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

FanDuel, operated by Betfair Interactive US LLC and a subsidiary of Flutter Entertainment plc, is a leading US-based online platform offering daily fantasy sports, sports betting, and online casino gaming. The website targets adult users in multiple US states where gambling is legal, providing a comprehensive suite of gaming products including sportsbook, casino, fantasy sports, horse racing betting, and streaming content via FanDuel TV. The platform is well-positioned in the market with extensive state coverage and a strong brand presence supported by partnerships with major payment providers and responsible gaming initiatives. Technically, the website leverages modern web technologies such as React and Next.js, integrates multiple analytics and marketing tools including Amplitude, Google Tag Manager, and various social media pixels, and employs a responsive design optimized for mobile devices. The site demonstrates good SEO practices and accessibility at a basic level, with fast to moderate performance. From a security perspective, FanDuel enforces HTTPS, implements key security headers, and shows no signs of exposed sensitive data or vulnerabilities. However, the absence of a visible cookie consent mechanism and explicit incident response contacts indicates areas for improvement in privacy compliance and security transparency. Overall, FanDuel presents a professional, trustworthy, and legally compliant online gambling platform with a mature digital presence. Strategic enhancements in privacy consent and incident response disclosures would further strengthen its security posture and regulatory 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

3 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 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

  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

FanDuel operates in the regulated US gambling market, offering a diversified product portfolio that includes sportsbook betting, online casino games, fantasy sports, and horse racing wagering. Its business model relies on user engagement through promotions, content streaming, and affiliate marketing. The company benefits from its parent Flutter Entertainment's global gambling expertise and financial backing. FanDuel's competitive advantages include broad state licensing, a strong brand, and integrated technology platforms. The target customers are adult sports fans and gamblers in legal jurisdictions. Growth indicators include expansion into new states and continuous product innovation. The partnership ecosystem includes major payment processors and advertising networks, enhancing user trust and operational capabilities.

Security posture

FanDuel exhibits a mature security posture with enforced HTTPS, comprehensive security headers, and no detected vulnerabilities in the analyzed content. The site integrates multiple third-party analytics and marketing scripts, which are common in the industry but require ongoing monitoring for security risks. The lack of a published vulnerability disclosure policy or security.txt file and absence of explicit incident response contact details represent gaps in transparency and readiness. Privacy compliance is partially addressed with a comprehensive privacy policy but lacks visible cookie consent mechanisms. Overall, the security culture appears strong but could benefit from enhanced user-facing security communications and consent management.

Recommendations

  1. Implement a visible and user-friendly cookie consent banner to comply with GDPR and other privacy regulations.
  2. Publish a vulnerability disclosure policy or security.txt file to encourage responsible reporting of security issues.
  3. Provide explicit incident response contact information, such as a dedicated security or abuse email address.
  4. Enhance website accessibility features to improve compliance with standards and user experience for all users.
  5. Regularly audit and update third-party scripts and tracking pixels to minimize security and privacy risks.

The site loads multiple fonts and CSS stylesheets efficiently and uses a responsive grid layout for mobile optimization. Performance is moderate, with potential improvements in script loading and caching. No CMS is explicitly detected, suggesting a custom or proprietary content management approach.

Overall, the technical infrastructure supports a high-quality user experience with room for optimization in accessibility and privacy compliance.
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.
