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

Blue Cross and Blue Shield of Illinois (BCBSIL) is a major health insurance provider serving the entire state of Illinois with a broad range of health plans including individual, family, Medicare, Medicaid, and employer plans. The company is a large, customer-owned insurer with a significant market presence, serving over 8.9 million members. The website reflects a mature digital presence with comprehensive content, clear navigation, and integration of multiple health insurance products and member resources. Technically, the site is built on Adobe Experience Manager and leverages various Adobe marketing and analytics tools, but suffers from a critical security issue due to the absence of a valid SSL certificate and lack of HTTPS support, which significantly impacts its security posture. Privacy compliance is basic with a privacy policy present but no visible cookie consent mechanism. Overall, the site is professional and trustworthy but requires urgent security improvements to protect user data and maintain trust.

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

BCBSIL holds a dominant position in the Illinois health insurance market as the largest provider of health benefits statewide. Its business model focuses on providing comprehensive health insurance products across multiple segments including individuals, families, Medicare and Medicaid recipients, and employers. The company benefits from a strong brand, extensive provider networks, and a commitment to community impact and member services. The website's content and structure indicate a focus on accessibility, member engagement, and transparency. Partnerships with payment and service providers are evident, enhancing operational capabilities. The company is part of Health Care Service Corporation, indicating a large enterprise backing.

Security posture

The website's security posture is currently weak due to the lack of a valid SSL certificate and absence of HTTPS support, exposing users to potential data interception risks. While HSTS is enabled with preload, the absence of TLS protocols and cipher suites renders this ineffective. No critical vulnerabilities like Heartbleed or POODLE are detected, but the missing SSL is a critical issue. No explicit security policies or incident response contacts are found on the site. The site uses modern marketing and analytics tools but lacks visible cookie consent mechanisms, which may impact privacy compliance. Immediate remediation of SSL/TLS issues is recommended to safeguard user data and comply with security best practices.

Recommendations

  1. Install and maintain a valid SSL/TLS certificate to enable HTTPS across the entire site.
  2. Enable modern TLS protocols (TLS 1.2 and 1.3) and strong cipher suites to secure communications.
  3. Implement OCSP stapling and session resumption to enhance security and performance.
  4. Add a visible cookie consent mechanism to comply with privacy regulations and improve user trust.
  5. Publish explicit security policies and incident response contact information to demonstrate security maturity.
Technical notes

Notes

The website is built on Adobe Experience Manager, a robust enterprise CMS, and integrates multiple Adobe marketing and analytics tools such as Adobe Dynamic Tag Manager and Helix RUM. Hosting is on Amazon AWS, providing scalable infrastructure. The site has a rich content structure with comprehensive navigation and is optimized for mobile devices. However, the performance is slow with a load time of approximately 24.5 seconds and a large page size (~500KB). There is no valid SSL certificate, and no TLS protocols or cipher suites are enabled, which is a significant technical risk. Accessibility and SEO optimizations are good, but technical debt exists in security configuration. Modernization efforts should prioritize security and performance improvements.
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.
