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

1 finding rated critical or high. Fix these first.

  1. 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 bank operates in the finance sector with a focus on private customers, offering comprehensive banking and investment services. The website's navigation and content structure support customer engagement and service discovery. The presence of subdomains for onboarding and market information indicates a diversified digital ecosystem. The absence of explicit privacy and security policies on the analyzed page suggests areas for improvement in compliance transparency. The bank's market position as a cantonal bank is supported by consistent WHOIS data and domain legitimacy.

Security posture

The website enforces HTTPS and uses a cookie consent banner, indicating awareness of privacy and security requirements. However, the lack of security headers such as Content-Security-Policy and absence of published incident response or vulnerability disclosure policies limit the security maturity. No vulnerabilities or exposed sensitive data were detected in the provided content. The security score is moderate, with recommendations to enhance header implementation and publish security policies to improve trust and compliance.

Recommendations

  1. Publish a clear and accessible privacy policy and terms of service on the website.
  2. Implement and configure security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Provide a publicly accessible security policy or security.txt file with incident response contact details.
  4. Enhance transparency on data protection officer contact information and GDPR compliance.
  5. Regularly audit and update third-party scripts and cookie consent configurations to maintain privacy compliance.

Technical notes

Notes

The website uses standard web technologies including HTML5, CSS, JavaScript, and SVG graphics. It integrates OneTrust for cookie consent management, indicating compliance with EU privacy regulations. The site appears mobile-optimized and accessible with skip links and ARIA roles. Performance is moderate with no explicit indicators of slow loading. No CMS or hosting provider information was detected from the provided data. The technical implementation is solid but could benefit from enhanced security headers and explicit metadata for structured data and SEO.
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.
