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

WEMF AG für Werbemedienforschung is a well-established Swiss media research organization founded in 1964, providing independent and neutral auditing and research services for the media and advertising industry in Switzerland and Liechtenstein. Their offerings include media audits, comprehensive media studies, data solutions, and consulting services, positioning them as a trusted authority in their sector. The website reflects a professional and consistent brand image with good content quality and clear navigation. Technically, the site employs modern JavaScript libraries and tracking tools such as Google Tag Manager and Alpine.js, with a good security posture including HTTPS and security headers. However, the site lacks explicit privacy and cookie policies and consent mechanisms, which are critical for GDPR compliance. Overall, the site is secure, professional, and trustworthy but could improve transparency around privacy and incident response.

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

6 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 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';…

  2. 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

  3. 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

The company operates in the media sector, targeting media professionals, advertisers, and agencies in Switzerland and Liechtenstein. Their business model revolves around providing verified media data, audits, and research insights to support advertising decisions and media planning. The organization holds memberships in multiple international media research bodies, enhancing its credibility and market position. Their digital presence includes partnerships with related domains such as remp.ch and werbekompass.ch, indicating a collaborative ecosystem. The company is small-sized with about 24 employees, focusing on quality and specialized services rather than scale.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, presence of key security headers, and anonymization of IP addresses in analytics. No exposed sensitive data or vulnerable libraries were detected in the provided content. However, the absence of publicly available security policies, incident response contacts, and vulnerability disclosure mechanisms indicates room for improvement in transparency and readiness. The site uses third-party tracking scripts which should be regularly audited to mitigate supply chain risks. Overall, the security posture is good but could be enhanced by publishing formal security and privacy documentation.

Recommendations

  1. Publish a comprehensive privacy policy and cookie policy with GDPR-compliant consent mechanisms.
  2. Add a publicly accessible security policy and incident response contact information.
  3. Implement and publish a vulnerability disclosure policy and security.txt file.
  4. Enhance accessibility features to meet recognized standards.
  5. Regularly review and audit third-party scripts and tracking tools for security and privacy compliance.

Technical notes

Notes

The website uses a modern tech stack including Google Tag Manager, Google Analytics, Alpine.js, and autocomplete libraries, indicating a focus on user experience and analytics. The site is hosted likely on a Swiss provider (inferred), with good SSL configuration and security headers. Performance is moderate with room for optimization. SEO is well addressed with canonical tags, hreflang attributes, and structured data. Mobile optimization is good, though accessibility could be improved. No CMS was explicitly detected, suggesting a custom or proprietary solution. Overall, the technical infrastructure supports the business needs effectively but could benefit from enhanced accessibility and privacy features.
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.
