Cleveland Clinic is a globally recognized non-profit academic medical center founded in 1921, providing comprehensive clinical and hospital care, research, education, and health information services. The website reflects its leadership position in healthcare with extensive patient resources, provider tools, and international subsidiaries.

The site is well-optimized for mobile and accessibility, with clear navigation and professional design. From a security perspective, the website enforces HTTPS and integrates reputable third-party security and analytics tools. While explicit security headers are not fully confirmed, no critical vulnerabilities or exposed sensitive data were detected. Privacy compliance is strong, with comprehensive privacy and cookie policies and consent mechanisms in place, aligning with GDPR requirements. However, incident response and vulnerability disclosure information are not publicly visible, representing an area for improvement. Overall, the website demonstrates a high level of professionalism, trustworthiness, and technical sophistication, supporting Cleveland Clinic's brand as a leading healthcare institution. The domain WHOIS data is unavailable publicly, likely due to privacy protection, which is justified given the organization's profile.

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.

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

Cleveland Clinic operates as a large enterprise in the healthcare sector, targeting patients, visitors, and medical professionals worldwide. Its business model centers on providing high-quality clinical care, conducting cutting-edge research, and offering educational programs. The organization maintains a strong market position with multiple international subsidiaries and a broad service portfolio including virtual care and health information dissemination. The website supports recruitment, patient engagement, and professional collaboration, indicating diversified revenue streams and growth potential. Partnerships with specialized domains enhance its ecosystem, while consistent branding and comprehensive content reinforce its authoritative presence.

Security posture

The website exhibits a mature security posture with enforced HTTPS, absence of exposed sensitive data, and use of trusted third-party security and analytics services. Security headers are partially inferred but not explicitly confirmed, suggesting room for enhancement. No visible vulnerabilities or insecure forms were detected. Privacy policies and cookie consent mechanisms indicate compliance with data protection regulations. However, the lack of publicly available incident response contacts and vulnerability disclosure policies may limit rapid response capabilities and transparency. Overall, the security maturity is high but could benefit from explicit security header implementation and published security policies.

Recommendations

  1. Implement and verify comprehensive security headers including X-Frame-Options and X-Content-Type-Options.
  2. Publish a clear vulnerability disclosure policy and incident response contact information to enhance transparency and trust.
  3. Regularly audit third-party scripts and dependencies to mitigate supply chain risks.
  4. Enhance visibility of data protection officer or privacy contact details to support GDPR compliance.
  5. Maintain continuous monitoring and update security practices aligned with evolving threats and compliance requirements.

Technical notes

Notes

The website is built on a modern technology stack including jQuery, Google Tag Manager, Optimizely, Adobe DTM, and Microsoft Omnichannel Live Chat, hosted likely on Microsoft Azure infrastructure. The use of Sitecore CMS is inferred from internal index names and script paths. Performance is optimized with CDN usage and asynchronous script loading. The site is mobile responsive with good accessibility features and SEO optimization through structured data and meta tags. Technical debt appears minimal, though continuous modernization and security header enhancements are recommended to maintain robustness and 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.
