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.

    • Critical

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

  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

Flutter Entertainment's market position as a global leader is reinforced by its extensive brand portfolio and presence in multiple regulated markets. The business model focuses on online sports betting and iGaming, supported by B2B services and data offerings. The company benefits from access to deep capital markets, including US listings, and maintains active investor relations with embedded feeds and regulatory disclosures. The target audience includes sports bettors and online gaming customers globally, with a strong emphasis on responsible gambling and sustainability. Partnerships with technology and analytics providers such as Q4 and Microsoft enhance operational capabilities. The website content and structure support investor confidence and customer engagement.

Security posture

The website employs HTTPS and integrates cookie consent management via Cookiebot, indicating compliance with privacy regulations. Microsoft Application Insights is used for telemetry, enhancing monitoring capabilities. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of explicit security headers and a public incident response policy suggests room for improvement. No direct contact channels for security incidents were found. Overall, the security posture is good but could be strengthened by publishing security policies, implementing recommended HTTP security headers, and providing clear incident response contacts.

Recommendations

  1. Implement and enforce HTTP security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Publish a dedicated security policy and incident response page including contact channels for reporting security issues to improve transparency and readiness.
  3. Regularly audit and update third-party scripts and libraries to mitigate risks from vulnerable components.
  4. Enhance cookie consent transparency by providing detailed information on data retention and third-party data sharing practices.
  5. Maintain and promote trust signals such as certifications, awards, or compliance badges to reinforce business credibility.

Technical notes

Notes

The website is built on Umbraco CMS and uses modern JavaScript libraries including jQuery and Swiper.js for UI components. Analytics and telemetry are managed via Google Tag Manager and Microsoft Application Insights, with Cookiebot handling cookie consent compliance. The site is hosted on Azure infrastructure, inferred from cookie providers and script sources. Performance is moderate with lazy loading of images and videos, and mobile optimization is good with responsive design elements. Accessibility features are present, including ARIA roles and keyboard navigation support. SEO is supported by canonical tags, meta descriptions, and Open Graph metadata. Technical risks are minimal but could be reduced by implementing additional security headers and ensuring all third-party integrations are up to date.
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.
