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

Christina Mäckelburg's website is a professional portfolio showcasing her work as an illustrator and animator specializing in children's books. The site targets a general audience interested in artistic and creative services, positioning itself as a niche personal brand in the illustration industry. The business model is primarily portfolio-based, aimed at attracting clients or collaborators. Technically, the website employs modern web standards including ES modules, CSS, and video content, hosted behind Cloudflare DNS services. The site is mobile optimized with good SEO practices but lacks some accessibility features and security headers. Performance is moderate with a clean and visually appealing design. From a security perspective, the site uses HTTPS with a good SSL configuration and does not expose sensitive data or contain forms that collect user input. However, it lacks security headers and formal privacy or cookie policies, which are important for compliance and trust. Minimal user tracking is done via Plausible Analytics, which respects privacy better than many alternatives. Overall, the website presents a low-risk profile with good professionalism but could improve privacy compliance and security posture. Strategic recommendations include adding privacy and cookie policies, implementing security headers, and enhancing contact options to improve user trust and regulatory compliance.

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

7 findings rated critical or high. Fix these first.

  1. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • 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

  2. Security headers

    • High

      Missing Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

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 serves as a personal portfolio for an illustrator based in Stuttgart, Germany, focusing on children's book illustrations and animations. The business operates in a niche creative sector with a small scale and no indication of subsidiaries or parent companies. Revenue likely derives from commissioned artwork and collaborations. The target customers are publishers, authors, and creative agencies seeking illustration services. The site does not indicate partnerships or extensive business ecosystems but maintains a consistent brand image. Growth indicators are not explicit but the professional presentation suggests an established presence in the niche market.

Security posture

The security maturity level is moderate. The site benefits from HTTPS and Cloudflare DNS, ensuring encrypted communications and some protection against DNS attacks. No forms or user input reduce attack surface. However, the absence of security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options is a gap that could expose the site to clickjacking or MIME sniffing attacks. No privacy or cookie policies are present, which is a compliance gap under GDPR. Incident response and vulnerability disclosure mechanisms are not found, indicating limited readiness for security incidents. Overall, the site is low risk but could improve security hygiene and compliance.

Recommendations

  1. Implement a comprehensive privacy policy and cookie policy to ensure GDPR compliance and user trust.
  2. Add security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  3. Consider adding a secure contact form with input validation to facilitate client communication while protecting data.
  4. Establish an incident response contact channel such as security@ or abuse@ email addresses to improve security readiness.
  5. Regularly review and update analytics and tracking tools to maintain minimal user tracking and privacy compliance.

Technical notes

Notes

The website uses modern front-end technologies including JavaScript ES modules and CSS with video integration for rich media content. Hosting is supported by Cloudflare DNS, likely providing CDN and DDoS protection. The site is mobile optimized and SEO friendly with proper meta tags and Open Graph data. However, no CMS or backend platform is detected, suggesting a static or JAMstack architecture. Performance is moderate with no broken elements. Accessibility is basic and could be enhanced with ARIA attributes and better keyboard navigation support. The lack of security headers is a technical debt that should be addressed to reduce risk.
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.
