Zebralog is a German-based company specializing in designing, consulting, and supporting participatory projects both digitally and on-site. Their core offering includes a digital participation platform called Dialogzentrale, alongside consulting services for public involvement, customer participation, and employee dialogues. The company targets organizations and entities seeking effective participatory approaches. Technically, the website is built on Drupal 10, employs Matomo Analytics with privacy-respecting configurations, and uses modern web technologies including Font Awesome and CookiesJSR for cookie management. The site is hosted on Gandi nameservers and demonstrates good mobile optimization, accessibility, and SEO practices. Security posture is solid with HTTPS enforced and privacy compliance evident through comprehensive cookie consent and privacy policies. However, some security headers could be improved, and no explicit security or incident response policies are published. Overall, the website is professional, trustworthy, and compliant with GDPR, making it a reliable digital presence for Zebralog.

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 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 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. 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

Zebralog occupies a niche market position as a service provider focused on participatory processes and digital engagement platforms. Their business model revolves around consulting and software solutions for public and organizational participation. The company maintains a small size with a clear focus on government, non-profit, and related sectors. Their digital maturity is evidenced by the use of open-source analytics and a modern CMS. The presence of social media channels and a newsletter indicates active engagement with their audience. No parent or subsidiary companies were identified. The company demonstrates a consistent brand and trustworthy online presence, supported by GDPR-compliant policies and transparent cookie management.

Security posture

The website exhibits a mature security posture with HTTPS enabled and respect for user privacy through cookie consent and Do Not Track compliance in Matomo Analytics. Antibot measures protect forms from spam. However, the absence of additional security headers such as Content-Security-Policy and lack of published security or incident response policies represent areas for improvement. No vulnerabilities or exposed sensitive data were detected in the provided content. The security score is high but could be enhanced by adopting more comprehensive security best practices and publishing incident response contacts.

Recommendations

  1. Implement additional HTTP security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Publish a formal security policy and incident response contact information to improve transparency and readiness.
  3. Consider adding a vulnerability disclosure policy or security.txt file to facilitate responsible reporting of security issues.
  4. Regularly audit third-party scripts and libraries to ensure no vulnerabilities are introduced.
  5. Enhance contact information by including a physical address and verified company emails to strengthen business credibility.

Technical notes

Notes

The website is built on Drupal 10, a modern and widely used CMS, indicating a solid technical foundation. It uses Matomo Analytics for privacy-conscious user tracking and CookiesJSR for cookie consent management. The site loads CSS and JavaScript assets efficiently and includes accessibility features such as skip links and ARIA attributes. Hosting is managed via Gandi nameservers, a reputable provider. Performance is moderate with good mobile optimization and SEO practices. The technical stack is modern and well-maintained, though opportunities exist to improve security headers and formalize security documentation.
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.
