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

M.M.Warburg & CO is a well-established independent private bank in Germany with a history dating back to 1798. The bank offers a broad range of financial services including private banking, asset management, corporate and investment banking, and institutional client services. The website targets private clients, business customers, and institutional investors, emphasizing personalized service and long-term client relationships. Technically, the website uses modern web technologies such as Apache server, UserCentrics consent management, Google Analytics, and Google Tag Manager, and is built on OpenCms. However, a critical security issue is the absence of a valid SSL certificate and HTTPS support, which severely impacts the security posture. Privacy compliance is strong with a comprehensive privacy policy and cookie consent mechanism. The website is professionally designed with consistent branding and rich content, including reports and multimedia. Overall, the site reflects a reputable financial institution but urgently needs to address its SSL/TLS configuration to ensure secure communications.

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

4 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 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 Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • 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 strong market position as an independent private bank with over two centuries of history. Its business model focuses on personalized financial solutions for private, corporate, and institutional clients. The presence of multiple branch offices across major German cities and extensive published materials indicates a mature and transparent organization. The bank leverages partnerships within the Warburg group and maintains active social media channels for outreach. The website content and structure support a professional image aimed at high-net-worth individuals and businesses. Growth indicators include a focus on sustainability and digital engagement through newsletters and multimedia content.

Security posture

The current security posture is weak due to the lack of HTTPS and valid SSL certificates, exposing users to potential interception and man-in-the-middle attacks. While security headers like HSTS and CSP are present, they are not fully enforced or effective without HTTPS. No OCSP stapling or session resumption is enabled, and TLS protocols are absent. The site uses a reputable consent management platform (UserCentrics) to handle privacy compliance, which is a positive indicator. There is no visible security policy or incident response contact information, which could be improved to enhance trust and readiness. Immediate remediation of SSL/TLS issues is critical to protect user data and maintain compliance.

Recommendations

  1. Acquire and deploy a valid SSL/TLS certificate to enable HTTPS across the entire site.
  2. Enable and enforce modern TLS protocols (TLS 1.2 or TLS 1.3) and disable insecure protocols.
  3. Configure HSTS with includeSubDomains and preload flags to enforce HTTPS usage.
  4. Implement OCSP stapling and session resumption to improve security and performance.
  5. Transition Content Security Policy from report-only to enforced mode after thorough testing.
  6. Publish a clear security policy and provide incident response contact information (e.g., security@ or abuse@ emails).
  7. Continue maintaining and enhancing privacy compliance with transparent cookie consent and data protection notices.
  8. Regularly audit third-party scripts and tracking technologies to minimize privacy risks.
  9. Improve accessibility features to enhance user experience for all visitors.
  10. Monitor and update DNSSEC and CAA records to strengthen domain security.

Technical notes

Notes

The website is hosted on an Apache server with a CMS likely OpenCms, indicated by URL paths and module names. It uses modern front-end technologies including Typekit fonts and JavaScript libraries for consent management and analytics. Google Tag Manager and Google Analytics are integrated with consent-based activation. The site is mobile responsive and well-structured with clear navigation. However, performance metrics are not provided, and the lack of HTTPS is a major technical deficiency. DNS records show standard configuration without DNSSEC or CAA enabled, which could be improved. The site uses multiple external domains for analytics, advertising, and maps, all managed with consent. Overall, the technical infrastructure is modern but requires urgent security upgrades.
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.
