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

KÄHLER Industrie-Armaturen GmbH is a specialized supplier and service provider of high-quality industrial valves and fittings, primarily serving the energy, petrochemical, and industrial sectors in Germany. The company partners with reputable manufacturers such as Vexve to offer a broad portfolio of products including fully welded ball valves and hot tapping systems. Their business model focuses on B2B sales and comprehensive service offerings including installation training and maintenance support. The website reflects a professional and consistent brand image targeting industrial clients with clear contact channels and product information. Technically, the website is built on a modern stack likely using Shopware CMS, with integration of Google Tag Manager and cookie consent management via Cloud CCM19. The site is mobile optimized and provides a good user experience with clear navigation and relevant content. Performance is moderate with standard web technologies and lazy loading of images. From a security perspective, the site enforces HTTPS and uses consent management for analytics, but lacks explicit security headers and detailed security or incident response policies. No vulnerability disclosure or security.txt file is present, which could be improved to enhance trust and compliance. Privacy and cookie policies are not explicitly found, indicating a gap in GDPR compliance documentation. Overall, the website is trustworthy and professional with a solid business presence, but could benefit from enhanced privacy and security disclosures to improve compliance and user trust. Strategic improvements in security headers and policy transparency are recommended to strengthen the security posture.

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

8 findings rated critical or high. Fix these first.

  1. GDPR outside view

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

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • 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

  2. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • Critical

      Critical Service Exposed: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

      What to do: Immediately restrict access to MySQL using firewall or VPN

      • NIS2 21(2)(e)

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 · found on this site
  • 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

KÄHLER Industrie-Armaturen GmbH holds a niche position in the German industrial valve market, focusing on energy and petrochemical sectors. Their competitive advantage lies in partnerships with leading manufacturers like Vexve and a comprehensive service offering including hot tapping technology and maintenance. The business operates primarily as a B2B supplier with a direct online shop and telephone consultation. Growth indicators include a broad product catalog and specialized services such as training and repair. The company maintains a professional digital presence with customer testimonials and downloadable resources, supporting credibility and customer engagement. The partnership ecosystem includes reputable valve manufacturers, enhancing product quality and market reach.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforced and use of Google Tag Manager integrated with cookie consent management. However, the absence of security headers such as Content-Security-Policy, X-Frame-Options, and X-XSS-Protection reduces defense-in-depth. No explicit security policies or incident response contacts are published, limiting transparency and preparedness communication. There is no vulnerability disclosure or security.txt file, which are best practices for responsible security management. No visible vulnerabilities or exposed sensitive data were detected. Overall, the security posture is adequate but could be significantly improved by adopting standard security headers, publishing security policies, and establishing a vulnerability disclosure process.

Recommendations

  1. Implement and configure security headers including Content-Security-Policy, X-Frame-Options, and X-XSS-Protection to enhance browser security.
  2. Publish a comprehensive privacy policy and cookie policy with clear GDPR compliance statements and user consent mechanisms.
  3. Add a dedicated security policy page and incident response contact information to improve transparency and readiness.
  4. Establish a vulnerability disclosure program and publish a security.txt file to encourage responsible reporting and improve trust.
  5. Regularly audit third-party scripts and libraries to ensure no vulnerable components are included and maintain up-to-date dependencies.

Technical notes

Notes

The website is built on a modern e-commerce platform, likely Shopware, utilizing standard web technologies such as HTML5, CSS, JavaScript, and Bootstrap for responsive design. It integrates Google Tag Manager for analytics and Cloud CCM19 for cookie consent management. Images are lazy loaded for performance optimization. The site is mobile-friendly with good navigation clarity and SEO meta tags including Open Graph and Twitter cards. However, no advanced frameworks or server-side technologies are explicitly detected. Performance is moderate, with potential for improvement in loading speed and accessibility features. The technical infrastructure supports a professional online presence but could benefit from enhanced security configurations and performance tuning.
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.
