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

The bank holds a strong regional position in Aachen, Germany, serving both private and business clients. Its business model focuses on retail banking products such as checking accounts, credit cards, loans, and investment products, supplemented by insurance and advisory services. The presence of multiple social media channels and digital services indicates a mature digital strategy. The bank leverages partnerships for investment modules and chatbot services, enhancing customer engagement. Awards for banking excellence reinforce its competitive advantage. The website content and structure support customer acquisition and retention through clear navigation and service offerings.

Security posture

The website enforces HTTPS and uses session timeout mechanisms to protect user sessions. Cookie consent is implemented in compliance with GDPR. The use of Dynatrace monitoring indicates active performance and security monitoring. However, no explicit security policy or incident response contact information is published, which could be improved to enhance transparency and readiness. No vulnerabilities or exposed sensitive data were detected in the content. Overall, the security posture is solid for a banking website, but publishing additional security documentation would strengthen trust.

Recommendations

  1. Publish a dedicated security policy page outlining security measures and user guidance.
  2. Provide clear incident response contact channels such as security@ or abuse@ emails.
  3. Implement and publish a security.txt file to facilitate vulnerability disclosures.
  4. Enhance transparency by detailing data retention policies and cookie usage specifics.
  5. Regularly review and update third-party scripts and libraries to mitigate potential vulnerabilities.

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.
