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

2 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.

    • 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

  2. 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

American Express Switzerland targets affluent private and business customers seeking premium credit card products with travel and lifestyle benefits. The business model centers on credit card issuance, rewards programs, and associated financial services. The partnership with Swisscard AECS GmbH enables localized card issuance and customer service. The website's extensive navigation and content reflect a broad product portfolio including consumer, business, and corporate cards. The company leverages strong brand equity and digital marketing tools to maintain competitive advantage. Social media engagement on Facebook and Instagram supports brand visibility. The absence of direct contact emails or phone numbers on the main site suggests reliance on Swisscard's infrastructure for customer interactions.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, presence of key security headers, and a cookie consent mechanism aligned with GDPR requirements. Use of reputable analytics and tag management platforms is evident, with no exposed sensitive data or vulnerable libraries detected in the HTML content. However, the lack of a publicly accessible security policy, incident response information, or vulnerability disclosure program represents an area for improvement. No suspicious or malicious indicators were found. The domain registration details align with the business identity, further supporting legitimacy. Overall, the site is secure but could enhance transparency and readiness by publishing explicit security and incident response information.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and compliance.
  2. Implement and publicize a vulnerability disclosure program or security.txt file.
  3. Provide direct security incident contact channels such as security@ or abuse@ emails.
  4. Regularly review and audit third-party scripts and analytics tools for security risks.
  5. Enhance transparency on data retention and privacy practices to strengthen user trust.

Technical notes

Notes

The website is built on a modern technology stack including React for frontend rendering, Adobe Dynamic Tag Manager for marketing and analytics integration, and Piano Analytics alongside Matomo Tag Manager for user behavior tracking. Fonts are served via Adobe Typekit. The site likely uses an enterprise CMS such as Adobe Experience Manager, indicated by structured content and asset management patterns. Performance is optimized with lazy loading of images and preconnect/dns-prefetch hints. Accessibility features such as skip links and ARIA roles are implemented, supporting compliance with accessibility standards. SEO is supported by comprehensive meta tags, Open Graph, and JSON-LD structured data. Hosting appears to be managed by Swisscard AECS GmbH or a trusted partner. Overall, the technical infrastructure is robust, scalable, and aligned with enterprise-grade digital standards.
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.
