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

Carl Barenbrug's website serves as a professional portfolio showcasing his work as a product designer and creative director. The site highlights his involvement with various creative projects and companies, including Minimalissimo and 099. The business model is centered on creative services and personal branding within the design industry. The website is well-structured with good design quality and clear navigation, targeting design professionals and enthusiasts. Technically, the site uses modern web standards with custom fonts and JavaScript, hosted on Hover's DNS infrastructure. Performance and mobile optimization are adequate, though accessibility could be improved. Security posture is moderate; domain registration protections are in place but DNSSEC is not enabled and security headers are missing. Privacy compliance is lacking due to absence of privacy and cookie policies. Overall, the site is trustworthy but could benefit from enhanced security and compliance measures.

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

6 findings rated critical or high. Fix these first.

  1. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  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 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 Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • 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

    • 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

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 website positions Carl Barenbrug as a niche creative professional with a small-scale operation focused on product design and creative direction. His partnerships and projects indicate a collaborative ecosystem with other creative entities. The business model relies on showcasing expertise and attracting potential clients or collaborators. The absence of commercial elements like e-commerce or advertising suggests a focus on reputation and professional presence. Growth potential is tied to the creative industry's demand for design leadership. The external domains linked are relevant partners and projects, reinforcing the professional network. No direct revenue streams or monetization methods are evident from the site content.

Security posture

The security maturity level is moderate. The domain is registered with protections against unauthorized transfers and updates, which is positive. However, DNSSEC is not enabled, which could expose DNS spoofing risks. No security headers such as Content-Security-Policy or Strict-Transport-Security were detected, which are recommended best practices. The site uses HTTPS as indicated by canonical URLs, but SSL configuration details are unknown. No forms or data collection points reduce attack surface, but also limit user engagement. There is no evidence of incident response or vulnerability disclosure policies, which could be improved to enhance security culture and readiness. Overall, the site is low risk but could strengthen defenses and compliance.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  2. Implement standard security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Publish a comprehensive privacy policy and cookie policy to improve GDPR and privacy compliance.
  4. Consider adding a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  5. Enhance accessibility features to improve inclusivity and compliance with standards.

Technical notes

Notes

The website is built with clean, modern HTML5 and CSS3, using custom variable fonts and a minimalist design approach. JavaScript is used minimally for UI enhancements. The site is hosted with Hover DNS services, indicating a standard hosting setup. Performance is moderate with no heavy scripts or external dependencies detected. SEO is supported with meta tags, canonical links, and RSS feed. Mobile optimization is good with responsive design and viewport settings. Accessibility is basic but could be improved with ARIA roles and better semantic markup. No CMS or frameworks detected, suggesting a custom or static site. Technical risks are low but modernization opportunities exist in security and accessibility.
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.
