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 Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics, Google APIs, Google Ads

      What to do: Document all third-party data sharing in your privacy policy

  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 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';…

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

EZÚ operates as an essential service provider in the certification and testing industry, targeting businesses requiring compliance and quality assurance for electrotechnical and related products. Its long domain history and state enterprise status provide competitive advantages and trust. The business model includes direct service delivery, metrology, calibration, and educational offerings through partner domains. The company maintains a comprehensive accreditation portfolio, enhancing market credibility. Growth potential is supported by expanding cybersecurity certification services and educational programs. Partnerships with related educational and career platforms indicate a strategic ecosystem approach.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, use of Cloudflare DNS, and inclusion of security headers. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of a published security policy or incident response page and lack of a vulnerability disclosure mechanism represent gaps in transparency and readiness. The use of reCAPTCHA scripts indicates protection against automated abuse. Overall, the security maturity is good but could be enhanced by formalizing policies and disclosure practices.

Recommendations

  1. Implement a visible cookie consent banner to ensure GDPR compliance and user transparency.
  2. Publish a dedicated security policy and incident response page to improve trust and preparedness.
  3. Create and maintain a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  4. Enhance website accessibility features to meet broader compliance and usability standards.
  5. Regularly audit and update third-party scripts and plugins to mitigate potential vulnerabilities.

Technical notes

Notes

The website is built on a modern WordPress CMS platform using Elementor for page building and WooCommerce for product catalog management. It integrates Google Tag Manager and Google Maps APIs for analytics and location services. Hosting and DNS are managed via WEDOS and Cloudflare, providing reliable infrastructure and DNS security. Performance is moderate with room for optimization, especially in mobile responsiveness and accessibility. SEO is well addressed through Yoast SEO plugin and structured data (JSON-LD). Technical risks are minimal but include potential dependency on third-party scripts and lack of advanced accessibility features.
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.
