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

The website stefan-aufdermaur.ch serves as a personal or professional portfolio site for Stefan Auf der Maur, likely showcasing artistic or photographic work. The site is minimalistic with limited metadata and no structured data, focusing primarily on visual content. The target audience appears to be general visitors interested in the individual's work, with no commercial or transactional features evident. Technically, the site uses basic HTML, CSS, and JavaScript with lazy loading for images, but lacks advanced SEO, accessibility, and performance optimizations. Security posture is weak, with no visible security headers or privacy policies, and no HTTPS status confirmed from the provided data. No contact information or forms are present, limiting user engagement and trust signals. Overall, the site is functional but basic, with room for significant improvements in security, privacy compliance, and user experience.

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. 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. 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 represents a small-scale personal brand or portfolio without clear commercial activities or business model details. There are no indications of partnerships, subsidiaries, or certifications. The absence of contact details and policies suggests a low level of business maturity and digital marketing integration. The site likely serves as an online presence for an individual professional or artist based in Switzerland. Growth potential may be limited without enhanced digital marketing, analytics, and trust-building features.

Security posture

The security posture is minimal. No security headers or HTTPS confirmation were found in the HTML content. There are no privacy or cookie policies, no incident response contacts, and no vulnerability disclosure mechanisms. The lack of these elements indicates a low maturity level in security and compliance. While no explicit vulnerabilities or malware were detected, the site would benefit from implementing standard security best practices, including HTTPS, security headers, and privacy compliance measures to protect visitors and improve trust.

Recommendations

  1. Implement HTTPS with a valid SSL certificate to secure data transmission.
  2. Add standard security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Publish clear privacy and cookie policies to comply with GDPR and build user trust.
  4. Include contact information and a security incident response channel (e.g., security@ email).
  5. Enhance mobile optimization and accessibility to improve user experience and SEO.

Technical notes

Notes

The website uses a simple technology stack with HTML5, CSS, and JavaScript, including lazy loading for images. There is no evidence of a CMS or advanced frameworks. Performance appears moderate but could be improved with better optimization and caching strategies. SEO is basic with minimal meta tags and no structured data. Accessibility features are minimal, and no ARIA roles or landmarks were detected. The site is likely self-hosted or hosted on a basic provider, but no hosting details are available. Technical debt is low due to simplicity but modernization opportunities exist to improve security, SEO, and user experience.
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.
