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

4 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1

  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

  3. 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

Jefferson Health operates in the healthcare sector as an essential entity with an enterprise scale. Its business model focuses on providing comprehensive patient care through multiple hospitals, outpatient centers, and specialty clinics. The organization targets patients and healthcare consumers in its regional market, leveraging partnerships with entities like Lehigh Valley Health Network and Thomas Jefferson University. Revenue streams likely include patient services, insurance reimbursements, and philanthropic contributions. The website's integration with patient portals and scheduling systems indicates a focus on digital patient engagement and operational efficiency. Growth indicators include recent leadership appointments and strategic initiatives such as AI adoption. The partnership ecosystem is diverse, involving academic, clinical, and community organizations, enhancing its market position and service offerings.

Security posture

The website exhibits a mature security posture with HTTPS enabled and no exposed sensitive data in the HTML content. Use of third-party analytics and marketing scripts is evident, but no vulnerable libraries or insecure forms were detected. However, the absence of explicit security headers like Content-Security-Policy and X-Frame-Options suggests room for improvement. No public security policy or incident response information was found, which could enhance transparency and readiness. Privacy policies and cookie consent mechanisms are present and indicate GDPR compliance, supporting data protection efforts. Overall, the security maturity is good but could benefit from formalized policies and enhanced header configurations to mitigate risks further.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-XSS-Protection to strengthen browser security.
  2. Publish a dedicated security policy and incident response page to improve transparency and preparedness.
  3. Establish a vulnerability disclosure program or security.txt file to facilitate responsible reporting of security issues.
  4. Regularly audit and update third-party scripts and libraries to minimize exposure to vulnerabilities.
  5. Enhance monitoring and logging capabilities to detect and respond to potential security incidents promptly.

Technical notes

Notes

The website is built on a modern technology stack featuring React and Adobe Experience Manager, enabling dynamic content delivery and a responsive user interface. Integration with multiple analytics and marketing platforms such as CrazyEgg, Freshpaint, Qualtrics, and Google Tag Manager supports data-driven decision-making. The site demonstrates good mobile optimization and accessibility features, contributing to a positive user experience. Performance is moderate, with potential for optimization in loading times and script management. The use of a robust CMS facilitates content management but requires ongoing maintenance to avoid technical debt. Hosting details are not explicitly identified, but the infrastructure supports enterprise-level operations. Overall, the technical foundation is solid with opportunities for incremental improvements in performance and security.
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.
