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"

  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
    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

Comerica Bank operates in the finance sector with a focus on banking and wealth management services. It holds a strong market position as a recognized regional bank with awards for small business banking excellence. The business model centers on relationship banking, serving consumers, small businesses, and commercial clients. Revenue streams likely include deposit accounts, loans, credit cards, investment advisory, and wealth management fees. The company is in the process of merging with Fifth Third, indicating strategic growth. The website ecosystem includes partner and subsidiary domains supporting various banking platforms. The company maintains a professional brand image and leverages digital marketing and analytics tools to engage customers and optimize services.

Security posture

The website exhibits a strong security posture with HTTPS enforced site-wide and secure login forms for multiple banking services. No exposed sensitive data or vulnerable libraries were detected in the HTML content. The use of modern tracking and analytics scripts is balanced with privacy compliance measures. However, explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options are not clearly visible and should be verified. There is no public vulnerability disclosure or incident response contact information, which could be improved to enhance transparency and readiness. Overall, the site follows best practices for a financial institution but could benefit from enhanced security header implementation and public security policies.

Recommendations

  1. Implement and clearly document all recommended security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  2. Establish and publicize a formal vulnerability disclosure policy and incident response contact channels to improve transparency and security culture.
  3. Regularly audit third-party scripts and libraries to ensure no vulnerabilities or outdated components are present.
  4. Enhance user awareness of privacy and security practices through visible notices and educational content.
  5. Continue to optimize site performance and accessibility to maintain excellent user experience across all devices.

Technical notes

Notes

The website is built on Adobe Experience Manager (AEM), a robust enterprise CMS platform suitable for large financial institutions. It uses a modern tech stack including jQuery, Google Tag Manager, Facebook Pixel, LinkedIn Insight Tag, and Vimeo for video content. The site is mobile-optimized with responsive design and accessibility features. Performance is moderate with some third-party scripts that may impact load times but overall provides a smooth user experience. SEO is well addressed with proper meta tags, Open Graph, and Twitter cards. Technical risks are low, but continuous monitoring of third-party dependencies is recommended 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.
