Security score

88/100

Risk levelLow

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

Unternehmensgruppe Gretsch-Unitas operates as a leading manufacturer and supplier of window and door technology, automatic entrance systems, and building management systems. The company serves a broad market including architects, builders, and facility managers, offering comprehensive hardware and system solutions under its GU, BKS, FERCO, and GU Automatic brands. The website reflects a mature digital presence with detailed product and service information, consistent branding, and active social media engagement. Technically, the site is built on TYPO3 CMS with modern JavaScript libraries and includes GDPR-compliant cookie management via Usercentrics. Security posture is solid with HTTPS and secure forms, though it lacks explicit security policies and incident response contacts. Overall, the domain appears legitimate despite missing WHOIS data, supported by professional content and branding.

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, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

The GU Group holds a strong market position in manufacturing architectural hardware and building management systems, targeting commercial and residential construction sectors. Its business model focuses on product manufacturing combined with system and project solutions, supported by systematic service offerings. The company maintains multiple subsidiary brands, enhancing its market reach and product diversity. The website's structured navigation and comprehensive content indicate a well-organized business operation with clear customer engagement strategies. Partnerships and service portals further support its ecosystem. The absence of direct contact emails or phone numbers suggests a preference for controlled communication channels via forms.

Security posture

The website demonstrates a good security baseline with HTTPS enforced and cookie consent mechanisms implemented. However, the absence of visible security headers such as Content-Security-Policy and lack of published security policies or incident response information represent gaps in transparency and readiness. No vulnerabilities or exposed sensitive data were detected in the HTML content. The site uses secure forms with validation, reducing risk of injection attacks. Overall, the security maturity is moderate to good but could be improved by publishing security documentation and enhancing HTTP headers.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and compliance.
  2. Provide clear incident response contact details, including abuse and security email addresses.
  3. Implement and configure security headers like Content-Security-Policy, X-Content-Type-Options, and Strict-Transport-Security.
  4. Create and publish a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  5. Enhance accessibility features to meet recognized standards and improve user experience for all users.

Notes

The website is built on TYPO3 CMS, leveraging jQuery and Bootstrap frameworks for responsive design and interactivity. SEO is enhanced via Yoast SEO for TYPO3, and cookie management is handled by Usercentrics CMP, indicating compliance with privacy regulations. Performance is moderate with optimized images and lazy loading. Mobile optimization is good, though accessibility features are basic and could be improved. No hosting provider details were identified from the HTML content. The technical stack is modern and well-maintained, supporting a professional and functional user experience.
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.
