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

GSR Ventiltechnik GmbH & Co. KG is a German manufacturer specializing in magnet- and pressure-controlled valves for liquids and gases, with over 50 years of industry experience. The company offers a broad portfolio of over 1,000 valve options serving diverse sectors such as hydrogen, gas, water treatment, shipbuilding, and food industry. The website reflects a professional and consistent brand presence, supported by a modern TYPO3 CMS infrastructure and Bootstrap framework, ensuring good mobile optimization and user experience. The company is a subsidiary of INDUS HOLDING AG, reinforcing its market credibility. Technically, the website employs modern web technologies including jQuery, Bootstrap 5, and integrates marketing and analytics tools such as Google Tag Manager and Leadinfo, with a compliant cookie consent mechanism. Security posture is solid with HTTPS enforced and no exposed sensitive data, though the absence of explicit security headers and published security policies suggests room for improvement. The domain is newly registered in 2024, which is consistent with a regional or new domain strategy, while the main business history is much older. Overall, the website demonstrates a good balance of content quality, technical implementation, and privacy compliance, supporting the company's industrial manufacturing business. Strategic enhancements in security policy transparency and technical security headers would further strengthen trust and compliance.

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

6 findings rated critical or high. Fix these first.

  1. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  2. 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • 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';…

  3. 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.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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

GSR Ventiltechnik holds a strong position in the industrial valve manufacturing market, leveraging decades of experience and a wide product range tailored to critical sectors like energy and transportation. Their business model focuses on manufacturing, technical service, and global distribution, supported by digital tools such as valve search and detailed datasheets. The company benefits from its association with INDUS HOLDING AG, enhancing financial and operational stability. The website's multilingual support and participation in industry events indicate active market engagement and growth orientation. Marketing and analytics integrations suggest a data-driven approach to customer engagement and lead generation.

Security posture

The website maintains a good security baseline with HTTPS and cookie consent mechanisms. However, it lacks visible security headers such as Content Security Policy, HSTS, and X-Frame-Options, which are recommended to mitigate common web vulnerabilities. No incident response or security policy information is published, which could impact transparency and readiness perception. The use of multiple third-party tracking scripts necessitates ongoing monitoring for privacy compliance. No vulnerabilities or exposed sensitive data were detected in the HTML content. Overall, the security posture is adequate but could be enhanced by adopting best practices and publishing security policies.

Recommendations

  1. Implement comprehensive HTTP security headers including CSP, HSTS, and X-Frame-Options.
  2. Publish a clear security policy and incident response information on the website.
  3. Introduce a security.txt file to facilitate vulnerability disclosure.
  4. Enhance accessibility features to meet higher compliance standards.
  5. Regularly audit and update third-party scripts to minimize security risks.

Technical notes

Notes

The website is built on TYPO3 CMS with Bootstrap 5, jQuery, and Photoswipe for UI components, indicating a mature and maintainable technology stack. It integrates marketing and analytics tools such as Google Tag Manager, Leadinfo, and Appointlet for appointment scheduling. The site is mobile-optimized with responsive design and good navigation clarity. Performance is moderate, with potential improvements in loading speed by optimizing scripts and images. The domain is hosted under a reputable registrar, InterNetX GmbH. Technical debt appears low, but security header implementation and accessibility improvements are recommended to modernize the infrastructure further.
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.
