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

Zambelli Holding GmbH is a medium-sized manufacturing company based in Germany specializing in metal system solutions across multiple sectors including roof drainage, building envelopes, shelving systems, caravaning, heating technology, and industrial metalworking. The company maintains a professional and well-structured website that targets business customers and industry professionals, showcasing its diverse product and service offerings. The website demonstrates consistent branding and good content quality, supporting the company's established market position. Technically, the website is built on modern web standards with responsive design, leveraging technologies such as HTML5, CSS3, JavaScript, and Adobe Typekit fonts. The CMS identified is Contao, which supports structured content management. Performance and mobile optimization are good, though accessibility features could be enhanced. SEO practices are adequately implemented with proper meta tags and structured data. From a security perspective, the site uses HTTPS with a good SSL configuration and no visible vulnerabilities or exposed sensitive data. However, security headers are not explicitly detected, and there is no visible cookie consent mechanism, which could impact GDPR compliance. The absence of WHOIS data for the domain is a notable anomaly that slightly reduces trustworthiness, though the website content and business information appear legitimate. Overall, the website presents a professional and trustworthy digital presence for Zambelli Holding GmbH, with recommendations to improve privacy compliance and security headers to enhance user trust and regulatory adherence.

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

7 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. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • 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

    • High

      Third-party services without privacy policy

      Detected services: Facebook, LinkedIn

      What to do: Document all third-party data sharing in your privacy policy

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

Zambelli Holding GmbH operates in the manufacturing sector with a diversified portfolio of metal system solutions. Its market positioning is that of an established manufacturer with multiple business divisions and an international footprint, including locations in Germany, Czech Republic, Hungary, and Romania. The company targets B2B customers in construction, industrial metalworking, and caravaning sectors. Revenue streams likely derive from product sales, engineering services, and after-sales support. The presence of a whistleblower channel and detailed privacy and terms pages indicate a mature compliance posture. The company leverages social media channels for brand presence and customer engagement. The lack of WHOIS data is unusual and should be monitored for potential risks.

Security posture

The website demonstrates a solid security posture with HTTPS enforced and no visible exposure of sensitive data. However, the absence of key security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options suggests room for improvement. No incident response or security policy pages were found, and no dedicated security contact channels are provided. The lack of a cookie consent mechanism may pose GDPR compliance risks. Overall, the security maturity is moderate to good, with recommendations to implement additional headers, publish security policies, and enhance privacy controls to strengthen defenses and compliance.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web attacks.
  2. Deploy a cookie consent banner/mechanism to ensure GDPR compliance and inform users about data collection.
  3. Publish explicit security policy and incident response contact information to improve transparency and readiness.
  4. Regularly audit and update third-party scripts and libraries to avoid vulnerabilities.
  5. Enhance website accessibility features to improve usability for all users and comply with accessibility standards.

Technical notes

Notes

The website uses a modern technology stack with HTML5, CSS3, JavaScript, and Adobe Typekit fonts for typography. The CMS identified is Contao, which supports structured content and multilingual capabilities. The site includes responsive design elements and a slick slider for dynamic content presentation. Performance is moderate with asynchronous script loading. SEO is supported by proper meta tags, canonical links, and structured JSON-LD data. However, there is no explicit hosting provider information detected. Accessibility is basic and could be improved with ARIA roles and better keyboard navigation support. Overall, the technical implementation is solid but could benefit from enhanced security 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.
