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 entity within the technology and healthcare sectors, providing critical certification and testing services that support regulatory compliance and market access. Its state enterprise status and long domain history enhance credibility. The business model focuses on service delivery to manufacturers and businesses requiring product certification, with additional offerings in metrology, cybersecurity certification, and education. The partnership with recruitment platforms indicates active talent acquisition. The company maintains a strong portfolio of ISO and industry-specific certifications, reinforcing its competitive advantage and market position.

Security posture

The website demonstrates a solid security foundation with enforced HTTPS, use of Cloudflare DNS, and implementation of security headers. Forms are protected with Google reCAPTCHA, reducing spam and abuse risks. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of a public vulnerability disclosure policy and incident response contact details suggests areas for enhancement in security transparency and readiness. Compliance with GDPR is evident through a comprehensive privacy policy and cookie consent mechanism. Overall, the security posture is robust but could benefit from formalized disclosure and response processes.

Recommendations

  1. Publish a security.txt file or vulnerability disclosure policy to improve transparency and encourage responsible reporting.
  2. Add explicit incident response contact information, such as a dedicated security or abuse email address.
  3. Regularly review and update third-party scripts and plugins to mitigate potential vulnerabilities.
  4. Enhance cookie consent mechanisms to provide clearer user control and transparency.
  5. Implement multi-factor authentication for user accounts to strengthen access security.

Technical notes

Notes

The website is built on a modern WordPress platform using Elementor for page building and WooCommerce for e-commerce capabilities. It integrates Google Tag Manager and Google Maps API for analytics and location services. Hosting and DNS are managed by reputable providers (WEDOS and Cloudflare), ensuring reliability and security. Performance is moderate with good mobile optimization and accessibility features. SEO is well-implemented with Yoast SEO plugin and structured data (JSON-LD). The site uses asynchronous loading for scripts and employs caching and CDN services indirectly via Cloudflare. Technical debt appears low, but continuous monitoring and updates are recommended to maintain security and performance.
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.
