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 occupies a dominant position in the online sports betting and iGaming sector, leveraging a broad brand portfolio to capture diverse customer segments globally. Their competitive advantages include scale, brand diversity, and a challenger mindset focused on innovation and responsible gaming. Revenue streams are primarily from online betting and gaming services, supported by B2B offerings such as sportsbook solutions and data services. The company actively engages investors with transparent regulatory news, SEC filings, and share price information. Partnerships with responsible gambling organizations and clear communication of support resources further enhance their market reputation. Growth indicators include expanding US market presence and continuous product innovation.

Security posture

The website exhibits a solid security posture with mandatory HTTPS enforcement and integration of cookie consent tools to comply with privacy regulations. Use of Microsoft Application Insights provides telemetry and monitoring capabilities. No critical security issues or vulnerabilities were identified in the HTML content. However, explicit security policies, incident response contacts, and vulnerability disclosure mechanisms are not publicly disclosed, representing potential gaps in transparency. The absence of a security.txt file and dedicated security contact channels limits external vulnerability reporting. Overall, the security maturity is good but could be improved by formalizing and publishing comprehensive security policies and response procedures.

Recommendations

  1. Implement and publicly disclose comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  2. Publish an incident response policy and provide dedicated security contact channels such as security@ or abuse@ email addresses.
  3. Create and maintain a security.txt file to facilitate responsible vulnerability disclosure.
  4. Enhance transparency around data protection officer contact information and data handling practices.
  5. Continue to strengthen trust signals by obtaining and displaying relevant security and privacy certifications.

Technical risks are minimal, but ongoing monitoring and updates are recommended to maintain security and performance.
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.
