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

Nationale Onderwijs Monitors is a specialized service provider in the education sector in the Netherlands, offering monitoring, benchmarking, and survey tools to help educational organizations improve their performance through data-driven insights. The company operates a professional website built with modern React and Gatsby technologies, providing centralized access to monitoring data and a user-friendly survey application. The website is well-designed, mobile-optimized, and includes essential legal documents such as privacy and terms of service statements, indicating a commitment to compliance and professionalism. However, the absence of a cookie consent mechanism and security headers suggests room for improvement in privacy compliance and security hardening. The domain is registered since 2014 with a reputable registrar, consistent with the business's operational history. Overall, the website demonstrates a moderate to good level of digital maturity and security posture, suitable for its niche educational market.

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

7 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 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

The company targets educational institutions seeking to measure and improve their organizational performance through data analytics and benchmarking. Its business model revolves around providing SaaS-like monitoring and survey tools accessible via a centralized platform. The presence of partnerships with design and development firms indicates a collaborative ecosystem supporting the website's quality and functionality. The use of Google Analytics and Tag Manager reflects standard marketing and user behavior tracking practices. The company appears to maintain a focused market position within the Dutch education sector, with a small-sized organizational footprint and no evident subsidiaries or parent companies. The website content and structure support clear communication of services and value propositions, enhancing customer engagement and trust.

Security posture

The website enforces HTTPS, ensuring encrypted communications, and avoids exposing sensitive data in its HTML content. However, it lacks several recommended security headers such as Content-Security-Policy and X-Frame-Options, which could mitigate risks like clickjacking and cross-site scripting. No explicit security policies or incident response contacts are published, which limits transparency in handling security incidents. The absence of DNSSEC reduces DNS security robustness. Forms are present but no detailed analysis of input sanitization or backend security is possible from the HTML alone. Overall, the security posture is adequate but could be significantly improved by implementing standard security headers, publishing security policies, and enabling DNSSEC.

Recommendations

  1. Implement a cookie consent banner to comply with GDPR and enhance user privacy transparency.
  2. Enable DNSSEC for the domain to improve DNS security and prevent spoofing.
  3. Add essential security headers such as Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options.
  4. Publish a dedicated security policy page and provide incident response contact information to improve transparency and trust.
  5. Regularly audit and update third-party libraries and scripts to avoid vulnerabilities and maintain security hygiene.

Technical notes

Notes

The website is built using React and Gatsby, indicating a modern static site generation approach that benefits performance and SEO. Google Analytics and Tag Manager are integrated for user tracking and analytics. The site is mobile-optimized with responsive design elements and uses external font services (Typekit). Hosting details are limited but the domain registrar is Hostnet B.V., a known Dutch provider. Performance is moderate with preloading of scripts and images. Accessibility is basic but could be enhanced with ARIA attributes and better semantic markup. SEO is basic with meta tags and Open Graph tags present but no JSON-LD structured data detected. The site lacks a CMS, relying on static generation, which reduces attack surface but may limit dynamic content management.
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.
