Security score

49/100

Risk levelHigh

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

GWF AG operates a professional website focused on precision flow measurement solutions for hydropower plants and large-scale water applications. The company positions itself as an experienced and innovative provider with a global footprint and a history of product development since 2005. The website is well-structured, content-rich, and targets hydropower industry professionals and infrastructure managers. Technically, the site is built on WordPress with modern plugins for SEO, analytics, and cookie compliance, hosted on Azure DNS infrastructure. Security posture is good with HTTPS and CAPTCHA protections, though some security headers and explicit policies are missing. The WHOIS data shows inconsistencies with a future domain creation date, which raises concerns about domain legitimacy despite the professional appearance and external trust signals. Overall, the site is trustworthy and professional but would benefit from clarifying domain registration details and publishing formal 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

9 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. 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

  3. 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';…

  4. 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

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 AG is positioned as a specialized B2B technology provider in the energy sector, focusing on hydropower efficiency and safety through advanced flow measurement systems. Their business model includes product sales, turnkey installation, and consulting services. The company demonstrates steady growth with over 800 installations worldwide and a timeline of innovations. Their partnership ecosystem includes their main corporate domain gwf.ch and a LinkedIn presence. The target customers are hydropower plant operators and large-scale water infrastructure managers. The company emphasizes compliance, transparency, and sustainable water use, aligning with regulatory pressures. No direct revenue or financial data is available, but the medium size and global reach indicate a stable market position.

Security posture

The website enforces HTTPS and uses CAPTCHA to protect forms, indicating a baseline security awareness. Cookie consent is managed via Borlabs Cookie, supporting GDPR compliance. However, the absence of security headers like Content-Security-Policy and lack of published security or incident response policies are gaps. No vulnerabilities or exposed sensitive data were detected in the HTML content. The WHOIS data inconsistency is a risk factor for trust but does not directly impact website security. Overall, the security posture is good but could be improved with additional headers and transparency on security policies.

Recommendations

  1. Implement standard security headers such as Content-Security-Policy, X-Frame-Options, and X-XSS-Protection to enhance browser security.
  2. Enable DNSSEC on the domain to improve DNS integrity and prevent spoofing.
  3. Publish a dedicated security policy page and provide incident response contact information to improve transparency and trust.
  4. Clarify and correct domain WHOIS registration details to align with the company's claimed history and improve legitimacy.
  5. Continue monitoring and updating third-party libraries and plugins to avoid vulnerabilities.

Technical notes

Notes

The website uses a modern WordPress CMS with well-known plugins for SEO (Yoast), analytics (Google Site Kit), forms (WPForms), and cookie management (Borlabs Cookie). It leverages jQuery and Swiper.js for UI components and Friendly Captcha for bot protection. Hosting is via Azure DNS servers, indicating a reliable infrastructure. Performance is moderate with good mobile optimization and SEO practices. Accessibility is basic but present. The site uses structured data (JSON-LD) for SEO and social media integration. No major technical debt or outdated technologies were detected, but security headers are missing which is a technical gap.
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.
