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

Aebin Treuhand AG is a Swiss-based small finance and business consulting firm specializing in administration and advisory services for companies and private individuals. The company positions itself as a local trusted advisor in Pratteln, Switzerland, offering core services in financial and economic matters. The website reflects a professional and consistent brand image with clear contact details and affiliations to Swiss professional organizations, enhancing trustworthiness. Technically, the website is built using modern web technologies including Statamic CMS and Tailwind CSS, with a focus on performance and accessibility. The site is mobile-optimized and SEO-friendly, with no detected tracking or cookies, indicating a strong privacy posture. The absence of forms on the main page reduces attack surface, and the use of HTTPS ensures secure communications. From a security perspective, the site demonstrates good practices such as disabling automatic detection of emails and phone numbers to prevent scraping. However, explicit security headers are not visible in the HTML content and could be improved. No vulnerability disclosure or incident response information is provided, which could be enhanced to improve security transparency. Overall, the website is safe, professional, and trustworthy with a strong privacy focus. Strategic recommendations include adding explicit security headers, publishing a security policy and incident response contacts, and implementing a cookie consent mechanism if cookies are introduced in the future.

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 Strict-Transport-Security header

      Forces HTTPS connections

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

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • 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 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

  3. 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

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 finance sector as a treuhand and consulting service provider targeting both businesses and private clients in Switzerland. Its business model centers on advisory and administrative services related to financial and economic issues. The website's content and affiliations suggest a stable local market position with a focus on trust and professionalism. Revenue streams likely derive from consulting fees and administrative services. The absence of social media and limited digital marketing tools indicates a traditional or low-scale digital marketing approach. Partnerships with Swiss professional organizations enhance credibility and may provide referral opportunities. Growth indicators are not explicit but the website quality and affiliations suggest a mature small business with potential for steady local growth.

Security posture

The website exhibits a moderate to good security maturity level. HTTPS is enforced, and privacy is respected by not using cookies or tracking. The site avoids exposing emails and phone numbers to automated detection. However, the lack of visible security headers such as Content Security Policy, HSTS, or X-Frame-Options is a gap. No incident response or vulnerability disclosure information is provided, which limits transparency and preparedness. No known vulnerabilities or exposed sensitive data were detected in the content. Compliance with GDPR is implied by the presence of a privacy policy and cookie statement, though no explicit cookie consent mechanism is implemented. Overall, the security posture is adequate for a small business but could be improved with additional policies and technical controls.

Recommendations

  1. Implement and publish explicit security headers including Content Security Policy, HSTS, and X-Frame-Options.
  2. Add an incident response contact email or page to improve security transparency and readiness.
  3. Consider introducing a cookie consent mechanism if any cookies or tracking are added in the future.
  4. Publish a dedicated security policy page outlining security practices and compliance.
  5. Enhance digital marketing presence with social media links and analytics while maintaining privacy compliance.

Technical notes

Notes

The website uses a modern technology stack with Statamic CMS and Tailwind CSS, leveraging JavaScript ES modules and Typekit fonts for styling and typography. The site is well-structured with semantic HTML and accessibility features such as skip links and focus-visible outlines. Performance is moderate with preloading of CSS and module scripts. The site is mobile responsive and SEO optimized with proper meta tags and Open Graph data. No broken elements or errors were detected in the HTML content. Hosting provider details are not explicit but the domain uses HTTPS with a valid certificate. There is no evidence of technical debt or outdated libraries. Opportunities exist to improve security headers and add structured data for enhanced SEO and rich results.
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.
