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

2 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.

    • 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

  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

  • Security headers: did not complete in this scan.
  • 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

Tamedia AG holds a leading position in the Swiss media market, leveraging its long history and trusted brand to attract subscribers and advertisers. The website integrates multiple digital services including e-paper, newsletters, and podcasts, enhancing user engagement. Partnerships with advertising networks and service providers like Goldbach and Piano support monetization and user management. The company targets general news consumers in Switzerland, with a focus on regional content for areas like Zürcher Unterland. The business shows maturity with a diversified content offering and strong digital infrastructure.

Security posture

The website demonstrates a solid security posture with HTTPS enforcement, comprehensive security headers, and consent management via OneTrust. Forms are protected with Turnstile Captcha to mitigate abuse. However, no explicit security policy or incident response contact is published, which could be improved to enhance transparency and readiness. The integration of multiple third-party scripts requires ongoing monitoring to prevent vulnerabilities. Overall, the security measures align well with industry best practices for media websites.

Recommendations

  1. Publish a dedicated security policy and incident response page to improve transparency and user trust.
  2. Implement and publicize a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  3. Regularly audit and update third-party scripts and libraries to mitigate potential security risks.
  4. Enhance data retention policy disclosures to comply fully with GDPR and user expectations.
  5. Continue improving accessibility and SEO to maintain competitive digital presence.

The website is built on a modern React-based framework (Next.js) with server-side rendering, ensuring good performance and SEO. It uses UnityCMS for content management and integrates advanced advertising and analytics technologies such as Prebid.js, Google Tag Manager, and Permutive. Hosting appears to be provided by Hetzner Online, a reputable provider. The site is mobile-optimized with responsive design and accessibility features. Performance is moderate, with room for optimization in script loading and caching strategies. The technical stack supports scalability and rich user experience.
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.
