0–100, higher is better. How it is calculated

M.M.Warburg & CO operates a professional online banking platform targeting banking customers primarily in Germany. The website offers secure login mechanisms including electronic TAN authentication and provides clear customer support phone contacts. The technical infrastructure is based on AngularJS with custom JavaScript and CSS, delivering a good user experience and mobile optimization. However, the absence of a valid SSL certificate and lack of modern TLS protocols represent critical security vulnerabilities that undermine trust and data protection. Security headers are well implemented, but the SSL/TLS configuration requires urgent remediation. Privacy compliance is strong with a clear cookie consent mechanism and a comprehensive privacy policy. Overall, the website is functional and professional but needs immediate security improvements to meet industry standards.

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.

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 positions itself as a private banking institution with a focus on secure online banking services. Its business model revolves around providing digital banking access to clients with enhanced security via electronic TAN devices. The target audience includes retail and private banking customers in Germany. The website content and structure reflect a consistent brand identity and trust signals such as privacy policies and secure login prompts. No public information about certifications or incident response is available, which could be improved to enhance credibility. The domain registration aligns with the business claims, supporting legitimacy.

Security posture

The current security posture shows a mix of strengths and critical weaknesses. Security headers such as CSP, HSTS, X-Frame-Options, and X-XSS-Protection are properly configured, indicating awareness of web security best practices. However, the lack of a valid SSL certificate and disabled TLS protocols are severe issues that expose users to potential interception and man-in-the-middle attacks. The absence of OCSP stapling and session resumption further reduces security and performance. No public incident response or vulnerability disclosure policies are found, limiting transparency. Immediate action is required to obtain and configure valid SSL/TLS certificates and enable modern protocols to protect user data and maintain trust.

Recommendations

  1. Acquire and deploy a valid SSL/TLS certificate supporting TLS 1.2 and TLS 1.3 protocols.
  2. Enable and properly configure HSTS with includeSubDomains and preload flags.
  3. Implement OCSP stapling and session resumption to improve security and performance.
  4. Publish a public security policy and incident response contact information to enhance transparency.
  5. Review and restrict use of unsafe inline scripts and styles in the Content Security Policy.
  6. Add explicit contact emails for security and incident reporting purposes.
  7. Enable DNSSEC and CAA records to strengthen domain security posture.
Technical notes

Notes

The website uses AngularJS framework and custom JavaScript for frontend functionality, including dynamic TAN input forms and modals. CSS is used for styling with responsive design elements. The site includes a cookie consent modal and privacy policy link. Performance data is unavailable, but the site appears to have moderate complexity. No CMS or hosting provider information is detected. The SSL/TLS configuration is currently non-functional, which is a major technical risk. The site uses secure cookies with HttpOnly and SameSite flags. No analytics or advertising scripts are detected, indicating minimal tracking. Overall, the technical implementation is solid but requires urgent SSL/TLS remediation and modernization.
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.
