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

GWF MessSysteme AG is a well-established Swiss company specializing in innovative measurement systems for energy, water, and building technology sectors. With a history spanning over 125 years, the company has evolved from a manufacturer of gas and water meters to a system integrator offering digital and IoT solutions for smart cities, buildings, industries, and infrastructure. Their market position is strong in Switzerland with growing international presence supported by partnerships and service offices. The website reflects a mature digital infrastructure built on WordPress with modern SEO and accessibility practices. Security posture is robust with HTTPS, security headers, CAPTCHA protections, and cookie consent mechanisms in place. However, explicit security policies and incident response contacts are not publicly available, representing an area for improvement. Overall, the site is professional, trustworthy, and compliant with GDPR requirements.

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

7 findings rated critical or high. Fix these first.

  1. 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: SMB

      Port 445 (SMB) is publicly accessible - SMB - Windows file sharing, high risk

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

      • 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
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection
    • 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)
      • 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
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  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 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. GDPR outside view

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

    • 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

  4. 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 · 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

GWF targets utility providers, industrial clients, and infrastructure operators with precision measurement devices and digital solutions. Their business model combines product manufacturing with software and service offerings, enabling customers to monitor and optimize resource consumption. The company leverages innovation and digitalization to maintain competitive advantage and expand internationally. Their partnership ecosystem includes specialized technology providers and global distribution networks. The company demonstrates growth through active event participation and industry certifications. The website content and structure support clear communication of their value proposition and market leadership.

Security posture

The website employs strong security measures including HTTPS with excellent SSL configuration, comprehensive security headers, and anti-spam CAPTCHA on forms. Cookie management is handled via a reputable plugin with explicit user consent, supporting GDPR compliance. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of a publicly available security policy or incident response contact limits transparency. There is no evidence of a vulnerability disclosure program or security.txt file. Overall, the security maturity is high but could be enhanced by publishing formal security governance documents and incident handling procedures.

Recommendations

  1. Publish a dedicated security policy page outlining security governance and controls.
  2. Provide explicit incident response contact information such as security@ or abuse@ email addresses.
  3. Implement and publicize a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Regularly review and update third-party scripts and plugins to mitigate potential vulnerabilities.
  5. Enhance user trust by adding visible trust seals or certifications related to security and privacy.

Notes

The website is built on WordPress CMS with a modern tech stack including jQuery, Swiper.js for sliders, and Yoast SEO for optimization. It uses Borlabs Cookie for GDPR-compliant cookie management and FriendlyCaptcha for form spam protection. Google Analytics and Google Tag Manager are integrated for analytics and marketing. The site is mobile-optimized with responsive images and accessibility considerations. Performance is moderate, with opportunities to improve load times by optimizing assets and leveraging caching. The technical implementation is solid with good SEO and accessibility standards, supporting a professional 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.
