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

2 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.

    • 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.

    • 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

Unibet holds a strong market position as a leading online gambling operator in the Netherlands, supported by multiple certifications and memberships in industry bodies like EGBA and IBIA. Its business model focuses on providing a comprehensive gambling experience with tailored promotions and a dedicated mobile app. The company leverages partnerships with payment providers and regulatory authorities to ensure compliance and customer trust. The platform's extensive service offerings and positive player feedback indicate a robust customer base and growth potential. Strategic observations include continued investment in mobile technology and responsible gambling initiatives to maintain competitive advantage.

Security posture

The website exhibits a high level of security maturity with enforced HTTPS, comprehensive security headers, and no visible exposure of sensitive data. The presence of certifications such as eCOGRA and licensing by the Dutch regulator further reinforce its compliance and security stance. However, explicit security policies and incident response contacts are not publicly detailed, representing an area for improvement. No known vulnerabilities or outdated libraries were detected in the provided content. The platform's security culture appears strong, with emphasis on player protection and responsible gambling.

Recommendations

  1. Publish a dedicated security policy page including incident response and vulnerability disclosure contacts.
  2. Implement and publicize a security.txt file to facilitate responsible vulnerability reporting.
  3. Regularly audit and update third-party libraries and dependencies to mitigate emerging vulnerabilities.
  4. Enhance transparency around data retention policies and privacy compliance measures.
  5. Continue to strengthen responsible gambling tools and user education to reduce risk of problem gambling.

Technical notes

Notes

The website is built on a modern React-based front-end with CSS-in-JS styling, supporting progressive web app features for enhanced mobile experience. The site loads efficiently with optimized assets and responsive design. SEO best practices are followed with appropriate meta tags and structured data. Accessibility considerations are evident but could be further enhanced with ARIA landmarks and keyboard navigation improvements. Hosting details are not explicit but the site uses secure HTTPS and strong security headers. Technical risks are minimal, with opportunities to improve documentation and transparency around security and privacy practices.
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.
