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

3 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 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. 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
    • High

      Weak SSL Key Length

      SSL certificate uses 384-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

Kommuniversum AG positions itself as a creative and flexible advertising partner in the Swiss market, targeting businesses and organizations seeking impactful marketing solutions. Its business model focuses on delivering tailored advertising campaigns supported by strategic consulting and content services. The agency leverages its parent company Linkgroup AG for extended capabilities, enhancing its service offerings. The presence of notable clients and positive testimonials indicates a solid reputation and competitive advantage in the local market. The company maintains a professional online presence with GDPR-compliant privacy and cookie policies, supporting trust and regulatory adherence. Growth potential is supported by its network and agile operational structure.

Security posture

The website demonstrates a moderate to good security posture with HTTPS enforced and spam-protected email addresses implemented via JavaScript obfuscation. Cookie consent is actively managed, indicating awareness of privacy regulations. However, the absence of explicit security headers such as Content-Security-Policy and lack of published security or incident response policies represent areas for improvement. No vulnerabilities or exposed sensitive data were detected in the analysis. The use of third-party scripts like Google Tag Manager is standard but should be regularly audited to mitigate risks. Overall, the security maturity is adequate for the business type but could be enhanced by adopting additional best practices and transparency measures.

Recommendations

  1. Implement and configure security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Publish a clear security policy and provide dedicated incident response contact channels to improve transparency and readiness.
  3. Regularly review and update third-party scripts and libraries to avoid vulnerabilities.
  4. Enhance accessibility features to improve compliance and user experience for all visitors.
  5. Maintain and document data retention policies related to analytics and user data to strengthen privacy compliance.

Notes

The website is built on TYPO3 CMS, a robust and widely used content management system, supported by jQuery and Google Tag Manager for analytics and tracking. The site uses responsive design techniques and optimized images for good mobile performance. While the performance is moderate, there is room for improvement in loading speed and accessibility compliance. The technical implementation includes modern meta tags for SEO and social sharing, contributing to good search engine visibility. No critical technical debt or outdated technologies were identified, indicating a well-maintained infrastructure. Hosting details are not explicitly available, but the presence of HTTPS and external scripts suggests a professionally managed environment.
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.
