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

6 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

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • 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

    • 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

  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. 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
  • 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

Metrel GmbH operates in the energy and technology sectors, focusing on electrical safety and measurement instruments. Their competitive advantage lies in a broad product range, including multifunctional testers, software solutions, and training services. The business model is B2B with a strong partner and distribution network across Europe. Revenue streams likely include product sales, calibration and repair services, software subscriptions, and training seminars. The company maintains a consistent brand presence and leverages digital marketing tools effectively. Growth indicators include new product announcements and cloud service offerings. The partnership ecosystem includes distributors and seminar partners. Strategic observations suggest a focus on innovation and customer support to maintain market position.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, presence of key security headers, and use of reCAPTCHA on forms to prevent abuse. No exposed sensitive data or vulnerable libraries were detected in the provided content. However, the absence of a published security policy or incident response contact limits transparency. There is no evidence of a vulnerability disclosure program or security.txt file. GDPR compliance is evident through privacy and cookie policies with consent mechanisms. Overall, the security culture appears adequate for the business type but could be enhanced by publishing explicit security policies and incident response procedures.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and commitments.
  2. Establish and publicize an incident response contact or page to improve transparency.
  3. Implement a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  4. Enhance website accessibility features to meet compliance standards.
  5. Regularly review and update third-party scripts and tracking tools to mitigate vulnerabilities.

Technical notes

Notes

The website is built on a modern technology stack including jQuery, Modernizr, Bootstrap CSS, and integrates Google Analytics, Google Tag Manager, and Facebook Pixel for analytics and marketing. Hosting is via Microsoft Azure DNS, indicating reliable infrastructure. Performance is moderate with room for optimization. The site is mobile-optimized and SEO-friendly with proper meta tags and Open Graph data. No CMS was explicitly detected, suggesting a custom or proprietary platform. Technical risks are minimal but include dependency on multiple third-party scripts which require regular security audits. Overall, the technical implementation supports business operations effectively with opportunities for performance and accessibility improvements.
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.
