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

8 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 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 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 bank holds a solid market position as a niche Swiss private bank with a long history and active involvement in major financial institutions like SIX Group and the Bank for International Settlements. Its business model focuses on personalized wealth management and asset servicing for high-net-worth individuals and professional asset managers. The company leverages partnerships and affiliations to enhance service offerings. The website supports this positioning with clear service descriptions, leadership profiles, and regulatory disclosures. Growth indicators include digital presence with multilingual support and modern web technologies. The partnership ecosystem includes Swiss financial authorities and private banking associations, reinforcing legitimacy and market trust.

Security posture

The website exhibits a mature security posture with enforced HTTPS, cookie consent compliant with GDPR, and no visible exposure of sensitive data. However, explicit security policies, incident response contacts, and vulnerability disclosure mechanisms are absent, representing gaps in transparency and readiness. The use of Matomo analytics indicates a preference for privacy-conscious tracking. Security headers beyond HTTPS are not clearly implemented, suggesting room for improvement. No vulnerabilities or suspicious scripts were detected in the HTML content. Overall, the security maturity is good but could be elevated by publishing formal policies and enhancing header configurations.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, X-Content-Type-Options, and Referrer-Policy.
  2. Publish a dedicated security policy page and provide incident response contact channels such as security@ or abuse@ emails.
  3. Establish a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  4. Enhance accessibility features to meet recognized standards and improve user inclusivity.
  5. Regularly audit third-party scripts and plugins for vulnerabilities and update them promptly.

Technical notes

Notes

The website is powered by WordPress 6.8.3 with Yoast SEO and WP Rocket plugins, ensuring good SEO and performance optimization. It uses Matomo for analytics, favoring privacy over third-party trackers. The inclusion of Google Tag Manager and Google Maps API supports marketing and location services. The site is mobile optimized with responsive design and lazy loading for images. The technical stack is modern and well-maintained, with no deprecated or vulnerable libraries detected. Performance is fast, and SEO is well implemented with structured data and meta tags. Hosting provider details are not explicit but the site uses HTTPS with a valid SSL certificate. Technical risks are minimal but could be further reduced by enhancing security headers and formalizing security policies.
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.
