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. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  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

      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';…

  3. GDPR outside view

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

    • 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

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

Carte Blanche serves as a loyalty program enhancing subscriber retention and engagement for Tamedia AG. Its business model leverages exclusive offers and contests to add value to media subscriptions, targeting culturally engaged Swiss consumers. The platform integrates with Tamedia's digital subscription services and help center, indicating a mature ecosystem. The presence of multiple regional offers and partnerships suggests a broad market reach within Switzerland. The company benefits from Tamedia's strong market position and brand recognition, supporting sustainable growth and customer loyalty.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, standard security headers, and secure form handling including CAPTCHA. However, it lacks publicly available security policies or incident response contacts, which could improve transparency and readiness. No vulnerabilities or exposed sensitive data were detected in the analysis. The use of multiple third-party scripts requires ongoing vigilance to mitigate supply chain risks. GDPR compliance is evident through privacy and cookie policies with consent management. Overall, the security posture is good but could be enhanced by publishing more explicit security governance information.

Recommendations

  1. Publish a dedicated security policy and incident response information page.
  2. Implement and publish a vulnerability disclosure policy or security.txt file.
  3. Enhance accessibility features to meet higher compliance standards.
  4. Regularly audit and update third-party scripts to minimize security risks.
  5. Provide contact details for the Data Protection Officer to improve GDPR transparency.

Technical notes

Notes

The website is built on a modern React/Next.js stack with server-side rendering capabilities, ensuring good performance and SEO. It uses UnityCMS for content management and integrates multiple advertising and analytics services including Google Tag Manager, DoubleClick, and Permutive. The site is mobile-optimized and uses lazy loading for images to improve load times. Security headers and HTTPS are properly configured. Some performance optimization opportunities exist, but overall the technical infrastructure is robust and supports a professional media loyalty platform.
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.
