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

3 findings rated critical or high. Fix these first.

  1. 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';…

  2. 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 SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

NBN operates in the standards and compliance sector, serving a broad audience including SMEs, governments, and international companies. Its business model includes selling standards, offering subscriptions, providing training courses, and facilitating public consultation on standards. The company leverages partnerships with ISO and other entities, and maintains a strong brand presence in Belgium. The website's content and structure support lead generation and customer engagement through configurators, webinars, and downloadable whitepapers. The presence of career portals and educational platforms indicates a mature ecosystem. Market positioning is strong nationally with potential for international reach via multilingual support.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, use of Google reCAPTCHA and Cloudflare Turnstile to mitigate automated abuse, and integration of security-conscious third-party services. No sensitive data is exposed in the HTML. However, explicit security headers like Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options were not explicitly detected and should be confirmed. There is no publicly available security policy or incident response information, which could be improved to enhance transparency and trust. Overall, the site is secure for typical business use but could benefit from publishing security documentation and vulnerability disclosure processes.

Recommendations

  1. Verify and explicitly implement security headers such as CSP, X-Frame-Options, and X-Content-Type-Options to harden security.
  2. Publish a dedicated security policy and vulnerability disclosure page to improve transparency and incident response readiness.
  3. Regularly audit third-party libraries and dependencies for vulnerabilities and update them promptly.
  4. Enhance visibility of data protection officer contact or GDPR compliance details to strengthen privacy trust.
  5. Continue monitoring and optimizing website performance and accessibility to maintain excellent user experience.

Technical notes

Notes

The website is built on the Webflow platform, leveraging modern web technologies including Google Tag Manager, HubSpot forms, Weglot for multilingual support, and analytics tools like Microsoft Clarity and Leadinfo. It uses Google reCAPTCHA and Cloudflare Turnstile for bot protection. The hosting is via Webflow's CDN, ensuring fast load times and global availability. The site is mobile-optimized and accessible with ARIA attributes and keyboard navigation support. SEO is supported by proper meta tags, Open Graph, and structured data for FAQs. The technical implementation is robust with no broken elements detected. Opportunities exist to enhance security headers and publish more detailed security and privacy documentation.
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.
