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.

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

Business profile

Zühlke operates in multiple regulated and complex sectors including technology, healthcare, finance, transportation, and government. Their business model focuses on consulting, engineering, and delivery of technology-driven solutions that enable clients to innovate and transform their operations. The company targets enterprise clients seeking to leverage AI, cloud, and digital strategies to gain competitive advantage. Their extensive service offerings and cross-industry expertise position them as a holistic transformation partner. The presence of detailed case studies and insights indicates a strong content marketing strategy supporting lead generation and thought leadership. Social media engagement on LinkedIn, Xing, and Facebook further supports their market positioning. The lack of public WHOIS data suggests privacy protection or alternative domain registration practices, which is not uncommon for large enterprises but warrants verification.

Security posture

The website enforces HTTPS and uses cookie consent tools, indicating compliance with privacy regulations such as GDPR. Security headers are not explicitly detected in the provided data, and no dedicated security or incident response pages are found, which could be improved. No vulnerabilities or exposed sensitive data were identified in the HTML content. The use of reputable third-party scripts and analytics tools is noted, but continuous monitoring for vulnerabilities in these dependencies is recommended. The absence of a security.txt or vulnerability disclosure policy limits transparency for security researchers. Overall, the security posture is good but could benefit from enhanced public security documentation and HTTP header hardening.

Recommendations

  1. Publish a dedicated security policy and incident response page to improve transparency and trust.
  2. Implement and expose a vulnerability disclosure program or security.txt file to facilitate responsible reporting.
  3. Enhance HTTP security headers such as Content-Security-Policy, Strict-Transport-Security, X-Frame-Options, and X-Content-Type-Options.
  4. Regularly audit and update third-party scripts and libraries to mitigate potential vulnerabilities.
  5. Provide explicit contact information for data protection officers or security teams to comply with GDPR and improve incident handling.

Technical notes

Notes

The website is built on Drupal 10 CMS, leveraging modern JavaScript libraries including jQuery, Plyr for media, GSAP for animations, and Rellax for parallax effects. It integrates marketing and analytics tools such as Microsoft Dynamics 365 and Plausible Analytics, indicating a mature digital marketing infrastructure. The site is optimized for mobile devices and accessibility, with good SEO practices including meta tags and structured data (JSON-LD). Performance is fast with preloading of fonts and scripts. The technical stack is modern and well-maintained, supporting a professional and engaging user experience. Opportunities exist to improve security headers and public security documentation to reduce technical risks.
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.
