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

Rotarex is a well-established global manufacturer specializing in premium gas control products including valves, pressure regulators, and complete gas systems. Founded in Luxembourg in 1922, the company holds a strong market position as a world-leading producer in the energy sector, targeting industrial and commercial gas system users. Their website reflects a professional and consistent brand image with clear business information and contact details. Technically, the site employs a modern technology stack including jQuery, Fancybox, Google Tag Manager, and Hotjar, hosted on Azure DNS infrastructure. The website is mobile-optimized and SEO-friendly, providing a good user experience. Security-wise, the site uses HTTPS and a robust cookie consent mechanism via Cookiebot, but lacks DNSSEC and explicit security policies or incident response contacts. Extensive user tracking is observed through multiple analytics and marketing tools, with good privacy compliance via cookie consent but no visible privacy policy or terms of service. Overall, the domain's WHOIS data supports legitimacy with a long registration history and consistent registrant information. The website is trustworthy and professionally maintained but could improve transparency around privacy and security policies.

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

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

Rotarex operates in the energy sector with a manufacturing business model focused on gas valves and systems. Their competitive advantage lies in their long history, global reach, and product quality. The company targets industrial clients requiring gas safety and control solutions. The website indicates a mature digital presence with integrated marketing and analytics tools, suggesting active customer engagement and lead generation efforts. Partnerships with platforms like LinkedIn, Hubspot, and Leadfeeder indicate a strategic approach to marketing and sales. The absence of privacy and terms policies is a gap in compliance and customer trust. No parent or subsidiary companies are explicitly mentioned, indicating a standalone corporate structure or undisclosed affiliations.

Security posture

The website demonstrates a moderate to good security posture with HTTPS enforced and a comprehensive cookie consent mechanism that aligns with GDPR requirements. However, the lack of DNSSEC and absence of security headers or published security policies reduce the overall security maturity. No incident response or vulnerability disclosure information is provided, which could hinder timely communication in case of security events. The use of multiple third-party tracking and marketing services increases the attack surface and privacy risks, though mitigated by user consent. No critical vulnerabilities or exposed sensitive data were detected in the analyzed content.

Recommendations

  1. Enable DNSSEC to enhance DNS security and prevent spoofing.
  2. Publish a clear privacy policy and terms of service to improve compliance and user trust.
  3. Add security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  4. Establish and publish an incident response policy and contact channels (e.g., security@ or abuse@ emails).
  5. Review third-party tracking tools to minimize privacy risks and ensure compliance with data protection regulations.

Technical notes

Notes

The website uses a modern and diverse set of JavaScript libraries and frameworks including jQuery, Fancybox, Tiny-slider, and Slick-carousel for UI components and interactivity. Google Tag Manager and Google Analytics are used for analytics, while Hotjar and Leadfeeder provide user behavior tracking and lead generation capabilities. The site is hosted with Azure DNS services, indicating reliable infrastructure. Performance is moderate with good mobile optimization and SEO practices. No CMS was explicitly detected, suggesting a custom or proprietary platform. The site uses asynchronous loading for scripts to improve load times. Accessibility features are basic but present. Technical debt appears low, but improvements in security headers and DNS configuration are recommended to reduce risks.
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.
