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.

Priority findings

5 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.

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • 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

  2. 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"

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

DZ BANK holds a strong market position as a central institution for cooperative banks and offers a wide range of financial services including corporate banking, institutional client services, private banking, and investment research. The company operates globally with multiple subsidiaries and partner companies, emphasizing sustainability and compliance. The website's extensive content and structured navigation reflect a well-established business model focused on innovation, customer proximity, and regulatory adherence. The presence of a bug bounty program and detailed compliance pages indicates a proactive security culture. DZ BANK's ecosystem includes several subsidiaries and partner sites, enhancing its service portfolio and market reach.

Security posture

The website employs robust security measures including HTTPS with modern TLS protocols (TLS 1.3 and 1.2), HSTS with subdomain inclusion, and comprehensive SPF and DMARC DNS records to protect email integrity. No critical vulnerabilities such as Heartbleed or FREAK were detected. However, OCSP stapling is not enabled, and the CAA DNS records appear misconfigured, which could impact certificate issuance security. The site uses a bug bounty program to encourage vulnerability reporting. Overall, the security posture is strong but can be enhanced by addressing minor configuration issues and enabling certificate transparency compliance.

Recommendations

  1. Enable OCSP stapling on the web server to improve certificate revocation checking and reduce latency.
  2. Correct the CAA DNS records to explicitly specify authorized certificate authorities to prevent unauthorized certificate issuance.
  3. Implement certificate transparency compliance to enhance trust and detect fraudulent certificates.
  4. Regularly audit and update third-party scripts and libraries to mitigate potential vulnerabilities.
  5. Maintain and promote the bug bounty program to continuously improve security posture and incident response.

Technical notes

Notes

The website is built on Adobe Experience Manager CMS, indicating a robust enterprise-grade content management system. It uses modern JavaScript frameworks such as Hyperapp for navigation and integrates Matomo and Google Tag Manager for analytics. User consent is managed via Usercentrics, reflecting GDPR compliance. Hosting is on Google Cloud infrastructure. Performance is suboptimal with a high page size (~5MB) and long load time (~31 seconds), suggesting opportunities for optimization. The site is mobile-optimized and accessible with good SEO practices. Technical risks include slow loading times and minor DNS misconfigurations that could affect security and user experience.
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.
