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

zeb.rolfes.schierenbeck.associates gmbh is a leading European strategy, management, and IT consulting firm specializing in the financial services industry. The company offers a broad range of consulting services including transformation, regulatory compliance, and corporate education, targeting banks, insurance companies, and financial technology specialists. Their market position is strong within Europe, supported by multiple subsidiary domains and partner sites across key financial markets. The website is professionally designed with excellent content quality and clear navigation, supporting a positive user experience and strong brand consistency. Technically, the website is built on Drupal 11 with modern frameworks such as Bootstrap and integrates analytics tools like Matomo and Google Tag Manager. Accessibility features and cookie consent mechanisms are implemented, reflecting good digital maturity. However, the website suffers from critical security issues due to the absence of a valid SSL certificate and lack of HTTPS support, which significantly impacts the security posture and overall trustworthiness. Security headers are well configured, but the lack of TLS protocols and OCSP stapling are notable vulnerabilities. Privacy compliance is strong, with comprehensive privacy and cookie policies and GDPR adherence. The company maintains active social media channels and provides clear contact information, enhancing business credibility. Overall, while the business and content aspects are excellent, urgent improvements in SSL/TLS configuration are necessary to elevate the security posture and user trust.

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

3 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

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

    • 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. 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.

    • Critical

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

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

zeb operates as a specialized consultancy in the finance sector, focusing on strategic transformation and IT consulting for financial institutions. Their business model revolves around providing expert advisory services to banks, insurance companies, and fintechs, supported by a network of subsidiaries and partner sites across Europe. The company leverages digital platforms and content marketing, including podcasts, publications, and events, to engage their target audience. Their market positioning as a 'partner for change' in financial services is reinforced by a consistent brand presence and comprehensive service offerings. The presence of multiple country-specific domains indicates a broad geographic footprint and localized market strategies. The company demonstrates strong growth potential through continuous content updates and active social media engagement.

Security posture

The website's security posture is currently weak due to the absence of a valid SSL certificate and lack of HTTPS support, which are critical for secure communications and user trust. While security headers such as Content Security Policy, X-Frame-Options, and HSTS are properly configured, the lack of TLS protocol support and OCSP stapling reduces the effectiveness of these measures. No known vulnerabilities like Heartbleed or POODLE are detected, but the missing encryption exposes users to potential interception and man-in-the-middle attacks. The site uses secure cookie consent mechanisms and disables cookies in analytics to enhance privacy. Incident response and security policy pages are not found, indicating potential gaps in transparency and readiness. Immediate remediation of SSL/TLS issues is recommended to improve the security posture.

Recommendations

  1. Obtain and install a valid SSL/TLS certificate to enable HTTPS across the entire site.
  2. Enable modern TLS protocols (TLS 1.2 and TLS 1.3) and disable deprecated protocols.
  3. Implement OCSP stapling to improve certificate revocation checking performance and security.
  4. Add an incident response policy page and provide security contact channels (e.g., security@ or abuse@ emails).
  5. Maintain and regularly update security headers and conduct vulnerability assessments to detect and mitigate risks.

Technical notes

Notes

The website is built on Drupal 11 CMS with Bootstrap Barrio theme, leveraging jQuery and various JavaScript libraries for UI components and analytics integration. It uses Matomo and Google Tag Manager for analytics and tracking, with a cookie consent management system (CookiesJSR) ensuring GDPR compliance. The site includes accessibility features such as an accessibility overlay and language selectors. Performance metrics indicate no load time or resource data available, suggesting potential monitoring gaps. The site is mobile optimized with responsive design and lazy loading of images. However, the lack of SSL/TLS and HTTPS support is a significant technical risk. The DNS configuration is standard with no DNSSEC or CAA records enabled, which could be improved for enhanced security.
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.
