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

No critical or high findings. These medium findings are worth fixing next.

  1. GDPR outside view

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

    • Medium

      Privacy policy may not be GDPR compliant

      Privacy policy lacks explicit GDPR compliance elements

      What to do: Update privacy policy to explicitly address GDPR requirements and user rights

  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.

  3. DNS health

    DNS sends visitors and email to the right servers. Misconfigured records can cause outages or let someone redirect your traffic.

    • Medium

      DNSSEC Not Enabled

      DNSSEC is not configured for this domain

      What to do: Enable DNSSEC to prevent DNS spoofing attacks

      • CAPEC-142
      • RFC 4033
      • RFC 4035
    • Medium

      Domain Transfer Lock Not Enabled

      Domain can be transferred without authorization

      What to do: Enable domain transfer lock for security

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

Ziggo holds a significant market position in the Netherlands telecommunications sector, targeting both consumers and businesses. Its business model centers on bundled telecommunications services, enhanced by partnerships with Vodafone and other brands. The company leverages a comprehensive digital ecosystem including e-commerce, customer portals, and loyalty programs. Growth is supported by cross-selling mobile services and premium content offerings. The partnership ecosystem includes Vodafone, hollandsnieuwe, and Priority rewards, indicating a strong integrated service approach.

Security posture

The website demonstrates a solid security foundation with HTTPS, CSRF token endpoints, and cookie consent via OneTrust. However, the absence of publicly accessible security policies, incident response contacts, and vulnerability disclosure mechanisms suggests room for improvement in transparency and readiness. No critical vulnerabilities or exposed sensitive data were detected. Security headers appear partially implemented, and regular audits of third-party scripts are recommended to maintain security hygiene.

Recommendations

  1. Publish a clear privacy policy and terms of service accessible from the homepage.
  2. Add a public security policy and incident response contact information.
  3. Implement and publish a vulnerability disclosure policy or security.txt file.
  4. Ensure all recommended security headers are present and properly configured.
  5. Regularly audit third-party scripts and tracking tools for security and privacy compliance.

Technical notes

Notes

The website uses a modern tech stack including Vue.js and Adobe Experience Manager, hosted on AWS infrastructure. Performance is moderate with good mobile optimization and accessibility features. SEO is well addressed with proper meta tags and Open Graph data. The site uses advanced analytics and marketing tools such as Google Analytics, Google Tag Manager, Optimizely, and OneTrust for cookie management. Technical debt appears low, but continuous monitoring and updates are advised to maintain performance and security.
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.
