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

4 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 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

      SSL Certificate Expires Soon

      SSL certificate expires in 28 days

      What to do: Renew SSL certificate before expiration

      • NIS2 21(2)(h)
      • IR 2024/2690 9.2(c): Implementing Regulation (EU) 2024/2690, Annex point 9.2(c): Cryptography
      • NIST SC-17: NIST SP 800-53 Rev. 5 SC-17: Public Key Infrastructure Certificates

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 operates in the media sector as a small-sized creative agency offering branding, web development, applications, and content creation services. Their market positioning is focused on local and regional clients seeking bespoke creative solutions. The business model revolves around service provision with a strong emphasis on digital presence and brand visibility. The website content and structure indicate a professional approach with clear service descriptions and case studies. The use of modern web technologies and analytics tools suggests a digitally mature operation. Social media presence on Instagram, LinkedIn, and Facebook supports marketing and client engagement efforts. No parent or subsidiary companies are identified, indicating an independent operation.

Security posture

The website employs HTTPS with a valid SSL certificate, ensuring encrypted communications. Cookie consent is managed via Cookiebot, providing GDPR-compliant user consent mechanisms. No security headers were detected in the provided data, which is a potential area for improvement. The domain lacks DNSSEC, which could enhance DNS security. No exposed sensitive data or vulnerable libraries were identified. Third-party scripts include Google Analytics, Fathom Analytics, Leadinfo, and Cookiebot, all managed with user consent. Incident response and security policy information are not publicly available. Overall, the security posture is good but could be strengthened by implementing security headers and DNSSEC.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  2. Implement security headers such as Content-Security-Policy, Strict-Transport-Security, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  3. Regularly audit and update third-party scripts and libraries to mitigate vulnerabilities.
  4. Publish explicit security policy and incident response information to improve transparency and trust.
  5. Enhance accessibility features to improve compliance and user experience for all visitors.

Technical notes

Notes

The website is built using Next.js and React, indicating a modern and scalable frontend framework. Hosting is provided by mijn.host, a known hosting provider. The site uses Cookiebot for cookie consent management, Google Tag Manager for tag management, and analytics tools including Fathom Analytics and Leadinfo. The site is mobile optimized with responsive design and good SEO practices including meta tags and structured data. Performance is moderate, with preloading of critical assets and optimized images. Accessibility is basic but could be improved. No CMS is detected, suggesting a custom or headless approach. Overall, the technical infrastructure is solid with room for security and accessibility enhancements.
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.
