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 targets private individuals, youth, students, and corporate clients within its regional market. It leverages a multi-channel approach including online account opening, digital banking portals, and investment advisory services. The presence of certifications such as ISO 27001 and awards like Great Place to Work indicate a focus on quality and trust. The bank maintains partnerships and subsidiary services accessible via related domains, enhancing its service ecosystem.

Security posture

The website employs HTTPS with strong SSL configuration and implements multiple security headers, indicating a robust security posture. Forms are protected with anti-forgery tokens and no sensitive data is exposed in the HTML. However, explicit incident response and vulnerability disclosure policies are not publicly visible, representing an area for improvement. The use of third-party analytics is compliant with privacy standards, and cookie consent mechanisms are in place.

Recommendations

  1. Publish a dedicated incident response and vulnerability disclosure policy to enhance transparency and trust.
  2. Implement and publish a security.txt file to facilitate responsible vulnerability reporting.
  3. Make data protection officer contact information more visible to comply with GDPR best practices.
  4. Regularly review and update third-party scripts and analytics tools to mitigate potential security risks.
  5. Consider advanced WAF and bot management solutions to proactively defend against emerging threats.

Technical notes

Notes

The website is built on Microsoft SharePoint with ASP.NET Web Forms, leveraging modern JavaScript libraries like jQuery and RequireJS. It shows good mobile optimization and accessibility features. Performance is moderate, likely due to the complexity of SharePoint infrastructure. SEO is well addressed with proper meta tags and Open Graph data. Hosting appears to be managed internally or via Swiss providers, ensuring data sovereignty. Opportunities exist to modernize front-end frameworks and optimize load times further.
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.
