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

NBN is the Belgian national standards body providing trusted knowledge and services related to standards for Belgian and international companies, governments, and organizations. Their offerings include a standards purchasing platform, participation in standards development, management systems training, and a public portal for commenting on standards. The website is professionally designed, multilingual, and trusted by over 700 companies, positioning NBN as a key player in the standards domain in Belgium. Technically, the website leverages modern web technologies including Webflow CMS, HubSpot for forms and marketing, Weglot for multilingual support, and various analytics and optimization tools such as Google Analytics, Microsoft Clarity, and Visual Website Optimizer. The site is well-optimized for performance, accessibility, and SEO, with HTTPS enforced and security best practices observed. Security posture is strong with no evident vulnerabilities, use of HTTPS, reCAPTCHA on forms, and cookie consent mechanisms. However, explicit security policies and incident response information are not published, which could be improved. WHOIS data is restricted due to DNS Belgium policies, but the domain and website content indicate legitimacy and trustworthiness. Overall, NBN's website reflects a mature digital presence with strong business credibility and security hygiene, serving a specialized market in standards and compliance. Strategic recommendations include publishing security and incident response policies, adding vulnerability disclosure mechanisms, and enhancing transparency around data protection officer contacts.

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 holds a strong market position as Belgium's national standards body, serving a diverse audience including SMEs, governments, and international companies. Their business model revolves around providing access to standards, facilitating standards development, and offering training and consulting services. Revenue streams likely include sales of standards, subscription services, training fees, and consulting. The company maintains partnerships with ISO and other standards organizations, and leverages digital platforms for service delivery. Growth indicators include a broad client base (700+ companies) and active engagement in standards development and education. The company operates primarily in the government sector with a medium-sized organizational footprint.

Security posture

The website demonstrates a good security maturity level with enforced HTTPS, use of Google reCAPTCHA on forms, and cookie consent mechanisms indicating GDPR compliance. No exposed sensitive data or vulnerable libraries were detected. However, the absence of a published security policy, incident response plan, or security.txt file suggests room for improvement in transparency and readiness. No direct contact channels for security incidents were found. Overall, the security posture is solid for a public-facing informational site but could be enhanced by formalizing and publishing security governance documents.

Recommendations

  1. Publish a dedicated security policy and incident response plan on the website.
  2. Implement and publish a security.txt file to facilitate vulnerability disclosures.
  3. Provide clear contact information for security incidents, such as security@ or abuse@ email addresses.
  4. Regularly review and update third-party scripts and dependencies to mitigate vulnerabilities.
  5. Enhance transparency around data protection officer contact details to strengthen GDPR compliance.

Technical notes

Notes

The website is built on Webflow CMS, utilizing modern JavaScript libraries and integrations such as HubSpot for forms and marketing automation, Weglot for multilingual support, and analytics tools including Google Analytics and Microsoft Clarity. Performance is moderate with good mobile optimization and accessibility features implemented. The site uses Google Tag Manager for tag management and Visual Website Optimizer for A/B testing and optimization. The technical infrastructure is modern and well-maintained, though hosting provider details are not explicitly identified. The use of multiple third-party scripts necessitates ongoing security monitoring to prevent potential risks.
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.
