Low risk. 4 critical or high findings in Security headers and GDPR outside view.
The Centers for Disease Control and Prevention (CDC) operates as the leading national public health institute in the United States, providing authoritative health information, disease prevention guidance, and outbreak monitoring. The website serves a broad audience including the general public, healthcare professionals, researchers, and policymakers. It is a government agency under the U.S. Department of Health and Human Services, offering extensive resources on health topics, vaccination, and public health research. Technically, the CDC website employs modern web technologies such as Bootstrap 5, jQuery, and Google Tag Manager, ensuring a responsive and accessible user experience. The site is well-structured with comprehensive metadata and SEO optimization, supporting efficient navigation and content discovery. The use of sanitization libraries like DOMPurify indicates attention to security in input handling. From a security perspective, the site enforces HTTPS and employs best practices such as input sanitization. However, explicit security headers are not detected in the HTML content, suggesting room for improvement. Privacy policies and vulnerability disclosure information are present, reflecting a mature compliance posture. No critical vulnerabilities or suspicious content were identified. Overall, the CDC website demonstrates a high level of professionalism, trustworthiness, and compliance with privacy and security standards. The domain is a .gov domain, which is tightly regulated, further supporting legitimacy. The site is well-positioned to serve its public health mission effectively.
Scanned
NIS2 Art. 21(2)
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.

Each check with its score, findings and the evidence it collected.
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.

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.
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.

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.
Automated reading of the public site. Ratings are indicative.
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.
