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

METALLART Treppen GmbH is a specialized manufacturer of exclusive, high-quality sculptural staircases with a heritage of over 100 years. The company serves a global clientele including architects, builders, and private clients, offering custom design, manufacturing, and consulting services. Their market position is strong within the manufacturing sector for architectural staircases, supported by a professional website showcasing extensive project portfolios and client testimonials. Technically, the website is built on modern frameworks such as Astro and Alpine.js, hosted likely on Netlify, and incorporates privacy and analytics tools like Cookiebot and Google Tag Manager. Security posture is good with HTTPS enforced and secure forms, though some security headers are not evident and no explicit security policy is published. The WHOIS data is missing or unavailable, which raises some concerns about domain registration transparency but does not detract significantly from the overall legitimacy given the comprehensive business information and social media presence. Overall, the website is professional, secure, and compliant with privacy regulations, making it a trustworthy digital presence for the company.

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

4 findings rated critical or high. Fix these first.

  1. 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.

    • Critical

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

  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

  3. 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';…

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 manufacturing sector, focusing on custom staircases for commercial, public, and private buildings. Their business model combines craftsmanship with modern production technologies, targeting architects, general contractors, and property developers. The website indicates a medium-sized enterprise based in Germany with a century-long tradition. The company leverages digital marketing and social media channels effectively to reach its audience. Partnerships include an internal reporting office linked via a partner domain. The absence of WHOIS data is a notable anomaly but may be due to privacy protection or recent domain registration. The company demonstrates strong branding consistency and trust signals such as detailed contact information and client testimonials.

Security posture

The website employs HTTPS and integrates a consent management platform (Cookiebot) to comply with privacy laws. Contact forms are present with validation, reducing risk of injection attacks. However, no explicit security headers were detected in the provided data, and no published security or incident response policies were found. The lack of a security.txt file or vulnerability disclosure mechanism limits transparency for security researchers. No vulnerabilities or exposed sensitive data were identified in the HTML content. Overall, the security posture is good but could be improved by adding security headers and publishing security policies.

Recommendations

  1. Implement and verify HTTP security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Publish a dedicated security policy and incident response information on the website to improve transparency and preparedness.
  3. Add a security.txt file to facilitate responsible vulnerability disclosure and improve security communication.
  4. Review domain WHOIS registration to ensure transparency and consistency with business claims, or justify privacy protection use.
  5. Continue maintaining and updating privacy compliance mechanisms, including cookie consent and data protection notices.

Technical notes

Notes

The website is built using modern web technologies including Astro framework and Alpine.js for interactivity, with assets and images served via Netlify CDN. The site is mobile-optimized with responsive design and good accessibility features. SEO is supported by proper meta tags and Open Graph data. Google Tag Manager is used for analytics and tracking, integrated with Cookiebot for consent management. The site loads quickly and provides a smooth user experience. There is no evidence of legacy or vulnerable libraries. Technical risks are minimal but could be further mitigated by enhancing security headers and monitoring third-party scripts.
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.
