a comprehensive privacy policy and ensure it is easily accessible from all pages.
  2. Add terms of service to clarify user and customer agreements.
  3. Develop and publish a security policy and incident response plan with clear contact channels.
  4. Implement a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  5. Enhance accessibility features to meet WCAG standards and improve user inclusivity.

Technical notes

Notes

The website is built on the Plone CMS, a robust and secure content management system. It uses modern front-end libraries such as Swiper.js for sliders and Select2 for enhanced select inputs. Google Tag Manager is used for analytics and marketing tracking, and OneTrust manages cookie consent, indicating compliance efforts. The site loads external resources securely via HTTPS and uses responsive design techniques for mobile optimization. Performance is moderate, with room for optimization in image loading and script management. No critical technical debt or outdated technologies were detected, but continuous monitoring of third-party scripts is recommended to mitigate supply chain risks.
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.
