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

co2-auto.at is an Austrian-focused online platform operated by co2.auto GmbH Niederlassung Österreich that facilitates the registration and sale of CO2 emission reduction quotas (THG-Quote) for electric vehicle owners and charging station operators. The platform enables users to register their electric vehicles, upload required documents, and receive an annual ePrämie (bonus) by bundling and submitting eQuoten to the Austrian Umweltbundesamt. The website is well-structured, informative, and targets electric vehicle owners in Austria, providing clear guidance and support for quota trading. Technically, the site uses standard web technologies with good mobile optimization and SEO practices but lacks explicit CMS or advanced frameworks. Security posture is solid with HTTPS and encrypted session management, though security headers and incident response policies are not explicitly published. Privacy compliance is strong with a comprehensive privacy policy and cookie consent mechanism. Overall, the site is trustworthy, professional, and serves a niche market in the energy and transportation sectors.

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

3 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • 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';…

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 company positions itself as a key facilitator in the emerging Austrian THG-Quote market, leveraging regulatory frameworks to provide value to electric vehicle owners and charging station operators. Its business model is based on aggregating eQuoten and monetizing them through official certification and trading processes. The platform targets private individuals and businesses with electric vehicles, including fleet operators. The presence of a sister domain for the German market indicates a regional expansion strategy. The company benefits from regulatory trust and clear legal compliance, with growth potential as electric mobility adoption increases. Partnerships with regulatory bodies and transparent operations enhance credibility.

Security posture

The website demonstrates a moderate to good security posture with enforced HTTPS, encrypted session identifiers, and a cookie consent mechanism. However, it lacks visible security headers such as Content-Security-Policy or X-Frame-Options, and no public security policy or incident response contacts are provided. There is no evidence of vulnerability disclosures or security.txt files. Data protection practices appear adequate, with data usage limited to regulatory submissions and no third-party data sharing beyond necessary analytics and marketing services. Overall, the security maturity is acceptable for the business type but could be improved with additional transparency and technical controls.

Recommendations

  1. Implement and publish security headers (CSP, X-Frame-Options, X-Content-Type-Options) to enhance protection against common web attacks.
  2. Publish a formal security policy and provide incident response contact information to improve transparency and trust.
  3. Consider adding a vulnerability disclosure program or security.txt file to encourage responsible reporting of security issues.
  4. Enhance accessibility features to improve usability for all users, including those with disabilities.
  5. Regularly review and update privacy and cookie policies to maintain compliance with evolving GDPR and ePrivacy regulations.

Technical notes

Notes

The website is built with standard HTML5, CSS3, and JavaScript, including jQuery. No major CMS or advanced frameworks are detected, suggesting a custom or lightweight platform. The site is mobile-optimized with responsive design and includes SEO best practices such as meta tags and structured data (JSON-LD). Performance is moderate, with no explicit hosting provider identified. Cookie consent and analytics integration with Google services are implemented. There is room for technical modernization, including adoption of modern JavaScript frameworks, improved accessibility, and enhanced security headers.
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.
