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

Greentube GmbH, a division of NOVOMATIC, is a leading full-service provider in the online and mobile gaming sector, delivering secure and innovative casino entertainment solutions globally. The company targets B2B clients, offering a broad portfolio including slot games, table games, video poker, and server-based gaming platforms. Their market position is strong, supported by a comprehensive product suite and certifications such as ISO 27001. Technically, the website is built on WordPress with modern JavaScript libraries and frameworks, optimized for mobile and SEO, and integrates analytics and consent management tools. Security posture is robust with HTTPS, security headers, and cookie consent, though explicit security policies and incident response details are not publicly available. Overall, the website is professional, trustworthy, and compliant with privacy regulations, though the lack of WHOIS data slightly impacts domain trust. Strategic recommendations include publishing security policies, vulnerability disclosure, and providing direct security contacts to enhance trust and compliance.

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

6 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"

    • 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

    • 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. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

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

Greentube operates in the technology sector focused on digital gaming and entertainment, serving a global B2B audience. Their business model revolves around providing gaming content and platforms to operators, leveraging NOVOMATIC's brand and resources. The company demonstrates competitive advantages through a diverse game portfolio, technological innovation, and compliance certifications. Revenue streams likely include licensing, platform services, and content delivery. The partnership ecosystem includes social media channels and industry certifications. Growth indicators are positive with continuous new game releases and global office locations. Operationally, the company maintains a professional online presence with clear navigation and comprehensive content.

Security posture

The website exhibits a mature security posture with enforced HTTPS, presence of key security headers, and cookie consent mechanisms aligned with GDPR. No exposed sensitive data or vulnerable libraries were detected. However, the absence of a public security policy, incident response information, and vulnerability disclosure reduces transparency. The WHOIS data is missing, which may indicate privacy protection but also reduces domain registration trust. Overall, the security maturity is good but could be improved by publishing explicit security documentation and providing direct security contacts.

Recommendations

  1. Publish a detailed security policy and incident response plan on the website.
  2. Implement and publicize a vulnerability disclosure program or security.txt file.
  3. Provide a dedicated security contact email for incident reporting.
  4. Regularly audit and update third-party scripts and libraries to mitigate vulnerabilities.
  5. Enhance transparency by including WHOIS registrant information or justifying privacy protection.

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.
