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

Zwift holds a strong market position as a pioneer in virtual cycling, combining software and hardware to deliver immersive fitness experiences. Its business model centers on subscription revenue complemented by hardware sales. The company benefits from a global user base and a rich ecosystem of partnerships and integrations. The website's content and testimonials reinforce its credibility and community focus. Growth indicators include continuous product updates and active marketing campaigns. The absence of direct contact information on the main site suggests a focus on digital self-service and support portals. Zwift's strategic use of analytics and advertising platforms supports targeted user engagement and retention.

Security posture

The website demonstrates a mature security posture with HTTPS and cookie consent mechanisms in place. The use of multiple analytics and marketing scripts is managed through consent, aligning with GDPR requirements. No direct vulnerabilities or exposed sensitive data were detected in the HTML content. However, explicit security headers like Content-Security-Policy and X-Frame-Options were not confirmed and should be audited. Incident response and security policy information are not publicly visible, indicating potential areas for transparency improvement. Overall, Zwift maintains good security hygiene appropriate for its industry and scale.

Recommendations

  1. Conduct a thorough audit to ensure all recommended security headers (CSP, X-Frame-Options, X-Content-Type-Options) are implemented.
  2. Enhance visibility of security policies and incident response contacts to build user trust and compliance.
  3. Regularly update and monitor third-party libraries and analytics tools to mitigate vulnerabilities.
  4. Consider publishing a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  5. Maintain and improve privacy compliance documentation and user consent mechanisms as regulations evolve.

Technical notes

Notes

Zwift's website is built on a modern React-based framework (Next.js) with a headless CMS (Prismic) for content management. It employs a robust tech stack including Segment, Amplitude, Google Tag Manager, and Hotjar for analytics and user behavior tracking. The site is well-optimized for performance and mobile responsiveness, with extensive use of CDN-hosted assets and lazy loading. The integration of TrustArc for cookie consent reflects a commitment to privacy compliance. Hosting appears to be on a scalable cloud infrastructure with CDN support. Technical risks are minimal but include the need for continuous dependency management and security header enforcement to maintain a strong security posture.
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.
