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

GMI installatietechniek is a Dutch company specializing in the design, installation, maintenance, and management of electrical installations across retail, luxury housing, utility, and industrial sectors. The company targets businesses and clients within the Netherlands, positioning itself as a niche regional service provider. The website is professionally designed using the Wix platform, featuring structured data for local business identification and contact information, enhancing its digital presence. Technically, the site leverages Wix's Thunderbolt framework and standard web technologies, offering moderate performance and good mobile optimization. Security-wise, the site enforces HTTPS and includes scripts to harden fetch and XHR requests, but lacks visible security headers and formal privacy or cookie policies, indicating areas for improvement. The absence of WHOIS registration data raises legitimacy concerns, although the professional presentation and consistent business information partially mitigate this risk. Overall, the site demonstrates a moderate security posture and digital maturity but requires enhancements in compliance and transparency to strengthen trust and regulatory adherence.

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 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. GDPR outside view

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

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

  3. 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

  4. DNS health

    DNS sends visitors and email to the right servers. Misconfigured records can cause outages or let someone redirect your traffic.

    • High

      Domain Expires Soon

      Domain expires in 17 days

      What to do: Renew domain registration before expiration

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 and retail sectors, focusing on electrical installation services for specialized markets such as luxury housing and industrial clients. Its business model revolves around providing comprehensive electrical solutions, including design, installation, and ongoing maintenance. The website's content and structured data suggest a small-sized enterprise with a localized market focus in the Netherlands. The lack of WHOIS data and absence of privacy and cookie policies indicate potential gaps in operational transparency and compliance. No evident partnerships or subsidiaries are identified from the domain or website content. The company appears to maintain a straightforward service offering without extensive digital marketing or analytics integration, suggesting a traditional business approach with moderate digital engagement.

Security posture

The website benefits from HTTPS encryption, ensuring secure data transmission. It employs JavaScript-based security enhancements to restrict unauthorized fetch and XHR requests, reflecting an awareness of client-side security risks. However, the absence of key security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options reduces its defense-in-depth capabilities. No forms or data collection points were detected, minimizing immediate risks of input-based attacks, but also limiting user interaction. The lack of privacy and cookie policies, as well as no visible incident response or vulnerability disclosure mechanisms, indicates compliance and security governance gaps. The missing WHOIS registration data further complicates trust evaluation. Overall, the security posture is moderate but would benefit from formalized policies, enhanced header configurations, and transparent incident response processes.

Recommendations

  1. Implement and publish a comprehensive privacy policy and cookie policy to improve GDPR compliance and user trust.
  2. Add essential security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to strengthen security posture.
  3. Verify and update WHOIS registration information to ensure domain legitimacy and transparency.
  4. Establish a vulnerability disclosure policy or security.txt file to facilitate responsible security communication.
  5. Enhance accessibility features and conduct regular security audits of third-party scripts and integrations.

Technical notes

Notes

The website is built on the Wix platform using the Thunderbolt framework, leveraging modern JavaScript and CSS technologies. It is hosted by Wix, which provides reliable infrastructure and SSL certificates, ensuring HTTPS availability. The site demonstrates good mobile optimization and basic SEO practices, including meta tags and structured data. Performance is moderate, typical for Wix-hosted sites, with no significant technical debt observed. However, the site lacks advanced accessibility features and comprehensive privacy and security configurations. No analytics or tracking services were detected, indicating minimal data collection. The technical setup is stable but could be improved by integrating enhanced security headers, privacy compliance tools, and accessibility enhancements to meet higher standards.
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.
