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

8 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 Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

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

BBN operates as a membership-based expert organization in the fire safety sector, targeting construction professionals and companies in the Netherlands. Its business model revolves around providing training, checklists, whitepapers, and webinars to members and the wider industry. The website showcases a network of partners and suppliers, indicating a collaborative ecosystem. Revenue likely derives from membership fees, training registrations, and possibly consultancy. The company maintains a consistent brand and professional online presence, reinforcing trust and authority in its niche market. Growth indicators include regular news updates and training offerings aligned with evolving fire safety standards.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, use of Google reCAPTCHA on forms to prevent spam, and no visible exposure of sensitive data. However, the lack of security headers such as Content-Security-Policy and Strict-Transport-Security is a gap that could be exploited. No incident response or security policy information is published, which limits transparency and preparedness perception. The missing WHOIS data for the domain is a notable anomaly that could indicate registration issues or privacy protection, impacting trust. Overall, the site is secure for general use but would benefit from enhanced security controls and published policies to improve compliance and user trust.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Content-Type-Options, and Strict-Transport-Security to harden the website.
  2. Add a cookie consent banner and detailed cookie policy to comply fully with EU GDPR and ePrivacy regulations.
  3. Publish a clear security policy and incident response contact details to improve transparency and preparedness.
  4. Investigate and resolve the missing WHOIS registration data to ensure domain legitimacy and trustworthiness.
  5. Enhance accessibility features to meet WCAG standards and improve user experience for all visitors.

Technical notes

Notes

The website is powered by WordPress CMS using a custom theme (fuze-2.0) and leverages modern front-end libraries such as jQuery, Swiper.js, and FontAwesome. Google Fonts are used for typography. Analytics and user behavior tracking are implemented via Google Analytics, Google Tag Manager, and Hotjar. The site uses Google reCAPTCHA v2 for form spam protection. Performance is moderate with responsive design and mobile optimization evident. SEO is supported by proper meta tags and Open Graph data. No major technical debt or outdated libraries were detected. Hosting provider details are not disclosed. Overall, the technical infrastructure is solid but could benefit from improved security header implementation and cookie consent mechanisms.
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.
