Risk levelMedium

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

Commerzbank's group website serves as the corporate portal for one of Germany's major banking institutions. The site provides information about the bank's corporate identity and services, targeting corporate clients, investors, and the general public interested in the bank's operations. The website demonstrates a professional design with consistent branding and a moderate level of technical maturity, including the use of modern web technologies and a cookie consent mechanism to comply with privacy regulations. Security posture is adequate with HTTPS enforced and cookie consent implemented, but lacks visible security headers and explicit security policies. The absence of explicit privacy policy and terms of service in the provided content suggests areas for improvement in privacy compliance and transparency. Overall, the domain registration data aligns well with the business claims, indicating a legitimate and trustworthy online presence.

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

5 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • 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 Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  3. 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

Commerzbank operates in the banking sector with a focus on corporate banking and financial services. The website reflects an enterprise-level organization with a strong market position in Germany. The business model revolves around providing financial products and services to corporate clients and investors. The website's content and structure suggest a focus on professionalism and trustworthiness, although explicit contact information and detailed policy documents are not evident in the provided content. The bank likely leverages internal analytics and consent management tools to monitor user interactions and comply with GDPR requirements. The absence of visible partner or subsidiary domains in the HTML content limits insights into the broader partnership ecosystem.

Security posture

The website enforces HTTPS, ensuring encrypted communication, and implements a cookie consent mechanism, indicating awareness of privacy regulations. However, the lack of detected security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options represents a missed opportunity to enhance security posture. No vulnerability disclosures or incident response contacts are visible, which could impact the bank's ability to manage security incidents effectively. The WHOIS data is consistent and legitimate, supporting trust in the domain's authenticity. Recommendations include publishing comprehensive security policies, adding security headers, and providing clear incident response contacts to strengthen security maturity.

Recommendations

  1. Implement and publish a comprehensive privacy policy and terms of service on the website.
  2. Add standard security headers (Content-Security-Policy, X-Frame-Options, X-Content-Type-Options) to enhance protection against common web attacks.
  3. Publish a vulnerability disclosure policy or security.txt file to facilitate responsible reporting of security issues.
  4. Provide clear contact information including emails and phone numbers for customer support and security incident reporting.
  5. Enhance accessibility features and SEO metadata to improve user experience and search engine visibility.

Technical notes

Notes

The website uses standard web technologies including HTML5, CSS, and JavaScript, with deferred script loading and CSS preloading for performance optimization. The presence of a cookie consent management script indicates compliance efforts with privacy laws. The site appears mobile-optimized with responsive design elements. However, no specific CMS or hosting provider information is discernible from the provided content. Performance is moderate, with room for improvement in accessibility and SEO. The absence of visible security headers and detailed metadata suggests technical debt in security and compliance areas. Overall, the technical infrastructure supports a professional banking website but could benefit from modernization and enhanced security controls.
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.
