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

5 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 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 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. 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

      What to do: Implement a cookie consent banner that appears on first visit

  3. 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 Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1
    • 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

Domeinenbank holds a strong market position as a long-established domain specialist in the Netherlands. Its business model revolves around domain brokerage and related services, catering to a niche but essential segment of the technology sector. The company leverages testimonials and premium domain listings to build trust and attract customers. The absence of direct contact emails or phone numbers suggests a preference for controlled communication via contact forms. The website's SEO and content strategy focus on domain-related keywords, supporting organic growth. No evident partnerships or subsidiaries were identified from the data.

Security posture

The website demonstrates a good security baseline with HTTPS enforced and DNSSEC enabled, reducing risks of interception and DNS spoofing. However, the lack of explicit security headers such as Content-Security-Policy and absence of a security.txt file indicate room for improvement in security maturity. No vulnerabilities or exposed sensitive data were detected in the HTML content. Privacy compliance is addressed through detailed policies, but cookie consent mechanisms are missing, which could be a compliance risk under GDPR. Incident response and security contact channels are not published, limiting transparency in security management.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to enhance protection against common web attacks.
  2. Publish a security.txt file to facilitate responsible vulnerability disclosure and improve security transparency.
  3. Add a cookie consent banner or mechanism to ensure explicit user consent for tracking cookies, enhancing GDPR compliance.
  4. Provide clear incident response policies and dedicated security contact channels (e.g., security@ or abuse@ emails) to improve trust and readiness.
  5. Regularly audit third-party scripts and plugins to ensure no vulnerable libraries are in use and maintain updated software versions.

Technical notes

Notes

The website is built on WordPress CMS with Elementor page builder and Yoast SEO plugin, indicating a modern and flexible content management system. It uses Google Fonts, jQuery, and Google Analytics with MonsterInsights for tracking. Performance is moderate with good mobile optimization and basic accessibility features. The site uses DNSSEC and HTTPS with SSL, ensuring secure communications. However, some technical debt is evident in missing advanced security headers and lack of explicit cookie consent mechanisms. The site structure and metadata are well-formed, supporting SEO and social sharing. Hosting provider details are not explicitly identified from the content.
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.
