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

Drei Austria holds a strong market position as a major telecommunications provider in Austria, leveraging a diversified business model that includes mobile, internet, TV, and energy services. Their revenue streams likely include subscription plans, device sales, and energy supply contracts. The company targets private consumers with tailored offers such as 'Handyfreiheit' device financing and green energy options, indicating a customer-centric approach. The presence of multiple social media channels and app store links suggests active engagement and digital marketing efforts. The company appears to be large and well-established, with consistent branding and a comprehensive service ecosystem.

Security posture

The website exhibits a mature security posture with HTTPS enforced and multiple security headers implemented, reducing risks of common web attacks. No sensitive data leaks or vulnerable libraries were detected in the HTML content. However, the absence of a publicly available security policy or incident response contact limits transparency. There is no evidence of a vulnerability disclosure program or security.txt file. Privacy policies and cookie consent mechanisms are well implemented, supporting GDPR compliance. Overall, the security maturity is high but could be improved by adding explicit security governance documentation and incident handling information.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and commitments.
  2. Provide clear incident response contact details such as security@ or abuse@ email addresses.
  3. Implement and publicize a vulnerability disclosure program or security.txt file.
  4. Regularly review and audit third-party scripts and libraries for vulnerabilities.
  5. Enhance accessibility features to meet or exceed compliance standards.

Technical notes

Notes

The website is built using Next.js, a modern React framework, and managed via Storyblok CMS, indicating a modern and scalable technical infrastructure. The site uses responsive images and preloading strategies to optimize performance. Security headers and HTTPS are properly configured, contributing to a secure environment. The presence of multiple asynchronous JavaScript chunks suggests modular code splitting for performance. While hosting provider details are not explicit, the use of advanced frameworks and CDN-hosted assets implies a robust hosting environment. Performance is moderate to fast, with excellent mobile optimization and good SEO practices. Opportunities exist to further improve accessibility and provide more detailed technical documentation.
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.
