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. 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: 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

  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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • 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';…

  3. 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

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

MantelZ operates in the non-profit healthcare support sector, targeting unpaid caregivers and healthcare professionals. Its business model revolves around community support, information dissemination, and volunteer coordination. The organization leverages partnerships, notably with maatjez.nl, to extend its service offerings. The website content and domain registration data are consistent, reflecting a legitimate and regionally focused entity. The site’s content quality and navigation support effective user engagement, while the use of GDPR-compliant tools indicates a mature approach to privacy. Growth indicators include active event organization and newsletter subscription options. The partnership ecosystem and clear contact channels enhance operational transparency and user trust.

Security posture

The website maintains a good security posture with enforced HTTPS and integration of Google reCAPTCHA v3 to protect forms from spam and abuse. Cookie consent is managed via a reputable GDPR plugin, Complianz, with opt-in mechanisms for user privacy. However, explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options are not evident in the HTML source, which could be improved to harden security further. No exposed sensitive data or vulnerable libraries were detected. Some broken lazy-loaded images may affect user experience but do not pose direct security risks. Incident response and security policy information are not publicly available, which is a potential gap in transparency and readiness. Overall, the site demonstrates a moderate to good security maturity suitable for its non-profit context.

Recommendations

  1. Implement and verify comprehensive security headers (CSP, X-Frame-Options, X-Content-Type-Options) to enhance protection against common web attacks.
  2. Fix broken lazy-loaded images to improve user experience and reduce potential phishing or trust issues.
  3. Publish a dedicated security policy and incident response contact information to improve transparency and preparedness.
  4. Regularly update WordPress core, themes, and plugins to mitigate emerging vulnerabilities.
  5. Consider periodic security audits and penetration testing to identify and remediate hidden risks.

Technical notes

Notes

The website is built on WordPress with a modern tech stack including Gravity Forms for form management, Yoast SEO for search optimization, and Complianz for cookie consent. It uses Google Fonts, Google Tag Manager, and Google reCAPTCHA v3 for enhanced functionality and security. Hosting assets are served via Amazon S3, indicating a hybrid hosting approach. Performance is moderate with some lazy-load image errors that should be addressed. The site is mobile-optimized and accessible, with good SEO metadata and structured data (JSON-LD) for enhanced search engine understanding. Technical debt appears low, but improvements in security headers and image handling would enhance robustness. Overall, the technical infrastructure supports the business goals effectively with room for optimization.
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.
