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

Linkstudio operates as a specialized media production service provider within the Swiss market, leveraging its parent company Linkgroup AG's reputation. Its business model centers on delivering creative video and audio content for corporate clients, enhancing brand visibility and communication. The company benefits from a consistent branding strategy and offers multiple key services including videoproduction, motion design, and podcasts. The presence of testimonials and a detailed contact form supports client engagement and trust. The partnership ecosystem includes related domains like kommuniversum.ch, indicating collaborative projects. The company appears to be small-sized but well-positioned in the media sector with growth potential through digital channels.

Security posture

The website demonstrates a good security baseline with enforced HTTPS, obfuscated email addresses to reduce spam, and a cookie consent mechanism aligned with GDPR requirements. However, it lacks published security policies, incident response contacts, or vulnerability disclosure information, which are important for transparency and readiness. No security headers were detected in the provided data, suggesting an area for improvement. The absence of known vulnerabilities or exposed sensitive data is positive. Overall, the security maturity is moderate to good but could be enhanced by formalizing security governance and communication.

Recommendations

  1. Implement and publish a formal security policy and incident response plan on the website.
  2. Add security headers such as Content Security Policy (CSP), X-Frame-Options, and HSTS to improve protection against common web attacks.
  3. Create and publish a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Enhance accessibility features to improve compliance and user experience for all users.
  5. Regularly audit third-party scripts and libraries to ensure no vulnerabilities are introduced.

Technical notes

Notes

The website is built on TYPO3 CMS, a robust and widely used content management system, supported by JavaScript libraries like jQuery, Slick Carousel, and Magnific Popup for interactive features. Google Tag Manager is used for analytics integration, indicating a modern approach to data collection and marketing. The site is mobile-optimized with responsive images and layouts. Performance is moderate, with room for optimization in loading speed and accessibility. The technical stack is current and well-maintained, but the lack of security headers and explicit hosting information suggests potential areas for infrastructure improvement.
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.
