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

    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';…

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.

Add-on

Leaked records that mention mathiaskrebser.de, from OffSeq Breach.

No leaked records found

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 digital portfolio and marketing channel for Mathias Krebser's creative services. The presence of a linked external shop suggests monetization through art sales or commissions. The use of modern web technologies and Cloudflare DNS indicates a moderate level of digital maturity. The target customer segment likely includes art enthusiasts, potential clients for design/video/illustration projects, and online shoppers of creative products. No explicit partnerships or subsidiaries are indicated.

Security posture

The website benefits from HTTPS encryption and uses Cloudflare DNS, providing a solid baseline for security. However, the absence of security headers and lack of privacy or cookie policies indicate gaps in security best practices and compliance. No forms or input fields reduce attack surface, but the site lacks incident response contact information and vulnerability disclosure mechanisms. Tracking is minimal and privacy-focused via Plausible Analytics. Overall, the security posture is moderate but could be improved with additional policies and headers.

Recommendations

  1. Implement and publish a privacy policy and cookie policy to improve GDPR compliance and user trust.
  2. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  3. Provide clear contact information including an email address for general and security-related inquiries.
  4. Consider adding a vulnerability disclosure policy or security.txt file to facilitate responsible reporting of security issues.
  5. Enhance accessibility features to improve usability for all users and comply with accessibility standards.

Technical notes

Notes

The website is built using the Svelte JavaScript framework, leveraging modern module preloading and a custom or proprietary CMS for asset management. Hosting and DNS are managed via Cloudflare, providing performance and security benefits. The site loads multiple JavaScript chunks and CSS assets efficiently, with responsive design and mobile optimization evident. SEO is supported by proper meta tags and structured data (JSON-LD). No major technical debt or outdated technologies detected, though security headers are missing and accessibility could be improved.
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.
