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

GWF MessSysteme AG is a well-established Swiss company with a 125-year history specializing in innovative measurement systems for energy, water, and infrastructure sectors. The company operates primarily in the energy industry, offering a broad portfolio of products and digital solutions targeting utilities, industrial clients, and building technology professionals. Their market position is strong in Switzerland with growing international presence supported by partnerships and subsidiaries. The website reflects a professional and comprehensive digital presence with multilingual support and detailed business information. Technically, the website is built on WordPress with a modern tech stack including Yoast SEO, WP Rocket, and Borlabs Cookie for privacy compliance. However, performance is moderate to slow, and accessibility is basic. The site is mobile optimized and SEO friendly. Security posture is currently weak due to the absence of a valid SSL certificate and lack of modern TLS protocols, which poses a significant risk to user data protection and trust. Privacy compliance is well addressed with clear privacy and cookie policies and active consent mechanisms. Contact information is clearly presented, though no explicit security or incident response policies are found. Overall, the website is trustworthy and professional but requires urgent improvements in SSL/TLS configuration to enhance security and user trust. Strategic recommendations include immediate installation of a valid SSL certificate, enabling modern TLS protocols, strengthening security headers, and continuous monitoring of privacy compliance and security best practices.

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

9 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

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

  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.

    • Critical

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

  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.

    • 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

  4. 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';…

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.

Business context

Business profile

GWF MessSysteme AG operates as a manufacturer and system integrator in the energy measurement sector, focusing on Smart City, Smart Building, Smart Industry, and Smart Infrastructure applications. Their competitive advantage lies in their long-standing history, Swiss quality manufacturing, and innovative digital solutions including IoT and software platforms. Revenue streams likely include product sales, system integration services, and software subscriptions. The company targets utilities, industrial clients, and infrastructure operators, with a strong emphasis on sustainability and resource efficiency. Their partnership ecosystem includes specialized technology providers and service platforms, supporting international expansion. The company demonstrates growth through innovation awards and export nominations, indicating a forward-looking strategy and market relevance.

Security posture

The current security maturity level of the website is low due to the lack of a valid SSL certificate and disabled TLS protocols, which exposes users to potential data interception and undermines trust. Security headers such as HSTS, X-Frame-Options, X-Content-Type-Options, and X-XSS-Protection are present but could be enhanced by including subdomains and preload directives. No incident response or vulnerability disclosure information is publicly available, indicating a gap in security transparency. The website uses secure forms with CAPTCHA protection, and privacy compliance is strong. However, the absence of modern encryption and session management features represents a critical vulnerability that should be addressed immediately to protect business operations and customer data.

Recommendations

  1. Install and maintain a valid SSL/TLS certificate to enable HTTPS and protect data in transit.
  2. Enable and configure modern TLS protocols (TLS 1.2 and TLS 1.3) and disable legacy protocols to improve encryption strength.
  3. Enhance security headers by including HSTS with includeSubDomains and preload options.
  4. Publish a security policy and incident response contact information to improve transparency and trust.
  5. Regularly audit and update website plugins and dependencies to avoid vulnerabilities and ensure compliance.

Technical notes

Notes

The website is hosted on an Apache server with Azure DNS nameservers, running WordPress CMS with multiple plugins for SEO, performance optimization, privacy compliance, and form handling. The tech stack includes jQuery, Swiper.js for sliders, Friendly Captcha for bot protection, and Google Analytics for tracking. Performance metrics indicate slow loading times, possibly due to large images and multiple scripts. The site is mobile optimized and uses modern web standards but lacks advanced accessibility features. Technical debt is present in the form of missing SSL and outdated TLS configuration, which poses operational risks. Modernization opportunities include upgrading SSL/TLS, optimizing resource loading, and enhancing accessibility and security frameworks.
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.
