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

5 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 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';…

  2. 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

  3. Network security

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

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality

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 valves for industrial applications such as hydrogen fueling, gas, water treatment, shipbuilding, and food industry. Its business model centers on product development, manufacturing, and global distribution. The presence of a valve search tool and technical service offerings indicates a customer-centric approach. The parent company INDUS HOLDING AG provides additional corporate backing. The company targets industrial clients requiring reliable valve solutions, with growth potential in emerging sectors like hydrogen technology. The website's multilingual support and event participation reflect an international market orientation.

Security posture

The website demonstrates a mature security posture with HTTPS enabled and cookie consent mechanisms that respect user privacy. No critical vulnerabilities or exposed sensitive data were detected. However, the absence of a published security policy, incident response contacts, and a security.txt file indicates gaps in formal security governance and vulnerability disclosure practices. The use of third-party analytics and tracking services is managed with consent, aligning with GDPR. Security headers were not explicitly detected, suggesting room for improvement in HTTP security configurations.

Recommendations

  1. Publish a dedicated security policy page outlining security governance and practices.
  2. Provide clear incident response contact information to facilitate vulnerability reporting.
  3. Implement and publish a security.txt file to formalize vulnerability disclosure.
  4. Enhance HTTP security headers such as Content Security Policy (CSP) and HTTP Strict Transport Security (HSTS).
  5. Improve website accessibility features to comply with WCAG standards and enhance user experience.

Technical notes

Notes

The website leverages TYPO3 CMS and Bootstrap 5 for a modern, responsive design. It uses jQuery and Photoswipe for UI enhancements and integrates multiple third-party services including Google Tag Manager, Leadinfo, and Appointlet for analytics and marketing. The site is mobile-optimized with good navigation clarity and SEO practices. Performance is moderate, with potential improvements in loading speed and accessibility. No critical technical debt or outdated libraries were identified. Hosting provider details are not explicit, but domain and DNS data indicate professional hosting arrangements.
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.
