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

HealthCare.gov is the official US government website providing access to the Health Insurance Marketplace®, enabling US residents to explore and enroll in health insurance plans. It serves as a critical platform for facilitating health coverage under government regulations and subsidies. The website is positioned as the primary government resource for health insurance enrollment, targeting individuals and families seeking affordable healthcare options. Technically, the site is built using modern web technologies including Gatsby and React, ensuring fast performance, excellent mobile optimization, and strong accessibility compliance. The site employs HTTPS and appears to follow good security practices, although explicit security headers and incident response information are not visible in the provided data. From a security perspective, the website demonstrates a strong posture typical of government domains, with no detected vulnerabilities or blocking mechanisms. The WHOIS data is privacy protected, which is common for government domains, and does not detract from the legitimacy of the site. However, publishing explicit security policies and vulnerability disclosure programs would enhance transparency. Overall, HealthCare.gov is a highly credible, professional, and secure government platform essential for US healthcare consumers. Strategic recommendations include enhancing public security disclosures, adding explicit privacy and cookie policies on the landing page, and ensuring comprehensive security headers are implemented to further strengthen the security posture.

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. Security headers

    Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

  2. 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

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

HealthCare.gov operates as a government service platform facilitating health insurance enrollment for US residents. Its market position is unique as the official US government health insurance marketplace, providing access to subsidies and coverage plans. The business model is service-oriented, funded and operated by the US government, targeting individuals and families needing health insurance. The platform's competitive advantage lies in its official status, trustworthiness, and comprehensive coverage options. Partnerships likely include federal and state health agencies. Growth indicators include ongoing government healthcare initiatives and policy changes. The website's operations reflect a mature, enterprise-level government service with a focus on accessibility and user experience.

Security posture

The security maturity of HealthCare.gov is high, consistent with government standards. The site uses HTTPS and likely enforces secure cookies and session management. No exposed sensitive data or vulnerable libraries were detected in the provided HTML. However, explicit security headers such as Content-Security-Policy and Strict-Transport-Security were not visible and should be confirmed. There is no public incident response or vulnerability disclosure information found, which is a gap in transparency. GDPR compliance is not explicitly stated but likely considered given US government standards. Overall, the site demonstrates strong security culture but could improve by publishing security policies and disclosure programs.

Recommendations

  1. Publish a comprehensive security policy and incident response information on the website.
  2. Implement and disclose a vulnerability disclosure program or security.txt file.
  3. Ensure all recommended security headers (CSP, HSTS, X-Frame-Options) are implemented and visible.
  4. Add explicit privacy and cookie policies accessible from the landing page.
  5. Maintain and regularly audit accessibility and mobile optimization to uphold user experience standards.

Technical notes

Notes

HealthCare.gov is built on a modern technology stack using Gatsby and React, which supports fast loading times and excellent mobile responsiveness. The site uses semantic HTML and CSS with accessibility best practices evident in the markup. Performance is optimized with modern frameworks, and SEO is well supported by meta tags and Open Graph data. There is no evidence of legacy or vulnerable libraries. Hosting details are not explicit but likely government-managed infrastructure. Technical risks are minimal, but continuous 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.
