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

Greenbone AG is a German-based cybersecurity company specializing in open source vulnerability management solutions that comply with GDPR. Their offerings include automated and customizable vulnerability scanning products such as OPENVAS SCAN and Greenbone Cloud Service, targeting IT security professionals across sectors including public, healthcare, and education. The company positions itself as a trusted provider with a strong emphasis on compliance and automation. Technically, the website is built on WordPress using a professional theme and SEO plugins, with modern analytics tools like Matomo and Google Tag Manager implemented. The site is mobile-optimized and accessible, reflecting a mature digital presence. Security-wise, the site enforces HTTPS and uses security hardening plugins, though some security headers could be improved and explicit incident response information is lacking. The WHOIS data is not publicly available, which reduces transparency but may be justified for privacy reasons. Overall, the website is professional, trustworthy, and well-structured, with room for improvement in domain transparency and security disclosures.

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. 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 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 Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

  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

Greenbone AG operates in the competitive cybersecurity market with a focus on open source vulnerability management. Their business model revolves around software products, cloud services, and support/training offerings. The company targets enterprise customers and public sector organizations requiring compliance with data protection regulations. Their multilingual website and professional content indicate a strategic approach to international markets. Partnerships, such as with Severn Consultancy GmbH, enhance their market reach. The company demonstrates growth potential through continuous product innovation (e.g., OPENVAS AI) and educational initiatives. Revenue streams likely include product licenses, cloud subscriptions, and professional services. The absence of detailed WHOIS data suggests a cautious approach to privacy, common in security-focused firms.

Security posture

The website demonstrates a solid security posture with HTTPS enforced and use of security hardening plugins. No sensitive data leakage or vulnerable libraries were detected in the HTML content. However, the absence of comprehensive security headers like Content-Security-Policy and explicit incident response or vulnerability disclosure pages indicates areas for enhancement. The cookie consent mechanism and GDPR compliance are positive indicators. The lack of DNSSEC information and missing WHOIS transparency slightly reduce trust. Overall, the security maturity is good but could benefit from formalized incident response documentation and improved header configurations.

Recommendations

  1. Implement full security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Publish a dedicated incident response and vulnerability disclosure page to improve transparency and trust with security researchers and customers.
  3. Verify and publish domain registration details or use a trusted registrar to improve WHOIS transparency and reduce suspicion.
  4. Enable DNSSEC for the domain to strengthen DNS security and prevent spoofing.
  5. Regularly audit third-party scripts and plugins to ensure no vulnerabilities are introduced through dependencies.

Technical notes

Notes

The website is built on WordPress CMS using the Enfold theme and Avia framework, supported by plugins such as Yoast SEO, SVG Support, WP User Avatar, and a security hardening plugin. Analytics are handled via Matomo and Google Tag Manager, indicating a mature approach to data collection and marketing. The site is mobile-optimized with responsive design and accessibility considerations. Performance is moderate, with potential improvements in script loading and caching. The technical stack is modern and well-maintained, though some security header implementations are missing. The site uses multilingual support for German, English, Italian, and Dutch, broadening its audience reach.
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.
